5. INTRODUCTION

5.1 Measuring humidity, basic principles

Humidity is always present in the atmosphere in the form of water vapor. The percentage of water vapor per volume of air varies. Saturation vapor pressure at any given air temperature is the maximum partial pressure of water vapor

(its gas phase) over an even surface of water (its liquid phase). This is tem perature-dependent; at each temperature there is a maximum quantity of water vapor that can be contained in a defined quantity of air. Atmospheric humidity can be specified either as absolute humidity or as relative humidity. In these operating instructions humidity variables will be given first using the new symbols defined in VDI/VDE 3514 and then in brackets using the old abbreviations seen in tables issued by the Deutscher Wetterdienst (German Meteorological Service).

Absolute humidity d

v

(AH) is also referred to as water vapor content. This is the weight of water vapor contained in one m3 of a mixture of water vapor and air. Since 1 m3 will, depending on pressure and temperature, contain a different air mass, it is usually easier to refer to absolute humidity per 1 kg of dry air. This variable is known as the mixture ratio r (MH).

Relative humidity U w

(RH) is the ratio of the water vapor’s partial pressure

e´ (VP) to the saturation vapor pressure ew´ (SVP) in a mixture of water vapor and air at air temperature t (TT). The temperature at which saturation occurs

(VP=SVP, RH=100%) is known as the dewpoint temperature t soon as the air falls below this dewpoint temperature the water vapor (gas phase) condenses into droplets of water (liquid phase). Enthalpy h (En) is the thermal content in the mixture of water vapor and air.

d

(DT). As

5.2 Psychrometer

Measuring principle

A psychrometer is a precision instrument incorporating two highly accurate temperature sensors; it is used to determine all the usual humidity variables.

One of these sensors is covered in a cotton sheath; this must be kept permanently moist with water from a reservoir and cooled by means of a current of air. When the power supply is connected and the integrated fan starts operating, the moistened temperature sensor will, depending on air temperature and humidity, cool down by a measurable amount. Based on this psychrometric temperature difference the water vapor’s partial pressure e´ and thus all the variables associated with atmospheric humidity can be calculated.

1036

Measuring instrument

5.3 Measuring instrument

High-precision measuring instrument ALMEMO ® 1036-2 incorporates two electrically isolated measuring inputs for Pt100 sensors with a resolution of 0.001 K.

The measured values obtained are larger than the 16-bit numbers provided by other ALMEMO ® devices. This device cannot therefore support the standard functions usually provided (limit values, measured value correction, scaling, or analog output).

The Pt100 psychrometer can be used to measure very accurately both dry temperature and humid temperature and thus calculate all the usual humidity variables on the basis of formulae as per Dr. Sonntag and the enhancement factor as per W. Bögel (correction factor fw(t,p) for real mixed gas systems).

These calculations must take account of atmospheric pressure; for this purpose the device incorporates as standard an atmospheric pressure sensor.

The measuring range and accuracy of this device are thus much greater than with previous systems. The atmospheric pressure measured can also be used as an additional climate variable.

Device 1036-2 can also have two digital D6 humidity sensors connected, namely NTC psychrometer FNAD36-3, and capacitive humidity sensor

FHAD46-RS (for up to maximum 200 °C). Both use exactly the same calculation principles and internal atmospheric pressure compensation as the Pt100 psychrometer.

To facilitate operation the device incorporates an illuminated LCD graphics display and a keypad with softkeys and cursor block. The device incorporates three output sockets for connecting interface cables, a memory connector, or a mains unit..

5.4 Sensor programming

Measuring ranges

Measuring instrument ALMEMO ® 1036, operating in particular with high-precision Pt100 temperature sensors, attains a resolution of 0.001 K without any linearization errors; this is because the temperature values are very accurately calculated using the appropriate formulae. It is thus ideally suitable as a reference device - not only for temperatures but also, with the psychrometer, for all the usual humidity variables.

Or you can connect and program our latest D6 digital humidity sensors. This device - unlike standard ALMEMO ® V6 devices - can even display individual range abbreviations; these would otherwise have to be transferred via interface to the PC.

Measured channel designation

Each sensor is identified by means of a 10-character alphanumeric name.

These names are entered via the keypad or the interface and appear in the display, in the printout, and on the computer screen.

Correction of measured values

The measured value on each measuring channel can be corrected to zero.

The sensors can be adjusted on leaving our factory in several aspects; i.e. the applicable error curve is saved in the connector.

ALMEMO

®

1036 9

5. Introduction

For digital D6 sensors the standard correction functions, zero-point and gain, are also provided.

All programmed sensor parameters are saved in the connector and are automatically restored as and when a sensor is plugged in.

5.5 Measuring operation

The user can move forwards or backwards from one measuring channel to the next using the keypad. Data is output on the display at a rate of 1.25 measuring operations per second (mops).

Atmospheric pressure compensation

Humidity variables are heavily dependent on atmospheric pressure. To avoid errors of this nature the device incorporates its own atmospheric pressure sensor for compensating its measured values. All D6 sensors incorporate their own atmospheric pressure sensor.

Measured value smoothing

For both measuring channels measured values of an unstable, fluctuating nature can be smoothed by taking a sliding average over a number of values programmable from 2 to 99. With D6 sensors a separate time constant can be programmed. (see sensor instructions)

Maximum and minimum values

For each measuring operation the maximum value and minimum value are acquired and saved to memory. These values can then be displayed, printed out, or deleted from memory.

Measured value memory

Up to 100 measured values can be saved manually. This data can then be shown on the display or output via the interface.

Operation

All measured values and function values can be displayed in different menus on the dot-matrix LCD screen. Seven keys (four of them softkeys) are available for operating the device. In this way the device and sensors can be programmed.

Output

All data logs, menu functions, saved measured values, and stored program parameters can be output to any peripheral equipment. Using the appropriate interface cable any of interfaces RS232, RS422, USB, or Ethernet can be used.

Measured data can be output in list, column, or table format. Files in table format can be processed directly using any standard spreadsheet software. The print header can be programmed to refer specifically to your company or to a specific application.

Data logger

The device can, by fitting an external memory connector with a micro-SD memory card, be upgraded to a high-capacity data logger. Using this external memory connector (available as an accessory) files can be read out very quickly via any standard card reader. As soon as this is connected two additional menus with all the necessary parameters e.g. date, time-of-day, cycle, start time, end time, memory capacity, file name etc. are available.

7. Power supply

7. POWER SUPPLY

Power can be supplied to the measuring instrument in any of the following ways :

3 AA alkaline batteries (included in delivery)

Mains adapter, 12 V, 1 A, with ALMEMO ® plug ZA 1312-NA7

Power supply cable, electrically isolated (10 to 30 VDC, 0.25 A) ZA 2690-UK

Our product spectrum covers all the appropriate accessories.

7.1 Battery operation and supply voltage monitoring

he device is normally powered by 3 AA alkaline batteries. At a current consumption of on average 25 mA, these last for an operating time of approx. 100 hours. If the display illumination is left switched ON, this operating time will be reduced to approx. 50 hours. The operating voltage can be checked in the

´

Info

´ menu; this gives you a basis for estimating the remaining operating time. (see XREF)

As soon as the remaining battery capacity drops to approx. 10%, the battery symbol

´´µµµµµµµµµ¶

in the status bar of the display will start to flash. If the batteries are completely discharged, i.e. down to approx. 3V, the device will switch OFF automatically but measured data already acquired will be saved. (see 7.5)

To replace used batteries first unscrew the battery compartment cover (7) on the rear of the device. When inserting batteries ensure that their polarity is correct.

7.2 Mains operation

To power this device from an external source preferably use mains adapter ZA

1312-NA7 (12 V / 1 A); connect this to the DC socket (3).

Please ensure that the mains voltage is correct.

7.3 External DC voltage supply

The DC socket (3) can also be used to connect another DC voltage, 6 to 13 V

(minimum 200 mA). ALMEMO

®

connector ZA1012-FS should be used. If, however, the power supply has to be electrically isolated from the sensors or if a larger input voltage range (10 to 30 V) is required, then electrically isolated supply cable ZA 2690-UK must be used. It will then be possible to use the measuring instrument in a 12-volt or 24-volt on-board supply system.

Switching ON / OFF, reinitialization

7.4 Switching ON / OFF, reinitialization

To switch the device ON press and release

ON PROG r

(6) located in the middle of the cursor block. The first thing to appear in the display is always the measuring menu.

To switch OFF press and hold down the same key(s)

ON PROG r

. When the device switches OFF all saved values and settings are retained intact. (see 7.5)

If interference (e.g. electrostatic) or a malfunction (e.g. battery failure) causes the device to behave abnormally, it can be reinitialized. To activate RESET press and hold down key F1 r when switching on. To completely reinitialize all device programming (including device designation) to the factory defaults keep key F2 r pressed when switching on. In so doing certain parameters will be lost or be returned to their defaults : Language = German, illumination = OFF.

7.5 Data buffering

The sensor's programming is stored in the EEPROM on the sensor connector; the device's calibration values and programmed parameters are stored in the

EEPROM on the instrument itself; in the event of failure both will be retained intact. When the device is simply switched off, the date and time-of-day settings and the individual value memory on the data logger are retained intact; however, if the device is reset or the batteries are replaced, this will all be lost.

8. CONNECTING SENSORS / TRANSDUCERS

The following special devices can be connected at input sockets M0 and M1

(1) on the measuring instrument : stationary high-precision psychrometer FPA836-3P3, digital D6 NTC psychrometer FNAD46-3, or D6 humidity sensor FHAD36-RS. Or of course a high-precision Pt100 sensor FPA923-L0250 with range P314 (0.001K) can be used.

8.1 Sensors / transducers

All the afore-mentioned sensors with an ALMEMO

®

plug have their measuring range and units already programmed and can thus be connected to the measuring sockets without any further adjustment. A mechanical coding system ensures that sensors and output modules can only be connected to the correct sockets. All ALMEMO ® plugs incorporate two snap-lock levers; these snap into position as soon as the plug is inserted into the socket, thus preventing unintended disconnection if the cable is pulled accidentally. To withdraw the plug both these levers must first be pressed in at the sides.

Splash-proof variants of devices in the ALMEMO coated ALMEMO ® plugs incorporating a double sealing lip specially designed to protect the socket unit against penetration by splashing water. For any unused sockets protective stoppers are available.

® 1036 series are also available as options. For this purpose new sensors are now available with spray-

8.2 Stationary high-precision psychrometer FPA 836-3P3

Filling the water reservoir

1. Undo the refill screw

2. Top up the reservoir with distilled water using the squeeze bottle supplied

3. Tighten the refill screw again and perform measuring operation

The water in the reservoir may in certain circumstances become contaminated. The reservoir must be cleaned therefore about every 6 weeks. In the event of long periods of inactivity or for transport purposes the reservoir should be emptied completely.

Changing the wick

If the cotton wick becomes dirty or encrusted it will no longer absorb moisture properly; as a result measured values may be falsified. It should therefore be replaced at regular intervals (depending on how clean the air and water are).

1. Emptying the reservoir (see above)

2. Unscrew the water reservoir lid

3. Unscrew the motor / sensor retaining plate and withdraw the old wick from the humid temperature (HT) sensor

4. From the side of the reservoir insert the new wick into the psychrometer tube and pull over the HT sensor

5. Screw the motor / sensor retaining plate back again

6. From the side of the reservoir adjust the wick, screw the reservoir lid back in position, and refill the reservoir.

Using the psychrometer

To obtain reliable results it is very important that the psychrometer be operated properly. Please ensure therefore that you always comply with all the following advisory notes :

1. After the fan starts up it will take approx. 20 to 30 seconds before the humid temperature sensor is sufficiently cooled. Only after this period will humidity values be stable.

14 ALMEMO

®

1036

Stationary high-precision psychrometer FPA 836-3P3

2. Ensure that the humidity sensor is always sufficiently moistened. If you are unsure whether there is sufficient moisture carry out a visual inspection of both the cotton sheath and the wick itself. To moisten the wick use distilled water only. Ordinary water may leave calcified deposits on the wick.

3. If the wick no longer absorbs water properly (through dirt or dryness), replace its cotton sheath.

4. Air velocity at the air intake must be minimum 2 m/s. Ensure therefore that the air intake is always free and unobstructed.

5. Avoid inadvertently warming the probe head from external heat sources or your own body heat.

8.3 Measuring sockets, measuring channels

Measuring instrument ALMEMO ® 1036 has 2 measuring sockets M0 and M1

(1) and to each of these up to 4 measuring channels can be allocated.

Device-internal channels

This device also provides 4 device-internal additional channels. These can be used, as and when necessary, to program the battery voltage, the device-internal atmospheric pressure, or a function channel Differential . see 14.3, 11.3.

Atmospheric pressure compensation

11.2 Atmospheric pressure compensation

Certain measured variables are affected by the ambient atmospheric pressure; with a psychrometer all are affected whereas with a capacitive humidity sensor only MH and En; in both cases any pronounced deviation from standard pressure (1013 mbar) may lead to measuring errors.

e.g. Error per 100 mbar Compensation range

Relative humidity, psychrometric approx. 2% 500 to 1500 mbar

Mixture ratio approx. 10% Vapor pressure VP up to 8 bar

To completely avoid errors caused by atmospheric pressure deviations (especially at significant altitudes above sea level), this high-precision instrument incorporates a pressure sensor for use with the Pt100 psychrometer. D6 sensors have their own atmospheric pressure sensors integrated in the ALMEMO

Sensor display menu lists the Atmospheric pressure function.

In special cases (e.g. when measuring in conduits) the appropriate atmospheric pressure can also be programmed at this juncture. (see 9.5)

To switch back to the measured value the programming value must be deleted again.

11.3 Differential measurement

If two sensors with the same units and same decimal point position are connected at measuring sockets M0 and M1, the difference below device-internal measuring point M02. M02 = M01 - M00 may be programmed (see 8.3)

14. SENSOR PROGRAMMING

Since on ALMEMO

ALMEMO ®

® devices all sensor programming is stored in the

connector itself, the user will not normally need to reprogram each time. However, with humidity sensors it is necessary sometimes to program other humidity ranges than those provided as standard. Each channel can also be assigned a designation or smoothing.

In the Sensor programming menu these channel parameters can (so long as the appropriate sensor connector is plugged in) be entered, viewed, checked, and modified via the keypad.

This designation is displayed in the functions menu. In outputs via the interface the measuring channel designation appears in the program header as Designation.

To enter name in Designation function see 9.5 Designation: Humid temp

14.2 Locking the sensor programming

The functional parameters for each measuring channel are protected by means of the locking mode; this can be set to the desired locking level (see

14.3 Selecting a measuring range

If you want to change a measuring range you must first clear the locking mode for the connectors concerned, i.e. set to 0. (see 14.2) To activate a new measuring channel you must first activate all channels by pressing <MALL> , then select the required input channel, and then enter the range.

14.4.2 Multi-point adjustment

The sensor’s measuring accuracy can be optimized by storing in the connector

EEPROM a correction curve for the Pt100 dry temperature and humid temperature sensors. In a calibration laboratory any deviations from the ideal setpoint can be measured at various points; then, with the AMR-Control, this information can be stored in the sensor and interpolated on a linear basis for subsequent measuring operations.

14.4.3 Smoothing by means of a sliding average

When measuring temperature at a resolution of 1/1 000 °C - especially if using sensors in air - the measured value display may be unstable. In this case the measured value can be smoothed in the form of a sliding average over a specified time frame. The level of smoothing can be set in the

14.5 Functions of D6 sensors

Normally the functions and ranges of digital D6 sensors can only be configured on a PC connected via an interface cable. However, with this special device - an exception - the measuring ranges and their abbreviations and the atmospheric pressure compensation can also be programmed in the sensor itself; it can subsequently be used in the modified form in other devices too.

However, multi-point calibration and time constant can only be entered via a

So long as the connector configuration is not altered, any number of measuring operations can be saved - either manually or cyclically - all in the same file.

If, however, the connector configuration has been changed since the last measuring operation, a new file will be created; and, if no new file name has been programmed, the index in the file name extension will be incremented automatically by 1, e.g. ´.002´. Similarly, if the file name now entered already exists, a new file will be created with the same file name prefix but with a new index.

Date and time-of-day

15.2 Date and time-of-day

For logging data recordings a real-time clock with date and time-of-day is provided. This real-time clock is buffered by means of the device battery; in the event of battery replacement date and time-of-day are lost. The first line contains the time-of-day on the left and the date on the right; by selecting this function these can be programmed in the format indicated. (see 9.4, 9.5)

Each time the key is pressed again the measured values will be processed in the same way with the associated measuring time.

15.4 Cyclic output / saving of all measuring channels

For cyclic recording and output of measured values the cycle must be programmed accordingly. The measuring operation can be started by pressing

<START> and stopped by pressing <STOP> . Whenever a measuring operation is started the maximum and minimum values from all measuring channels are deleted.

In the course of a measuring operation the external memory must not be unplugged; this would cause all temporarily buffered measured values to be lost.

So long as no measuring operation has been started the

Cycle timer

function displays the cycle previously set. Having selected this function you can specify the cycle directly. (see 9.4, 9.5)

As soon as an operation is started the timer can be seen counting down to the next cycle.

15.5 Memory capacity, memory output, clearing the memory

While measured values are being recorded the Memory free function continuously displays the memory capacity still available. Selecting this function enables two softkeys, one for direct memory output and one for memory clearing.

Function

Memory capacity free e.g.

To output memory content via interface

Memory free

<PMEM>

To clear memory (i.e. reformat the memory card)

<CMEM>

If a memory card is being used the device itself can only read out (in table mode) the measured data contained in the file most recently used.

The most sensible approach is to remove the memory card and copy the files via a USB card reader directly onto a PC. These can then be imported either into MS-Excel or into Win-Control.

During memory output the Output Remaining function continuously updates and displays the amount still to be output.

Memory output, remaining

Output Remaining

15.6 Memory time available

An important parameter for data recording is the memory time available. This depends on the memory still free, cycle and the number of active measuring channels.

Memory time available in days (D) and hours (h) Memory time 24 D 13 h

15.7 Sleep mode

For long-term monitoring involving long measuring cycles the device can also be operated in sleep mode. In energy-saving sleep mode the measuring instrument switches off completely after each measuring channel scan (sensors with their own power supply) and switches on again automatically after the cycle expires ready for the next measuring channel scan. In this way with just one set of batteries or one battery recharge over 15000 measuring channel scans can be performed. For a cycle lasting 10 minutes this represents an available measuring duration of over 100 days.

For data recording in sleep mode the following parameters must be set :

1. Enter a cycle lasting at least two minutes Cycle

Cycle

4. In the measuring menu start measuring operation by pressing

<START>

The device should then display

Sleep On

The device then switches off and the only visible activity is the flashing red

LED ´SLEEP´ at the top of the display. LED ´SLEEP´ (4) flashes

5. The device switches on automatically as per the specified cycle, performs one measuring channel scan, and then switches off again.

6. To quit sleep mode press

15.8 Starting and stopping measuring operations

A measuring operation can be started / stopped not only by pressing the appropriate keys but also automatically by means of start time / end time or a specified measuring duration.

Start date and time-of-day, end date and time-of-day

A measuring series can be started / stopped automatically at specified times.

For this purpose the start date and time-of-day and the end date and time-of-day must be programmed. If no date has been programmed, the measuring operation will be performed every day within the set period.

Or, alternatively, instead of specifying the end time the measuring duration itself can be pro-

16.3 Interface, baud rate, data format

Via the serial interface you can output measured data online or saved measured values to a printer or computer. For connecting to the various interfaces we have a series of data cables available. The data cables should be plugged in at socket A1 (2); in ´Device configuration´ the programmed baud rate then appears.

On leaving our factory the baud rate for all interface modules is programmed to

9600 baud. In order to avoid unnecessary problems when networking several devices together the baud rate should not be altered; rather the computer or printer should be set to match. If this is for some reason not possible you can, in the Baud rate function, choose from the values 1200, 2400, 4800, 9600 baud or 57.6, 115.2 kbaud (taking care not to exceed the maximum baud rate

32 ALMEMO

1036

Interface, baud rate, data format for the interface module). The baud rate setting is saved to the EEPROM on the interface module and thus applies when any other ALMEMO ® device is used.

To set the baud rate, function (see 9.5) Baud rate 9600 baud

Data format: 8 data bits, 1 stop bit, no parity (cannot be changed)

16.4 Device Address and Networking

All ALMEMO ® devices can also be networked together very easily thus enabling the user to centrally acquire and record measured values from several measuring instruments - even if these are located far apart. (see Manual, 5.3)

To communicate with networked devices it is absolutely essential that all the devices concerned should have the same baud rate setting but that each should have its own dedicated address; this ensures that only one device responds per command. Before starting network operation ensure therefore that all the measuring instruments involved are assigned different device addresses. For this purpose use the Device address function. On leaving the factory address 00 is normally set.

To set the device address (see 9.5)

Device address: 00

16.5 Data communications

For data retrieval and programming we provide a comprehensive ALMEMO

® protocol (described in the Manual, chapters 6 and 7).

Since this high-precision instrument exceeds the standard ±16-bit range limits

(65000), certain sensor parameters (e.g. base value, factor, zero-point, gain, limit values, analog scaling) are not available. Measured value correction is performed using just one 24-bit multi-point correction system. Data retrieval should be performed using the table format; this is also supported by the Win-

Control data acquisition program.

To display measured values in list format - together with channel, overflow indication, range, and comments text - a new command is provided in the table format.

17. OPTION FE - FUNCTION EXTENSION

Measuring range ´P314´ (B96) has been extended to:

Measuring range -200.000 to +560.000 °C

Accuracy: ± 0.010 K ± 1 digit (in range -50 to +560°C)

There is also an additional measuring range ´P214´ (B69):

Measuring range -200.00 to +850.00 °C

Accuracy:

± 0.05 K ± 1 digit ( in range -100 to +850°C)

Measured value correction by modifying the coefficients of Pt100 sensors.

When calibrating a Pt100 sensor in a calibration laboratory any deviation detected can be managed by adjusting the sensor on the basis of the four real coefficients in the Van Dusen equation.

The easiest way is to use the ALMEMO ® -Control software package.

This incorporates the following terminal commands :

Determine the four coefficients of a Pt100 sensor using command P27.

Select the input channel E00

Determine the coefficients P27 Pt100 COEFFICIENTS:

00: A = 3.90830E-3

18. Trouble-shooting

18. TROUBLE-SHOOTING

This measuring instrument can be configured and programmed in many different ways. It is suitable for connecting a wide variety of different sensors and peripheral equipment. Given these numerous possibilities the device may in certain circumstances not always behave quite as expected. The cause of such unexpected behavior is only very rarely a device defect; usually the cause is incorrect operation by the user, an invalid setting, or unsuitable cabling. In such event try to pinpoint and clear the problem with the aid of the following tests.

Error

No display, display malfunction, keys do not react.

Remedy Check the power supply; replace the batteries; switch off and then on again; if necessary re-initialize. (see 7.4)

Error

Measured values are incorrect.

Remedy Check the status of the measuring channel, in particular the offset. (REL)

Error

Measured values fluctuate unexpectedly or the system hangs in midoperation.

Remedy Check the cabling for any inadmissible electrical connections; unplug all sensors and replace with hand-held sensors in air or phantoms

(for Pt100 sensors, 100 ohms) and test again; then reconnect the sensors one after the other and test again. If a fault persists for any

Error

one connection, check all wiring; if necessary, insulate the sensor and eliminate interference by using shielded or twisted wiring.

Data transmission via the interface does not function.

Remedy Check the interface module, connections, and settings. Ensure that both devices are set to the same baud rate and transmission mode.

(see 16.4) Test data transmission by means of a terminal.

If the computer is in XOFF status. enter <ctrl Q> for XON.

Check the programming by means of ´

P15´. (see Manual, 6.2.3)

Test the transmit line by entering a smoothing factor using command

´ f1 z10´ and check in ´Sensor programming´. Test the receive line by a memory output in the ´Functions´ menu by pressing <LISTM> and <PRINT> and check the display.

If, after performing the above-listed checks and remedial steps, a device still fails to behave as described in the operating instructions, it must be returned to our factory in Holzkirchen, accompanied by a brief explanatory note, error description, and if available test printouts. With the AMR-Control software you can print out screenshots showing the relevant programming details and save and / or print out a comprehensive ´Function test´ in the device list or terminal mode.
