Moisture Probes
The moisture probe is the part of the system that comes in contact with the process, and is usually installed in a sample system. The
Series 35 IS uses any M Series probe to measure dew point temperature in °C or °F. A sensor assembly is secured to the probe mount and protected with a sintered stainless steel shield
(see Figure 1-2 below). Other types of shields are available.
Figure 1-2: The M Series Probe
The Sample System
The sample system conditions or controls a sample stream to the specifications of the measurement probe. Typically, the sample system is kept very simple, with as few components as possible located upstream of the measurement probe. The sample system may include a filter to remove particulates from the sample stream and/or a pressure regulator to reduce or control the pressure of the sample stream. In general, stainless steel is the preferred material for all the sample system’s wetted parts.
If it was specified at the time of purchase, your Series 35 IS will include a self-contained sample system.

March 2008
Choosing a Measurement Site
You should have discussed environmental factors with a GE
Sensing applications engineer or field sales person before you receive your Series 35 IS. The equipment should be suited to both the application and the measurement site.
Read the following guidelines to verify that you have selected the best measurement site.
•
Choose a measurement site for the probe and sample system as close to the process line as possible. Avoid long lengths of connecting tubing. If long distances are unavoidable, a fastsampling bypass loop is recommended.
•
Do not install any other components, such as filters, upstream of the probe or sample system unless instructed to do so by GE
Sensing. Many common components, such as filters and pressure regulators, are not suitable for sample systems. These components contain wetted parts that may absorb or release materials (e.g., moisture) into the sample stream or allow ambient contamination to enter the sample stream. In general, use stainless-steel for all parts in contact with the sample.
•
Observe all normal safety precautions. Use the probes within their maximum pressure and temperature ratings.
•
Do not expose the electronics unit to high temperatures, strong electrical transients, mechanical vibrations, corrosive atmospheres, or any other conditions that could damage or interfere with the Series 35 IS operation. See Chapter 5,
Specifications, for limits.
•
If you are using an external sample system, you should observe the proper cable restrictions for the probes. The M
Series probes require specially shielded cable. For units with separate sample systems, you can locate the M Series probes up to 100 meters (330 feet) from the Series 35 IS.
•
Protect the probe cables from excessive strain (bending,
2-2
pulling, twisting, etc.). In addition, do not subject the cables to temperatures above 65°C (149°F) or below –50°C (–58°F).
Installing the Series 35 IS
March 2008
Moisture Probe Considerations
The M Series probes consist of an aluminum oxide sensor located on a connector and covered by a protective stainless-steel shield.
The probe sensor materials and housing maximize durability and minimize water absorbing surfaces in the vicinity of the aluminum oxide surface. A sintered stainless-steel shield protects the sensor from high flow rates and particulate matter (other shields are available). Do not remove the shield except upon advice from GE Sensing.
The sensor design permits the device to withstand normal shock and vibration. Be sure to avoid touching the active sensor surface or allowing it to come into direct contact with foreign objects.
Such contact may adversely affect performance.
Observing these precautions should ensure a long and useful probe life. GE Sensing recommends that you check probe calibration routinely, at one-year intervals, or as recommended by the applications engineers for your particular application.
Because the probe measures water vapor pressure in its immediate vicinity, proximity to the system walls, materials of construction, and other environmental factors can influence readings. You can operate the sensor under vacuum or pressure and under dynamic or static conditions. Observe the following environmental precautions.
1. Temperature Range: the standard probe is operable from
–110°C to +70°C (–166°F to +158°F).
2. Moisture Condensation: be sure the temperature is at least
10°C higher than the dew/frost point temperature. If this condition is not maintained, moisture condensation could occur on the sensor or in the sample system and cause reading errors. If reading errors occur, refer to “Aluminum Oxide
Probe Maintenance” in Appendix A.

Moisture Probe Considerations (cont.)
3. Static or Dynamic Use: the sensor performs equally well in still air or where considerable flow occurs. Its small size makes it ideal for measuring moisture conditions within completely sealed containers or dry boxes. It also performs well under gas flow linear velocities as high as 10,000 cm/sec, and liquid flow linear velocities to 10 cm/sec. Refer to Tables
A-2 and A-3 in Appendix A for maximum gas and liquid flow rates.
4. Pressure: the moisture probe always senses the existing water vapor pressure regardless of the total ambient pressure. The moisture sensor measures water vapor under vacuum or high pressure conditions from as little as a few microns Hg to as high as 5000 psi total pressure.
5. Long-Term Storage & Operational Stability: continuous abrupt humidity changes do not affect the sensor, and exposure to saturation conditions does not damage the sensor, even when stored.
6. Freedom from Interference: the presence of a wide variety of gases or organic liquids does not affect the sensor. Also, large concentrations of hydrocarbon gases, Freon®, carbon dioxide, carbon monoxide, and hydrogen do not affect sensor water vapor indications. The sensor functions properly in a multitude of gaseous or non-conductive liquid environments.
7. Corrosive Materials: avoid all materials that are corrosive or otherwise damaging to aluminum or aluminum oxide. These include strongly acidic or basic materials and primary amines.

Sample System Guidelines
A sample system, although not mandatory, is highly recommended for moisture measurement. The purpose of a sample system is to condition or control a sample stream to within the specifications of the probe. The application requirements determine the design of the sample system. GE
Sensing applications engineers can make recommendations based on the following general guidelines:
•
Typically, keep the sample system simple. Include as few components as possible and locate all or most of the components downstream of the measurement probe. A simple sample system consists of an explosion-proof housing with a sample cell, a filter, and inlet and outlet needle valves.
•
Do not use any material for sample system components that can affect measurements. A sample system may include a filter to remove particulates from the sample stream and/or a pressure regulator to reduce or control the pressure of the stream. However, most common filters and pressure regulators are not suitable for sample systems because their wetted parts may absorb or release components (such as moisture) into the sample stream. They may also allow ambient contamination to enter the sample stream. In general, use stainless-steel for all wetted parts.
Note: The actual sample system design depends on the
application requirements.

March 2008
Mounting an External Sample System
Note: If you have a Series 35 IS with a self-contained sample
system, disregard this section and proceed to The Self-
Contained Sample System on page 2-7.
The sample system is usually fastened to a metal plate that has four mounting holes. GE Sensing can provide the sample system in an enclosure, if requested. Sample system outline and dimension drawings are included in your shipment, if you ordered them.
Use the following steps to mount the external sample system and connect it to the process:
1. Fasten the sample system plate or enclosure to a solid stable surface with bolts and washers in each of its four corners.
2. Connect the process supply and return lines to the sample system inlet and outlet using the required stainless-steel fittings and tubing.
Caution!
Do not start a flow through the system until the probe has been properly installed.
Note: For common applications, GE Sensing can provide a
standard sample system. If applicable, additional instructions on how to start up and shut down the sample system may be included.

The Self-Contained Sample System
The Portable Series 35 IS can include a self-contained sample system as shown in Appendix B. This sample system is constructed with 1/4" Swagelok® inlet and outlet compression fittings and 1/4" stainless-steel tubing.
The sample system also includes inlet and outlet needle valves and a 7-micron sintered stainless-steel filter with a replaceable element. All wetted parts are Series 300 stainless steel, Viton®, or Teflon®. The maximum allowable pressure for the sample
system is 4500 psig. See Figure 2-1 below.

Making External Probe Connections (cont.)
Note: The connector on the probe cable must be rotated until it
aligns with the pins in the probe connector, before the cable may be properly inserted into the probe and secured.
3. Connect the other end of the probe cable to the terminal block
on the Series 35 IS side panel (see Table 2-1 below and
IMPORTANT:
To maintain good contact at each terminal block and to avoid damaging the pins on the connector, pull the connector straight off (not at an angle), make cable connections while the connector is away from the unit, and push the connector straight on (not at an angle) when the wiring is complete.
Caution!
The M Series probe may not be capable of withstanding the 500 V insulation test required by clause 5.7 of EN50 020 when installed in the process media. This must be taken into account in any installation in which it is used.

Using Modified or Non-GE Sensing Cables
In some installations, it may be desirable to use a pre-existing moisture cable or to modify the standard GE Sensing moisture cable. If this approach is taken, it is essential that the following precautions be observed. Furthermore, after connecting the moisture probe, a calibration adjustment must be performed to compensate for any electrical offsets introduced by the nonstandard cable.
Caution!
GE Sensing cannot guarantee operation of the Series 35 IS to the specified accuracy unless a standard GE Sensing hygrometer cable is used.
1. Use cable that matches the electrical characteristics of GE
Sensing cable (contact the factory for specific information on cable characteristics).
2. If possible, avoid all splices. Splices will impair the performance of the instrument. When possible, instead of splicing, coil the excess cable.
3. If you must splice cables, be sure the splice introduces minimum resistive leakage or capacitive coupling between conductors.
4. Carry the shield through any splice. A common mistake is to not connect the shields over the splice. If you are modifying a
GE Sensing cable, the shield will not be accessible without cutting back the cable insulation. Also, do not ground the shield at both ends. The shield should be grounded only at the
hygrometer end, as described in Table 2-1 on page 2-12.
2-14 Installing the Series 35 IS
March 2008
Performing a Calibration Adjustment
After completing the installation of a modified or non-standard moisture cable, it is necessary to perform a calibration adjustment on the Series 35 IS. This procedure will adjust the electronics to compensate for any error or offset introduced by splices or long cable lengths. It is also recommended that a calibration be performed after the installation of a new GE Sensing cable, to verify the accuracy of the unit.
Use the following steps to perform a calibration adjustment:
1. Power up the Series 35 IS.
2. To check the new cable, set up the screen to display “MH”.
See Chapter 3, Operating the Series 35 IS, for instructions on how to navigate through the user program.
3. Note the high, low and zero reference values that are recorded on the sticker located on the inside of the Series 35 IS chassis.
4. Disconnect the cable from the probe only (leave the cable connected to the Series 35 IS), and verify that the displayed
MH value equals the zero reference value within ±0.0003 MH.
If this reading is within specifications, no further testing is necessary.
5. If the zero reference value reading above was out of range, the low reference value must be adjusted. For readings more than
0.0003 below the previously recorded zero reference value, add the difference to the low reference value. For readings more than 0.0003 above the previously recorded zero reference value, subtract the difference from the low reference value. Record the final corrected low reference value.
6. Reprogram the Series 35 Is with the new, corrected low reference value. See Entering High and Low Reference Values in Chapter 3.
7. Make sure the cable is still disconnected from the probe but is connected to the Series 35 IS.

March 2008
Performing a Calibration Adjustment (cont.)
8. Recheck the zero reference reading and verify that it is now within ±0.0003 MH of the previously recorded value.
9. Fill out a new reference sticker with the final low reference value and/or record the information on the Data Information
Sheet in Appendix D. Make sure the following information is included:
•
HIGH REF = Original Value
•
LOW REF = New Corrected Value
•
ZERO REF = Original Recorded Value
10.Reconnect the cable to the probe.
Note: If the cable is changed in any way, repeat the above
procedure for maximum accuracy of the unit.

Starting Up and Shutting Down the Sample System
If your Series 35 IS has a self-contained sample system, use this section to properly start up the sample system before you begin taking measurements, and to shut down the sample system when you have finished taking measurements.
Note: If you are using an external sample system, refer to the
separate manual supplied with your order.
Starting Up the Sample System
In order to operate the self-contained sample system correctly, first determine if you need to make measurements at atmospheric pressure or at process pressure. After determining the pressure, use the appropriate section that follows to start up and shut down the sample system.
Note: The maximum allowable pressure for the self-contained
sample system for the Series 35 IS is 4500 psig.
At Atmospheric Pressure:
1. Begin with the Series 35 IS inlet and outlet valves in the closed position, then open the outlet valve completely.
2. Open the inlet valve slightly to allow only a small amount of flow from the process.
At Process Pressure:
1. Begin with the Series 35 IS inlet and outlet valves in the closed position, then slowly open the inlet valve fully.
2. Open the outlet valve slightly to allow only a small amount of flow.

Shutting Down the Sample System
At Atmospheric or Process Pressure:
1. Close the inlet valve completely.
2. Wait for the flow from the outlet valve to stop.
3. Close the outlet valve to keep the probe sensor from being affected by ambient moisture.
Powering Up the Series 35 IS
To turn on the Series 35 IS, press the POWER switch (located on the left side of the front panel) to the ON position. (If the battery is depleted, see Chapter 4, Troubleshooting, to recharge the battery.)

March 2008
Entering an Interval for Automatic Calibration
(cont.)
After you confirm the Autocal interval and return to the main menu, the Series 35 IS immediately performs an Autocal. The next time Autocal occurs depends on the length of the time interval setting.
The Series 35 IS determines the times of subsequent Autocals by establishing a fixed schedule, beginning at midnight, using the specified interval. For example, if you enter a 90-minute time interval, Autocal occurs 16 times per day
(1 day = 1440 minutes ÷ 90 minutes = 16).
The following fixed schedule applies:
1. 1:30 a.m.
2. 3:00 a.m.
3. 4:30 a.m.
4. 6:00 a.m.
5. 7:30 a.m.
9. 1:30 p.m.
10. 3:00 p.m.
11. 4:30 p.m.
12. 6:00 p.m.
13. 7:30 p.m.
6. 9:00 a.m.
7. 10:30 a.m.
14. 9:00 p.m.
15. 10:30 p.m.
8. 12:00 p.m.(noon) 16. 12:00 a.m.(midnight)
If you enter a time interval not evenly divisible into 1440 minutes, the Series 35 IS rounds up to the next acceptable interval. For example, if you set the 90-minute Autocal interval at
6:10 p.m., the next Autocal occurs at 7:30 p.m. (excluding the
Autocal performed when you exit the Autocal menu).

Setting Up Computer-Enhanced Response
Note: This option may not be installed on your Series 35 IS.
Using a dynamic moisture calibration technique, Computer-
Enhanced Response extrapolates the moisture level to the end point, when making measurements in abrupt “dry down” conditions. Response time depends on the relative change in dew point. For example, the Series 35 IS can respond in three to five minutes to reflect a change from ambient moisture to trace levels.
The accuracy of Computer-Enhanced Response equals ±2°C of the sensor reading, assuming an equilibrium with the gas. To ensure accuracy, your application should:
•
Have a reasonably constant flow rate and final dew point.
•
Maintain a minimum flow rate of one standard cubic foot per hour (SCFH).
•
Operate at atmospheric pressure (0 psig)
•
The actual moisture content must be above –85°C frost point and must be stable.
You can enable or disable the Computer-Enhanced Response feature. If the feature is not available, the display reads Option

Setting Up the Data Logger
The Series 35 IS optional data logging feature enables you to internally view and store measurement data. The main menu displays the LOGGER prompt only if this option is available on your unit.
Data is logged at user-selected time intervals and stored in the unit’s FRAM. Up to three different parameters may be logged at any one time.
Note: Because the Series 35 IS contains a fixed amount of
memory, the more parameters you select and the more frequently you log data, the shorter the total available logging time.
The Series 35 IS assigns a record and a header to all logged data.
The record consists of logged measurement values. The header includes the time the log started, the constant pressure value, the log time intervals, and the selected measurement modes. By assigning each log a header, the Series 35 IS distinguishes one log from another.
The Series 35 IS can store more than one log. Each time the log setting is changed, the Series 35 IS queries if you want to overwrite or append to the existing log(s). If overwrite mode is chosen, the Series 35 IS writes over the logs currently stored in memory. If append mode is chosen, the Series 35 IS adds new log data to the end of the previously stored log data. In either case, the Series 35 IS continues logging measurement data until it runs out of memory.
Note: Before beginning setup of the data logger, check to make
sure that the clock is set to the correct time and date. See
“Setting the Clock Values” on page 3-28 for the
procedure to follow.

Common Problems
Incorrect Series 35 IS measurement readings may indicate a
measurement and ways that you can rectify the problems.
Troubleshooting and Maintenance 4-1
Symptom
Table 4-1: Troubleshooting Guide
Possible Cause System Response Action
Accuracy of moisture sensor is questioned
Insufficient time for system to equilibrate
Dew point at sampling point is different than the dew point of the main stream
Probe reads too wet during dry down conditions, or too dry in wet up conditions
Change the flow rate. A change in dew point indicates the sample system is not at equilibrium, or there is a leak. Allow sufficient time for sample system to equilibrate and moisture reading to become steady. Check for leaks.
Probe reads too wet or too dry
Probe reads too wet or too dry
Readings may be correct if the sampling point and main stream do not run under the same process conditions. The different process conditions cause the readings to vary. Refer to
Appendix A for more information. If sampling point and main stream conditions are the same, check sample system pipes and any pipe between the sample system and main stream for leaks.
Also, check sample system for adsorbing water surfaces, such as rubber or plastic tubing, paper-type filters, or condensed water traps. Remove or replace contaminating parts with stainless steel parts.
Clean the sensor and the sensor shield as described in Appendix
A. Then reinstall the sensor.

Calibration Error Processing
A Calibration Error indicates a failure during the measurement of the internal moisture references. During Autocal, internal references are read repeatedly and the Series 35 IS compares measured values to a table of acceptable factory calibration values. The system calculates and corrects any deviation from the factory values. If a reference falls outside the acceptable range, a
CAL ERROR
message appears.
If you attempt to display data after the system experiences a calibration error, the display reads “ CAL ERROR DP/°C .”
Note: The units displayed, (e.g., °C) depends on the previously
selected measurement units.
Troubleshooting and Maintenance 4-7
March 2008
Recharging and Replacing the Battery
Portable battery-powered units, with and without internal sample systems, require a battery charger that accepts either 110 VAC or
220 VAC input, and outputs 12 volts DC at a maximum current of
500 mA.
A fully charged Series 35 IS battery pack provides continuous operation for between 12 hours (with the backlight on) and 120 hours (with the backlight off). When the battery charge is low
(usually below 5.85 volts), the screen blinks and displays the
“Supply Low” prompt. This display remains on the screen for approximately one (1) hour before the Series 35 IS shuts down the electronics.
4-8 Troubleshooting and Maintenance

4. Disconnect the five (5) cables from the J2, J3, J4, J5, and J6 connectors on the back (non-component side) of the main printed circuit board.
IMPORTANT:
To maintain good contact at each terminal block and to avoid damaging the pins on a connector, pull the connector straight off (not at an angle).
5. If your Series 35 IS includes a self-contained sample system, you must disconnect the moisture probe cable from the probe at this time (refer to Installing a Probe into a Sample System in Chapter 2).
6. Remove any external connections to the Series 35 IS. These may include: the battery charger, an RS232 interface cable and/or a moisture probe cable from an external sample system.
7. Remove the main printed circuit board from inside the cover by unscrewing the four screws that fasten the circuit board to its mounting bracket.
8. Turn the circuit board over to access the EPROM on the component side of the circuit board.
Note: To replace the circuit board, refer to Replacing the Circuit

Replacing the EPROM
Caution!
EPROMs can be damaged by static electricity. Be sure to discharge any static electricity from your body before handling the EPROM.
Replace the EPROM by carefully completing the following steps in the order presented.
1. Refer to Figure 4-3 on page 4-18 to locate the EPROM
(labeled U18) on the component side of the main printed circuit board.
2. Use a chip puller to remove the EPROM. If you do not have a chip puller, use a small screwdriver to carefully wedge the chip out of its mounting. Be sure none of the EPROM legs breaks off in the socket.
3. Insert the new EPROM into the socket labeled U18, making sure the notch on the EPROM aligns with the notch on the
socket. See Figure 4-3 on page 4-18.
4. If all the EPROM legs do not align with the corresponding holes in the socket, gently remove the EPROM and place it on its side (where the legs are located) on a flat surface. Then, gently roll the EPROM toward the legs to bend the row of legs slightly inward.
Caution!
The EPROM legs are very delicate and may snap off if they are bent too far or too many times.
5. Repeat step 4 for the legs on the opposite side of the EPROM.
Then, insert the EPROM back into its socket, making sure that the notch on the EPROM aligns with the notch on the socket.

6. Gently press the EPROM into place until it is fully seated in the socket, making sure not to bend or break any of the legs.
Repeat steps 4 and 5 if necessary.
Caution!
Do not force the EPROM into the socket. If the EPROM does not seat easily, check for bent legs or legs that do not properly align with the corresponding holes in the socket.
4-18 Troubleshooting and Maintenance
March 2008
Replacing the Circuit Board
1. Turn the circuit board over so that the component side (the side with the EPROM) of the board faces the inside of the
Series 35 IS cover, and position the circuit board on the mounting bracket in the cover.
Note: When orienting the circuit board within the electronics
unit cover, make certain that the RS232 connector, battery charger jack and external probe cable connector are properly inserted into the cutouts in the side panel of the cover.
2. Install and tighten the four (4) previously removed bracket screws and washers in the corners of the circuit board.
3. If your unit includes a self-contained sample system, reconnect the moisture probe cable to the probe at this time
(see Chapter 2, Installing a Probe into a Sample System).
4. Reconnect the five (5) cables to the J2, J3, J4, J5, and J6 connectors on the back (non-component side) of the circuit board. The cables that connect to J2 and J5 are polarized and can only be inserted in the correct orientation. However, the three (3) ribbon cables could be rotated 180° from the proper alignment. Therefore, make sure that the previously applied pin 1 marking on each ribbon cable aligns with the pin 1 label on the circuit board at the J3, J4 and J6 connectors.
IMPORTANT:
To maintain good contact at each terminal block and to avoid damaging the pins on a connector, push the connector straight on (not at an angle).
5. Replace the Series 35 IS cover by attaching it to the unit from front to back. Tighten the two quarter-turn screws on the back of the unit.
6. Reconnect any external cables such as the battery charger, an
RS232 interface cable and/or the moisture probe cable from an external sample system.
Troubleshooting and Maintenance 4-19
March 2008
Replacing and Recalibrating the Moisture
Probe
For maximum accuracy you should send probes back to the factory for recalibration every six months to one year, depending on the application. Under severe conditions you should send the probes back for recalibration more frequently. Contact a GE
Sensing applications engineer for the recommended calibration frequency for your application.
When you receive a new or recalibrated probe, make sure to install and connect it as described in Chapter 2, Installing a Probe
into a Sample System. Once you have installed and connected the probes, enter the calibration data as described in Chapter 3,
Entering Calibration Data.
Note: An individualized Calibration Data Sheet, containing the
corresponding probe serial number, accompanies each probe.
