Cautions
Cautions during temperature measurement and high sensitivity measurement
(1) Change in temperature difference between inside and outside of the U-841 will
cause zero drift. Pay attention to the following points when mounting the recorder.
1) Do not use an air conditioner or the U-841 in a location that is free from radical
changes of temperature.
(Since environmental temperature changes considerably when the air conditioner
is activated or stopped, the U-841 is affected by thermoelectromotive force.)
2) Avoid using the U-841 in a windy location or where it is exposed to direct sunlight. Use the U-841 in the place where temperature change between day and
night is small.
3) To maintain temperature of the terminal section at a stabilized level, be sure to
use the attached terminal cover. Do not clog the ventilation hole in the case
during use.
(2) If the metal tip or wire materials other than copper are used for wiring of the input
cable, a thermoelectromotive force of several lV may be generated.
Therefore, be sure to use copper wire in high-sensitivity measurement. Make the
input cable as short as possible.

5. DESCRIPTION OF OPERATION
5. DESCRIPTION OF OPERATION
5.1 Waveform Recording
This section explains operations until the input signal is recorded by the pen.
Input amplifier
Input unit
Maximum voltage applied to the input terminal is ± 30 V when the
input range is a thermocouple or at a high sensitivity of 30 V. When
the range is 1 V or more, the unit will not be damaged even if voltages
up to 200 V are applied. Voltage widths that can be recorded are less
than the maximum voltage and are determined by the range.
Range
When the range is determined by the bias, the bias become the range.
The range and bias that are set at the right end and left end are determined indirectly. In this case, the level with a larger absolute value is
converted into the range. For example, if a setting is made with the range of 9 V to 10 V, 10 V is the standard range, the recording is 1 V
(10 V - 9 V = 1 V) and the measurement span is 10 V. Accordingly,
the measurement is carried out in a span from 0 to 10 V, and only the
portion of 9 V to 10 V is recorded. In this case, resolution of the record is approximately 1/10 of a recording from 0 V to 1 V.
Filter
10 Hz digital filter is supplied. When using 50/60 Hz, noise levels of
-50 dB cab be removed. (Normal mode) It is also possible to set a filter of approximately 1 Hz separately. This filter is the primary filter.
A/D converter
The input signal amplified by the input amplifier is converted into a
digital value by A/D conversion. For the A/D conversion, all channels
are divided into two blocks with each block converted alternately in 2
ms intervals. Therefore, you can get data A/D conversion every 4 ms
from each channel.
Data processing
Data from the A/D converter is processed at every 4 ms for each channel irregardless of the thermocouple and voltage. For the thermocouple,
temperature offset (linearize) is carried out at every 4 ms.
Cold contact point compensation is also carried out.
Cold contact point compensation, CJC
Temperature at the input terminal is measured with one temperature
sensor for one unit. During measurement by the thermocouple, compensation processing is carried out with this input terminal temperature.
Temperature at the cold contact point is measured every 256 ms and
updated. When measuring the temperature, be sure to mount the input
cover.
- 56 -
5. DESCRIPTION OF OPERATION
Pen operation
Synchronizer
SYNC
The pen is driven to its position following the input signal that is processed. If a square wave is input simultaneously to all pens, the motors
for all pens will consume the maximum voltage. So, to limit maximum
power consumption, the pen speed is made slow for square waves input
simultaneously to all pens.
The synchronizer memorizes the data with a resolution of time axis equal to 0.05 m (1/20 mm). Synchronized with the chart paper feed, it
outputs the data of the proper channel at proper timing in order to make
the time axis in the record agreed.
Input value
Synchronizer compares the data with the stored data every 4 ms and stores the maximum and minimum values between 0.05 mm feed and the
mode. The time to send the 0.05 mm is different depending on the chart
speed. The comparison is carried out at a fixed timing of 4 ms.
Accordingly, phenomenon that occurs for short times is stored irregardless of the chart speed.
Mode
For the mode value, the existence of a maximum value and minimum
value and values generated later are stored.

5.2 Setting Function
Same range
COPY MODE
For setting multiple numbers of input units in the same condition and for
setting partial numbers in different conditions, you can copy the setting of
only one channel.
Press the INPUT key to call the screen to set the input condition. With
the SELECT key, move the cursor to the location where the copy source
channel is displayed. Condition of copy source channel will be copied.
After placing the cursor at the channel display, press the ENTRY key.
ß will display at the outside of the column for copy source channel.
Determine the copy source in this way. Using the SELECT key, move
the cursor to the channel display you want to set the same condition as
the copy source and press the ENTRY key. When the same condition of
the channel to copy as the copy source displays, you can copy it. By changing the copy destination one by one, you can copy as many times as
you want. Moving the cursor to a location other than channel display terminates copy mode. For multiple copy sources, escape from the copy
mode and enter the copy mode again. Setting for the copy source is again
possible.
Even if a portion of the condition are different, settings are easily done
by copying and changing the conditions.
Same scaling
When many inputs units are the same scaling, copy mode can be used in
the scaling setting screen. The same method for the same range is available.
Built-in clock
For the built-in clock, set the time as 00 seconds the instant the ENTRY
key is pressed. Error of this setting is within one second. Because the
built-in clock is baked up by the battery, it will continue operation approximately one month even if the power is disconnected. If some errors
in the setting are detected, move the cursor to the location of the detected
value, and correct the setting.
Example of error: Month of 18 or February 31st.

5. DESCRIPTION OF OPERATION
5.3 Display Function
Waveform display sampling
Waveform displays using data sampled at every 64 ms.
Because approximately 15.6 samplings are carried out in one second,
the display is around -3dB for an input signal of approximately 3 Hz.
Since this sampling is not related to the chart speed, waveform up to
approximately 3 Hz can be displayed at any time.
However, if the input signal changes extremely when chart speed is slow,
waveform is written over.
Digital display sampling
Digital display sampling is not fixed. The current value appears one by
one. If there are only a few display channels, the sampling cycle will
become short. If the input signal exceeds 1 Hz, it may be synchronized
with the sampling. When it is synchronized, digital value becomes a constant although the waveform display and pen record will change. By
changing the number of the displayed channels, the synchronization of
digital display stops. In any case, even if the digital display is done against for an input signal exceeding 1 Hz, the value read will be not important.

How to determine the measurement value
(1) Determine the SAVE CH(address 10 and address 11)of the setting information.
For example, when address 10 is 15H and address 11 is 0, the channels become 1 CH,
3 CH, 5 CH, so the measurement date are written in the repetition of 1, 3, 5, 1, 3, 5, 1,
3, 5, --- CH.
(2)Determine the position of decimal point and their units of the measurement date
corresponding to the SAVE channels obtained in (1).
For example, when SAVE CH are 1, 3, and 5 CHs.
CH
1 CH
3 CH
5 CH
Position of decimal point
address 610 -- 1
address 612 -- 0
address 614 -- 2
UNIT
address 626 -- 0
address 628 -- 1
address 630 -- 2
In the above case, the measurement date for each channel becomes as follows.
1 CH: xxx.x
3 CH: xxxx
5 CH: xx.xx
μV
mV
V
(3)ASCII conversion software
ASCII conversion can be carried out with the above procedure of (1) and (2).
It is, however, easier with our ASCII conversion software "KAMIT".

Error information
Occurrence of an error is displayed as follows.
(1) R/W ERROR!
This error occurs when a CFCARD is not loaded, a CFCARD is writeprotected,
a CFCARD is damaged.
(2) SAME FILE NAME!
This error is displayed when the same file name as that of the save time is specified.
(3) FILE NAME ERROR!
When the character which I cannot use is included it is displayed.

*1 range
Select range from Table 2 in accordance with setting values.
1) When input setting is "SPAN": Range of setting value is either of SPAN-L or
SPAN-R, larger one.
Example:
If setting is SPAN-L: 1.2 V and SPAN-R: 1 V, range 1 to 1.2 V is recorded.
As the setting value range is 1.2 V, measurement calculation range is 2.048 V, and accuracy is calculated as:
±(0.05% x 0.2 V + 0.03% x 2.048 V + 1 lV) = ± 0.714 mV
2) When input setting is "RANGE":
(1) Zero point setting: 0 to 100%
From Table 2, decide the setting value range and measurement accuracy calculation
range.
Example:
If setting range is 1.5 mV and zero point is set to 20%, the range between -0.7 mV to
1.2 mV is recorded. As the setting value range is 1.5 mV, measurement calculation is
2 mV, and accuracy can be calculated as follows:
±(0.05% x 1.5 mV + 0.03% x 2 mV + 1 lV) = ± 2.35 lV
(2) Zero point is - side and +100% or more
Numerical value of the setting value plus zero point position becomes the setting
value range in Table 2.
Example:
If setting range is 1.5 mV and zero point is set +200%, the range between 3 mV to
4.5 mV is recorded. As the setting value range is 1.5 mV x 200% + 1.5 mV = 4.5 mV,
measurement calculation is 8 mV, and accuracy can be calculated as follows:
±(0.05% x 4.5 mV + 0.03% x 8 mV + 1 lV) = ± 5.65 lV
