5. Scale Adjustment
When you perform a trace printing (dot printing) position adjustment only, refer to “5-2. Zero and Span Adjustment for
Trace Printing”.
5-1. Scale Check
The check is performed on a channel to channel basis. Even if all channels use the same measuring range, an error in
measured value may occur between channels.
The rated accuracy varies between digital display and
analog indication.
Use a tester with the accuracy equal to or higher than the
specified rated accuracy.
1. Preparation
(1) Turn OFF the power switch and perform the wiring depending on the input signal (see figure below).
Connect to the input terminal of the check target channel.
(2) Attach the terminal cover.
(3) Turn ON the power switch and change to [Continuous indication mode]. For details of [Continuous indication
mode], refer to “9. Continuous Indication Mode” in instruction manual “General”.
(4) Display the check target channel.
(5) Energize the unit for at least 30 minutes (an hour or more is ideal) and then perform checking.
Digital display: Temperature input ······· ±0.2%
DC voltage input ········ ±0.1%
Analog indication: ±0.5% of scale range
The accuracy of the unit is ±0.1%. Therefore, you
need to use a tester having higher degree of
accuracy to perform proper checking. Also, attention
should be paid to the thermocouple error.
Note that a tester requires time to ensure its stability
and accuracy.
Tester accuracy
Note 1
Make sure that the reference junction temperature is
0°C. When using an electronic reference junction
temperature compensator, read its instruction
manual. Also, the compensation accuracy should be
checked.
Reference junction compensator
Note 2

- 13 -
2. How to check
(1) Set a tester (standard DC voltage generator or precision variable resistor) to an input value equivalent to the
check target value.
(2) At this time, read the digital display and check if the error is within the specified accuracy range.
(3) Next, change to the check target channel and check it likewise.
(4) Check also the analog indication/dot printing position.
* The accuracy of the unit is rated at an ambient temperature of 23°C ±2°C. Ensure safety of the surrounding
environment.
* When you changed the wiring with the terminal cover removed, energize the unit for at least 30 minutes
after attaching the terminal cover and then perform checking.

one time). Align the position with the zero
line of the chart.
3) Press the key to register the zero
position in the memory.
(3) Adjusting span position of chart
1) Press the key when you complete
the zero adjustment. The display shows
and dotting is performed at
the initial position (left side of span line)
while feeding the chart.

position right/left slightly (about 0.05mm at
one time). Align the position with the span
line of the chart.
3) Press the key to register the span
position in the memory.
(4) How to end
Press the key and select ,
and then press the key.
The mode changes to [Operation mode] when the
key is pressed on the passcode entry
window ( ).

(1) Preparation
1) Connect a tester (standard DC voltage generator or precision variable resistor) to an adjustment target
channel number.
2) Pressing the key changes adjustment item. Select .
(2) Select channel number
Pressing the / key advances/reverses channel number. Select a desired channel number.
(3) Zero adjustment
Obtain zero correction data
Apply an input equivalent to zero value
(minimum value of measuring range).
→
The span adjustment display appears
several seconds after pressing the
key.
The display shows a channel number and
zero value (minimum value).
When the minimum value input and the
correction data registration to the memory
are completed, the display changes to the
span adjustment display.

Obtain span correction data
Apply an input equivalent to span value
(maximum value of measuring range).
→
The zero adjustment display appears several
seconds after pressing the key.
The display shows a channel number and
span value (maximum value).
When the maximum value input and the
correction data registration to the memory
are completed, the display changes to the
zero adjustment display.
