*This equipment has burnout protection circuit built-in, which upscale
output signal higher than the 100% when connected thermocouple has
been disconnected.
Therefore, if you turn on the power of this equipment without
connecting thermocouple, output signal will rise to around 120% of
full span.
So please turn off the power when thermocouple is not connected.
*This equipment has cold junction compensation sensor as accessory.
Please use this equipment with the cold junction compensation sensor
attached to the socket.
Body and the cold junction compensation sensor must combine the
same No.
5. ADJUSTMENT
Since this equipment has been properly calibrated at the time of shipping,
each trimmer of ZERO and SPAN does not require adjustment as long as
the equipment is operated according to the manufacturing specifications. If
matching with connected equipment or routine calibration is required,
observe the following procedures.
This calibration shall be made 30 minutes after the power supply is turned
ON, using a signal source, and measuring instruments, whose accuracies
are 10 times or higher than that of this equipment. The ZERO and SPAN
adjustment ranges are both about 10% fs. Multi-turn trimmers are installed
for performing these adjustments.
1) ZERO adjustment: Apply a minimum value within the input range to the
input terminals, and turn the zero-trimmer until the
output signal reaches the minimum value within the
output range.
2) SPAN adjustment: Apply a maximum value within the input range to
the input terminals, and turn the span-trimmer until
the output signal reaches the maximum value within
the output range.

Operation Against Conditions out of Range
1
)
Excessively large input
In the case of the input signal exceeding the upper limit of the input
range, the output signal increases increased nearly proportional to
the input up to approx. 120%fs.
2) Excessively small input
If the input signal is lower than the lower limit of the input range,
the output signal reduces nearly proportional to the input down to
approx. -20%fs.
3) Load out of range
①
In the case of current output, if the “allowable load resistance
range” is exceeded, the output obtained will be roughly
proportional to the input over the range to where the voltage
between the output terminals becomes about 15 V. However, if
the input exceeds this range, the output will saturate and the
error will increase.
②
In the case of voltage output, if the output is reduced below the
“allowable load resistance range”, the output will saturate and
the error will increase.
7. INSTALATION DIMENSIONS
When mounting the product on a wall, refer to the installation dimension
diagram.
The diagram below shows the minimum mounting clearance between
adjacent units.
8. Mounting and Removing to/from the DIN Rail
1) How to fix the socket
Hold the product with the slider at
the bottom of the socket facing
downward, engage the tab at the top
of the rear surface of the socket with
the rail, and then push in the bottom
of the socket in the direction of the
arrow to fix the product in place.

）
How to fix the main body to the
socket
Hold the main unit in the direction
such that the text on the label can be
read correctly, insert it perfectly
straight, and then tighten the screws
on the front of the main unit. Be
careful not to tighten the screws too
hard.
3
）
How to remove the main body
from the socket
Slacken the screws on the front of
the main unit, and withdraw the
main unit perfectly straight.
4
）
How to remove the socket
Insert a screwdriver in the slider
groove of the socket. While pulling
the screwdriver in the direction of
the arrow as shown in Figure
①
,
draw the lower part of the socket
forward
②
until it is removed.
Note)
Note that if you continue to slacken the screws on the front panel of the
main unit, they will drop out of the main unit.
