3) Handling
・When removing or mounting the main body from/to the socket, be
sure to turn OFF the power supply and the input signal in advance to
prevent any problems.
4) Installation
・This equipment is designed for indoor use.
・Please install the main body in a location where the ambient
temperature is within -5 to 55°C.
・Please install the main body in a location where relative humidity is
less than 90%RH (no freezing or condensation).
・When the equipment is to be installed in a location where there is
excessive dust or metal particles, house it in a dust-proof cabinet,
which has a heat radiation function.
・Avoid exposing the equipment to vibration and impact, which may
cause malfunction.
・Please do not block ventilation openings of the main body.
5) Wiring
・Be sure to keep the wiring of the power line, input signal line and
output signal line away from any noise source, relay driving line and
high-frequency line.
・Avoid clamping these lines together with a noise-superimposed line
or putting them together in the same duct.
6) Others
・This equipment can be operated as soon as the power supply is
turned ON. However, for optimum performance, allow 30 minutes of
energizing time.
・This product is precision equipment. It is therefore recommended
that you periodically calibrate it by performing ZERO and SPAN
adjustments once a year.

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 (such as standard voltage, current generator),
and measuring instruments (voltmeter, ammeter), 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.
6. OperationAgainst Conditions out of Range
1) Excessively large input
When a signal exceeding the upper limit of the input range is input,
the output signal is increased nearly proportional to the input up to
approx. 120%fs. If a greater input signal is input beyond that, the
output signal won’t be increased beyond approx. 120%fs.
2) Excessively small input
If a signal lower than the lower limit of the input range is input, the
output operation is as follows.
①In the case of a current output, the output signal flows to the
negative side as well. However, the negative current carrying
capacity is only about 5 mA, so do not pass negative current.
②With the voltage output, the output signal is reduced nearly
proportional to the input down to -120%fs.
3) Load out of range
①In 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.
②In 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.

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.
2）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 ②until 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.
