6. How to Mount
It's possible to install close adherence, but recommended so
that 6.5 mm-more than 7 mm may be opened for thermal
radiation.
It will be 6.5mm between the case body by the 29.5mm space.
.
7. How to Connect to/Disconnect from
DIN Rail
1) How to secure the socket
Engage the hook on the rear upper
side of the socket with the rail with
the slider on the bottom side of the
socket downward, and press the
lower side of the socket in the arrow
direction as shown in the drawing to
secure the socket.
2) How to secure the main unit to
the socket
Position the main unit so that the
characters in the front label can be
read in the appropriate direction,
press the main unit into the socket,
and screw the main unit to secure it.
3) How to disconnect the main unit
from the socket
Loosen the screws that secure the
main unit, and pull the unit out in a
straight line.
4) How to disconnect the socket
Put a flat head screwdriver into
the slider slot of the socket and
pull the lower side of the socket
in the arrow direction ②while
pulling the screwdriver in the
arrow direction ①.

9. How to Adjust Output
We have already performed output adjustment in
accordance with your requests at your order. Therefore, no
output adjustment is required if you operate this product
within your requested specifications. If matching with devices
to be connected or regular calibration is required, follow the
steps below.
For calibration, use signal sources (including a standard
voltage/current generator) and measuring instruments
(including a voltmeter and an ammeter) the tolerances of both
of which are more than 10 times that of this product and wait
for 30 minutes or more after turning on the power.
Output adjustment is performed with the setting switch on
the front side of this product.
*Please don't change a setting condition
(right side) of the selection switch 3 after shipping.
○How to adjust
①Set the selection switch 1 (SW SET) to ON.
This action enables switch operation.
②Set the selection switch 2 (M OUT) to OFF.
③Set the selection switch 4 (ZS SEL) to ZERO.
Use the UP or DOWN switch to adjust the output to 0%
when a 0%-equivalent input is provided.
④Set the selection switch 4 (ZS SEL) to SPAN.
Use the UP or DOWN switch to adjust the output to 100%
when a 100%-equivalent input is provided.

⑤Provide a 0%-equivalent input signal again to make sure
that the output is 0%.
If the output deviates, repeat the steps ③and ④.
⑥Set the selection switch 1 to OFF after completion of
adjustment.
At this moment, the adjusted values are written into the
internal memory and switch operation becomes disabled.
* The adjusted values are written into the internal memory
and turning on or off the power does not clear the values.
The write limit to the internal memory is 1,000 times at
maximum.
* If the power is turned off during adjustment, the adjusted
values are not written into the internal memory.
* approximately ±10% fs.
10.Input-output characteristic
It's an arithmetic as follows as a relation between an input
signal and an output signal.
Output＝｜Input｜
①Input signal
②Output signal
11. Simulated Output Function
This product is equipped with the simulated output function
to conduct tests including connection test.
The simulated output is performed with the setting switch
on the front side of this product. (Refer to the drawing in
Section 9 for the switch position.)
○Simulated output procedure
①Set the selection switch 1 (SW SET) to ON
This action enables switch operation.
②Set the selection switch 2 (M OUT) to ON.
③The simulated output value is set with 3steps that use of the
UP and DOWN switches.
(DOWN) 0% ⇔50% ⇔100% (UP)
④Set the selection switch 1 to OFF after completion of
adjustment.
12. Operation beyond Specifications
1) Excessive input
If an input signal beyond the upper limit is provided, the
output signal increases almost in proportion to the input
until approximately 120% fs of scaling setting. But even if
an excessive input signal is provided more, the output
signal does not increase any more.
2) Insufficient input
The output is described below when an input signal below
the lower limit is provided.
(a) The output signal decreases almost in proportion to the
input until approximately -20% fs of scaling setting.
But even if an insufficient input signal is provided
more, the output signal does not minus polarity.
3) Load beyond specifications
(a) For current output, if the input exceeds the “range of
allowable load resistance”, the output is provided
almost in proportion to the input until the voltage
between the output terminals becomes approximately
15 volts. But if the output becomes larger, the output is
saturated resulting in larger error.
(b) For voltage output, if the input falls below the “range of
allowable load resistance”, the output is saturated
resulting in larger error.
