RANGE CONFIGURATION
CAUTION !
•With the current input configuration (SW1-1 ON), DO NOT apply voltage input.
•DO NOT apply voltage exceeding the maximum value of the selected range.
•Applying voltage input greater than the maximum value of the selected range may cause failure of the unit. Check the
setting before applying the input signal.
■GENERAL PROCEDURE
First select a coarse range using the internal DIP switches (SW1 and SW2) according to Tables 2 through 5 below.
Then apply simulated 0% and 100% inputs and fine-tune the output range to 4 mA and 20 mA using the front zero and span
adjustments.
■INPUT TYPE & RANGE Table 1

DC Current -30 to +30 mA DC Min. 16 µA, Max. 60 mA -100 to +80%
DC Voltage -100 to +100 V DC *1Min. 4 mV, Max. 100 V of the selected range *2
*1. Refer to Table 3 for the maximum value of selectable ranges.
*2. Max. voltage across the input terminals: 70 V for conform with EU Directive; 60 V for UL approval.

■SELECTING DIP SW (coarse adjustment)
INPUT TYPE
Choose Current or Voltage according to Table 2.
INPUT RANGE
Choose the desired range matching the maximum value
and the span according to Table 3.
•For a current input, convert the range to a voltage with
the following equation:
Table 2 ■= ON
INPUT TYPE SW1

Current ■
Voltage
Voltage = (100% Current – 0% Current) ×250 Ω
•When the 0% and 100% values have the same polarity, select the absolute greater value as Span.
•When the 0% and 100% values have opposite polarity, select the absolute difference of the two values (100% – 0%) as Span.
•If the Span value is available in two range selections, select the smaller range. (e.g. Set to the 1 V range for 0 – 1 V, though
the maximum value 1 V can be selectable both in 2 V and 1 V range.)
•The minimum span and offset requirements in the table must be met when choosing the desired range.

CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) DIP SW setting: Check that the switches are set to ap-
propriate positions.
3) Input: Check that the input voltage is within 0 – 100% of
full-scale.
4) Output: Check that the load is within the permissible
limit including wiring resistance.
Load Resistance (Ω) = Supply Voltage (V) – 12 (V)
0.02 (A)
(including leadwire resistance)
5) When you check the output signal, connect an ammeter
of which the internal resistance is of 10 Ω max. to the
monitor terminals.
ADJUSTMENT PROCEDURE
This unit is calibrated at the factory to meet the ordered
specifications, therefore you usually do not need any cali-
bration.
For matching the signal to a receiving instrument or in case
of regular calibration, adjust the output as explained in the
following.
■HOW TO CALIBRATE THE OUTPUT SIGNAL
Use a signal source and measuring instruments of sufficient
accuracy level. Turn the power supply on and warm up for
more than 10 minutes.
1) ZERO: Apply 0% input and adjust output to 0%.
2) SPAN: Apply 100% input and adjust output to 100%.
3) Check ZERO adjustment again with 0% input.
4) When ZERO value is changed, repeat the above proce-
dure 1) – 3).
MAINTENANCE
Regular calibration procedure is explained below:
■CALIBRATION
Warm up the unit for at least 10 minutes. Apply 0%, 25%,
50%, 75% and 100% input signal. Check that the output
signal for the respective input signal remains within accu-
racy described in the data sheet. When the output is out of
tolerance, recalibrate the unit according to the “ADJUST-
MENT PROCEDURE” explained earlier.
