1.2 Source Function
The source function generates DC voltage, DC current, resistance, voltage corresponding to the
electromotive force of thermocouples, voltage corresponding to the resistance of RTDs (pseudo-
resistance), and pulse signals.
It can be used simultaneously with measurement functions other than temperature measurement
using thermocouples.
DC Voltage
This function generates the following DC voltages.

Notes
100 mV
±110.000 mV
Maximum output current: 10 mA
1-5 V
0.0000 V to +6.0000 V
Maximum output current: 10 mA
Can be used as calibration signals for 1, 2, 3, 4, 5 V.
(1-5 V√)
0.0000 V to +6.0000 V
Maximum output current: 10 mA
Values for square root operation
5 V
±6.0000 V
Maximum output current: 10 mA
30 V
±33.000 V
Maximum output current: 1 mA
1-5 V Range
The interval between 0% and 100% is equally divided by four, and the 0%, 25%, 50%, 75%,
and 100% values are output.
With the default settings, you can change the output between 1 V, 2 V, 3 V, 4 V, and 5 V in 1
V steps by pressing the UP or DOWN key. This is convenient when calibrating the five points
from 1 to 5 V.
Square Root Output Function
(1-5 V√)
Values corresponding to the square root of 0%, 25%, 50%, 75% and 100% values are
generated. You can change the output using the UP or DOWN key. This can be used as
calibration signals for the square root output of differential pressure transmitters.
