2
To measure temperature, connect the analog output thermometer to the instrument.
Before connecting the thermometer, read "Operating Precautions" (p.6) carefully.
When using a thermometer that generates 4 to 20 mA output, connect a shunt resistor of
about 50
Ω
between the positive and negative terminals and convert the output to a voltage
prior to input. With a 50
Ω
resistor connected, the reference voltage ( V
1
, V
2
) settings are
0.20 V ( V
1
) and 1.00 V ( V
2
).
Connecting an Analog Output Thermometer
1
Confirm that the instrument's Main
power switch (rear panel) is OFF(
).
2
Connect the thermometer's analog output
connector to the TEMP.ANALOG INPUT ter-
minal block on the rear panel, using a
cable.
3
Configure temperature measurement.
