4.6 Source Resistance Temperature Detector
(RTD) Signals
Resistance Temperature Detector: Select from PT100 and JPT100.
Temperature scale standard: Select from ITS-90 and IPTS-68.
(The default setting: ITS-90)
The temperature scale standard can be set in setting mode.
1 Connect the terminals.
2 Use the FUNCTION key on the SOURCE side to align
the source mark with RTD.
(Resistance temperature detector selection)
3 Use the RANGE key to select PT100 or JPT100.
4 Use the ▲ ▼ output value setting keys to set each digit output value.
Each ▲ ▼ key corresponds to a digit of the setting value.
Each time a key is pressed the value is incremented or decremented by
one count. If you attempt to increment or decrement
the value 9 or 0, the digit moves up or down one place.
A value continues to change when you hold down the key.
Press the CLEAR key to restore the setting to its initial value (zero).
5 Use the + ← → - key to select a polarity if the polarity needs
to be changed. (No sign appears for +.)
6 Press the SOURCE ON/OFF key to start generation.
(SOURCE OFF changes to ON.)
7 Press the SOURCE ON/OFF key again to turn off the output.
(OFF lights and the output terminals are open-circuited.)
Toggling Display
Press the ENTER key to toggle the display as shown below.
Setting value (°C) → resistance value corresponding to temperature (Ω) →
temperature monitor (°C)
(The display returns to the setting value (°C) if no key is pressed
for 10 seconds.)
• When using the divided output (n/m) function,
refer to "4.8 Divided Output (n/m) Function."
• When using a sweep output function,
refer to "4.9 Sweep Output Functions."
• When using the temperature monitor function,
refer to "4.10 Temperature Monitor Function."
Tip
For details on the procedures for resistance generation and three-wire connection
output method, refer to “4.4 Generating Resistance (Ω) Signals.”
