4.5 Source Thermocouple (TC) Signals
4.5.1 Source Thermocouple (TC) Signals
Generate voltages (mV) corresponding to the following thermocouples.
Set the temperature with (°C). This enables calibration of a thermometer.
Thermocouple (TC) types: K, E, J, T, N, L, U, R, S, B
(For the temperature range, refer to the specifications.)
1
Connect the terminals.
2
Use the FUNCTION key on the SOURCE side to align
the
source mark with TC. (Thermocouple selection)
3
Use the RANGE key to select a thermocouple type.
4
Use the ▲ ▼ output value setting keys to set each digit output value.
5
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.
6
Press the SOURCE ON/OFF key to start generation.
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) → source value (mV) → temperature monitor (°C)
(The display returns to the setting value (°C)
if no key is pressed for 10 seconds.)
Temperature Scale Standard Setting
The temperature scale standard (ITS-90/IPTS-68) can be selected in
setting mode.
Refer to "4.6 Generating Resistance Temperature Detector (RTD) Signals" and
"7. Setting Mode."
• 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 how to use a cold junction compensator, refer to “Appendix 1.”
