- Terminal ground, enables internally LO output terminal grounding
Coefficients of „PT User“ scale. RTD calculation formula is
, where T is temperature in °C and R0 is
nominal resistance of temperature sensor at 0 °C.
In TEMPERATURE TC function calibrator simulates thermocouple temperature sensor by sourcing
such DC voltage to the output terminals which corresponds set temperature and selected type of sensor.
Following screen appears after the function selection:
To simulate a TC temperature sensor:
1. Connect thermometer input to HI – LO output terminals.
2. Select TC Type sensor, one of following R, S, B, J, T, E, K, N, M, C, D, G2
3. Select requested temperature standard PTS-68 or ITS-90
4. Select Manual RJ mode and enter cold junction temperature into RJ field. With MER option
and Adapter 91 connected as in picture below you can also use Auto compensation mode:
5. Enter requested temperature value into main field on the display to simulate temperature sensor.
6. Push the OPER key to activate output. Real DC voltage level is displayed in yellow information
line in upper part of the display. If the line is hidden, push any key for value setting cursor key,
rotary button or SELECT arrow key.
