8. Press O to activate the calibrator output.
Four softkey labels appear on the Control Display. Press the OUTPUT softkey to toggle
the rtd selection, displaying the rtd setup menu and four softkey positions.
The temperature you entered above will be cleared to 0
change between tc (thermocouple) and rtd (resistance temperature
detector), or change the type of rtd. If this occurs, select OUTPUT rtd, the
desired rtd TYPE, and then reenter the temperature following steps 4 to 8.
•
Out @ NORMAL displays the location of the output terminals (always NORMAL)
for rtd connections.
•
TYPE (RTD Type) selects the rtd curve from a list.
•
OUTPUT (Temperature Output Device) Selects the temperature device:
thermocouple (tc) or resistance temperature detector (rtd). Select rtd.
•
COMP (Compensation) Applies 4-wire compensation, 2-wire compensation or turns
compensation off. Compensation refers to methods of connecting the Calibrator to
the UUT to cancel out test lead resistance. See "Four-Wire versus Two-wire
Connections" earlier in this chapter for more information. For the 3-lead connection
(Figure 4-9) select COMP off.
How to Measure Thermocouple Temperatures
Complete the following procedure to measure the output of a thermocouple connected to
the TC input. If you make an entry error, press G to clear the display, then reenter.
1. Press R to clear any output from the Calibrator.
2. Connect the thermocouple to the front panel TC connector.
Use thermocouple wire and miniconnectors that match the type of
thermocouple. For example, type K wire and type K miniconnectors.
