Measuring Temperature

Using Thermocouples

The calibrator supports eleven standard thermocouples, each identified with an alpha character: C, L, U, E, N, J, K, T, B, R, or S. Table 5 summarizes the ranges and characteristics of the supported thermocouples.

To measure temperature using a thermocouple, proceed as follows:

1.Attach the thermocouple leads to the appropriate TC miniplug, then to the TC jack as shown in Figure 12. One pin is wider than the other. Do not try to force a miniplug in the wrong polarization.

NOTE

If the calibrator and the thermocouple plug are at different temperatures, wait one minute or more for the connector temperature to stabilize after you plug the connector into the TC jack.

2. If necessary, press Mfor MEASURE mode.

3.Press tso that the display prompting you to select the TC type shows.

4.Select the desired TC type using the uor d followed by e.

5.If necessary, you can change between °C or °F Temperature Units in smode as follows:

a.Press s

b.Press the Next Page softkey twice.

c.Use the uand d keys to move the cursor to the parameter you which to change, then press e or the Choices softkey to choose a setting for that parameter.

d.Press uor dto move the cursor to the desired setting.

e.Press eto go back to the s display.

f.Press the Done softkey or sto exit s mode.

6.If necessary, you can change between ITS-90or IPTS-68 Temperature Scale in smode. The procedure is the same as steps a through f above.
