When a pressure module is connected, the pressure module
icon will appear in the status bar and beep at the same time.
Figure 8.8 shows thepressure measurement connections.
Proceed as follows to measure pressure:
1. If measurement is active, press
once, otherwise
press
twice.
2. Press the navigation keys Up/Down to select the first
item from the pop‐up list, then press Enter or Done to
change the measurement.
3. You can press Unitto pull up the pressure unit list which
issupported by the calibrator.
4. You can press Module to view the pressure module’s
information
5. To improve measurement precision, you can press Zero
to clear the measured value.
8.2.9 Thermocouple Measurement (Temperature)
The calibrator supports thirteen standard thermocouples; thermocouple types are identified bycharacter: S, R, B, K, N,
E, J, T, C, D, G, Land U. Table5‐3 shows the temperature ranges and accuracies of these thermocouples. Thermocouple
measurement accepts two reference junction compensation methods: internal reference mode or external reference
mode. When using the internal reference mode, the calibrator will automatically measure the temperatureof cold
