3.2.4 Zeroing

In the gauge pressure mode, when the device is vented, it can be zeroed if there is deviation in zero point, so as to

eliminate the zero drift, supported zero range is 1% FS.

3.2.5 Statistics

See paragraph 3.1.10.

3.3 Temperature measurement

The calibrator supports thermocouple (TC) and thermal resistance (RTD) temperature measurement.

3.3.1 Thermocouple measurement

The connection of thermocouple measurement is shown in the Figure 8 Thermocouple measurement. Then click the

features switching menu of channel 1 and select the TC measurement.
