By pressing any key, the model CPH7650 portable pressure calibrator will be switched
on. The calibrator requires a warm-up for a few minutes (max. 5 minutes) to reach its
specified accuracy. Large changes in ambient temperature may make a longer warm-up
period necessary. The pressure display of the calibrator should be zeroed before starting
the pressure calibration.
Instrument features
The instrument features 3 operating modes: MEASURING / CALIBRATION / SWITCH
TEST, which offer the user maximum convenience according to its application. For
supplying the test items and to read their measuring signals, there are electrical inputs
and outputs available.
In the MEASURING (with test item) and CALIBRATION operating modes, the measured
values of both the reference pressure sensor and the test item, as well as their deviation,
are displayed in both current pressure units and in %. In this way the operator is
immediately informed online whether the test item meets the class accuracy or not.
The difference between these two modes is that the calibration data in CALIBRATION
mode are stored internally and can later be transferred onto printable certificates through
software (WIKA-Cal).
With respect to the transfer of data to a PC, the model CPH7650 pressure calibrator has a
USB interface, selectable via menu.
SETUP menu
Using the SETUP key, one can access the SETUP menu, where the required operating
mode (MEASURING / CALIBRATION / SWITCH TEST) can be selected and configured,
a stored function can be recalled or a general instrument setting (such as the menu
language) can be changed.
