- Pressure
The Multimeter can only be used with the specified
pressure sensor accessories (see Table above).
- Calibration of pressure sensor:
The pressure sensor must be connected to the in-
strument during the calibration procedure. Press the
Select button once, and the message:
ProbCal
will
be shown in the display. Press Select again, and the
message:
1.000 cF
will be shown. The scale factor
for the pressure sensor can now be selected using
the Adjust buttons. The new selection is confirmed
by pressing the Select button, and the display
shows the message:
0.0 Ofs
. It is now possible to
adjust the zero offset for the pressure sensor by
means of the Adjust buttons. Confirm the selection
by pressing Select. The instrument will then change
to the measurement mode and show the current
pressure reading. Note that the calibration factors
are stated on a label on each pressure sensor.
- Menu:
This option is intended for use with special facilities,
e.g. for connection to a PC. In the current version of
the Multimeter this option has not been implemen-
ted.
