4.3.3 Units of pressure
This feature allows the operator to select the units used for displaying pressures. Certain
measurement ranges cannot be displayed meaningfully in some units, in which case the units in
question are not available. The following units may be selected:
hPa
mbar
Torr
mmHg
mmH2O
inH2O
kPa
Pa
4.3.4 Unit 2 (optional)
As an option, the KAL200 can now be fitted with an input port for voltage measurements and an
input port for current measurements. If this option is active, it can be used to display the
measurement, which is presented in the second line. For example, if the user selects V as the
unit, the voltage measured at the voltage input port will be displayed in the second line. This
also applies for the pressure and target value features. The KAL200 is therefore capable of
measuring the voltage and output current of a sensor. These values can also be readout using
the interface and, if necessary, processed directly in a form. The corresponding ports are
located on the rear of the instrument.
4.3.5 Zeroing
By default the instrument resets the zero point approximately 6 minutes after it is initially
switched on and then automatically every 30 minutes or after a major temperature change.
Zeroing always results in changes in volume and thus to pressure. This can disrupt certain
measurement sequences. Zeroing is automatically suppressed when the instrument is in test
mode. The instrument can also be zeroed by pressing and holding (approx. 0.5 s) any of the
operating mode keys (target value, pressure, test).
4.3.6 Language
This feature allows the operator to select the language used. The languages available are
German, English, French, Italian and Spanish.
