play is illuminated every time you hit
a key. Each key stands for one func-
tion, thus providing error-free
handling without tedious instruc-
tion lessons.
Service mode
The service mode allows quickadjustments of the Polytector II.Alarm thresholds, pump modes,
calibration, zero point adjustment
and many other special functions
are easily configured by means ofthe menu driven service program.A safety code protects the Polytec-
tor II from incidental changing or
manipulation of important para-
meters.
Indication of gas concentration
All measured gas concentrations aresimultaneously shown in the biggraphic display. The digit heightchanges automatically for best pos-
sible reading, depending on the
amount of information to be indica-ted. The zoom function portraysthe gas concentration in big figures
(17 mm) over the entire display. The
additional display illumination com-
pletes the perfect readout.
One button for „ON“ and increasedsafety by two buttons for „OFF“ -that’s all you need for normal ope-
ration. Only 4 buttons control addi-
tional functions: Indication of gas,
zoom display, pump, battery check,special EX measurement are availa-ble for the user at any time. The dis-
