Figure 2 PMA 45K1
An inspection window in the housing 1 of the analyzer makes it possible to control the measuring val-
ue display 2, the LEDs 6 (status alarm) and 7 (heating regulation) as well as the span LEDs 11 and
12.
All operating devices are accessible from outside and guarantee a simple and user-friendly handling
for calibration as well as for the measuring range switch over.
The operating devices are:
• Adjustment of measuring range final value 3,
• Measuring range selector switch 4 and
• Adjustment zero point 5.
The oxygen indication of the PMA 45K1 is made by a digital display instrument 2. Here, the oxygen
value is shown within a range of 0-100.00 vol% with a definition of 0.01 vol%.
The measuring range switch over is made via the selector switch 4. The selected measuring range is
indicated via a respective LED 11 on the front plate of the PMA 45K1.
The selection of the measuring range can also be effected externally. The LED 12 on the front plate of
the analyzer in connection with the respective measuring range LED is signalizing the external meas-
uring range control.
The function of the analyzer heating is indicated with LED 7. When switching on the instrument, this
LED is permanently illuminated in yellow. When the LED is flashing, the operating temperature is
achieved, when the LED is out, the temperature is exceeded. For all other status alarms as described
below, the LED 6 changes from green to read.
