Mounting and Installation
Putting in operation
After switching on the device, a self-test and tempering period follows. This procedure takes 30 - 50 minutes,depending on the ambient conditions.
During this time the output analogue voltage differs from the actual measured value.
Switching point setting
A switching point between 10 % and 95 % of the measuring range can be selected using the SET potentiometer. The 10 % value is added to the fresh
air limit of 400 ppm for CO . With other measurands, the corresponding lower limit is used directly as a basis. A potential-free changeover contact

is available as a switch output. The assignment of the switch output to measurand is done via DIP switch (DIP 7 and DIP 8).
Offset
Each measuring channel has a separate offset potentiometer for subsequent adjustment of the measurement. The adjusting range is ± 10 % of the
measuring range.
Display
In the first line, the measurements with the corresponding units
( CO in ppm, VOC in %, temperature in °C, relative humidity in % r.H.)

are displayed in a cyclical series.
In the second line, the switching status of the relay is shown on the left as a circuit
