8.2.4 Calibration
menu
With the calibration menu, the control unit can be calibrated for all channels during
initial installation and, if necessary, during maintenance and repair work on the
control unit or the gas detection system. For instructions on how to calibrate the
transmitter; see the instructions for use for the remote sensor transmitter.
Carry out zero-point calibration:
1. Select
Zero-point calibration
for the respective channel.
2. Select
Channel calibration
.
●
If the success message is displayed, exit the menu to save the calibration.
●
If an error message appears, observe the information relating to fault
elimination.
Creating calibration gas
1. Use a calibration adapter to create calibration gas at the transmitter. Create
calibration gas with a concentration between 40 and 90 % of measuring range
and with the flow rate specified in the instructions for use for the transmitter.
2. Let the measured value on the control unit display stabilise for 2 to 3 minutes.
3. Select the calibration menu of the respective channel.
4. Select
Span calibration
>
Gas concentration
.
5. Enter the concentration of the calibration gas and select
Calibrate channel
.
●
If the success message is displayed, exit the menu to save the calibration.
●
If an error message appears, observe the information relating to fault
elimination.
Control of the transmitter output signal
1. Set the signal output of the transmitter to a value between 10 mA and 20 mA.
2. Select the calibration menu of the respective channel.
3. Select
Span calibration
>
Signal mA
.
4. Enter the transmitter signal and select
Calibrate channel
.
●
If the success message is displayed, exit the menu to save the calibration.
●
If an error message appears, observe the information relating to fault
elimination.

.
Zero-point cali-
bration
Before calibrating the channel, the transmitter must be cali-
brated to ensure that the output signal of the transmitter is 4 mA
with a zero gas value.
Span calibra-
tion
Calibrate the span either by creating calibration gas at the
remote sensor transmitter or by influencing the output signal of
the transmitter using the transmitter control to simulate a gas
signal.
