●
Remove the device from the Bump Test
Station.
— If the concentration values have now fal-
len under the A1 alarm setpoints, the de-
vice returns to the measuring mode.
— If during the function test no alarm occurs
and the current measured values do not
reach the set target concentration, the er-
ror alarm is activated to indicate failure.
— The fault message »
« appears and
»
« is displayed instead of the
measured value on the faulty measuring
channel.
●
In this case, repeat the function test with
gas or calibrate the device, page 35.
The function test with gas can also be carried
out manually, refer to page 29 and page 30.
