In measuring mode, press the key for approx. 3 seconds.
If any warning or fault messages exist, the corresponding information or error codes
are displayed (page 30 to page 37).
Press the key successively for the next display.
The peak values and the exposition values TWA
1)
and STEL
1)
are displayed.
If no key is pressed for 10 seconds, the device returns automatically to measuring
mode.
Calling the Info-Off Mode
When the device is in a deactivated state, press the key.
The name of the gas, measuring unit and measuring range limit value are displayed for

Fault messages are displayed. Numerical codes of fault messages: see
page 33.
key
The peak values = the maximum measured values in the case of, e.g., CO,
H
2
S, ... or the minimum measured values in the case of O
2
within the storage
interval are displayed
key
The average values of the exposures based on a shift of, e.g., 8 hours (TWA)
of all the active sensors for the exposure evaluation are displayed
key
The short-term values (STEL) = average values of the concentrations over
the average value duration of all the active sensors for the exposure
evaluation are displayed
key
The device is in measuring mode again
1) Only when activated in the device configuration. Delivery status: not activated.
