6.6 Info Menu
Sub menu ALARM
An alarm protocol starts as soon as the internal alarm threshold is exceeded. This threshold is sensor
specific. Find a listing in capter 12.2.
The memory can store only 3 alarm events. These parameters are stored: alarm start, concentration
maximum, alarm end. The alarm events are not listed chronologically. If there was no alarm yet, the
display shows zeros only.
In order to achieve a meaningful protocol, the clock must be set correctly (see chapter 6.2).
Sub menu DOSIS
The total exposure is the product of concentration multiplied by exposure time ppm * h. Exposure by
calibration is neglected.
The maximum exposure reading depends on the measuring range. It is either 9.99 or 99.9 or 999
ppm * h. If it is too high to be displayed, the display shows FF PPMH.
Oxygen sensors do not have this feature.
The total exposure provides information about the exposure history of the sensor, but it is not a direct
quality criterion.
Sub menu SENSOR
FJ is an internal factor, created during calibration. You cannot use this to calculate the sensor signal.
JUSTDATE is the most recent calibration date.
SN is the sensor serial number.
BB is the best before date of the sensor in week / year.
