Before entering the workplace

WARNING
Incorrect calibration can lead to incorrect measurement results, which may
result in serious damage to health. Before performing safety measurements,
check the calibration with a functional test and adjust as necessary. If national
regulations exist, the functional test must be performed in accordance with
these regulations.
1. Turn on the sensor unit.
2. Follow the instructions in the mobile app.
3. Wait for the start-up phase, heat-up phase and temperature stabilisation.
4. Ensure that neither of the gas inlet openings or the gas outlet opening on
the sensor unit is covered or contaminated.
5. Ensure that the water and dust filter is fitted and not covered or
contaminated.

During operation

– In operation, the mobile app is used to control the sensor unit, display
measured values and issue error messages, warnings and alarms.
– The status LED on the sensor unit continues to display whether it is
connected to the mobile app (continuously lit
– Navigate through the various views.
– In the Measure view, read off the concentration values of the Seeker
measuring mode and start an analysis program of the Analysis measuring
mode.
– View saved measurements in the Records view.
4.6.1

Measurements in Seeker measuring mode

– Seeker measuring mode is used for continuous measurement of the total
concentration of multiple volatile organic compounds in the ambient air at
the workplace and in explosion-hazard areas.
– Read off the direct display of the Seeker measuring mode in the Measure
view.
– Individual response factors are not taken into account; instead a simplified
response of isobutylene is assumed (CAS number 115-11-7).
4.6.2
– Analysis measuring mode is used for measuring the concentration of
individual hazardous substances in the ambient air at the workplace and in
explosion-hazard areas.
– Start analysis programs for preset target compounds in the Measure view.
– Read off the selective result when the measurement period elapses.
– Individual response factors of the target compounds are taken into account.
4.7
Visual alarms can be displayed in the mobile app and acoustic alarms as well
as vibration alarms can be issued by the control unit. Alarms are dependent on
substance-specific limit values that first need to be configured by the user. For
more information, see the technical manual.
4.8
– The sensor unit can be placed in standby mode in the mobile app to shorten
). the time until operational readiness following a break between
measurements.
– Pumps are turned off in standby mode, whereas the detectors remain
turned on, the operating temperature is maintained and the sensor unit
remains connected to the mobile app.
– Standby mode must be exited in the mobile app to restart the sensor unit.
– No measurements can be carried out in standby mode.
– In standby mode, the status LED flashes (
Due to component wear and tear, during extended breaks between
measurements it is better to turn off the sensor unit instead of putting it into
standby mode. For this reason, standby mode should only be used when a
reduced time to operational readiness is required.
