PRODUCT OVERVIEW
beam path. Reference filters are then moved into position to control the check point. The
spectral properties of the device are checked using a test gas cell. If a check cycle reveals
that the system is not functioning in accordance with the operation specifications, the
GM35 measuring system outputs appropriate error or warning messages.
Triggering options
1 Di 1 (falling edge): The check cycle can also be suppressed with this function.
2 Time interval, adjustable via the menu of the EvU.
Sequence
1 Check cycle is started.
2 Internal reference measurement is executed. Signal: Relay 3 (function check)
3 The zero point and check point are output on the EvU display and the assigned analog
outputs for 90 seconds each.Relay 3 remains active.
Fig. 5: Determining the check point
Observe the following for connecting to an emission computer: Measure the
time from the start to the output to compensate differences in the device
settings.
