pares and outputs the measured values and performs control and monitoring func‐
tions. The EvU can be located in the vicinity of the sender/receiver unit. It can also be
located up to about 1000 meters from the sampling point, e.g. installed in the switch
center or monitoring center, and performs the following functions:
Output of measured values, computed data and operating states
Communication with the peripheral equipment
Output of error messages and other status signals
Access during service (diagnosis)

4 Important information on GPP measuring probes
CAUTION
Observe the following information during commissioning of the GPP measuring probe
to avoid damage to the measuring system and to achieve stable measurements.
Check the filter surface visually for damage.
Warm the probe up for about 30 minutes beforehand so that the temperature of
the window and triple reflector is sufficient to prevent condensation on the optical
surfaces.
Gas can escape at the measuring probe during overpressure processes when the
1/4" plug is open or loose. Air is suctioned into the measuring probe during low-
pressure processes. The measured value in the chamber then drops depending on
the low-pressure in the process, possibly down to zero.
Do not damage the filter when inserting the probe in the flange.
