Technical data

If the transmitter is set to 100%, but the fit sensor had already been used in another unit which was
set to 50 % or 75 %, the display will also read CHEC SCAL .
Notes:
After the sensor was put into operation for the very first time, or when the sensor has been replaced,
the transmitter may indicate an overrange resp. underrange (____ resp.
----
). In this case the
automatic zeropoint adjustment (ZERO) has to be activated to correct the zeropoint.
Should SCAL ERR. occur (resettable), the sensor must be re-calibrated (SPAN) or, if necessary, the
detection range of the sensor must be adapted to the hardware in the service menu.
Allow a warm-up time of at least 30 minutes before you check the zeropoint. Once the warm-up is
completed, the display should have stabilized to read 0. Otherwise activate the (automatic) zeropoint
adjustment (Adjustment see page 11).
!
Once the sensor was replaced (no matter which service and adjustment interval is
being considered), you have to effect a complete service and adjustment according to
DIN EN 50073 para. 6.4.3.
Check and adjustment of zeropoint and sensitivity is to be done as described (pages
11-14).
Transmission Characteristics
Depending on the type of gas the transmitter is subject to different transmission characteristics.
Different gases may show different response times. The transmission signal is always proportional to
the gas concentration
