ELAN (RS485), PROFIBUS-PA/DP as option
Automatic calibration (adjustment) of all channels with ambient air (in case
oxygen is present as measured component) or nitrogen (depending on
measured component),
adjustable cycle time from 1 ... 24 hours. If 0 hours is entered, the cycle is
deactivated.
AUTOCAL cycle must be activated for certified emission measurements
Add-on electronics, with 8 additional digital inputs and 8 additional relay
outputs, for e.g. triggering of automatic calibration, PROFIBUS PA/DP
