Remarks:
191: Tedlar-Bag-Mode is only used for instruments optionally equipped for this method to
determine Hg in natural gas or other gas samples.
222: Zero offset- for correction of the analytical zero value, this value is subtracted from the
measurement peaks.
Temp offset- for correction of the offset of an automatic or manual calibration device.
Heating Flow: allows to set heating flow, shall not be changed from standard setting except
for special applications (high measuring range).
Flow Regulate: For service purpose only, shall not be changed from standard setting.
If “Heating flow regulate= ON“ then the pump is controlled by the mass flow meter signal
within +/- 2 l/h of the set value.
If “Heating flow regulate= OFF“, then the pump is fed with a constant voltage (7.5 V) and the
flow may vary within a range of +/- 3 l/h.
If the Flow is out of range, a Repeat Zero will be performed up to 10 times, after this the system
will be halted and an error message will be displayed.
333: Shows the peak during System Evaluation when on; a horizontal line is displayed when off.
753: For calibration service of flow meter only!
777: Only on if an Automatic Calibration Unit is installed. Has to be on if an automatic
calibration should be performed.
881: For service only!
987: For service only!; allows to actuate valves and status contacts.
999: Mode of automatic calibration can be selected: multiple point calibration or one point span
calibration.
