5.1 Set Date and Time
Press F1- Set date / time in the service menu.
The date can be edited by pressing F1 and the time by pressing F2.
5.2 Device Data
In this screen information for the service engineer is displayed (operational hours, lamp
voltage, heating coil cycles, software version)
5.3 Show Flow
In this screen the flow for sampling and the flow during thermal desorption of the mercury from
the GoldTrap (heating flow) can be read.
a) Heating flow: press F1. Stop flow reading by pressing ESC.
b) Sampling flow: press F2. Stop flow reading by pressing ESC.
The allowed range for heating flow is 8.5 – 11.5 l/h, for sampling flow 38 – 42 l/h. An error
message will appear if the flow is out of these ranges. The value displayed on the right bottom is
the pump voltage. The allowed range for this voltage is 6 – 11 V. During measurement mode an
error message will appear if the voltage is out of this range.
5.4 Purge Repetitions (for Automatic Calibration Option only)
The parameter set for purge repetitions is only available when the automatic calibration mode has
been activated. It determines how often the automatic syringe is purged with calibration gas for
conditioning.
