10.4.2 Service Menu
The Service menu functions support
• input of test values (output current, count rates) to simulate instrument functions
• check of outputs and inputs
• adjustment of analog outputs and inputs
• adjustment of Pt 100 input
• plateau recoding of detector
• manual setting of high voltage for test purposes.
The individual functions are described below.
Test calculate:
Any pulse rate within the calibration range can be entered. The count rate supplied by
the detector will then be ignored.
The respective output current is calculated from the count rate and the density value.
Output current and the respective density or concentration value are displayed as a re-
sult of the defaulted pulse rate.
The product temperature supplied via Pt 100 or as current signal is taken into
account when calculating the measured value. If necessary, temperature com-
pensation for the test is disabled. To do this, select “Density without TC”.
After completion of the test, reset the test count rate to “0”!
I/O Test Output Current:
To use this function, the measurement must not be in the RUN mode.
To test the connected instruments, you can set any output current between 0 and
22 mA.
View input current:
Shows the current measured at the current input.
Relay 1/2/3:
The relays can be switched to test the signal circuits (ON = relay energized).
Input 1/2/3:
Shows if the inputs are open or closed (OFF = input open).
HV Adjustment:
Set HV detector
With the standard setting “0” the detector works with automatic high voltage control. If
you enter a high voltage value for special tests, the high voltage control is disabled. The
entered value is used as fixed high voltage. In this case, the info HV-Test is displayed in
the measurement menu or the live display (instead of HV auto)
Set this value to “0” again when you exit the Service menu. Otherwise, the
measurement device will not work correctly.
Status request
