You can exit navigation mode by "travelling too
far": Press when Time is selected – or press
when Ready Beep is selected. Pressing twice
gives the same result - you choose to set a
parameter, and accept the old, unchanged value.
If you have changed a parameter, there is no
"escape button”. However, apart from the GM-
voltage, everything can be reset by turning off and
on again. The GM voltage should be set at 500 V
when using Frederick's GM tubes.
Battery Saver Function
The unit turns off automatically after an hour - but
only if it is inactive.
Communication with a computer
Communication requires a cable with built-in
adapter (512565). The adapter has an associated
driver that must be installed on your computer.
Find information about downloading this driver on
the packaging for the adapter or on our website.
The adapter is recognized as a virtual serial port.
Communication parameters can be set in
Windows’ Control Panel.
Communication protocol
Commands to the unit consist of one letter,
eventually followed by a number.
The possible responses from the device depend on
the command.
C: Read Company Information
Returns the string "(c) Copyright 2010 A/S S.
Frederiksen"
D: Read register values
Returns the current values of secondary and
primary data registers
E: Send results or not
When used alone, it returns status. When used
with parameter 0-1, the status will change
according to the following:
'e0' counts not automatically sent
'e1' counts sent automatically when each
count period has finished
F: Counting time
When used alone, it returns the actual counting
time in seconds. When used with parameter 0-5,
counting period is changed according to the
parameter:
'f0' Infinitely
'f1' 1s
'f2' 10s
'f3' 60s
'f4' 100s
'f5' 300s
Other counting periods are invalid. Display icons
are updated accordingly.
J: GM voltage
When used alone, it returns the current GM
voltage in volts. When used with parameter 400-
700, the GM voltage is modified according to the
parameter. Example:
'j520' GM voltage set to 520V
O: Single / Repeat Mode
When used alone, it returns status. When used
with parameter 0-1, mode is changed accordingly:
'o0' Single
'o1' Repeat
