Switches and Connections
RUN/SET Switch
This switch is located in the top right hand corner of the front panel.
When the instrument is in the RUN mode, it will display the measured signal, the value of which will
depend whether the instrument is set to display RATE or COUNT. Momentarily pressing this switch
once puts the instrument into the SET mode and activates the DP, 0–9 ; and the
+
(polarity) switches.
To return to the RUN mode, simply momentarily press this switch once again.
FUNCTION (FUNC) Switch
This is located directly below the RUN/SET switch and is used when it is required to observe or set
the programmable parameters. When in the SET mode, momentarily pressing the FUNC switch
steps through the parameters in the following sequence see Programming the Instrument on page 8:
If the instrument is in the RUN mode, a single depression of the FUNC switch will toggle the display
between showing the accumulated TOTAL value, or the current RATE value (unless there is no input
signal when displaying RATE , in which case the display will show NO SIG ).
DP (Decimal Point) Switch
This is located under the FUNC switch and is used to set the position of the decimal point as
required. A single depression of the switch will move the decimal point one decade. Holding the
switch depressed will cause the point to move in decade steps from right to left at a pre-determined
rate. This switch is only active when setting either the
Factor , the Total: Scaling Value or the Rate:
Scaling Value parameters.
0-9 Switch
Located under each decade, these switches are used to set the value of all programmable
parameters. Each depression increments the display one digit. Holding the switch depressed steps
the display through
0 to 9 at a pre-determined rate.
+/- Switch
Located at the lower left hand corner of the front panel, this switch has no function on 2000CT
models.
