APPENDIX C - OPERATION WITHOUT THE DOCKING-STATION
1. DESCRIPTION
The figure shows the necessary hardware requirements for non-DS operation. Normally the GR-
135 is supplied with a DOCKING-STATION (DS) but additional accessories are available. For non-
DS use, the user needs a TEST SOURCE and a POWER CABLE, these optional items are:
a) TEST SOURCE
- PN 87046-1 – 0.25uCi Cs-137 Test Source
b) POWER CABLES
- PN 92309-1 – 220VAC (Europe) – 12V DC assembly
- PN 92309-2 – 220VAC (UK) – 12V DC assembly
- PN 92309-3 – 115VAC (Australia) – 12V DC assembly
- PN 92309-4 – Universal 115/220VAC (North America) – 12V DC assembly
- PN 87387-1 – Cigarette lighter plug - 12V DC assembly
2. STABILIZATION
Stabilizing the GR135 outside the DS depends on the MODE of operation.
a) MANUAL MODE
From the MAIN MENU select STABILIZE then proceed as described in Section 7.3 except in
this case the source is held against the face of the unit rather than sitting the unit in the DS.
b) AUTOMATIC MODE
In this case it is necessary to let the unit think it is in the DS as the Automatic mode functions
are optimized for this mode of operation. This is easily done as follows:
- place the Test Source against the face of the instrument
- plug in one of the sources of external power shown above in the figure
- as long as external power is supplied the unit will continue to automatically stabilize as
described in Appendix A
NOTE – if the Test Source is removed an error message will appear on the display
3. BATTERY CHARGING
The battery charger is integrated into the GR-135 electronics so the external “battery charging” is
really supplying 12VDC to the unit to charge the two “D” cell NiCd batteries in the GR-135
without removing them from the instrument.
