Charging an Instrument in a
Calibration Station
The SM-2001U and SM-2003U calibration stations can be used to
charge the rechargeable battery pack in a GX-2001 or GX-2003. A
calibration station will not recharge the batteries in an alkaline version of
the GX-2003. To maximize the battery pack run time and the battery pack
life, make sure the battery pack’s charge is as low as possible before
recharging it.
To recharge the battery pack in an instrument after performing a bump
test or calibration:
1. Perform a bump test or calibration on an instrument as described
in “Bump Testing Instruments” on page 22 or “Calibrating
Instruments” on page 25 or “Bump Testing and Calibrating a GX-
2003 with 100% Volume Methane” on page 28.
2. After the bump test or calibration has been completed, turn off the
instrument by pressing and holding the BUMP and VOL. control
buttons simultaneously for at least one second and then releasing
them. If no control buttons are pressed for 10 minutes, the
calibration station will automatically turn off the instrument.
3. After a few seconds, the CHARGE status LED on the right front of
the calibration station will start blinking yellow. The CAL. status
LED on the front left of the calibration station will continue to be
either green or red depending on the result of the bump test or
calibration.
