Charging an Instrument in a Docking Station
The SDM-2012 can be used to charge the rechargeable Li-ion battery pack in an
instrument equipped with it. To maximize the instrument’s run time and the battery
life, make sure the battery pack’s charge is as low as possible before recharging it.
Recharging a Battery Pack After Performing a Bump Test
or Calibration
1. Perform a bump test or calibration on an instrument as described in “Bump
Testing a GX-2012” on page 35, “Calibrating a GX-2012” on page 48, “Bump
Testing a Gas Tracer” on page 57, or “Calibrating a Gas Tracer” on page 75.
2. After the bump test or calibration has been completed, turn off the instrument
by pressing and holding the EDIT ENTER and POWER buttons
simultaneously until the instrument turns off, about one second, and then
releasing them. The docking station will automatically turn off the instrument
15 seconds after a successful bump test or calibration or if no buttons are
pressed for 10 minutes.
3. Be sure that the AC adapter is plugged into a wall outlet, that the power jack is
plugged into the back panel of the SDM-2012, and that the instrument is
properly installed in the front recess of the instrument cradle.
4. While the instrument is on, the CHARGE LED will be blinking green. When the
instrument is turned off, the CHARGE LED will blink amber. The BUMP
T
and/
or CAL
S
LED will continue to be either green or red depending on the result
of the previous bump test or calibration.
NOTE: The SDM-2012 does not start charging the batteries until the
instrument is off. While the instrument is on, the CHARGE LED will
blink green. Once the instrument is shut off, the CHARGE LED will
begin to blink amber.
5. If the battery pack is fully charged, then the CHARGE LED will turn solid green
in a few minutes.
If the battery pack is drained enough for the docking station to charge it, the
CHARGE LED will continue to blink amber while charging is taking place. The
SDM-2012 will take approximately 4 hours to charge a fully discharged battery
pack.
If the charging process encounters a fail condition, the CHARGE LED will turn
steadily red.
6. When the charge is complete, the CHARGE status LED will turn solid green.
