Charging an Instrument in a Docking Station
The SDM-2009 can be used to charge the rechargeable batteries in a GX-2009. To
maximize the instrument’s run time and the battery life, make sure the batteries’
charge is as low as possible before recharging them. You can use the GX-2009’s
REFRESH function to discharge the batteries. See the GX-2009 Operator’s Manual
for a complete description of the REFRESH button.
Recharging the Batteries After Performing a Bump Test
or Calibration
1.
Perform a bump test or calibration on an instrument as described in “Bump
Testing a GX-2009” on page 23, “Calibrating a GX-2009” on page 29.
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.
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-2009 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.
4.
If the batteries are fully charged, then the CHARGE LED will turn solid green in
a few minutes.
If the batteries are drained enough for the docking station to charge them, the
CHARGE LED will continue to blink amber while charging is taking place. The
SDM-2009 will take approximately 3 hours to charge a fully discharged
GX-2009.
If the charging process encounters a fail condition, the CHARGE LED will turn
steadily red.
NOTE:
If the GX-2009 is left in the SDM-2009 after bump testing or calibration,
the pump will run for 12 seconds every 2 minutes in order to keep
hydrogen generated from charging of the NiMH batteries from affecting
the CO sensor.
5.
When the charge is complete, the CHARGE status LED will turn solid green.
