Recharging the GX-2001’s Battery Pack

WARNING: To prevent ignition of a hazardous atmosphere, batteries

must only be changed or charged in an area known to be
nonhazardous.

CAUTION: To be used with RKI Ni-cad battery pack p/n 49-1602RK or Ni-

MH battery pack 49-1605RK. Charge only with RKI charger p/
n 49-2155RK or 49-2156RK.

1. Verify that the Model GX-2001 is off.

2. Plug the battery charger’s AC power cord into an electrical outlet.

3. Place the Model GX-2001 in the battery charger.

NOTE: There are two optional battery chargers for the Model GX-2001.

Both may be powered from 100-240 VAC 50/60 Hz. One battery
charger has a PC communication feature for datalog downloading.
See “Parts List” for more information.

4. While the unit is being charged, the red LED on the top face of the

charger is on.

5. When the red LED turns off, the GX-2001’s battery pack is fully

charged. It takes approximately 90 minutes to recharge a fully
discharged battery pack.

6. To verify whether the battery pack is fully recharged,

remove the unit from the battery charger, then press the
MODE/POWER button to start up the unit. If the battery
icon on the LCD is fully colored in, then the unit has been
completely recharged.

NOTE: A battery pack will have a typical service life of 500 charging

cycles minimum.

When using the GX-2001, be sure to drain the battery as much as possible
before recharging. If the battery is regularly only partially drained before
charging, the battery will experience a “memory effect” and the run time of
the instrument will be decreased.
