Buzzer/Vibrator
A solid-state electronic buzzer/vibrator is mounted inside the front case of
the Model GX-2001. The buzzer/vibrator sounds and vibrates for gas
alarms, and it sounds for unit malfunctions, low battery voltage, and as an
indicator during normal use of the many display options of the Model GX-
2001.
Battery Pack
Inside the Model GX-2001 is either a Ni-cad or Ni-MH battery pack that
supplies 2.4 V to the unit. The battery will run the unit for approximately 10
hours (Ni-Cad) or 18 hours (Ni-MH) when no alarms have been activated
during that time period. The battery is fully rechargeable when the Model
GX-2001 is placed into the battery charger. The battery icon on the LCD
shows the charge remaining in the battery. When the Model GX-2001
detects a low battery voltage, a low battery warning is activated. The
battery can be replaced by removing the belt clip on the back of the Model
GX-2001. See the maintenance section of this manual for instructions
about recharging and replacing the battery.
Belt Clip
On the back of the Model GX-2001 is a belt clip. The belt clip permits the
unit to be worn on a belt or to be clipped to a pocket for hands-free gas
monitoring. The belt clip may oriented as shown in Figure 1 or rotated 180°.
See the Maintenance section for instructions on how to rotate the clip.
Battery Charger
The Model GX-2001 has three battery charger accessories available. All
three are used to recharge the unit’s battery pack and serve as a
convenient station for auto calibration. The battery charger with the PC
communication feature has a datalogging port for the down loading of data
from the Model GX-2001 to a computer and allows autocalibration using a
computer. See “Parts List” for more information.
