Program operator’s manual for data logging and downloading
instructions.
Buzzer
One solid-state electronic buzzer is located inside the case. Holes on
the top front of the case allow the sound to exit the case. The buzzer
sounds for gas alarms, malfunctions, low battery voltage, and as an
indicator during use of the Gas Tracer’s many display and adjustment
options.
Vibrator
A vibrating motor inside the Gas Tracer case vibrates for gas alarms,
unit malfunctions, and as an indicator during normal use of the
various modes of the Gas Tracer.
Batteries
Three AA-size alkaline batteries (standard) or an optional
rechargeable lithium ion battery pack (3.7 VDC) power the Gas Tracer.
Instrument run time is dependent upon battery type. At 25°C the
alkaline batteries last up to 15 hours and the lithium ion battery pack
lasts up to 10 hours. The battery icon in the upper right of the LCD
shows remaining battery life.
When the Gas Tracer detects a low battery voltage, a low battery
warning is activated. When battery voltage is too low for normal
operation, the Gas Tracer sounds a dead battery alarm.
The alkaline batteries can be replaced by removing the battery cover
on the back of the case. The lithium ion pack can be replaced by
removing the entire battery pack. Push the battery pack latch on the
bottom of the unit toward the front of the unit to release the pack.
The lithium ion battery pack can be recharged by placing the Gas
Tracer in its optional battery charging station or by placing the battery
pack in the charging station.
NOTE: Use of batteries or battery chargers not specified by RKI
Instruments, Inc. will void the CSA classification and may
void the warranty. See “Replacing or Recharging the
Batteries” on page 85.
