2.2
Batteries
The 27MG Ultrasonic Thickness Gage comes with three AA-sized alkaline batteries.
The 27MG instrument can also be operated using three AA-sized nickel-metal
hydride (NiMH) rechargeable batteries. The 27MG does not recharge NiMH batteries.
To recharge the batteries, you must use a commercially available external battery
charger (not included).
2.2.1
Battery Operating Time
The battery operating time depends on the type of batteries being used, the age of the
batteries, and the instrument settings. To provide realistic battery operating times, the
27MG Ultrasonic Thickness Gage has been tested with mid-level operating
parameters (update rate set to 4 Hz).
The nominal alkaline battery operating times for new batteries is 150 hours under
normal conditions (typical 30 hours continuous with back light). The battery symbol
in the bottom right corner of the display indicates remaining battery level.
2.2.2
Battery Level and Storage
When the batteries are full (100 % level), the battery power indicator will show four
bars (see Figure 2-1 on page 23).
When the 27MG instrument is not being used for a prolonged period of time, remove
the batteries and store them by doing the following:
•
Store batteries in a cool, dry environment.
•
Avoid long-term storage under sunlight, or in other excessively hot places such as
the trunk of an automobile.
2.2.3
Battery Replacement
The batteries are located in a compartment that is accessible from the back of the
27MG (see Figure 2-2 on page 25).
