Battery Life
Table 12 shows typical alkaline battery life. To preserve
battery life:
Measuring any parameter
Simulating Current
Sourcing 12 mA into 500
To avoid false readings, which could lead to
possible electric shock or personal injury,
replace the battery as soon as the battery
indicator (B) appears.
Use current simulation instead of sourcing when
possible.
Avoid using the backlight.
Do not disable the automatic power-off feature.
Turn the meter off when not in use.
