BATTERY REPLACEMENT

This meter uses six AA (1.5 V, UM3) batteries. When the
low battery indicator appears on the LCD, battery
replacement is needed. After the icon appears on the LCD,
in-spec measurement can still be made for several hours
before becoming inaccurate.

1. Press POWER to turn the meter off.

2. Unscrew the battery cover and remove from the meter.

3. Remove the old batteries and replace with six new

AA batteries, ensuring correct polarity.

4. Replace the battery cover. Tighten the screws on the

battery cover to secure to the meter.
