Remove the test leads and charger. Turn off the calibrator.
Remove the protector (if attached).
Using a standard blade screwdriver, turn each battery door screw a quarter counterclockwise to remove the battery door.
Install four new AAA alkaline batteries, ensuring correct polarity as indicated on the holder.
Reinstall and tighten the battery door, then reattach the protector.

Battery Level Indication:

The battery replacement indicator shows the battery level in five steps. Replace batteries when the low battery indicator appears (flashing icon) to avoid false readings.

Connecting the Charger

⚠ Warning

The charger is for this specified product only.
Ensure AC power voltage matches the charger's rated supply voltage.
Do not short-circuit the charger's output plug.
Do not charge non-Ni-Cd, non-Ni-MH batteries or wasted batteries.

Turn off the calibrator.
