5. Setup

5.1 Battery Installation

The multimeter requires two 1.5V AAA batteries (not included) for operation. To install or replace batteries:

1. Ensure the multimeter is turned OFF and disconnect all test leads.
2. Locate the battery compartment cover on the back of the unit.
3. Use a screwdriver to open the battery compartment.
4. Insert two AAA batteries, observing the correct polarity (+/-) as indicated inside the compartment.
5. Replace the battery compartment cover and secure it with the screw.

5.2 Connecting Test Leads

Proper connection of test leads is crucial for accurate and safe measurements.

• Insert the black test lead into the 'COM' (Common) input jack.
• Insert the red test lead into the 'VΩHz' input jack for voltage, resistance, frequency, and diode measurements.
• For current measurements (mA/A), insert the red test lead into the 'A mA' input jack. For microampere measurements (uA), insert the red test lead into the 'uA' input jack.
