4. Setup

4.1 Battery Installation

The Milwaukee 2212-20 requires two AAA batteries for operation. These are typically included with the kit.

1. Locate the battery compartment on the rear of the tester.
2. Use a screwdriver to open the battery compartment cover.
3. Insert two AAA batteries, observing the correct polarity (+/-) as indicated inside the compartment.
4. Replace the battery compartment cover and secure it with the screw.

Note: Remove batteries if the tester will not be used for an extended period to prevent leakage.

4.2 Connecting Test Leads

Connect the test leads to the appropriate input jacks on the tester.

• Insert the red test lead into the VΩ input jack (positive).
• Insert the black test lead into the COM input jack (common/negative).

5. Operating Instructions

5.1 Powering On/Off

Press the Power button (ⓘ) to turn the tester on. Press and hold the Power button for approximately 2 seconds to turn it off. The tester may also feature an auto-off function to conserve battery life.

5.2 Automatic Voltage Testing (AC/DC)

The 2212-20 automatically detects and displays AC or DC voltage.

1. Ensure the tester is powered on.
2. Carefully touch the red test probe to the positive or live point of the circuit and the black test probe to the negative or neutral/ground point.
3. The display will show the detected voltage and indicate whether it is AC or DC.

Always test on a known live circuit first to confirm the tester is functioning correctly.

5.3 Continuity Testing

The tester provides an audible and visual indication for continuity.

1. Ensure the circuit or component to be tested is de-energized.
2. Touch the red and black test probes to the two points you wish to test for continuity.
3. If continuity exists (low resistance), the tester will emit an audible beep and the display may show a continuity symbol or a low resistance value.

5.4 Backlight Function

Press the Backlight button (≡) to illuminate the display for better visibility in dimly lit environments. Press it again to turn off the backlight.

6. Maintenance

6.1 Cleaning

Wipe the tester with a dry, soft cloth. Do not use abrasive cleaners or solvents. Ensure the tester is dry before storage or use.

6.2 Test Lead Inspection

Regularly inspect test leads for any signs of damage, such as cuts, cracks, or frayed insulation. Replace damaged leads immediately to ensure safe operation.

6.3 Battery Replacement

When the low battery indicator appears on the display, replace the AAA batteries as described in Section 4.1. Always dispose of used batteries responsibly.

6.4 Storage

Store the tester in a clean, dry environment, away from extreme temperatures and direct sunlight. The back of the tester features integrated test lead storage for convenience.
