IMPORTANT NOTES:

1. Battery protector must be removed before use.

2. Do not perform continuity tests on live or powered circuits. Performing continuity tests on live or powered
circuits may damage the tester.

3. The polarity indicator LED will show purple to indicate AC power is present. Do not perform any tests
when AC power is present.

4. The tester is intended to test 12VDC or 24VDC. Do not exceed 30VDC.

5. Load testing takes no longer than a few seconds. Significant heat is normal when load testing but
pressing the load button for too long will cause the unit to overheat and shutdown.

6. When load testing, wait 30 seconds between tests to allow the unit to cool.

7. Always store the unit in Voltage Test mode to prevent draining to battery.

8. The LED Light is for providing temporary illumination. Extended use will quickly exhaust the batteries.
