Safety & Warnings
The manual includes several safety precautions:
1. Ensure batteries are installed correctly.
2. Verify that the LCD and range indicator match the desired function.
3. Remove the tested conductor or electrical circuit from the clamp jaw before changing the range to avoid damage.
4. Avoid strong vibrations and impacts to prevent instrument damage.
5. Do not test or connect to circuits with voltage or current exceeding the specified overload protection.
6. When measuring resistance, do not apply any voltage to avoid meter damage, even though there is a protection circuit.
7. Remove test leads from common and voltage/resistance jacks when measuring current.
8. Strong currents near the clamp jaw can affect accuracy.
9. The instrument is not suitable for non-sine wave AC signals, as this will result in significant errors.
10. Place the tested conductor in the center of the clamp jaw for accurate readings.
11. If the reading or sign remains unchanged, check if the DATA HOLD function is active.
12. Replace batteries immediately when the BAT symbol appears on the LCD to avoid incorrect data.
13. Do not touch the circuit board when changing the battery to prevent static electricity damage.
14. Ensure all test leads are disconnected from the meter’s terminal when measuring current.
15. Do not attempt to measure voltage exceeding 600V for DCV or ACV to prevent electrical shock and damage to the clamp meter.
