Frequently asked questions
How do I measure current with the clamp?
Select the AC or DC current range, then clamp the jaw around a single conductor. Do not clamp both the live and neutral wires together, because their fields cancel and the reading will be wrong.
What are the maximum voltage ratings?
The listed limits are 700 V for AC voltage and 1000 V for DC voltage. Do not exceed these limits, and use the meter's test leads with care when measuring live circuits.
