Frequently asked questions

What happens if I measure current on a circuit with voltage exceeding 600V?

Do not measure current on a circuit whose voltage exceeds 600V.

What should I do before performing Diode, Resistance or Continuity tests?

Always discharge capacitors and remove power from the device under test.

How do I select Fahrenheit or Celsius units for temperature?

See the "Temperature Units" paragraph in the manual to select °F or °C.
