BEFORE YOU TRUST IT
Field-use checks
- 01Inspect the case, display, input jacks, leads and probe insulation before every use.
- 02Confirm the selector and lead locations before touching the circuit.
- 03Prove the meter on a known source before and after verifying absence of voltage.
- 04Use a clamp for current when it is the safer and correct measurement method.
04
RED FLAGS
What to avoid
- Unmarked meters with unclear circuit ratings
- Damaged or mismatched leads and accessories
- Buying on maximum-count marketing while ignoring protection and service support
