Warnings
•Read, understand and follow the Safety Rules and
Operating Instructions in this manual before using
this instrument.
•The tester’s safety features may not protect the user
if not used in accordance to the manufacturer’s
instructions.
•Keep fingers away from the metal probe tips when
taking measurements.
•Comply with all safety codes. Use approved personal
protective equipment when working near live electrical
circuits.
•Use caution on live circuits. Voltages above
30V AC RMS, 42V AC peak, or 60V DC pose a shock
hazard.
•Do not use if the instrument or test leads appear
damaged.
•Verify tester’s operation by measuring a known voltage.
•Do not use the tester in wet or damp environments or
during electrical storms.
•Do not use the tester near explosive vapors,
dust or gasses.
•Do not use the tester if it operates incorrectly.
Protection may be compromised.
•Do not apply voltage that exceeds the tester’s
maximum rated input limits.
