•
Be careful when working above 30 V ac rms, 42 V
ac peak and 60 V dc. Such voltages pose a shock
hazard.
•
When using the probes, keep fingers away from
probe contacts. Keep fingers behind the finger
guards on the probes.
•
Measurements can be adversely affected by
impedances of additional operating circuits
connected in parallel or by transient currents.
•
Verify operation on a known source prior to
measuring hazardous voltages (voltages above
30 V ac rms, 42 V ac peak and 60 V dc).
•
Do not use the apparatus with any of the parts
removed.
•
Do not use the apparatus around explosive gas,
vapor, or dust.
•
Disconnect the test leads from power sources and
the apparatus before changing the battery.
•
Do not use the apparatus in a wet environment.
