Read First: Safety Information
To ensure that the meter is used safely, follow these instructions:
•
Do not use the meter if the meter or test leads appear damaged, or if
you suspect that the meter is not operating properly.
•
Disconnect the live test lead before disconnecting the common test
lead.
•
When using the probes, keep your fingers behind the finger guards on
the probes.
•
Do not use the Model 12B’s Automatic Selection mode to measure
voltages in circuits that could be damaged by this mode’s low input
impedance (
≅
2 k
Ω
).
•
Turn off power to the circuit under test before cutting, desoldering, or
breaking the circuit. Small amounts of current can be dangerous.
•
Do not apply more than 600V rms between a meter terminal and earth
ground.
•
Use caution when working with voltages above 60V dc or 30V ac rms.
Such voltages pose a shock hazard.

Warning
To avoid false readings, which could lead to possible electric shock
or personal injury, replace the battery as soon as the battery
indicator (
U
) appears.
