Automatic Power-Off

The Meter automatically turns off if you do not turn the
rotary switch or press a button for 30 minutes. If MIN
MAX Recording is enabled, the Meter will not power off.
Refer to Table 5 to disable automatic power-off.
Input Alert™ Feature
If a test lead is plugged into the mA/μA or A terminal, but
the rotary switch is not set to the correct current position,
the beeper warns you by making a chirping sound and
the display flashes "", This warning is intended to
stop you from attempting to measure voltage, continuity,
resistance, capacitance, or diode values with the leads
are plugged into a current terminal.
W Caution
Placing the probes across (in parallel with) a
powered circuit when a lead is plugged into a
current terminal can damage the circuit you
are testing and blow the Meter's fuse. This
can happen because the resistance through
the Meter's current terminals is very low, so
the Meter acts like a short circuit.

Power-Up Options

Holding a button down while turning the Meter on
activates a power-up option. Table 5 describes power-up
