3.
Open the circuit path to be tested. Touch the red probe to the
more positive side of the break and touch the black probe to the
more negative side of the break. (Reversing the leads will
produce a negative reading, but will not damage the meter.)
4.
Turn on power to the circuit and read the display.
5.
After measuring current, turn off power to the circuit and
discharge all high-voltage capacitors. Disconnect the meter and
restore the circuit to normal operation.

Wrong Input Warning Feature
If the display shows
or Fuse, be sure the meter is set up correctly
and test the meter’s fuses as described under “ Auto Fuse Detection ”
in item 6.2. If the rotary switch is not correctly set to one of the current
measuring positions, the beeper warns you by making a chirping sound.
This warning is intended to stop you from attempting to measure the
other values when the leads are plugged into a current terminal.
Placing the probes 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 fuses because the resistance through the meter’s
current terminals is so low that the meter acts like a short circuit.

Auto / Manual Range Operation
Press the RANGE button momentarily to select manual-ranging, and
the meter will remain in the range it was in, when the LCD annunciator
AUTO
turns off.
Press the button momentarily again to step through the ranges. Press
and hold the RANGE button for two seconds or more to resume
auto-ranging.
5.9
Beeper
A single beep indicates correct operation. A double beep indicates a
warning or error condition. Continuous beeping indicates there is circuit
continuity while in continuity mode.
