WARNING
Never connect the test leads across
(in parallel with) a voltage source
when attempting to measure current.
This can cause damage to the circuit
under test or this meter.
Note: To measure current, you must
create a break in the circuit under test
and make the meter part of the circuit.
Two connection points are created when a
circuit is broken. On one side is the power
source and the other is the load.
ACCURACY
±(1.5% +5 dgts)
±(0.5% +5 dgts)
The meter measures the frequency of
a voltage or current signal by counting
the number of times the signal crosses a
threshold level each second. To measure
Frequency, set selector dial AC Volt or
Milliamp position. In the mA position, press
the SELECT button to select AC, if needed.
Press the PI/DAR button.
