Meaning
Data hold is active.
Sleep Mode indicator
Indicates negative reading.
Indicator for AC measurement
Indicator for DC measurement
The Meter is in the auto range mode
in which the Meter automatically selects
the range with the best resolution.
Indicator for manual ranging mode.
The input value is too large for
the selected range.
Transistor testing indicator
Test of diode
The continuity buzzer is on.
Maximum and Minimum reading.
Data output is in progress
The battery is low.
Warning: To avoid false readings, which
could lead to possible electric shock or
personal injury, replace the battery as
soon as the battery indicator appears.

To avoid harms to you or damages to the
meter from electric shock, please do not attempt
to measure voltages higher than 1000V although
readings may be obtained.
When measuring high voltage, take extra care to
avoid electric shock.
1. Insert the red test lead into the V terminal
and the black test lead into the COM terminal.
2. Set the rotary switch to V; DC measurement in
default or press BLUE button to switch between
DC and AC measurement mode.
WARNING
3. Connect the test leads across with the object
being measured. The measured value shows on
the display. Display effective value of sine wave
(mean value response).

Note
• In each range, the Meter has an input impedance
of 10M
Ω
except mV range which input impedance
is 3000M
Ω
. This loading effect can cause
measurement errors in high impedance circuits.
If the circuit impedance is less than or equal to
10k
Ω
, the error is negligible (0.1% or less).
• When measuring mV, you must press RANGE
manually to enter mV range.
• When voltage measurement has been completed,
disconnect the connection between the testing
leads and the circuit under test, and remove the
testing leads away from the input terminals of
the Meter.
Before connecting the Meter to the return
circuit to be tested, cut off the current of the return
circuit.
If the fuse burns out during measurement, the
Meter may be damaged or the operator himself
may be hurt.
Use proper terminals, function, and range for the
measurement.
