I. General
It is a 3 3/4-bit digital clamp meter of automatic
range conversion and a high-reliability digital clamp
multimeter with stable performance and driven by
battery. It adopts 16mm font height LCD display of
clear readings. With the functions of data holding and
automatic power-off, it is more convenient to use.
This meter can be used to measure such parameters
as DCV, ACV, DCA, ACA, resistance, capacity,
frequency, diode, continuity test, etc. Centered on the
dual slope A/D conversion of large-scale integrated
circuit, the whole set has the function of automatic
range conversion and thus is a meter with excellent
performance and a desirable tool for labs, factories,
radio fans and homes.
Warning: Before use, please read carefully
the information under “Safety Notices”.

III. Safety Notices
Please note warning mark “ ” and the
sentence titled with “Warning”, which represent the
circumstances or actions that endanger the user,
may cause damages to the clamp multimeter or the
tested equipment.
This meter is designed and produced strictly in
accordance with the safety requirements of GB4793
electronic measuring meters and IEC61010-1 and
IEC1010-2-032 Safety Standards and conforms to the
safety standards of double insulation and over-voltage
3
CAT III 600V and Grade II pollution. Before use,
please read this manual carefully.
1. When measuring the voltage above 30V, the AC
electric line with inductive loads and the AC electric
line during electric fluctuation, be cautious against
electric shock.
2. Before measurement, check if the measurement
function switch is at the proper gear, check if the test
probe touches the measured item reliably, with
proper connection, good insulation, etc, in order to
avoid electric shock.
3. The clamp multimeter cannot conform to the
requirements of the related safety standards until it is
used together with the attached test probe. If the test
probe cable is broken, it must be replaced with the
cable of the same type or the same electric
specifications.
4. Do not use any other batteries not confirmed or
unauthorized to replace the battery of the meter; do
replace the battery with only the battery of the same
type or the same electric specifications. Before
replacing the test probe, keep it away from the
4
measured point and make sure there are no signals on
the input end.
5. During the electric measurement, never directly touch
the ground or touch naked metal terminals, output
ports, lead clamps, etc that may have ground
potential.
6. Do not store and use the meter in the environment of
high temperature, high humidity, high flammability,
high explosion potential and strong magnetic field.
7. Measuring the voltage out of the allowed limit
voltage may damage the meter and endanger the
operator. The allowed limit voltage is marked on the
panel of the meter. Never measure the input signal
out of this standard in order to prevent electric shock
and damage on the meter.
8. Do not attempt to calibrate or repair this meter.
Surely, when necessary, the calibration and repair
must be conducted by specially trained personnel or
qualified professional personnel.
9. During measurement, the function/range selection
switch must be placed at the correct range gear.
When converting the function/range selection switch,
5
be sure to disconnect the test probe cable from the
tested item and make sure there are no signals input
into the input end. Never convert the function/range
selection switch during measurement.
10. When the LCD display shows “ ”, please
replace the battery in time to ensure the
measurement accuracy.
11. Do not change the circuits of this meter without any
permission to avoid damaging this meter and
endangering safety.

VII. Functions of Keys and Automatic Power-off
(1) SELECT: Selects functions in the trigger mode.
When two or above measurement functions combine
at the same gear, press this key to convert
measurement functions.
(2) HOLD: Holds readings in the trigger mode. Press
this key to lock the displayed value and press it
again to relieve the locking state and then enter the
normal measurement state.
(3) REL: Measures relative values in the trigger mode.
Press this key at the DCA gear and then this meter
will regard the currently displayed value as the
reference value and automatically reset the LCD
display. In the subsequent measuring results, the
reference value will be automatically deducted until
the relative value measurement function exits by
pressing this key again.
Automatic power-off function: During
measurement, whether pressing function keys or
rotating function/range selection button, if idle for
15min, the meter will automatically “power off”. In
such state, press the function keys (for effective key
operations, see VIII) or rotate the function/range
selection button, then the meter will automatically
“Power on” and enter the measurement status. To
power off the meter, hold the SELECT key, then
the automatic power-off function will be cancelled.
“Auto Power-off” represents a sleep status. In such
state, a small amount of current (approximately
