INSTRUCTION
MT-3102 3 1/2 mini digital clamp meter is a 3 1/2-digit LCD
multi-meter for measuring AC and DC voltage, AC current,
resistance, temperature, Diode and continuity test. All overload
protection is provided. The function/range rotatable switch
design makes manual operation workable, and range selector,
power switch are all on one know. The select buttons for easy
function change. It is ideal instrument for use in fields, factory,
college and laboratory.
SAFETY INFORMATION
This digital clamp meter has been designed according safety
standard IEC-61010-I and LECI010-2-032 concerning electronic
measuring instruments with an
over voltage category（CAT II
600V）and pollution degree 2

SAFETY WARNING
1.
Read the operating instructions before using the
instrument and pay particular attention to all WARNINGS
and CAUTIONS in this instruction manual.
2.
Be sure that the cover and the test leads of the meter are
in good conditions.
3.
Set the range / function switch at the correct position when
measuring.
4.
Make sure to insert the red and the black test leads to their
appropriate jacks. The black test lead should be connected
first when measuring while the red test lead should be
disconnected first after measuring.
5.
When the range and function changes, both test leads
should be disconnected.
6.
To avoid damage to the instrument, never exceed the
allowable maximum input of each range.
7.
Be care of electric shock hazard when the voltage to be
tested is above DC 60V or AC 30V.
8.
To avoid electric shock, do not open the battery
compartment cover when making measurement.
9.
Remove the test leads from the circuit being measured
before replacing the battery.
10.
Do not change the built-in circuit to avoid damage to the
meter.
11.
Do not use or store the instrument in an explosive
atmosphere (i.e. the presence of flammable gas or fume,
vapor or dust）
12.
CAT II-Measurement Category II is for measurements
performed on circuits directly connected to low voltage
installation.（Examples are measurements on household
appliances, portable tools and similar equipments.）
Dot not
use the meter for measurements within Measurement
Categories III and IV

BUTTON FUNCTION AND AUTO POWER OFF
1. HOLD: For measuring data hold, press the HOLD button,
the peak value of current data will be keeping displaying on
LCD; press it again to cancel this function
2. MAX: Maximum data hold button, when press this button,
the A/D converter will keep measuring, and the display
updating the data and hold the maximum data
3. SELECT：
Function selection button, press for switching ohm
/ diode /continuity/ temperature function when tested objects
change
4. Auto-power off : If there is no any operation within any fifteen
minutes after power is on, the meter will auto power off. Turn
the rotary selector or press any function button to resume
operation of the meter under the auto power off mode. At the
same time when power on, if press the ”HOLD” button, auto
