accordi ng to Safet y Standard IEC61010-1
IEC6101 0-2-032 f or electronic measuring i nstrume nts
and hand- held curr ent clamps. It conforms to sa fety
standar ds for doub le insulation CAT III 600 V and
grade 2 for p ollutio n.
Safety Signs
Impor tant safet y sig n. Refer to th e operatio n manual.
Danger hi gh voltag e.
Double in sulatio n (Safety equipment with cl ass II).
Ground (e arth).
Allow to be u sed aroun d conductors without
danger to l ife.
Notes
• Before us ing this me ter, please read carefully t his
user manu al and pay sp ecial attention to “warni ng”
content . Please fo llow the “warning” instru ctions.
• To meet the saf ety requi rements, only use probe
supplie d with the me ter. If the probe is replaced,
a new one wit h the same mo del or same electric
specifi cation sh ould be used.
• Before us ing it, ple ase check the meter and probe
for any dam age or abno rmal condition. If an
abnorma l situati on appears (for example: ba re
probe, en closure d amage, no liquid crystal di splay,
etc), don 't use the me ter.
• When the me ter is meas uring, don't touch the unus ed
input ter minal.
• Be carefu l when meas uring voltage greater tha n 60V
DC and 30V AC. D on't allo w fingers to touch or block
part of the p robe.
• When you ca n't deter mine the size range of signal t o
be tested , please sw itch the function measuri ng range
to the maxi mum posit ion, then gradually selec t lower
ranges un til the cor rect range is found. Do not exc eed
the input l imit spec ified in each measuring ran ge.
• Don't mea sure volt age greater than the upper li mit for
each rang e.
• Before ch anging th e function measuring rang e switch
to a diff erent pos ition, se t the probe and the ci rcuit
being tes ted to an ope n state.
• Before on line resi stance measurement, tur n off all
power sup plies in ci rcuit and release all charg es on
both ends o f capacit or.
• Don't exp ose the met er exposure to strong light , high
tempera ture or moi sture (humidity).
• Don't tou ch bare wir es, connectors or circuit s being
measure d.
Maintenance
• Before op ening the m eter back cover, make sure tha t
the probe i s removed f rom the circuit to be measure d.
• Only wet cl oth and a sma ll amount of detergent can
be used for c leaning t he meter. Don't use chemical
solvent s to wipe the m eter case.
• If you find a ny abnorm al conditionon the meter, st oop
using the m eter imme diately and have it repaire d.
• Repair th e meter wit h the help of a trained technic ian.

AC Voltage Measure ment
1. Inse rt red probe to “INPUT” jack and in sert black
probe t o “COM” jack.
2. Plac e function measuring range sw itch to AC
volta ge measuring range, and conne ct the probe
to the power source or load to be tested. The

AC Current Measurement
1. Plac e function measuring range sw itch to AC
curre nt measuring range.
2. Pres s the trigger, open clamp head, clip the lead
in the cl amp to measure the lead current . Note:
Clamp ing two or more leads at the same tim e will
give in valid reading.
3. Read t he measuring result from disp lay.
Notes!
∆ If the range of current to be tested is not known in
advan ce, please place function mea suring switch
to the maximum current range, then gradually
reduc e to obtain the correct range.
Resistance Measurement
1. Inse rt red probe and black probe to “IN PUT” and
“COM” jack.
2. Plac e function measuring range sw itch to required
Ω position, and connect the probe to resistor to
be tested.
3. Read t he measuring result from disp lay.
Note:
∆ If measured resistance value is more than the
maxim um value of chosen measuring ra nge, it will
show wi ll “OL`”. At th is time, select a higher range.
∆ When ch ecking online resistance, f irst turn off all
power s upplies in the circuit to be meas ured and
disch arge all capacitors fully.
∆ When me asuring the resistance more t han 1MΩ,
the rea ding will be stable after sever al seconds.
This is norm al for high resistance measur ing.
Diode Test
Inser t red probe to “INPUT” and insert black probe to
“COM” j ack. At this ti me, red probe polarity is “+”.
Place f unction measuring switch to position. Red
probe i s connected to the anode of diode u nder
measu rement, and black probe is conn ected to the
catho de of diode under measurement . Read
appro ximate forward voltage drop v alue from the display.
Circuit Continuity Test
Inser t red probe to “INPUT” jack, and insert black
probe t o “COM” jack. Place function me asuring switch
to position and press SEL key to enter circuit
conti nuity test. Probe is connecte d to two points of
circu it under measurement. In cont inuity test, when
test re sistance is less than 50Ω, buzz er will sound.
When it i s from 50Ω to 90Ω, buzzer may or may not
sound . When it is more than 90Ω, buzzer wo n't sound.
Non-Contact Volt age Detection
Press N CV key. Place non- contact sensor close to the
condu ctor. When te st voltage is greater than 90V AC
(RMS) a nd when the meter is close to the con ductor,
the met er induction voltage indica tor will flash and
buzze r will sound.
Note:
1: Even t here is no indication, voltag e may exist. Don't
use non -contact voltage detector to judge whether
there i s voltage in the wire. Detectio n operation
could b e aff ected by socket design, insul ation
thick ness, type and other factors.

2: When i nputting voltage on the meter i nput terminal,
due to the existence of the induced voltage, voltage
induc tion indicator also may light .
3: Inte rference sources of externa l environment (such
as flas hlight, motor, etc.) may trigger non-con tact
volta ge detection by mistake.

In order to e xtend the b attery life, the meter has an
automat ic shutdo wn function. If there is no key
operati on or funct ion measuring range chang e
within 15 m inutes, t he meter power will disconn ect
automat ically. Press “SEL” button to retur n the
meter to th e working s tate again.
Replace Battery
To avoid e lectric s hock, disconnect the prob e
before op ening bat tery cover. Disconnect any
circuit o r signal be ing tested. Use only a
battery w ith the sam e model or same electric
specifi cation.
Warning
If “ ” symbol a ppears, i t means that the battery
should be r eplaced . Before opening the meter ba ck
cover, mak e sure that n o probe is connected to the
circuit . Check tha t the back cover is tightened
before us ing the met er., Follow these steps to
replace t he batter y:
1. Discon nect the pr obe and remove it from the
input jac k. Switch r otating function measur ing
range swi tch to “OFF ”.
2. Unscre w screws on t he battery cover and remove
the batte ry cover.
3. Take out the old batt eries and r eplace with three
