Please caref ully read th e instruction man ual before
using the test er, and pay spe cial attention to “Warnin g”
content. Ple ase follow i nstructions und er “Warn ing”.

1. Please be ver y careful wh en test voltage is higher
than AC 30 V, and do ke ep in mind that your fi nger
shall not exce ed the hand- shielding part of the
test probe.

2. Do not measur e voltage wh ich is higher than th e
allowed inpu t limit.

3. Before use, p lease chec k the meter and test probe;
do not carry out testing in ca se the test probe is
naked, tester housing is d amaged, or there is no
LCD display, etc..

4. It meets requirements o f safety standards only when
the meter is used together w ith the supplied test
probes. In case the test pro be is damaged and
needs replac ement, it is r equired to replace it with
a test probe of the same model a nd identical
electrical s pecifica tions.

5. Please neve r carry out an y voltage measure ment
whenever the test probe is i nserted in any current
outlet.

General Description

The 3-phase cl amp-type d igital power mete r is a hand­held intelli gent harmo nic power tester, wi th both func tions
of digital cur rent testi ng and power testin g. Th e tester is
comprised of t hree chann els including vol tage, curr ent,
and power as wel l as a micro sin gle chip system, an d it is
equipped wit h a powerful s oftware for measu rement and
data process ing functi ons; it can measure, calculat e,
and display vo ltage, cur rent, active powe r, power fact or,
apparent pow er, passive p ower, frequency, harmo nic
parameters , with stabl e performance and o peration
convenienc e. Th e meter is esp ecially suitabl e for the
measuremen t and examin ation of on-site po wer
equipment an d power-su pplying circuit s; with hand -held

clamp struct ure, small v olume, and light weight, it can
be easily carr ied by the use r, which makes it easy a nd
fast for doing m easureme nt. For measurement of sing­phase/thre e-phase po wer, The meter i s your ideal
choice

Features

1.The meter can b e used for tes ting power, voltag e,
current, peak value, pha se, frequency, power fa ctor,
phase angle, a nd reactio n factor, etc. of single-/
three-phas e circuit; a utomatic phase sequence
testing is possible for 3- phase measurement.

2. True effective va lue measur ement: accurate
measuremen t is possibl e even with serious
distortion i n current wa veform.

3. Low-consu mption hig h-speed single- chip
microproce ssor is empl oyed and sophisti cated
algorithm is a pplied, as a r esult, results can be
obtained rap idly and pre cisely, and up to 20
harmonics an d distorti on value thereof can be
measured.

4. It is equippe d with a large -size memory for saving
up to 100 groups o f test param eters.

5. It is equippe d with RS232 C communication a nd
recording in terface an d dedicated WINDOWS
graphics sof tware.

6. Hand-held , clamp-ty pe structure, with light weig ht,
convenient for carry-o n.
