SAFETYINFORMATION

cSAFETYINFORMATION:

●To ensure that you use meter safely, follow the safety guidelines listed below.

●This meter is for indoor use, altitude up to 2000m.

●Avoid working alone. Take precautions when working around moving parts.

●Use the meter only as specified in this manual. Otherwise, the protection pro

vided by the meter may be impaired.

●Never measure current while the test leads arer inserted into the input termi

nals.

●Do not use the metr if it looks dameged.

●Inspect the leads for damage insulation or exposed metal. Check test lead

continuity. Replace damaged leads

●Disconnect the power and discharge all high-voltage capacitors before testing.

●Use caution when working above 60V DC or 30V AC RMS. Such voltages

pose a pose a shock hazard

●When making measurements, keep your fingers behind the finger guards on

the probe.

●Set the proper function and renge before attaching the metr to circuit. To avoid

damaging the meter disconnect the test leads from test points before changing

functions.

●Read this operation manual completly before using the meter and follow all

safety instructions.

●The meter is safety-certified in compliance with UL3111-1, C22.2 NO.1010.1-

92 and EN61010(IEC 1010-1, 1010-2031,IEC 1010-2-32) Instalation Category

ll 1000V or instalation Category lll 600V. In order to mantain its insulation

properties, please be sure to use ULListed Category ll 1000V or Category lll

600V probes.

●insrtallation category (CAT) ll is an environment with smaller trasient overvolt-

age than Installation Category lll.

●CE requirement: Under the influence of R.F field according to standard, the

supplied test leads will pick up induced noice. To have better shielding tests

are required in order to conform to CE:

1. IEC 801-2: ESD (electro-static discharge) test.

2. IEC-801-3: RFI (Radio frequency Interference) test.

Condition : 27 ~ 500MHz, signal intensity is 3 volts per meter.

3. IEC 801-4: EFT(electro-fast transient) test.

4. EN 55011: EMI (electromagnetic interference) test.

●Do not allow the temperature sensor to contact a surface which is energized

above 30 V RMS or 60V DC, such voltages pose a shock hazard.

AUNIQUE CLAMP-ON MULTIMETER

cINTRODUCTION

Measuring current accurately is difficult job in today's industrial plants and com-

mercial buildings.An increasing number of personal computers, adjustable

speed motor drivers, and other types of electronic equipment in short pulses and

are reffered to as non-linear loads.

non-linear loads draw high peak current, causing harmonics in the load current.

this may result in unexplained circuit breaker tripping, or dangerous overheating

of neutral conductors and transformers. Currents containing harmonics can only

be accurately measured with a true rms or clamp meter. this CLAMP-ON MULTI-

METERis shown in Figure1.

This meter has many functions which are shown below:

●TRUE RMSmeasurement for non-linear and traditional loads.

●1ms Peak. Hold feature to capture glitch or in-rush current.

●Differentiation reading for Dual temperature measurement.

●Start capacitor measurement.

●Dynamic Recording helps to record the variation of test.

●Hand Guard for prevention of accidental contact with conductors.

●Carryng case with shoulder strap

●Data Hold to freeze displayed digital value.

●Relative(zero) function

●Auto and Manual Ranging

cWARNING

Read " SAFETYINFORMATION" before using the meter..

cNOTE

Some typical tests are provided in this manual. These tests are designed to help

you understand how to use the Meter. Consult original manufacturer service

manualfor the test procedures that apply to your particular piece of equipment.

Your Clamp-on multimeter is a hand-held, bateryy operated instrument for test-

ing and troubleshooting electrical and electronic systems. If the meter is dam-

aged or something is missing, contact the place of purchase immediately.

AWARNING identifies conditions and actions that pose hazard(s) to the user; a

CAUTION identifies and actions that may damage the Meter.InternTIONl electri-
