Safety Information

T his Me er compliest with EN 61010-1:2010 fety sa measurement

requirement:Pollution Degree 2, measurement

category CAT III 600V and Double Insulation.

CAT II (measurement category): Test and measuring

circuits connected directly to utilization points (socket outlets

and similar points) of the low-voltage MAINS installation.

Use the Meter only as specified in this operating manual,

otherwise the protection provided by the Meter may be

impaired.

Danger identifies conditions and actions that pos e

hazard(s) to the user.

Warning alerts users to avoid electric shock.

Caution identifies conditions and actions that ma y

damage the Meter and affect accurate

measurement.

Danger

Use of instrument in a manual not specifed by th e

manufactuer may impair safety features/protection

prov ed by the e nt. d the f gid quipme Rea ollowin

sa rma care refety info tion full foy be us oring

servicing the instrument.

Do not apply more than 600V.

Do not use the Meter around explosive gas,

vapor or dust.

Do not use the Meter in a wet environment.

When using the test leads, keep your figure s

away from the lead contacts. Keep your

figures behind the finger guards on the leads .

Do t u the th any p or co rno se Meter wi arts ve

removed.

Operating Caution identifies conditions that user

needs to t ake ex rat care during opera ting the Meter

Warning

Do not use the Meter if it is damaged or metal

part is exposed. Look for cracks or missing

plastic.

Be careful when working above 33V rms, 46.7 V

ac rms or 70V DC. Such voltages pose a shock

hazard.

Discharge all loading of circuit under test afte r

measuring high voltage.

When carrying out insulation measurement,

do not contact the circuit under test.

Caution

When performing resistance tests, remove all

power from the circuit to be measured and

discharge all the power.

Wh ing then icserv e Meter, u y se onl only the

test leads and power adaptor with the same

model number or identical electrical

specifications.

Do not use the Meter if the battery indicator

( ) a shows battery empty condition. Take

the battery out from the Meter if it is not use d

for a long time.

Do not use or store the Meter in an

environment of high temperature, humidity,

explosive, inflammable and strong magnetic

field. The performance of the Meter may

deteriorate after dampened.

So c th a m dft lo nd ild etergent s be u dhould se

to clean the surface of the Meter when

servicing. No abrasive and solvent should be

u d to p nt the su of the omse reve rface Meter fr

corrosion, damage and accident.

Dry the Meter before storing if it is wet.

International Electrical Symbols

International symbols on the Meter and in this manual

are explained in Table 2.

Table 2. International Electrical Symbols

Battery Saver (Sleep Mode)

The Meter enters the Sleep Mode and blanks the displa y

if there is no button press for 15 minutes. This is don e

to conserve battery powe The Meter comes out r. of

Sleep Mode whe button is pressed and hol n ON/OFF d

for 1 second.

Battery Indication

There is a battery indicator shown on the upper left corner

of the display. Please refer to Table 3 for detailed

explanation.

Battery Voltage

5.9V ~ 10.6V. It means the battery is

empty, Do not use the Meter as it

cannot

guarantee accuracy.

10.7V ~ 11.1V. It means the battery is

almost empty, replacing battery is

necessary. At this status, the Meter can

still output 500V and 1000V to measure,

the measured accuracy will not be

affected.

11.2V ~ 12.2V

12.2V or more

structure and description

Do not change battery when the Meter is in

wet environment.

Place test leads in proper input terminals.

Make sure all the test leads are firmly

connected to the Meter's input terminals.

Make sure the Meter is turned off when

opening the battery compartment.
