Rules

For

Safe Operation

. .warning

To avoid possible electric shock

or

personal

injury

,

and

to

avoid possible damage to the Meter or to the equipment

under test, adhere to the following rules:

Before using the Meter inspec t the case. Do not use the

Meter

if it is damaged or the case

(or part of

the case) is

removed. Look for cracks

or

missing plastic. Pa y

attention to the insulation around the connectors.

Inspect the test leads for damaged insulation or exposed

metal. Check the test leads for continuity. Replace

damaged

test leads with identical model number

or

electrical specifications before using the

Meter.

Do

not apply more than the rated voltage, as marked on

the Meter, between the terminals or between any

terminal and grounding.

The rotary switch should be placed in the right position

and

no any changeover

of

range shall be made

during

measurement

is conducted to

prevent damage

of the

Meter.

When the Meter working at an effective voltage over 60V

in DC or 30V

rms

in AC, special

care

should be

taken

for

-

there

is

danger of

electric shock.

Use the proper terminals, function, and

range

for your

measurements.

Do

not use or store the Meter in an environment of high

temperature,

humidit

y, explosive, inflammable and

strong magnetic field . The performance of the

Meter

may deteriorate after dampened.

When using the test leads, keep your fingers behind the

finger guards.

Disconnect circuit power

and

discharge all high-voltage

capacitors

before testing resistance, continuity, diodes,

current,

or capacitance.

Before measuring current, check the Meter's

fu

ses and

turn off power to the circuit before connecting the

Meter

to the circuit.

Replace the battery as soon as the

battery

indicator

11

Q

1

appears. With a low battery, the Meter might

produc

e

false readings that can lead to electric shock and

personal injury.

Remove test lead, t.

emperature probe

, RS232C interface

5


5/18

cable

and

test clip from the Me

ter and turn the Meter

power off before opening the Meter case.

When

servicing

the Meter

, use only

the same

model

number

or identical electrical specifications replacement

parts.

The internal circuit of the Meter

shall

not

be

altered

at

will to avoid

damage of

the

Met

er

and

any accident.

oft cloth

and

mild detergent shonld be used to clean the

surface of the Meter

when servicing. No

abrasive and

solvent should be used to prevent the surface

of

the Meter

from corrosion

damage and

accident.

The

Meter is suitable for indoor use.

Under the environment

with high +/-4kV) electrostatic

discharge

,

the

Me

ter ma

y

not

be

operated as normal

condition.

The user ma

y

require resetting the Meter.

Please take out the

batter

y when it is not being used for a

prolonged period to avoid damages to

the

Meter.

Please constantly check the battery as it may leak when it

has been using for some time, replace the battery as soon

as leaking appears. A leaking battery will

damag

e the Meter.

Being

in

the right measurement range is important:

If the range is too low for the input, the Meter display O to
