such

as

square wave, triangle wave and

staircase wave, such measurements are accurate.

3.2.2 Measuring resistance

&.

In order to avoid any damage to instrument or

measured equipment, before measuring resistance, cut

off

all power supplies

of

the circuit being measured and fully

discharge all high-voltage capacitors.

The

unit

of

resistance

is

Use·

the test pen

to

measure the resistance

of

the circuit

to

be

tested.

4.

Read

the measured resistance from the

LCD

display.

Note:

(1)

Resistance measured on .the circuit

is

usually different

from the rated value

of

resistance.

(2)

During measurement

of

low resistance, in order

to

guarantee accuracy, first short circuit

two

pens and read

the resistance

for

pen short circuit, and

it

is

required

to

reduce

such

resistance after measuring the resistance.

(3)

In 60Mn, reading could

be

stable only after several

seconds. This

is

normal

to

high resistance measurement.

(4) When the instrument

is

of

open circuit, the display will

indicator 'OL", indicating the measured value exceeds the

range.

current

range

s

of

the

instrument

are namely 600µA,

6000µA, 60.00mA, 600.0mA, 6.000A

and

10

The

AC

current

ranges

are namely 600µA, 6000µA, 60.00mA,

600.0mA, 6.000A

and

10.00A;

Measure current:

1. Turn

the

rotary switch

detected

signal

strength

, meanwhile

the

buzzer

will

make alarm

sounds

of

different frequencies.

Note:

1. Even

if

there

's

no

indication,

voltage

may still exist. Do

not

judge

whether

there's

voltage
