4. PRECAUTIONS & PREPARATIONS FOR

MEASUREMENT

1)

Ensure that the DC 9 V ( 006P, MIN1604 ) batteries are connected

with the right polarity and placed in the battery compartment
correctly.

2) Place the Red & Black Test Leads into the proper input

terminal before making measurement.

3)

Remove either of the test leads from the circuit when

changing the measurement range.

4)

Except operate the " Data Hold " function, it should

cancel the " Data Hold " function, otherwise the display

reading will freeze permanently.

5) Do not exceed the maximum rated voltage and current to

the input terminal.

6) Always switching the " Function Rotary Switch " to the

" Off " position when the instrument is not operation.

7)

Remove the battery if the instrument is not to be used in

a long period of time.

8)

For safety consideration, when change the new test

leads, it should use the replace test leads that already

approval of " CATIII-1000 V " at least.

9)

Power On/Off management :

a.

When not use the meter, should rotate the " Function rotary

switch " ( 3-10, Fig. 1 ) to the " OFF " position.

b.

During the measurement, after 10 minutes the meter

will auto power off. If intend to power on again, it

should rotate the " Function switch " to " OFF "

position then set to the new desiring function position.

c.

Disabling auto power off ( not auto power off )

Press the " TIME button " ( 3-3, Fig. 1 ) into

the setting mode,the Poff set " no "

auto power off function can be lifted.
