4-2 Power supply from the battery

1)

Install the  " DC3V battery ( CR-2032 ) x 2 PCs "
into the " Battery compartment " ( 3-12, Fig. 1) 

2)

Slide the " Power type switch " to the " B " position (
battery position ), the meter will offer the power
source from the battery.

5. MEASURING PROCEDURE

5-1 precautions & preparations  for measurement

1) Place the Red & Black Test Leads into

the proper input terminal  before
making measurement.

2) Remove either of the test leads from

the circuit when changing the
measurement range.

3) Do not exceed the maximum rated voltage

to the input  terminal.

4) Do not exceed the maximum rated 

current to " Current sensing Jaws.

5) For safety consideration, when change

the new test leads, it should use the
replace approval test leads.

5-2 Power management

1) Pressing the  " Power On button " ( 3-4, Fig. 1 ) once,

the meter will be power On.
Pressing the  " Power On button " ( 3-4, Fig. 1 ) once
again, the meter will be power Off..

2) The meter will be power Off automatically within 

10 minutes after power On.
