4. PRECAUTIONS & PREPARATIONS FOR
MEASUREMENT
1) Ensure that the DC 9V battery is connected correctly to
its snap terminal and placed into the battery compartment.
2) Select the correct position of " Function Switch " &
" AC/DC Switch " before making measurements.
3) Place the RED Test Lead into the proper input terminal
before making measurements.
4) When make measurement, selecting the proper
measurement range by starting at the largest anticipated
value and progressively selecting lower ranges the
measurement falls within the proper range.
5) Remove either of the test leads from the circuit under
test when changing the measurement range.
6) Operate the instrument only in the ambient temperature
range of 32 - 122
蚌
(0 -50
蚓
) and less than 80 %
relative humidity.
7) Do not exceed the maximum rated voltage of each range
and input terminal.
8) Slide the " Power ON/OFbF" always to the " OFF" position
when the instrument does not use. Remove the battery if
the instrument intend not be used for a long period of time.
5. MEASURING PROCEDURE
5-1 Voltage Measurement
1) Connect red test lead to "V" input terminal and black test
lead to " COM" input terminal.
2) A. If voltage to be measured is AC, select " AC/DC
Switch" to the "AC" position.
B. If voltage to be measured is DC, select " AC/DC
Switch" to the "DC" position.
