4. PRECAUTIONS & PREPARATIONS FOR
MEASUREMENT
1) Ensure that the batteries is connected correctly to its snap
terminal and placed in the battery compartment.
2) Select & push the correct Switch & button before marking
measurements
3) Place the Test Lead into the proper input terminal before
markingmeasurements.
4) Remove either of the test leads from the circuit under
test while changingthe measurement function.
5) Operate the instrument only in the ambient temperature
range of 32 - 122 ( 0 - 50 ) and less than 80%
Relative humidity.
6) Do not exceed the maximum rated voltage of each range
and input terminal.
7) Always switch the power to its " Off " position when the
instrument is not in use. Remove the batteries if not intend
to use the instrument for a longperiod of time.
5. MEASURING PROCEDURE
Caution
:
* Do not apply the
overload volta

AC Watt/V/A/PF/Hz Measurement
1) Push the " Power switch " ( 3-2, Fi
g
. 1 ) to " On " position.
On = 1, Off = 0
2) Select the " AC V/A/WATT Switch " ( 3-3, Fi
g
. 1).
3) Select the " Current In Switch " ( 3-6, Fi

Remark
:
* The " Watt zero Button " can be executed only unde
r
ACV & ACA are under zero condition ( no si
g
nal input ).
5) Power off the " Power Source " of the measured
installation.
