5-3 AC Watt Hour ( Whr ) Measurement
All the measuring procedures are same as the above " 5-1
AC Watt/V/A/PF/Hz Measurement " except should push the
" WATT/VA/Whr Button " ( 3-7, Fig. 1 ) twice, then the
display will show the Whr value along with the elapsed time.
*
The Whr ( Watt Hour ) is the value of Watt x hour.
*
The Whr measurement will start at the moment after the " Whr " unit
is displayed on the LCD display.
*
The display of Whr measurement will stop ( hold ) when push the "
Data Hold Button " ( 3-5, Fig. 1 ) once. Push the " Data Hold Button
" once again will continue the Whr function.
*
Press " Whr Zero Button " ( 3-8, Fig. 1 ) once will " reset ( zero ) "
the Whr measuring value and make the new measurement again.
5-4 AC Voltage, AC Current Measurement
1) Push the " Power switch " ( 3-2, Fig. 1 ) to " On " position.
On = 1, Off = 0
2) Select the " AC V/A/WATT Switch " ( 3-3, Fig. 1 ).
3) Select the " Current In Select Switch " ( 3-6, Fig. 1 ) to
the " DIRECT " position.
4)
AC Voltage measurement
a. Connect red test lead to " V/Ohm Terminal " ( 3-17,
Fig. 1 ) and black test lead to " COM Terminal "
( 3-18, Fig. 1 ).
b. Connect test lead probes into circuit under test.
c. The display will show the AC voltage directly.
5)
AC Current measurement
a. Connect red test lead to " Current ( 10 A ) Terminal "
( 3-19, Fig. 1 ) and black test lead to " COM Terminal "
( 3-18, Fig. 1 ).
b. Open the circuit in which current is to be measured.
Now securely connect test leads in series with the load
which the current is be measured.
c. The display will show the AC current directly.
* The max. AC current input value should less than 10 A.
