6.The min. input voltage is 50 V and the min. input
current is 2A; if active power value is smaller than
this limit, “0.00 kW” will be displayed in stead of
active power value.
7. Press SET button to display AUTO, and press
▲/▼
button to set measurement range for voltage and
current; press SET button to return.
8. Press down I button, current value, current peak
value and frequency will be displayed on bottom line
of LCD.
9. Press down U button, voltage value, voltage peak
value and frequency will be displayed on bottom line
of LCD.
10.Press REC/SAVE button to show MAX and MIN
Passive power is a value not directly measured;
equation for kVAr is kVAr2=kVA2-kW2; its value is
calculated by software based on the measured
voltage, current and active power, and displayed
on LCD.

cosΦ, sinΦ, and phase angle measurement
1.
Switch the function-switch knob to Φ (1 phase)
position, and the test wire is inserted to V1/V2 input
terminals.
2.The meter will automatically measure and display
power factor, voltage value and current value.
3.Press WATT
button to display phase angle, power
factor (cos Φ), and sinΦ
;
negative power factor
signifies that the load being tested is a load with
capacitor characteristics.
4.Press down I button, current value, current peak
value and frequency will be displayed on bottom
line of LCD.
5.Press down U button, voltage value, voltage peak value
and frequency will be displayed on bottom line of LCD.
6.Press REC/SAVE button to show MAX and MIN
7.Press SET button to display AUTO, and press /
button to set measurement range for voltage and
current; press SET button to return.
8.After measuring, press HOLD button to keep showing
the data on LCD, and press REC/SAVE button to
display the saved serial number, and then press SET
button to confirm it and return.
Single-phase three-line circuit
the process for measuring power and power factor for
single-phase three-line circuit is the same as that for
single-phase two-line circuit, where the black clip is
connected to the middle wire, and the red clip and
clamp-type sensor are simultaneously connected to all
test wires.
