VII. Operation Instructions
Press the ON/OFF button; turn the measure range switch to choose the
correct testing parameters and range.
1. Measuring AC voltage
Turn the rotary switch to 500V in U1 region, and connect the measured
voltage into jack U1, you can measure. If the measured value is less than 200V,
you can directly turn the switch to 200V in U1 region to obtain better
measurement accuracy.
The two channels U1, U2 are provided with the same voltage test function,
so you can make the measurement through channel U2. Detailed methods
please refer to the operation of U1.
2. Measuring AC current
Turn the rotary switch to 10A in I1 region, and connect the down-lead of the
clamp-current transformer into jack I1, then clamp the measured circuit with
clamp jaw, you can measure. If the measured current is less than 2A, you can
directly turn the switch to 2A in I1 region to obtain better measurement
accuracy.
The two jacks I1, I2 are provided with the same current test function, so
you can make the measurement through jack U2. Detailed methods please
refer to the operation of I1.
3. Measuring phase angle between two voltages
When measuring the phase angle that U2 lags U1, turn the rotary switch to
parameter U1U2.Under measurement, you can turn the rotary switch clockwise
to different measure ranges in U1 region to measure input voltage U1, or turn
the rotary switch anticlockwise to different measure ranges in U2 region to
measure input voltage U2.
Note: When measuring phase, the marks U1, U2 around voltage input
jacks and the red "*" mark on clamp-current transformer are phases with the
same name end.
