Note
When measuring AC current range, It may have unstable or wrong sensed readings,
it will not affect measurement result.
Change to AC:
Couple AC and True RMS response method. Input sine wave to adjust. Non sine
wave must follow the below data to adjust:
Peak factor: 1.4~2.0, add 1.0% on the stated accuracy.
Peak factor: 2.0~2.5, add 2.5% on the stated accuracy
Peak factor: 2.5~3.0, add 4.0% on the stated accuracy.
When current measurement has been completed, disconnect the connection
between the conductor under test and the jaw, and remove the conductor away
from the transformer jaw of the Meter.
the transformer jaw, otherwise it will casue deviation. The Meter can only measure
one conductor at a time, to meausre more than one condutor at a time will cause
deviation.
When the measuring current >1A, press
Hz
button to toggle between AC current
and frequency measurement mode. But the frequency readings obtained from
this range is only for reference.
