z When the measuring time is over 24 hours or the
Meter is switched to other measuring ranges, active
energy measuring will stop.
z The maximum readinng of acitve energy is
9999kWh. OL will be displayed when the reading is
over than that.
5. MAXMIN are not valid when measuring active
energy.
6. Press CLEAR and hold for 1 seconds to reset the
time and energy.
Note
z When there is no input signal, it cannot carry out
active energy measurement.
z When testing has been completed, disconnect the
connection between the testing leads and the circuit
under test and remove testing leads from the input
terminals.
True RMS Measurement and Average
Value Measurement
The True RMS measurement method can
measure accurately the effective value of non-sine
wave input signal.
Average value measurement method can
measure the mean value of one sine wave input signal,
and then displays it as RMS value
When the input waveform has distortion, measuring
tolerance will be included. The total tolerance depends
on the total distortion. Below table 1 shows the
waveform coefficient and the relationship and the
requested changing factor of sine wave, square wave,
