and continue to measure, Active Energy value still add up.
Active energy measurement don’t stop until select other
measurement function.
c. The
MAX
button and
MIN
button is invalid in
Active Energy measurement mode.
d. The maximum value of Active Energy is “9999kWh”. If
Active Energy value exceeds the maximum value , the
display will show “OL” symbol.
e. Active energy measurement is viable in single-phase
circuit because you only measure current of one phase at
one time, so you can not measure three-phase Active
Energy. If you need measure Active Energy for long
during measurement, you are suggested that you can use
EX- P function, the meter will work no using the battery
but test voltage signal as power supply.
NOTE: When you turn the selector to EX- P to measure voltage or
power parameter, the input voltage of V1 jack must less than 250V,
otherwise the fuse will be blown.
Measuring Three –Phase Four-Wire Circuit
Three-phase power parameter means total Active Power, total
Reactive Power, total Apparent Power, total Power Factor. The
clamp meter can not measure three-phase Active Energy. The
measurement method of three-phase power parameter is that
you measure power parameter of each phase conductor
respectively at first, then calculate three-phase power
parameter in the meter. For a balance load, the measured data
is accurate, if power parameter fluctuates larger, then the error
of total power parameter increases more.
