Press SELECT to choose the first phase
z
The triple displays shows the first phase value of frequency
z
Then press SELECT again to choose the second phase
z
The triple displays shows the second phase value of Frequency Hz AC Voltage V and AC Current A.
z
Press SELECT again to choose the third phase
z
The triple displays shows the third phase value of Frequency
z
10. When measuring 3 phase 3 wires:
The first phase and second phase operating method is same as three phase 4 wires.
z
Jump over the third phase measurement.

11. MAX/▲ and MIN/▼ are not valid at this measurement mode.
Note
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.

G. Active Energy (main display) + Active Power (left secondary display) + Time (right secondary display) Measurement
Warning
To avoid damages to the Meter or harms to you, do you measure higher than AC voltage 600V rms and AC current 1000A rms.
To test for Active Energy (main display) + Active Power (left secondary display) + Time (right secondary display), connect the Meter as follows:
8. Press the MENU to select Active Energy (main display) + Active Power (left secondary display) + Time (right secondary display) range.
9. Press the lever to open the transformer jaw, and clamp them to the corrresponding phase of tested conductor. If user needs to mesaure any phase of the 3 phase, then
clamp them to that phase's conductor.
10. The connecting method of 3 phases 4 wires, 3 phases 3 wires or single phase 2 wires, see figure 4, 5 and 6
11. Press SELECT to choose one of the three phases (
z The double display shows the value of tested object's active engergy kWh value and the measuring time of the corresponding phase.
The measuring reading gets increasing along with the time increases. Press HOLD to read a particular time kWh value. Then the reading and time are locked,
z
but still continuous accumulate measuring time.
After read the data, press HOLD again to continous measurement. kWh value continous accumulate and the measuring time jumps to the present measuring time.
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.
z
12. MAX/▲ and MIN/▼ are not valid at this measurement mode..
13. Press CLEAR to reset the time.
14. USB interface feature is not valid at this measurement mode.
Note
When there is no input signal, it cannot carry out active energy measurement.
z
When there is input signal, the maximum waiting time is around 10s before timing.
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.
