Apparent Power + Ac Voltage + Ac Current Measurement; Reactive Power + Ac Voltage + Ac Current Measurement - ADInstruments AD233 Manual De Usuario

Modelo AD233: MANUAL DE USUARIO
Press SELECT to display the 3 phase sum of watt value (sum of power factor + sum of active power + sum of reactive power) as figure 14
z
.
The maximum power is 600kW of single phase active power, OL will be displayed when it is over than that. The maximum range is 1800kW of three phase sum of active
14.
power and reactive power, OL will be displayed when it is over than that.
Press MAX/▲, the display shows MAX, it starts recording the maximum active power value, voltage value and current value. Press again to display the current active
15.
power value, voltage value and current value.
16. Press MIN/▼, the display shows MIN, it starts recording the minimum active power value, voltage value and current value. Press again to display the current active power
value, voltage value and current value.
Note
When there is no input or single phase, the Meter displays OL.
z
It can only sum up and save the current measurement value. The maximum and minimum value cannot sum up and save.
z
Only at this range can carry out sum of watts measurement, other ranges cannot carry out this measurement.
z
USB interface connection is invalid when carrying out sum of watt 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.

B. Apparent Power (main display) + AC Voltage (left secondary display) + AC Current (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 Apparent Power (main display) + AC Voltage (left secondary display) + AC Current (right secondary display), connect the Meter as follows:
9. Press the MENU to select Apparent Power (main display) + AC Voltage (left secondary display) + AC Current (right secondary display) range.
10. 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.
11. The connecting method of 3 phases 4 wires, 3 phases 3 wires or single phase 2 wires, see figure 4, 5 and 6
12. When measuring 3 phase 4 wires:
Press SELECT to choose the first phase Ø 1, see figure 15.
z
The triple displays shows the first phase value of apparent power kVA, AC voltage V and AC current A..
z
Then press SELECT again to choose the second phase Ø 2, see figure 16.
z
The triple displays shows the second phase value of apparent power kVA, AC voltage V and AC current A.
z
Press SELECT again to choose the third phase Ø 3, see figure 17.
z
The triple displays shows the third phase value of apparent power kVA, AC voltage V and AC current A.
z
13. 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.
z
14. The maximum measuring range is 600kW when measuring single phase apparent power kVA, OL wil be displayed when it is over than that.
15. Press MAX/▲, the display shows MAX, it starts recording the maximum apparent power value, AC voltage value and AC current value. Press again to display the current
apparent power value, AC voltage value and AC current value.
16. Press MIN/▼, the display shows MIN, it starts recording the minimum apparent power value, AC voltage value and AC current value. Press again to display the current
apparent power value, AC voltage value and AC current value.
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.

C. Reactive Power (main display) + AC Voltage (left secondary display) + AC Current (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 Reactive Power (main display) + AC Voltage (left secondary display) + AC Current (right secondary display), connect the Meter as follows:
button is not valid.
