Operation
The MCPP230 will execute the following tests:
- VOLT and Socket Test (Correct wiring of Plug)
- Voltage measurement L-N , TRMS
- Residual Current (RCD) type A, AC and F also in AUTO mode with TOUCH VOLTAGE measurement
- Z LOOP (Earth resistance with touch voltage and impedance Zs (ZL-Pe) with prospective earth fault current)
- Short circuit current
- Voltage harmonics up to 49th
- THD% (Total harmonics distortion)
- Frequency of the fundamental Harmonics and up to 49th
Function can be selected through the dedicated FUNC button.
Sub-function features can be selected through the F1 and F2 buttons, for example for selecting the RCD type or evaluate different harmonics.
The instrument is powered from the line and due to the supercap technology can keep the power even when disconnected from the line. Fully charged, the supercap will allow ~45 seconds of use after switch off from the line. This allows the user to read the value after the RCD has tripped (with tripping time) or when it is difficult to read the display value.
Test results display GREEN when the measured value is correct in accordance with the local limitations or RED when the test has failed. In a failed SOCKET TEST, an alarm sounds.
Volt and socket test
This feature measures Voltage between phase and neutral and test the socket wiring in accordance to local requirement.
Operation
- Plug the instruments into the socket and press the FUNC button to select the Voltage function.
- Voltage between Phase and Neutral will be shown on the display
- If socket is correctly wired and touch voltage is <50 V (Fig 1). A green bar indicates every parameter is correct.
- If an error is detected due to the incorrect wiring, A red bar and alarm sound indicates an error with a code to explain (Fig 2 and 3).
- Frequency can be shown through F2 button.
| Code displayed | Wiring error
(bar is Red and sound alarm) |
Solution |
| L-N | Phase – Neutral Reverse | Adjust the socket wiring |
| L-N | Phase – Earth Reverse | Adjust the socket wiring |
| L-PE | Open Neutral | Connect Neutral wire |
| NO PE | No Earth | Check Earth connection |
| VT >50V | Touch Voltage >50V | Dangerous Voltage on Earth |
RCD (residual current device)

- RCD Tripping Time is shown on the display in ms for every STEP.
-
- Passed trip time results are displayed in GREEN (Fig 6).
- Failed trip times will be displayed in red (Fig 7) and the test will be stopped.
-
LOOP
The measurement is performed according to IEC/EN61557-3.
Loop test measures the impedance between Phase and Earth/Ground without a RCD trip.
Test modes

- Z: Global Earth Resistance
- VT: Touch Voltage
NOTE : Limit for earth ground resistance is defined as:
Impedance measurement Zs L-pe in TNS system
- Z: Fault Earth Impedance L-Pe
