Voltage detectors – Part 3: Two-pole low-voltage type". Therefore, the CPOL3 must not be used to check if voltage is present. The CPOL3 is designed to check a series of test points for correct polarity and for wiring errors. The checks can be performed on current and voltage transformers as well as on the connected cables and terminals. -

A: measured current in amperes Polarity indicator Polarity is OK. If the CPOL3 detects a polarity check signal with the same polarity as the source signal, it shows a happy green face. Polarity is not OK (inverted polarity). If the CPOL3 detects a polarity check signal that has an inverted polarity compared to the source signal, it shows a sad red face. - Page 16 If the test set in use supports generating a polarity check signal with embedded phase ID information, the CPOL3 will try to decode the phase ID and display a number of red or green dots, corresponding to the phase number.

Page 20: Measuring Settings
Press the Select button to cycle through the measuring settings. Example: Test set Basically, the CPOL3 always measures the voltage on the terminal (1). To measure currents, you need to use a current-clamp (2) together with the CPOL3. Then, a configurable conversion factor is applied so that the CPOL3 displays the result directly as current value in amperes. - Page 21 Input impedance The CPOL3 has 2 input impedance modes: HiZ (high input impedance) and LoZ (low input impedance). In the LoZ mode, the input impedance is ~3 kΩ instead of 1.8 MΩ in the regular HiZ mode.

Page 22: Test Modes
Polarity detection If the CPOL3 detects a CPOL polarity check signal, it shows a green happy or red sad face to indicate the correct or wrong polarity. If the phase ID information of the CPOL polarity check signal is detected, it is displayed next to the face as a number of dots. -
Page 23: Oscilloscope
Operation 4.3.2 Oscilloscope In the Oscilloscope test mode, the CPOL3 displays the waveform of the measured signal. You can use it to check the signal waveform if no polarity signal can be detected in the Meter test mode. RMS value Shows the RMS value of the measured signal (True RMS, including DC component). -
Page 24: Spectrum
User Manual 4.3.3 Spectrum In the Spectrum test mode, the CPOL3 displays the spectrum of the measured signal. This can be useful, for example, to check if the 52.6 Hz test signal is distorted by coupled 50 Hz or 60 Hz mains components. - Page 25 DC component is shown. u Press the Hold button to freeze the display. u Press and hold the Hold button for a few seconds to enable Peak hold.

(A, solid line) or the secondary side (B, dashed line) of the CT, depending on the test set in use. If the CPOL3 detects a steep rising slope followed by a slowly falling slope, it indicates a correct polarity with a happy green face (1). If the polarity is reversed, for example, due to a wiring error, the slope rises slowly and is followed by a fast falling slope. -
Page 31: Phase Identification
CPOL3 can decode the phase ID. It displays the phase number as a number of dots next to the green or red face showing the polarity (4). If the CPOL3 cannot decode the phase ID information, it only shows the green or red face for positive or negative polarity. - Page 32 In this case, we recommend using 0° between the phases for the injection. Then, the currents on the common return wire will sum up ,and you can measure them. The CPOL3 will display a polarity check signal with the correct polarity but without phase ID on the common return wire.
