RCD parameter meter PZO-510

The device is designed to test residual current devices (RCDs) of AC, A, B types. The RCD type and its rated differential current are set manually in the device. All types of RCDs that do not have an operational amplifier with threshold values can be checked using the device offline, for example, when buying, without connecting voltage to the mains. There is a function for measuring the resistance of the phase-zero loop from 0.4 to 60 ohms. PZO-510 is equipped with magnetic holders, which allows, if necessary, to quickly mount the device on steel surfaces, including those with paint and varnish coatings. 

The instrument is powered by a NI-MH 6 V 2A/H battery or five 1.5 V AA batteries.

Operating temperature range from -15 to +55 0C.

Calibration interval 2 years

Functionality:

• measurement of trip current RCD type AC, A, B (10, 30, 100, 300, 500 mA) with the ability to set the initial current phase, current phase delay angle, current polarity, constant component;
• measurement of RCD disconnection time type AC, A, B;
• measurement of the effective value of the alternating current voltage simultaneously along the circuits (L-N, L-PE, N-PE);
• measurement of RCD parameters in offline mode in the absence of a 220 V network;
• measurement of RCD parameters according to a predetermined test program;
• measurement of the active resistance of the "phase-zero" loop;
• communication with PC Bluetooth, memory for 10,000 measurements.
