A. Product Overview
The HIOKI P2010 is a DC high voltage probe designed for professional electrical testing applications. It enables compatible HIOKI clamp meters and digital multimeters to measure high DC voltages up to 2000 V.
The probe is particularly useful in modern solar photovoltaic installations, where DC system voltages can be significantly higher than the direct measurement range of standard measuring instruments.
The P2010 is designed for professional technicians who need to carry out high voltage testing, commissioning, maintenance and troubleshooting work.
Key Features
• DC voltage measurement up to 2000 V
• CAT III 2000 V measurement capability
• Designed for solar PV high voltage applications
• Compatible with selected HIOKI clamp meters and digital multimeters
• Suitable for electrical inspection and maintenance
• Professional accessory for high voltage DC measurement
• Useful for solar installation testing and troubleshooting
B. Working Principle
The HIOKI P2010 works by reducing the high input DC voltage to a level that can be safely measured by a compatible HIOKI measuring instrument.
The probe is connected between the electrical circuit being tested and the compatible clamp meter or digital multimeter.
When a high DC voltage is applied to the probe, the internal circuitry scales the voltage before passing the measurement signal to the connected instrument.
The connected HIOKI instrument then displays the corresponding high voltage reading.
This allows technicians to measure voltages up to 2000 V DC without directly applying the full high voltage to the meter input.
C. Why HIOKI P2010 Is Used
The HIOKI P2010 is used when the DC voltage in an electrical system exceeds the normal measurement capability of a standard multimeter or clamp meter.
It is especially important in solar PV installations where series connected solar panels can generate very high DC voltages.
Using the P2010 allows technicians to perform high voltage measurements with compatible HIOKI instruments while maintaining an appropriate measurement configuration for high voltage work.
It can be used for:
• Solar PV string voltage measurement
