Highlights

The Hioki IR4053 features a photovoltaic resistance function for measuring solar power systems, allowing you to measure insulation resistance accurately without shorting strings of photovoltaic cells and without risking accidents such as arc discharge events, even as the system continues to generate electricity during daylight hours.


Key Features:

  • Safely and accurately measure PV insulation resistance even while generating solar power.
  • Built-in PV dedicated function, display measurements in 4 seconds.
  • Five ranges (50/125/250/500/1000V) built in for normal insulation resistance measurement.
  • Built-in 1000 VDC voltage measurement for open voltage tests of PV systems that support 1000V.
  • Built-in comparator function.
  • Drop proof design withstands drop onto concrete from a height of 1 meter.
  • DC voltage range: 4.2 V (0.001 V resolution) to 1000 V (1 V resolution), 4 ranges, Accuracy: ±1.3% rdg. ±4 dgt., (Ranges in excess of 1000 V are not guaranteed for accuracy.)
  • AC voltage range: 420 V (0.1 V resolution)/600 V (1 V resolution), 2 ranges, 50/60 Hz, Accuracy: ±2.3% rdg. ±8 dgt., (Ranges in excess of 600 V are not guaranteed for accuracy.)
  • Display: Semi-transmissive FSTN LCD with back lighting, Backlight.
  • Response time: Insulation resistance range: 1 second, PVΩ function: 4 seconds (based on in-house tests).
  • Other functions: Live circuit indicator, automatic electric discharge, automatic DC/AC detection, comparator, drop proof, auto power save.

What are the problems with conventional insulation testers?

Problems with conventional insulation testers and the 2 measurement methods determined by recognized guidelines:


Measurement that does not involve a short-circuit

This is not as dangerous, but depending on the circuit status, the measurement may be affected by the generating PV and may produce a result different from the actual insulation resistance.


Measurement that involve a short-circuit

To accurately measure a generating PV, one needs to short the measured circuit, which requires that a short-circuit switch be separately installed. Short-circuiting will also pose the danger of creating an arc. In addition, to minimize hazards, it is recommended that the testing be conducted at night.


What's Included In This Package:

  • 1x Test Lead (L9787)
  • 1x Neck strap
  • 1x Instruction manual
  • 4x AA alkaline batteries (LR6)
 


Measurement not affected by generating PV

The IR4053, which was designed for PV, can accurately measure insulation resistance without being affected by the generating PV.


Accurate and safe measurement without creating shorts

Normally, to accurately measure the insulation resistance of a generating PV, one needs to short the measured circuit. With the IR4053's PV measurement mode, short-circuiting is not necessary.


Displays measurement in 4 seconds

The IR4053 displays the measured value just 4 seconds after starting measurement. After the first display, the displayed value is updated each second. Comfortably carry out swift measurements.


Comparator function/ Red light

You can compare measurements to any set values. If the result does not meet the set value, the red light will warn of nonconformance.


Test lead with remote switch

This allows you to apply output voltage with the switch in your hand, work with a light, and see the result of the comparator with an LED.


Drop proof

The sturdy design will not break even if dropped onto concrete from 1 m, so you can use it with peace of mind.
