Brief: We tested it—see the highlights and what to expect in real operation. This video demonstrates the ZX-3125A Electronic High Voltage Digital Insulation Resistance Tester in action, showcasing its 5KV testing capabilities. Watch as we explore its key features, including auto-discharge, backlight function, and safety warnings, providing valuable insights for professionals in electrical testing and maintenance.
Related Product Features:
  • Meets IEC 61010-1,-2-30 and IEC 61010-031 safety standards for hand-held probes.
  • Features an auto-discharge function that safely discharges capacitive loads after measurement.
  • Includes a backlight for clear visibility in dimly lit locations or during nighttime work.
  • Provides audible and visible LIVE circuit warnings for enhanced operator safety.
  • Automatically calculates and displays PI (Polarization Index) and DAR (Dielectric Absorption Ratio).
  • Offers auto-power off function to conserve battery after 10 minutes of inactivity.
  • Capable of insulation resistance testing with rated voltages from 250V to 5000V.
  • Includes voltage monitoring to check discharge status of equipment under test.
Faqs:
  • What safety standards does the ZX-3125A insulation resistance tester comply with?
    The ZX-3125A is designed to meet IEC 61010-1,-2-30 (CAT III 600V/CAT IV 300V Pollution degree 2) and IEC 61010-031 requirements for hand-held probes.
  • How does the auto-discharge function work on this tester?
    When measuring insulation resistance on capacitive loads, the tester automatically discharges stored electric charges after measurement. The discharge status can be monitored using the voltage display.
  • What measurement capabilities does this insulation resistance tester offer?
    The ZX-3125A provides insulation resistance testing at multiple voltage levels (250V, 500V, 1000V, 2500V, 5000V) and can automatically measure and display PI (Polarization Index) and DAR (Dielectric Absorption Ratio).
  • How long can the ZX-3125A operate on a single charge?
    The tester can measure for up to 25 hours under a load of 100MΩ on the 5000V insulation resistance range.
