Expert FAQ: Insulation Resistance Testing

Q1: What is the difference between insulation resistance and dielectric strength?

Insulation resistance measures how well insulation impedes DC current, expressed in megaohms (MΩ), under steady voltage; dielectric strength (as used in hipot testing) determines the maximum voltage insulation can withstand instantly without breakdown.

Q2: Why are gold-plated terminals used in high voltage testers?

Gold-plated contacts resist oxidation and corrosion, ensuring low contact resistance and signal consistency, which are critical for reliable high-resistance readings in hostile environments.

Q3: What does "±2% full scale" accuracy mean?

It means any measured value could have an error of up to 2% of the device's maximum display range—ensuring industrial-grade measurement confidence especially above GΩ.

Q4: How long is the PS-3045 rated operating life and what affects it most?

The PS-3045 is designed for 6+ years of intensive field use. Overvoltage incidents, physical trauma, or exposure to aggressive chemicals can reduce service life. Regular calibration and maintenance maximize longevity.

Q5: What certifications ensure test quality and safety?

Certified to ISO9001 (QMS), CE (EMC/safety), GB/T 4793.1-2007 (electrical safety), and fully compliant with IEC/ANSI test standards referenced globally.

Q6: What is the delivery cycle for customized orders?

Standard units ship in 5–7 business days; complex ODM projects (special firmware, IP ratings) require 3–5 weeks depending on requirements.

Q7: What warranty and support can I expect?

The PUSH PS-3045 is covered by a 24-month global warranty (parts/labor), lifetime email/phone support, and optional onsite calibration or training packages.
