Description
DADA Analogue Insulation Resistance Tester Y-5074A
An insulation tester applies a DC test voltage and measures the leakage through the insulation. It is the instrument that says whether a cable or winding is safe to energise.
Available Sizes
- 2–2000 MΩ, 1000 V (Y-5074A)
- 1–1000 MΩ, 500 V (Y-5074B)
- 0.1–100 MΩ, 500 V (Y-5074C)
Key Features
- Test voltage must match the circuit rating — 500 V for most installation work
- Disconnect and prove dead before testing; the instrument outputs hundreds of volts
- A falling reading over time matters more than one absolute number
