1. Supports calibration of megohmmeters with rated voltage ≤10kV, applicable to production, repair and verification scenarios.
2. Standard resistor and digital meter can be used independently, with 100Ω minimum resistance step and 10kV maximum withstand voltage.
3. Compact structure, stable performance and user-friendly operation, suitable for industrial and enterprise calibration needs.
4. Digital meter measures up to 10000V DC voltage with high accuracy and fast 25-second response time.

1.Standard Number Table

Measurement range: Voltage range: 0-10000V

Basic error:

DC voltage U	≤1000V：  ±(0.4% reading+0.1% full degree) >1000V：  ±(0.5% reading+0.5% full degree)
Peak Voltage (Uf)	≤1000V：  ±(1% reading+0.5% full degree) >1000V：  ±(0.5% reading+0.5% full degree)

The response time of the digital meter is about 25 seconds.
