HIGH RESISTANCE STANDARDS VRS-100 IET LABS
The High Resistance Standards VRS-100 from IET Labs offer precision and reliability for testing meggers and other instruments requiring high resistance values.
Here are the key features and specifications:
- Resistance Values: Available in sets of nine, ten, or eleven resistors spanning a wide range from 1 kΩ to 10 TΩ. The set includes values such as 1 kΩ, 10 kΩ, 100 kΩ, 1 MΩ, 10 MΩ, 100 MΩ, 1 GΩ, 10 GΩ, 100 GΩ, 1 TΩ, and 10 TΩ (depending on the model).
- Accuracy: Offers high accuracy, with tolerances as low as 20 ppm, ensuring precise measurements for calibration purposes.
- Voltage Range: Standard voltages of up to 5 kVDC are provided, with optional 10 kVDC voltages available for higher resistance values.
- Temperature Coefficient and Stability: Boasts excellent temperature coefficient (as low as 5 ppm/°C) and stability (as low as 10 ppm/year), ensuring consistent performance over time.
- Calibration Method: Resistance values of 10 MΩ and below are calibrated with a Fluke 8508A Reference DMM while values above 10 MΩ are calibrated with a Keithley 6517B at 1000 VDC.
- Customization: The VRS-100 Series can be custom-made to accommodate any set of resistance values ranging from 0.01 Ω to 10 TΩ in a single housing.
- User Versions: Two user versions are available – binding posts or rotary switch – providing flexibility in operation and connectivity options
Overall the High Resistance Standards VRS-100 Series offers a comprehensive solution for high-precision resistance measurements making it ideal for calibration of Hipot Testers, Megohmmeters, and other instruments.
