Product Description

TH0300 High Power Resistor Standard


1. Summary
TH0300 is a series of reference high power resistance standards, it's applied for precise AC and DC current measurement at high power conditions.

2. Features
Nominal resistance: 0.1 Ω ~ 10 Ω 
Maximum operating current: 11 A
Long-term stability: 5 ppm/year (typical)
Temperature coefficient: 1 ppm /°C
Low thermal potential
On-site test

3. Applications

Establish high precision current measurement system
Calibrate the DC current standard source
Calibrate high precision resistance meter
 

☆ DC High Current Precision Measurement

When I ≥ 11 A, establish the current measurement system with I/I transfer standard and precision voltmeter.

 

☆ DC Small Current Precision Measurement

When ≤ 11 A, TH0300 can be directly used as I/V transfer standard.
