Low thermal potential terminal
No oil or air baths required
18°C ~ 28°C operating range
Small and rugged 

3. Applications
Calibrate high precision resistance meter
Calibrate standard resistance/precision resistance
Establish high precision current measurement system
 

☆ Calibrate Resistance Meter

Calibrate two-wire (≥ 10 mΩ) or four-wire (≤ 1 mΩ) resistance meters as standard resistors.
It can be used directly without placing in constant temperature oil tank or air tank.

 

☆Calibrate Standard/Precision Resistance

Calibrate precision resistance with precision resistance bridge (such as TH0210).

☆ Establish High Precision DC Measurement System

Establish the current measurement system with I/I transfer standard and precision voltmeter.
