TUNKIA TH0310 Resistance Standard

1. Summary

The TH0310 is a series of working precision standard resistors featuring excellent long-term stability and low temperature coefficient. These resistors can be used together with precision I/I conversion standards and precision voltmeters to achieve wide-range precision current conversion measurements.

2. Features

• Long-term stability: 5 ppm/year (typical)

• Temperature coefficient: 1 ppm/°C

• Wide resistance range available from 1 mΩ ~ 100 MΩ

• Low thermal potential terminal

• No oil or air baths required

• 18°C ~ 28°C operating range

• Small and rugged

• Can be customized according to customer needs.

3. Applications

• Calibrate high precision resistance meter.

• Calibrate standard resistance/precision resistance.

• Establish high precision current measurement system.

☆ Calibrate Resistance Meter

TH0310 Resistance StandardCalibrate 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

TH0310 Resistance Standard Calibrate Standard/Precision Resistance

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

☆ Establish High Precision DC Measurement System

TH0310 Resistance Standard Establish High Precision DC Measurement System

• The TH0310 can be used together with DC I/I conversion standards (ratio standards) and precision voltmeters to form a DC high-current measurement system.

• Note: When measuring current, the applied current should not exceed the maximum operating current of the standard resistor. For precision current measurements, factors such as the rated power and power coefficient of the resistor should also be taken into consideration.
