| ☆ 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. |
