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
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. |
