• U2 Nominal Output:1V
• Working Frequency: 45 Hz ~ 65 Hz
• Typical Value of Ratio Measurement Uncertainty: 5 ppm
• LCD Touch Screen
• The voltage output can be turned off or on with one key.
3. Application
• Power Frequency Current Precision Measurement
• Power Frequency Current Standard Source Traceability
☆ Power Frequency Current Precision Measurement |
|
• Combined with a precision voltmeter (such as TH0190) to build a precision current measurement system. • Measure power frequency current or calibrate power frequency current standard source. |
☆ Power Frequency Current Standard Source Traceability |
|
• The secondary voltage output by TH0680 is compared with the AC voltage reference through the zero voltage meter. • Ultra-high calibration uncertainty can be obtained, and precise traceability of power frequency current standard sources can be realized. |
