Phenix Technologies’ AC/DC Kilovoltmeters voltage measurement functions include AC Average, AC RMS, AC Peak, AC Peak/√2, DC Average, DC Peak, DC Ripple. Traceable to NIST standards, units can be used for calibration and general high voltage measurements. Voltage divider can also be used with other measuring devices such as an oscilloscope or multimeter. These units are precise, reliable, and satisfy a wide range of testing applications.

Voltage Measurement Functions/Frequency Range

• AC AVERAGE: Average Value of the Rectified AC Voltage (Equivalent to RMS Value divided by 1.11 for a Pure Sinusoid)
• AC RMS: True RMS Value of the AC Voltage
• AC PEAK: Average of the Positive and Negative Peak Voltage Values
• AC PEAK /√ 2: Average of the Positive and Negative Peak Voltage Values, divided by √ 2 (Equivalent to RMS Value for a Pure Sinusoid)
• DC AVERAGE: Average Value of the DC Voltage
• DC PEAK: Peak Value of the DC Voltage
• DC RIPPLE: Average of the Positive and Negative Peak Values of the Filtered Ripple Voltage

Uncertainty (Based on k=2, Confidence Interval of 95%)

• Metering Head: 0.5% of reading from 10-100% of range
• Divider Ratio: 0.4%
• Overall: 0.75% of reading from 10-100% of range
