Voltage is measured as RMS which is much more precise than AC average. RMS metering is the only method that can accurately measure all AC power sources. The RMS voltage and frequency readings are ideal for monitoring modified sine waves such as solid-state generators, inverters and Uninterruptible Power Supply (UPS) products.
The Digital Monitor display will alternate between line voltage in RMS volts and line frequency in Hertz. The LCD display shows an "F" in front of the reading to denote frequency. Pressing the MODE button on the front of the Digital Monitor will cycle through the display modes. Both voltage and frequency are constantly monitored regardless of the display mode.
