The TRC AECM 20020 voltage/frequency monitor easy to use instrument is made with advanced microelectronics and provides accurate testing and monitoring of electrical outlets and systems. Constantly monitors voltage and frequency indicating potential improper polarity and ground wiring. Its small size and rugged construction allows for convenient installation in an electrical outlet or use as a portable service tool.
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.
Three display modes are available: Alternating Voltage & Frequency( VOLT/FREQ.): Voltage only (VOLTAGE): Frequency only (FREQUENCY)
Voltage Range 85 to 150 Vac RMS, Frequency Range 40 / 80 Hz, Operating Current 0.02 Amp, Under Voltage Alarm <102 Vac RMS, Over Voltage Alarm >135 Vac RMS, Under Frequency Alarm <55 Hz, Over Frequency Alarm >65 Hz, Outlet Type 120V/15A single phase, Operating temperature +32 deg F to +125 deg F. Approval is cUL/cUS. TRC part number is AECM20020.
