Description


SOUTHWIRE 2453
Digitally monitor and meter all your AC power sources for your personal safety and appliance protection.
This compact, 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. 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.

  • Fully tests incoming power for: Open ground, Reverse polarity, High/Low voltage
  • Three display modes available: Alternating voltage and frequency (VOLT/FREQ.), Voltage only (VOLTAGE),Frequency only (FREQUENCY)
  • Accurate testing and monitoring of all AC power source types
  • RMS voltage and frequency meter
  • Multi-tone fault alarm
  • Hands-free auto reset
  • Advanced microelectronics
  • One-button operation
  • Wiring diagnostics
  • LCD display with LED backlight

    This little guy constantly monitors incoming power and alerts you to high or low voltage conditions as well as incorrect line frequency. It will also alarm if the wiring is miswired (reversed polarity) or no ground line is present. I leave one plugged in whenever we're camped and a quick glance at the display lets me know if how much line voltage we've got in the camper. More piece of mind.

    This voltmeter can tell you a lot. If it reads below 105 VAC then shut off your air conditioner. If the voltage climbs by more than 5 VAC when the compressor cycles off, there is a problem with your generator voltage regulator, or if you are plugged in, the receptical you are plugged into is worn out - the clips inside of it are not holding tightly to your RV cord. This will cause the cord to overheat, and low voltage is bad for your air conditioner compressor. If you are below 105 VAC even with the air conditioner off, you need to increase the voltage before re-starting the air conditioner. When running on the generator, check the Hertz. If it is not 60, + or - 1 HZ, then have the generator checked out. You can read my posts on RV.Net Golden HVAC

    The temperature was over 102 degrees. With the AC running, the breakers blew as soon as my wife turned the microwave on while she blow-dried her hair. I did not have time to stop her. With fear in her eyes at the rising temperature, I had to explain everything would be okay, but honey this is not like a motel. The breaker reset in the airstream was easy, but took me a while to remember that there were breakers on the pedestal outside. I was beginning to worry myself. Then I looked at what numbers were reading on this device. The neat thing about this product was that there were about 10 less volts at the Park, running at about 116, than there is when hooked up at home, which runs at 126. This told me I was getting less juice than when parked at home. The morning we were leaving as I was getting us ready to leave the alarm on the device went off, looking at the numbers, we were down 10 more volts short. I believe there were twice as many campers as the day before when the breakers blew parked at the campground. I am not an electrician. This device tells you if there is a problem. It works and there really is a need to know.
