Amperes (aka Amps)
An amp is the unit used to measure electrical current as it flows past a specified point.
Watts
A watt is the unit used to measure the amount of actual flowing electrical energy.
Volt-Amps
A volt-amp is the unit used to measure the apparent electrical power used by computing equipment. Mathematically, it is
expressed as volts times amps (V*A). Because it represents the amount of energy computing systems may draw from a power
grid, Volt-Amp measurements are used to determine the kind of wiring and circuit breakers required to support the computing
equipment in question.
Watts and VA - Detailed Explanation
The power drawn by equipment is expressed in Watts or Volt-Amps (VA). The power in Watts is the real power drawn by the
equipment. Volt-Amps are called the “apparent power” and are the product of the voltage applied to the equipment times the
current drawn by the equipment. Both Watt and VA ratings have a use and purpose. The Watt rating determines the actual power
purchased from the utility company and the heat loading generated by the equipment
Disclaimer
Meter Mode is to be used for quick simple indicative electrical parameter measurements. Providing reasonably
accurate readings without the need to carry any other instruments. It is not intended to replace specific, more
accurate individual test equipment, nor is its purpose to replace prescribed testing requirements. It in doubt
please consult a qualified electrician when unsure or perform proper test procedures.
