Uses of Volt-Amp Measurement
Because it represents the amount of energy computing systems may draw from a power grid, the VA
is 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
Safety Precautions
Make sure you have a clear and safe area when powering any equipment, remove any drills bits etc
before testing any equipment. Always read equipment compliance plates.
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.
