temperature before calibration to help ensure that the meters will reach their optimal accuracy at operating temperature.
Most high precision electronic equipment requires a warm up time before it reaches its specified performance levels. Energy meter standards allow the manufacturers to specify meter accuracy derating due to ambient temperature changes and
Your meter complies with and meets the requirements of these energy metering standards.
For a list of accuracy standards that your meter complies to, contact your local
Schneider Electric representative or download the meter brochure from
Reference device or energy standard
To help ensure the accuracy of the test, it is recommended that you use a reference device or reference energy standard with a specified accuracy that is 6 to 10 times more accurate than the meter under test. Before you start testing, the reference device or energy standard should be warmed up as recommended by its manufacturer.
NOTE: Verify the accuracy and precision of all measurement equipment used in accuracy testing (for example, voltmeters, ammeters, power factor meters).
Energy pulsing
You can configure the meter’s alarm /energy LED or one of the digital outputs for energy pulsing.
•The meter is equipped with an alarm / energy pulsing LED. When configured for energy pulsing, the LED emits pulses that are then used to determine the accuracy of the meter’s energy measurements.
