Environment
The meter should be tested at the same temperature as the testing equipment. The ideal temperature is about 23 ºC (73 ºF). Make sure the meter is warmed up sufficiently before testing.
A warm-up time of 30 minutes is recommended before beginning accuracy verification testing. At the factory, the meters are warmed up to their typical operating 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 self-heating.
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 www.se.com.
Reference device
To help ensure the accuracy of the test, it is recommended that you use a reference device with a specified accuracy that is 6 to 10 times more accurate than the meter under test. Before you start testing, the reference device should be warmed up as recommended by its manufacturer.
