Schneider Electric HRB1684301-01 user manual Reference device or energy standard, Energy pulsing

Chapter 15—Verifying accuracy PowerLogic™ PM5500 series user manual

A warm-up time of 30 minutes is recommended before beginning energy 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.schneider-electric.com.

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.

Location of energy pulsing LED

PM5560 / PM5561 PM5563 A Alarm / energy pulsing LED

NOTE: The alarm / energy pulsing LED on the PM5561 is permanently set for energy pulsing and cannot be disabled or used for alarms.

•The meter is equipped with digital outputs. When you configure a digital output for energy pulsing, the meter sends voltage pulses to the digital output port, which are then used to determine the accuracy of the meter’s energy measurements.
