Energy pulsing

Energy pulsing LEDs and digital outputs can be used for energy pulsing.

Your meter is equipped with two types of energy pulsing LEDs: visible light and infrared. These LEDs emit pulses that are then used to determine the accuracy of the meter’s energy measurements. The pulses of light indicate accumulated energy; the meter’s accumulations are compared with the reference/standard’s accumulated energy in order to help determine the meter’s accuracy.

The meter’s digital output can also be used for energy pulsing. A closing (low impedance) and then opening (high impedance) of the digital output represents a pulse. If the accuracy testing equipment has a voltage requirement, a current-limited wetting supply voltage must be provided.

NOTE: Digital outputs on option modules should not be used for meter accuracy testing.
