Meter Calibration

7.1.1.

Calibration LED

The Focus kWh has an infrared light emitting diode (LED) that emits energy pulses. The calibration
LED is deactivated 24 hours after the meter powers up. Once reactivated (recycle power), the
calibration LED remains active for 24 hours.
The calibration LED is accessible from the front of the meter cover. The user can fix an LED pickup
device to the front of the meter.
The calibration LED is enabled to produce stable pulses in no more than two seconds following meter
power up.
The calibration LED produces pulses in response to energy whether it is delivered (positive) or received
(negative).
Registration verification testing requires no more than 30 seconds at full load.
The calibration LED is visible in meter shop lighting and room temperature conditions.
