1. Responds to Function 5 (direct operate), Qualifier Code 7 or 8, Control Code 3, Count 0,
On 1 ms, Off 0 ms ONLY.
2. Responds to Function 6 (direct operate - no acknowledge), Qualifier Code 7, Control
Code 3, Count 0, On 1 ms, Off 0 ms ONLY.
(n–d)
3. The multiplier = 10
6 per energy format scale and d = number of decimal places.
4. Example: If energy format = 7.2 K and watt-hours counter = 1234567, with n=3 (k-
scale) and d = 2 (2 digits after decimal point), then multiplier = 10
energy is 1234567 × 10 Wh, or 12345.67 kWh.
5. Values greater than 150 V secondary read 32767.
6. Values greater than 300 V secondary read 32767.
7. Values greater than 10 A secondary read 32767. For the 1 A model, the multiplier is (2/
32768) and values above 2 A secondary read 32767.
8. CT ratio = (numerator × multiplier) / denominator.
9. PT ratio = (numerator × multiplier) / denominator.
10. Clear via Function 2 (write), Qualifier Code 0.
, where n and d are derived from the energy format. n = 0, 3, or
