Mp = Number of revolutions per pulse.
Examples:
For a mechanical meter:
Ke = (Kh) (Mp) = Kh = 7.2 Wh * Mp = 2 Revs = Ke = 14.4 Wh
1 Rev
where:
Mp = 2/1 = 2 revolutions per 1 pulse
Kh = 7.2 watthours per 1 revolution
For a solid state meter:
Ke = (Kh) (Mp) = Kh = 1.8 Wh * Mp = 1 Rev = Ke = 1.8 Wh
where:
Mp = 1/12 = 1 revolution per 12 pulses
Kh = 1.8 = watthours per 1 revolution
• The formula that the RM-111 uses to calculate percent registration is as follows:
