6.2.2: Kh Testing Procedure
As mentioned earlier, the MP200 unit is equipped with eight light pulse outputs, each
of which generates one pulse when a defined unit of energy is measured by the meter.
The defined unit of energy is given as Kh (Pulse Constant) times "1 kilowatt-hour."
The Pulse Constants are given in Table 6.1 and are printed on the MP200 unit’s serial
number label next to "Kh-TV<150V" and "Kh-TV>150V."
The diagram below shows a typical test setup:

Typical standards are: Radian Research RD20 & RD21 or a Watt-hour Engineering
Company Three Phase Automated Test System.
