6.4: Performing Watt Hour Accuracy Testing (Verification)
To be certified for revenue metering, power providers and utility companies must
verify that the billing energy meter performs to the stated accuracy. To confirm the
meter’s performance and calibration, power providers use field test standards to
ensure that the unit’s energy measurements are correct. Since the Shark® 200 meter
is a traceable revenue meter, it contains a utility grade test pulse that can be used to
gate an accuracy standard. This is an essential feature required of all billing grade
meters.
• Refer to Figure 6.5 for an example of how this process works.
• Refer to Table 6.1 for the Wh/Pulse constants for accuracy testing.
