TERMINOLOGY  
Anti-Creep Threshold  
Limit Range of Operation*  
The anti-creep threshold is defined as the minimum energy  
threshold below which no energy is registered and therefore  
no pulses are generated on the LED or motor drive outputs.  
Extreme conditions which an operating meter can withstand  
without damage and without degradation of its metrological  
characteristics when it is subsequently operated under its  
rated operating conditions.  
Positive Energy  
Positive energy is defined when the phase difference  
between the input signals IIP and IVP is less than 90 degrees  
(-90..90 degrees).  
Maximum Rated Mains Current (IMAX  
)
Maximum rated mains current is the specified maximum  
current flowing through the energy meter at rated operating  
conditions.  
Negative Energy  
Negative energy is defined when the phase difference  
between the input signals IIP and IVP is greater than 90  
degrees (90..270 degrees).  
Constant*  
Value expressing the relation between the active energy  
registered by the meter and the corresponding value of the  
test output. If this value is a number of pulses, the constant  
should be either pulses per kilowatt-hour (imp/kWh) or watt-  
hours per pulse (Wh/imp).  
Percentage Error*  
Percentage error is given by the following formula:

Nominal Mains Voltage (VNOM  
Nominal mains voltage (VNOM) is the voltage specified for the  
energy meter at rated operating conditions.

NOTE: Since the true value cannot be determined, it is  
approximated by a value with a stated uncertainty that can be  
traced to standards agreed upon between manufacturer and  
user or to national standards.  
Maximum Output Frequency (FMAX  
)
The maximum output frequency (FMAX) is the output  
frequency in FAST mode when 16µARMS input current with  
zero phase shift are applied to the voltage and current inputs.  
Both the voltage and current inputs saturate at an input  
current magnitude of 25µA, or at 17.68µARMS when using sine  
waves. The maximum input current on each channel is  
therefore defined to be 16µARMS, which leaves about 10%  
headroom to the saturation point. In FAST mode the nominal  
maximum output frequency of 5kHz is achieved under such  
conditions.  
Rated Operating Conditions*  
Set of specified measuring ranges for performance  
characteristics and specified operating ranges for influence  
quantities, within which the variations or operating errors of a  
meter are specified and determined.  
Specified Measuring Range*  
Set of values of a measured quantity for which the error of a  
meter is intended to lie within specified limits.  
Repeatability of Error Test**  
This test shall be carried out at 0.05Ib and Ib at UPF load  
under reference test conditions. Twenty error samples shall  
be taken at time intervals of 30 minutes. Identical test  
conditions shall be maintained throughout the test. For an  
acceptance test six error tests may be carried out at time  
intervals of at least 5 minutes.  
Specified Operating Range*  
A range of values of a single influence quantity, which forms  
a part of the rated operating conditions.
