SA4106A  
0.004% of FMAX, where FMAX is the output frequency in FAST  
mode when the input currents are IVPMAX = 16μARMS and  
IIPMAX = 16μARMS. The anti-creep function can also be  
disabled. The operation of the anti-creep function is fully  
described in the Input Signals and Output Signals sections.  
to be. The SA4106A can be calibrated to specification with a  
minimum of two pulses on the LED output whilst in  
STANDARD mode and utilizing an appropriate reference  
meter. This reading is independent of time and will be  
repeatable so as to consistently achieve the required  
accuracy for the full input current range that needs to be  
measured to IEC62053 accuracy. In Figure 6 the reference  
meter pulses are counted between two pulses of the meter  
under test. The meter under test is then adjusted so as to  
reflect the expected number of counted reference meter  
pulses. A worst-case scenario is for measurements obtained  
for only two pulses of the meter under test and N pulses from  
the reference meter. In this case the measurement resolution  
will be:  
Reverse Energy Flow Indication  
The SA4106A assesses the phase difference between the  
voltage channel signal and the current channel signal. If this  
phase difference is greater than 90 degrees then the DIRO  
signal will become active. This facility is designed to detect  
the wrongful connection of the meter. This operation is fully  
described in the Output Signals section.  
Starting Current

The SA4106A generates pulses on the LED and MON/MOP  
outputs for an input power greater than 0.01% or 0.004% of  
FMAX depending on the selected anti-creep threshold. This is  
to comply with the IEC requirement where the meter is  
required to generate pulses for currents greater than 0.4%Ib.

The corresponding calibration and repeatability results can  
never be more accurate than this measurement resolution.  
Power-On Reset  
Calibration and Repeatability  
The SA4106A has a power-on reset circuitry that activates  
whenever the voltage between VDD and VSS is less than  
3.6V ± 8%.  
The SA4106A provides an output (LED) that is used for  
calibration of the meter. The meter is calibrated by comparing  
the energy reading of the meter under test with the energy  
reading of the reference meter. The reference meter should  
have a considerably higher pulse rate than the meter under  
test. The accuracy to which the meter has to be calibrated will  
dictate how much higher the reference meter pulse rate has  
Power Consumption  
The power consumption of the SA4106A integrated circuit is  
less than 30mW.
