sets optimum bias and reference
conditions on chip. Calibration of the SA2007M should be
done on the voltage input as described in Typical Application.
Motor pulse rate select (MP1 and MP0)
The pulse rate of the motor driver output of the SA2007M is
selected by the inputs MP1 and MP0. Three pulses rate
options are available as shown in the following table:

Please note that the device will not perform metering functions
as described in this document while in test mode.
Rated condition select (RATED)
The rated condition select pin gives the option of having a 3:2:1
scaling ratio for the rated meter current. This feature is
particularly useful in circumstances where a manufacturer
requires a meter for use in a system rated for two different
conditions, for example 230V/60A and 230V40A. With the
rated condition select the SA2007M allow for the development
of different rated meters requiring minimal changes. The
following table below lists the option available (assuming the
rated condition to be 230V/60A).

OUTPUT SIGNALS
Motor output (MOP, MON)
The MON pulse will follow the MOP pulse within 142ms. This
prevents that the motor armature is in the wrong position after a
power failure. Both MOP and MON outputs are active high.

LED output (LED)
The LED output pulse at a fixed rate of 6400 pulses per kWh.
The LED output is active low. The LED waveform is shown
below:
An integrated anti-creep function prevents any output pulses if
the measured power is less than 0.02% of the meters rated
current.
Selected input indicator (SEL1)
The SA2007M continuously compares the power
consumptions on current channel 1 inputs and current channel
2 inputs. The larger of the two measurements are used for
metering. The SEL1 output pin indicates which channel is
currently being used for the pulse output.
