3.3.5.4. Apply Conversion (parameter)
There are two different methods of converting primary current
(measured from the CT) to secondary current.
3.3.5.4.1.
Use Points 1&2
The two-point method of current calibration is performed by
measuring the values of primary and secondary current at
two different heat levels. This procedure can be found in
Section 7
of the
EN7000 Technical Manual
3.3.5.4.2.
Use Turns Ratio
This method calculates the secondary current by multiplying
the primary current by the transformer turns ratio.
3.3.5.4.3.
Off
No conversion will be done. Select this option if using a
secondary toroid to measure the current. In this case the
Sensor
must be set to
Toroid
in the
Configuration
menu.
3.3.5.5. Point 1 (Pri) (parameter)
Lower primary current reading.
3.3.5.6. Point 2 (Pri) (parameter)
Higher primary current reading.
3.3.5.7. Point 1 (Sec) (parameter)
Lower secondary current reading.
3.3.5.8. Point 2 (sec) (parameter)
Higher secondary current reading.
3.3.5.9. Turns Ratio (parameter)
Transformer turns ratio (usually found on the
transformer nameplate).
