The Read button then reads the value of either the temperature
sensor or V2 voltage, depending on the Temperature Sensor
Select switch, and displays it in V2/Temperature Reading. The
Read button also displays the Temperature Offset stored in the
ADE7903; this value cannot be changed.
In the MCU Calculations area, the recommended equation
with Temperature Gain Correction and Temperature Offset
Correction from the data sheet is displayed and used by the
software to acquire a temperature reading in degrees Celsius in
the Temperature [deg C] box. The gain and offset correction
values can be modified if a different equation is desired.
