VOLTAGE SENSOR CALCULATOR

Important for accurate voltage measureing:
#define USE_INTERNAL_REFERENCE
Uncomment this line if you want to use the internal 1.1v reference voltage.
Be careful not to exeed the voltage on the analog PIN higher then 1.1v!!
#define USE_EXTERNAL_REFERENCE
Uncomment this line if you want to use and external reference voltage
Remind not to Exeed the voltage on the analog PIN higher then the external reference voltage!
#define REFERENCE_VOLTAGE
Measure the external reference voltage with an multimeter and enter it here in millivolts
Calculation is based on default SCALE_VOLTAGE 1.0
Measured voltage with multimeter: V
Voltage readout on transmitter: V
If you already have a scale voltage to calculate with.

New SCALE_VOLTAGE: V



CURRENT SENSOR CALCULATOR

Measured current load: A
Measured voltage on load: mV
MVOLT_AT_ZERO_AMP: mV

New MVOLT_PER_AMP: mV
