VoltgeADC |
| Reads the Voltage of the ADC pin for diagnostic purposes. With no current flowing through the sensor, the voltage reading should be 2.50V. If that is out, then enter precise VDD within properties | |

|
VDD |
| For improved accuracy, measure the voltage across the supply of the current sensor, then enter that as VDD voltage. | |
|
|
Offset current adjust (Amps) |
| Offset current adjusts the curent output when comparing to a current monitor. For example current from the componet shows 2.0 Amps and curent monitor shows 1.5 Amps. For the current offset enter -0.5 | |
|
Channel |
| Analogue Input Channel - Which pin is the analogue input connected to? | |
|
|
VRef option |
| Defines what is used as the ADC maximum reference. ADC Range = GND to VRef Voltage VDD - Defines the microcontrollers power supply pin as the max reference, VREF+ Pin - Dedicated pin on the microcontroller to allow for a variable reference voltage. | |
|
|
Conversion speed |
| Clock setting to select how fast the ADC peripheral will perform an ADC conversion. The FRC setting is based on a RC time base and so will vary with temperature and pressure. Other settings are generally based on divisions of the master clock. | |
|
Acquisition cycles |
| Number of micro seconds to wait for the ADC input to charge before starting the analogue sample. | |
|
Average Loop (1 - 255) |
| The more higher the value, the more stable and accurate result would be. Results will take longer. Try 200 | |
|
|
Offset Voltage |
| The voltage value when no cureent is flowing This is normally 2.5V for bidirectional and 0V for Unidirectional | |
