Data Logger

This is a data logger for the voltmeters included in the device - A1, A2, A3, SEN, IN1

Connect your input signal between any of the above inputs, and any GND pin. For sensors requiring a biasing voltage, use the SEN input which is pulled-up to 3.3V via an internal 5K resistor. For example, to measure the voltage induced in a solenoid due to a changing magnetic field, connect one end to A1, and the other end to GND.

If induced signals are very small, use the A3 input, and also connect a 100 ohm resistor from Rg to GND. This amplifies your signal by around 100 times.
