Voltage input

Voltage in the range 0 to 5V can be measured using the screw terminals on DrDAQ. Resolution is 5mV and accuracy is 3%.

Unlike many dataloggers, DrDAQ take readings very quickly (up to 15,000 per second). This means that the DrDAQ datalogger is equally suitable for measuring events of a short duration (such as the 'bounce' of a mechanical switch) or for long term data logging (the discharge of a battery over several days).

The waveform below shows the voltage in a simple RC charge/discharge circuit.
