2 Taking measurements
2.1 Voltage
2.1.1 General
When using the ADC-20/ADC-24 Terminal Board with the ADC-20 or ADC-24 to
measure voltages, you can connect the voltage source in one of two ways: directly,
by plugging straight into the channel, or indirectly, via a voltage divider.
2.1.2 Direct connection
For voltage sources measuring from -2.5 V to +2.5 V, use a direct connection to any
channel.
