Note
Voltages greater than 150V can only be applied to channels 0, 1, and 11. The rear Input Module must be
installed when measuring ac volts on channel 0.
Note
For 2-terminal measurements, the resistance accuracy given in this table applies to Channel 0 and makes
allowance for up to 0.05 ohm of lead wire resistance. You must add any additional lead wire resistance
present in your set up to the resistance values given in this table.
