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.
