2
Accuracy specification is ±(% of programmed value + fixed offset) in those cases where a percentage + fixed term are given. Otherwise,
the specification is given as a negative and positive percentage error term. This specification may degrade when the unit is subject to an
RF field of 3V/meter, the unit is subject to line spikes of 500V, or an 8kV electrostatic discharge.
3
For resistance ranges 3 through 4, accuracy specifications apply with input voltages ≥6V.
4
DC current accuracy specifications apply 30 seconds after input current is applied.
5
Accuracy specification is ±(% of reading + fixed offset). Measurement is 1000 samples. This specification may degrade when the unit is
subject to line spikes of 500V, or an 8kV electrostatic discharge.
