Note 1: PATH resistance limits are 0.5Ω to 2Ω for 8-bit modules, 0.75Ω to 3Ω for 12-bit,
1Ω to 4Ω for 16-bit and 1.5Ω to 6Ω for 24-bit channels.
Note 2: All results in red are taken with the DMM offset to remove the PATH result form the answer
The test should be repeated for each channel of the module.
To aid users to establish test limits the following generic tables should be used for the standard modules. The tables
can be copied to record the results for each channel.
Similar principles can be applied to custom modules, if guidance is needed please consult your Pickering Interfaces
representative.
