==== | ==== Affected devices ==== | ||
WBIO-AI-DV-12/4-20MA | WBIO-AI-DV-12/4-20MA shipped before May 20, 2019. | ||
==== | ====Description==== | ||
Current measurement error in WBIO-AI-DV-12/4-20MA can be up to 1%. | |||
==== | ====Reasons and detailed description==== | ||
The nominal value of the input protective resistor is selected too large relative to the internal resistance of the ADC. | |||
==== | ====Workarounds==== | ||
no | |||
==== | ====Scheduled fix=== | ||
Starting from May 20,2019 components, providing the error is not more than 0.1%+0.003 mA, are installed in WBIO-AI-DV-12/4-20MA | |||
