The valve control module VAEM makes precise switching of solenoid valves easier than ever. Up to 8 channels can be parameterised individually. A temporary resolution of only 0.2 ms and the control of the valves via current – not voltage – enable extremely high preci­sion, e.g. for dispensing applications. The holding current reduction saves energy and minimises heat input.

This Application Note explains about VAEM-V Control, Read/Write Parameters & Save Parameters.

This Application Note describe the most common terms about the evaluation of results of a dispensing or pipetting application. In particular: accuracy, trueness, precision, repeatability, reproducibility, coefficient of Variances (CV), mean and standard deviation as well as maximum permissible error.

This application node includes examples how to establish a Modbus/TCP communication with the CTEU-EP node.
