4.10 Adjusting zero point The zero point of a Bronkhorst® flow meter/controller (the measurement signal that indicates the absence of a flow) is factory adjusted at approximately 20 °C and atmospheric pressure (ambient conditions), with the instrument positioned upright. Under normal circumstances (i.e. at stable process conditions), the zero point will remain stable. However, over time several factors can induce a slight deviation of the measured value from the zero point, causing the instrument to detect a flow when in reality there is none. -
Page 29: 4.10.1 Digital Procedure
4.10.1 Digital procedure Bronkhorst FlowSuite and FlowPlot provide an easy way to adjust the zero point of an instrument using RS-232 communication; the Autozero function automatically performs the procedure described here. To adjust the zero point using digital communication, set parameter values in the following sequence (see section... -

Modbus address blocks are two bytes long. Larger data types use up to 8 subsequent address blocks, resulting in a maximum variable length of 16 bytes. Values longer than the maximum length are truncated. For more detailed information about setting up a Modbus network with Bronkhorst® instruments, consult the Modbus manual (see Documentation). -
