About this document
D-R 300-40 Dust Meter Manual by michael is a document available to read on EtoBox.
The document discusses modifications made to the software of a Dust Concentration Meter D-R 300-40 according to EPA requirements. The software change allows the meter to provide relay output signals indicating normal/abnormal and measuring/control modes. It also allows a digital input signal for manual start of control cycles. When the limit value is set to 3 mA and an input is closed, the control cycle will activate on startup and when the input is opened, repeating every 4 hours if the input remains open.
