Manual-no.: 999162 // 19/01/2011Notes concerning the function data logger (recording and sending of data)• Maximum number of recordable readings is 32765.• During recording the runtime is displayed.• The data of all connected pressure transducers are recorded, i.e. for two pressure transducers maxi-mum 16382 readings per pressure transducer are recorded.• Recording starts, if ”Log data” is set to 1 ..... 3600 seconds (see menu ”Configuration - Log data”) andstops if ”Log data” is set to ”Off” or the device is switched off.• If the recording interval is changed, stored readings are deleted and recording starts again.• After power failure the recording interval is set to ”Off”, the stored readings can be read out furtheron.• ”Graphic” (with or without function ”log data”) displays maximum 240 readings of the selected pres-sure transducer.• If ”Graphic” with function ”log data” is selected it is possible to extend the time scale to the next inter-val if the displayed time scale is reached by turning the selection knob.• If changing the displayed pressure transducer (without function ”log data”) the graphic starts anew.• Read out of the stored readings is possible via RS 232 interface with the selected transfer para-meters (see ”Configuration of the interface”).• The data output format is ASCII.• First the time is recorded, then the readings of all pressure transducers, separated by space charac-ters, after the last reading the pressure unit is recorded.Examples:1. Data output of one pressure transducer, recording interval 1 second:000.00:00:00 1005.8 mbar000.00:00:01 1005.8 mbar000.00:00:02 1005.8 mbar000.00:00:03 1005.8 mbar000.00:00:04 1005.8 mbar000.00:00:05 1005.8 mbar000.00:00:06 1005.8 mbarEnd2.

The outputof 32765 readings from one sensor takes up to 8 minutes at 19200 baud, longer than 1 hour at 2400baud.Recording of data is possible with any terminal program.Example: Windows* HyperTerminal: Select ”Transfer menu - Capture text”. In the file box, type a de-scriptive name for the file, and then click ”Start”. Send command ”IN_PV_D” or select at the DCP 3000”RS 232 - Data - Send”.* Windows is a trade mark of Microsoft Corporation in the USA and other countries.
