• Maximum number of recordable readings: 32765.
• A runtime is displayed during the recording.
• The data of all connected pressure transducers are recorded, i.e., in
case of two connected pressure transducers a maximum of 16382
readings per pressure transducer will be recorded.
• Recording starts, if ”Log data” is set to a value from 1 to 3600 seconds
(see “Configuration”, pg. 35) and stops 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 a power failure the recording interval is set to ”Off”, the stored
readings can be read out.
• ”Graphic” (with or without function ”log data”) displays maximum 240
readings of the selected pressure transducer.
• If ”Graphic” with function ”log data” is selected, it is possible to extend
the time scale to the next interval by turning the selection knob when
the end of the displayed time scale is reached.
• If changing the displayed pressure transducer (without function ”log
data”) the graphic starts anew.
• Readout of the stored readings is possible via RS 232 interface with the
selected transfer parameters (see “Interface parameters”, pg. 43).
• The data output format is ASCII.
• First the time is recorded, then the readings of all pressure transduc-
ers separated by space characters followed by the pressure unit.
Examples:
1. Data output in case of one connected pressure transducer, recording
interval 1 second:
000.00:00:00 0105.8 Torr
000.00:00:01 0105.8 Torr
000.00:00:02 0105.8 Torr
000.00:00:03 0105.8 Torr
000.00:00:04 0105.8 Torr
000.00:00:05 0105.8 Torr
