The Data Logger
The meter provides a data logger.
Prior to use
, it must be configured and then
activated. You can choose from the following logger types:
• DIFF (signal-controlled logging of measured variable and temperature)
• INT (time-controlled logging at a fixed interval)
• DIFF+INT (combined time- and signal-controlled logging)
• SHOT (manual logging by pressing the
STO key)
The data logger records up to 5000 entries and saves them in a circular buffer.
Already existing entries will be overwritten.
The following data are recorded: primary value, temperature, time stamp and device
status.
Option 001 SOP can be used to set up an access lock for the data logger, which in the
absence of an access code allows only logger data to be displayed (see page 35).
The Paraly SW 112 PC software allows convenient management of the data logger.
It is always the currently selected process variable which is recorded. The “STO” icon
and the memory address is displayed briefly to indicate that an entry is being saved.
