After connecting the logger to the computer reading of logger info is enabled by means of the
PC software and also setting of the instrument accordingly to the user needs (menu
Configuration /
Setting of instrument parameters
). Before logging start it is necessary:
•
check or optionally set the logger real time clock
•
select suitable logging interval
•
select logging mode (cyclic or non cyclic)
•
set for each channel type of temperature probe (Pt1000 or Ni1000)
•
disable channels for logging with not connected temperature probe
•
switch ON the logger (or switch OFF, if it is about to be switched ON by magnet or
automatically with delayed start)
•
enable or disable the option to switch ON the logger by magnet
•
enable or disable the option to switch OFF the logger by magnet
•
enable or disable the option to clear minimum and maximum value memory by magnet
•
set date and time of logger automatic switching ON logger or disable this option
•
select if record runs permanently or only if alarm is active
•
If alarms are about to be applied, set both limits for each measured quantity and enable
alarm
•
optionally enable permanent alarm indication (alarm with memory)
•
switch ON or switch OFF the display of logger
•
optionally switch ON displaying of MIN/MAX values on the LCD
•
reset memory of MIN/MAX values (if needed)
•
check free space in data memory, optionally erase data memory of the logger
•
enter password if protection against unauthorized manipulation with the logger is necessary
Logging interval between to subsequent measurements is specified by the user. Memorizing of the
first value is synchronized with the internal real time clock, so the logging is performed at sharp
multiples of minutes, hours and days. E.g. after starting the logging with the 15 minute interval the
first value is not stored immediately, but after the internal clock gets the status of a quarter, a half or
a whole hour. After starting the logging with the 6 hour interval the first value is stored at that
whole hour to perform the storing also at 00.00, i.e. at the beginning of the day. First storing is
performed at 6.00,12.00, 18.00 or 00.00hour - at the hour from the above nearest to the logging
start. After communication with computer or after start by magnet logger automatically waits for
the nearest whole multiple of time and then first measurement is performed. This is also necessary
to take into account when setting time of automatic logger switch ON.
Notice:
If logger operates as permanently connected to the computer, using of magnet
start/stop is disabled.
To enable the logger control by magnet is suitable only in cases, when possibility of
unauthorized manipulation to the logger operation is eliminated.
Reading on the display in usual operation (logger switched ON)
After switching ON the logger all LCD symbols are displayed for checking
the display.
Then actual date and time in logger is displayed for approximately 4 s.
