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 hours 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.
Consequently reading of estimated remaining battery capacity for
approximately 2 s is displayed (values 0 to 100%). It is valid if logger is
operated at temperature from -5 to +35°C. If logger is operated often outside
of the above temperature range battery life can be reduced to 75%, i.e. if
displayed remaining battery capacity drops below 25%, it is recommended
to replace the battery.
If display is switched ON
, actual reading of measured values is displayed -
channel 1 temperature (°C 1) at the LCD upper line, channel 2 temperature
(°C 2) at the LCD lower line. Symbol LOG indicates data logging in
progress – if it blinks, data memory is filled up to more than 90%.
Other measured or calculated values are displayed always after 5 seconds.
Instrument now displays channel 1 temperature (°C 1) and temperature
difference between channels (lower line "DIF"). T
DIF
= T1 – T2
Instrument now displays actual binary state of channel 3 (LCD upper line)
and channel 4 (LCD lower line). Symbol On indicates closed contact,
symbol OFF indicates open (or not connected) contact.
