Alarm indication on the display
It is necessary to enable alarm function from the PC and set for each quantity lower and upper
limit. If measured value is inside of set limits, alarm of proper quantity is not active. If value of
measured quantity gets outside of set limits, alarm of proper quantity is active and it is indicated on
the display. It is possible to select "memory alarm mode" when alarm is indicated permanently up to
reset from the PC.
Active alarm is indicated (if display is ON) by blinking of the value of
proper quantity on the display and arrow symbol appears at the LCD upper
side at the same time. Arrow 1 indicates active alarm for channel 1
temperature, arrow 2 for channel 2 temperature.
Notice:
if logger is operated at low temperature (below approximately
-5 °C), alarm indication by blinking can be indistinct. Indication by arrows
works correctly.
Messages displayed on the LCD beyond usual operation
If measured value is out of the measurable or displayable range numeric
reading is replaced by hyphens.
If memory is totally full filled in non-cyclic logging mode, logger is
switched OFF and message MEMO FULL appears on the LCD. It appears
also if logger is operated with switched OFF display.
New initialization of logger can occur in switching ON the logger
(immediately after displaying of all LCD segments for checking) e.g. after
replacement of totally discharged battery for new one. State is indicated by
INIT reading. It can be displayed for about 12 s.
If battery voltage drop occurred since last internal clock setting below
critical limit or battery disconnection for longer period than approximately
30 s, after display switch ON (during date and time display) all four arrows
appears as warning to check or set it again from the computer. However all
logger functions work without limitation.
If reading BAT is displayed periodically on LCD upper line (for 1 s with 10
s interval), the end of estimated battery life is coming – however logger
functions are not limited. Replace battery as soon as possible!
If reading BAT is displayed permanently, battery voltage is low and logger
is not possible to switch ON. If logger was switched ON before it, data
logging is stopped and logger is switched OFF. Communication
with computer can temporarily work. Replace battery as soon as possible!
Start / stop by magnet
The function must be enabled from the PC before. If only switching OFF by magnet is enabled,
it is of course necessary to switch ON the logger from the computer.
Notice:
It is not possible to combine function switching OFF by magnet and MIN/MAX
memory clear by magnet! User software enables only one of them to select.
