42
You can configure the comparator function using
the 9674 RS-232C PACKAGE.
The comparator function tests whether the temper-
ature is within a predetermined temperature range,
and displays a test result on the LCD. If the tem-
perature is outside the range, the buzzer sounds.
The following conditions apply to comparator value
settings (upper and lower temperature limits) and
test results: In manual recording mode, the com-
parator function checks the temperature at the
time of recording. During interval recording, the
comparator function checks the temperature cur-
rently on the display.
You can set comparator values for individual Items
(product names).
