4.6 Operating and function principle of the
date logger in 7280 measuring amplifier
The data logger can, if the 7280 measuring amplifier is not in the measuring mode, be read by
the menu option 2.7 LOGG - SENDING or by the command „A“ via the interface. Outside of the
measuring mode the data logger is deleted only by the menu option 2.7 LOGG - DELETION.
If the 7280 measuring amplifier is in the measuring mode, the data logger can be read with the
command „A“ and be deleted with the command „B“.
If the measuring mode is being switched on from the menu option 1 MEASURING-sensor
selection, the starting time of the measurement, the current sensor designation, the final value
of the measuring range, the adjusted measuring rate and the logger mode (e.g.: AUTO 1 ms)
are saved in the logger.
NOTE: All previous measured values are deleted here!
With the read-out of the data logger via the serial interface different adjustments of the 7280
are sent.
a.) letter head
b.) starting time of the measurement
c.) sensor designation
d.) display final value
e.) adjusted measuring rate
f.)
adjusted logger mode
g.) thereafter the measured values
In the HAND MODE the measured values are always logged with the time. With the data in the
AUTOMODE the measured value is logged. A time can be assigned to each measured value
by the indicated starting time.
Since in GRAPHS and in the WINDOW MODE trigger events smaller than 1 sec can occur, an
additional time log is not possible.
