7. MEASUREMENT
The measuring instruments ALMEMO
®
2290-4 provides the following options
for the acquisition of measuring data:
1. Continuous measurement of a selectable meas. point, see 7.1 and man. 6.4.
Output of measuring data to the analogue output, see 8. and man. 5.1.1.
2. Single measuring point scan, see 7.2 and manual 6.5.1.1.
3. Cyclic measuring point scan, see 7.3 and manual 6.5.1.2.
4. Continuous measuring point scan, see 7.3.1 and manual 6.5.1.3.
Total Clearing of All Measured Values
All max, min and average values of all channels are automatically cleared at the
START of each cyclic measurement. This function can be switched off if not
required (see man. 6.10.13.2).
7.1 Continuous Measurement of a Measuring Point
As long as no cycle and no continuous measuring point scan have been
programmed (e.g. after a reinitialisation, see 3.3) only the measured value of a
selected measuring point, which is at first M0, is continuously acquired with the
specified conversion rate (see man. 6.5.4). This is the optimal operating mode
for data recording with analogue output.
7.1.1 Selecting the Measured Value and Measuring Point
After switch-on the function MEAS.VALUE and the measuring point M0 of the
first sensor are automatically selected, i.e. the measured value M0 will be
indicated in the display. After selecting other functions using the keys
F1
and
F2
it is possible to return to the display of the measured value by using the key
M/
HOLD
.
In function MEAS. VALUE, the key
M
▲
allows to successively select all
measuring points and indicate the actual measured value. If the key
M
▲
is
pressed longer (approx. 1s) the previous channel is again indicated. By
selecting the measuring channel the input channel is, at the same time, also
selected (see 6.1). If the measuring range changes when switching over, the
abbreviation of the measuring range is indicated first.
