7. MEASUREMENT
The measuring instrument with built-in printer ALMEMO
®
6290-7B provides the
following options for the acquisition of measuring data:
1. Continuous measurement of a selectable measuring point, see manual 6.4.
Output of measuring data to the analogue output see manual 5.1.1.
2. Single measuring point scan, see manual 6.5.1.1.
3. Cyclic measuring point scan, see manual 6.5.1.2.
4. Continuous measuring point scan, see manual 6.5.1.3.
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 3.4) only the measured value of a
selected measuring point, which is at first M0, is continuously acquired with the
specified conversion rate (see 6.5.4) (optimal for analogue output).
7.1.1 Selecting the Measuring Point
With the rotary switch moved to position MEASURE, the key
CH ▲
allows to
successively select all measuring points and indicate the actual measured
value. If the key
CH ▲
is pressed and held (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.
Increase measuring channel with key:

In case of a sensor breakage the abbreviation for the
meas. range flashes instead of the meas. val. (s. 6.2):
The arrow ´
CORR
´ is illuminated in the display if the measured value is
corrected by scaling or correction values (see 5.1).
