7. MEASUREMENT
The instrument ALMEMO
®
2290-8 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.
Total Clearing of all Measured Values
Previous measuring data should be cleared before a measurement. Max, min,
and average values of all channels and the memory can be cleared with the
rotary switch in position MEMORY, by using the keys

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 CH0, is continuously acquired with
the specified conversion rate (see 7.3.3) (optimal for analogue output).
7.1.1 Selecting the Measuring Point
With the rotary switch moved to position MEAS. VALUE, 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.
