Scaling - Ahlborn ALMEMO 710 Operating Instructions Manual

On page 4 we are offered, as alternative, the option of using the output cycle
(see 10.1.3) for recording data to memory. This will be used to always output
all channels - unless the cycle is prolonged by the cycle factor (see 10.1.3.1) or
certain channels are even deactivated.
On page 5 we are offered the option of sleep mode for long-term recording; in
this mode the device is switched off completely between cyclic scans, thus en-
suring a much longer operating time per battery charge. To ensure that lower-
speed sensors also have time to settle and deliver correct measured values, a
sleep delay time will be set - normally automatically; this parameter is also
saved in the sensor connector.
On page 6 the display shows the remaining memory capacity, the probable
memory time, and the battery operating time subject to the present configura-
tion.
If the remaining memory capacity is insufficient, either the memory can be
switched to ring mode or an external memory connector with an SD card can
be used.
If the remaining battery capacity is insufficient, the battery must be fully
charged or the mains adapter must remain connected or sleep mode with its
longer cycle must be used.
On pages 7 and 8 we can set 2 limit values (see 13.2.7) per measuring chan-
nel and choose from various actions (see 13.2.8) to be triggered in the event of
these limit values being infringed. A limit value infringement can be used not
only to issue an alarm report or alarm message but also to start / stop an entire
measuring operation. Via macros the device's whole command repertoire can
be used.
On page 9 we are offered further possibilities for starting / stopping a measur-
ing operation. The necessary control signals include not only keys, times, limit
values but also mechanical or electrical events received via trigger modules.
Finally we may need at a later date or time to identify, locate, and interpret
some previously recorded data. With this in mind on page 10 we can enter a
comprehensive comments text describing the particular measuring location,
purpose, task. Certain measured values or certain series within a measuring
operation can also be assigned a number on the basis of which they can sub-
sequently be called up very quickly.
On the last page we are given an overview of all the most important parame-
ters.

14.2 Scaling

To display the electrical signal of a sensor as a measured value with a physical
quantity it is usually necessary to perform scaling with a zero-point shift and
factor and often a decimal point shift as well. (see 13.2.11)
To help calculate all the necessary parameters we have the ´Scaling´ wizard.
Here you should enter 2 corresponding points as actual value and setpoint and
select the desired decimal position and the units.
