MEASURING MENUS
In addition to the universal sensor display (see below) the measuring points
list menu
(see 11.4) also offers a useful overview of all measuring channels in
combination with the most important data. Each measuring menu can, by means
of function menus, be assigned various functions; (see 12). If these preconfig-
ured menus do not completely meet your requirements, you can assemble your
own user menu U1 from a range of over 50 functions; (see 11.6).
11.1
Menu Sensor display
When the device is switched on for the first time
it opens with the intelligent menu
Sensor display
.
The first line shows the measuring point, meas-
ured value, and units - in upper-case format. Be-
low this, depending on the measuring range, it lists
all functions of importance for this measured
value, plus any further measuring channels as-
signed to the connector in question.
Symbols indicate the status of the measured value; (see 9.2).
Additional measuring functions are provided via function menus; (see 12).
Symbol
<M>
in the middle of the row of softkeys indicates that the measuring
point can be selected by pressing keys ▲ and ▼.
11.1.1
Selecting a measuring point
By pressing key

you can select one after the other all active measuring
points and have the current measured value displayed for each. By pressing

you can move back to the previous channel. When a particular measuring
channel is selected the associated input channel is also selected at the same
time.
To increment the measuring channel press

.
To decrement the measuring channel press

.
11.2
Measured value correction and compensation
To achieve maximum measuring accuracy zero-point correction and, partly at
least, gain adjustment can be performed for sensors as early as the
Sensor dis-
play
menu. For all sensors with 2 actual values and 2 setpoint values universal
two-point adjustment is provided via the function menus
Two-point adjustment
(see 12.3) and
Scaling
(see 12.4). For sensors dependent on ambient tempera-
ture or atmospheric pressure the appropriate compensation parameters are pro-
vided as early as the
Sensor display
menu; (see 11.2.4 and 11.2.5).
