2. Design and function
2.2 Description
The model DI35-M digital indicator is a multi-function and very accurate instrument for a
wide variety of measuring tasks.
In addition, both versions offer the possibility to calibrate sensors and linearise using
up to 30 points. This allows further adaptation of the display values to different sensor
signals and application requirements. The standard features are completed by a transmitter power supply, a HOLD function and a TARE function for the correction of offset
shifts and sensor drifts. The sampling rate and display time can be configured and the
display can be dimmed. Unauthorised alteration of the set instrument parameters can
be prevented via different user levels, in conjunction with a freely selectable access
code.
Optionally available are up to four freely configurable switch contacts, an analogue
output signal and a serial interface.

cabling to the measuring instrument can be made with simple copper
cable.
7.1.6 TARE function
The TARE function sets the display value to the set value of the taring. The difference
between the set point and the display value is stored as an offset value (PN5).
The TARE function overrides a previously programmed offset shift (PN5).
Should the TARE function be used during a measurement, the offset shift
has to be reprogrammed.
The TARE function can be activated through the following points under PN8.

7.2.2 Refresh rate
The refresh rate determines how often the display values are updated. With strongly

and other functions are not affected.

7.2.1 Running averaging
The total averaging time is given from the multiplication of the measuring time (PN14)
and the registered averaging value (PN12). If one wants to see the running average on
the digital indicator, the display mode (PN15) must be programmed accordingly. This
must also be observed for the optional analogue output or with the switching outputs.
7.2.3 Measuring time
The measuring time determines how often the analogue and switching outputs are
updated. With strongly fluctuating input signals, it is recommended that the measuring
time is adjusted (measuring time > 0.2 ... 1s).

The updating of the analogue and switching outputs is made cyclically
with the set measuring time. If the measuring time is set very short, this
can, with an unsteady input signal, lead to jumps with analogue outputs
or to short switching of the switching outputs. The MIN/MAX memory
receives the values on the basis of the set measuring time. Should
the peaks in an unsteady input signal need to be determined, a short
measuring time can be useful.

The analogue output can be assigned any measuring input. The output signal is
updated simultaneously with the measuring input. The refresh rate is determined by
the configured measuring time. The start and end value for the analogue signal can be
assigned user-defined measured values.
The start and end values define at which display value the minimum and maximum

The authorisation levels can only be changed if the release code corresponds to the
locking code (password protection). On delivery, both parameters are set to the value
0000, whereby the programming lockout is deactivated.
The control level is selected via PN53. The simple control level serves as the basic
setting. Only those program numbers which sufficiently enable the digital indicator to
be put into operation are displayed. With this, the assigned start and end values for
the measuring signal are automatically transferred to the analogue output. (→ For the
accessible program numbers see appendix “Program number table”)
The professional control level allows access to all program numbers and enables the

7.7 Linearising sensors
Non-linear sensors can be linearised with up to 30 interpolation points per measuring
input.
At each interpolation point, the input signal is manually assigned a new display value.
The analogue output is also linearised since it is proportional to the display values.
Each interpolation point must have a higher input signal than the previous. The corresponding display values can be freely assigned.

2. Apply the input signal for the first interpolation point, PN 101/PN 141, at the
measuring input.
3. Set the desired display value under PN 101/PN 141.
⇒⇒Input signal is associated with display value.
4. Repeat steps 2 + 3 for all interpolation points.
⇒⇒Input signal is linearised.

For PN 101 this means:
With a pressure of 15 mbar, the transmitter delivers an output signal of 3.3 mA instead
of 3.0 mA. Therefore, before correction, the display shows 16.5 mbar. This value is
adjusted to 15.0 mbar using the interpolation point.

7. Description of the program number
7.8 Totaliser function
The totaliser function sums measuring results which are determined as the result of a
programmable calculation. The measuring results are summed until a reset is carried
out.

181
Time basis of the display value
0 = second
1 = minute
2 = hour

00000 ... 0.0000
180
Totaliser function
0 = off
1 = t otaliser function without permanent storage (reset on restart)
2 = t otaliser function with permanent
storage
In order to calculate a totaliser value, the time basis and the unit are of particular
importance. The flow is defined in volume per time and the speed with distance per time.
Through parameterisation of the time basis (PN181), the totaliser value is summed.
Example
If a sensor measures 1,200 l/h, with a measurement time of 1 s, one must only sum a
3,600th fraction of the litres counted, which, in this case, would be approx. 0.333 litres
per measuring cycle. Despite this very small size, the totaliser value can sum up to an
extremely high value within a timespan of one year. In this example, that means there
were approximately 10,512,000 litres in one year.
An indication in cubic metres would be useful here. In order to realise this, one must
define a factor - in our example PN182 = 3 (10-3). With this, the value in litres can be
converted into cubic metres.
If one only wishes to integrate the quantity only over one month, one can still add a
decimal point to the visualisation as cubic metres under PN183.
If one now parameterises the factor PN182 = 2 and the decimal point PN183 = 1, this
would lead to a display of 864.0 cubic metres at the end of a month.
