2.3 Description

The model DI35 digital indicator is a multi-function and very accurate instrument for a wide variety of measuring tasks.

The DI35-D is equipped with two inputs for standard signals (0/4 … 20 mA and DC 0 …

10 V) that can be used in any combination. The display can show one of the two input signals or a calculated value. Calculations can be made by means of the four basic arithmetic operations (+ - * /) and an additional constant multiplier.

In addition, both versions offer the possibility to calibrate sensors and linearise using up to 30 points. This allows further adaptation of the displayed 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.

6.6 Switching the display between measuring inputs

The switching of measuring inputs changes between the display values of the measuring inputs and the display value of the arithmetic calculation. The display value of the arithmetic calculation is only displayed when this has been configured.

The following methods are supported:

Method

Static

Triggered

Cyclic

Description

A preset display value is shown for the duration of the trigger signal.

With each trigger pulse, the measuring input is switched further (series Ch1, Ch2, Ar).

The change is made cyclically over a preset time interval

(series Ch1, Ch2, Ar).

For the trigger signal, the multi-function button or the digital input can be used (for programming, see chapter 7.6 “Switching of measuring inputs”)

Before each change, the description of the measuring input is displayed.

7.2.2 Switching of measuring inputs

The switching of measuring inputs changes between the display values of the measuring inputs and the display value of the arithmetic calculation. The display value of the arithmetic calculation is only displayed when this has been configured.

The following methods are supported:

Method

Static

Triggered

Cyclic

Description

A preset display value is shown for the duration of the trigger signal.

With each trigger pulse, the measuring input is switched further (series

Ch1, Ch2, Ar).

The change is made cyclically over a preset time interval (series Ch1,

Ch2, Ar).

For the trigger signal, the multi-function button or the digital input can be used (see chapter 7.7 “Setting special inputs”, PN 53/PN 54)

Before each change, the description of the measuring input is displayed.

7.7.3 TARE function

The TARE function sets the display value of the stored measuring input to zero. The difference between zero and the display value is stored as an offset value.

The TARE function overrides a previously programmed offset shift of the measuring inputs (PN 4/9). Should the TARE function be used during a measurement, the offset shift has to be reprogrammed.

The TARE function can be activated through the multi-function key or the digital input

(→ see chapter 7.7 “Setting special functions”). The key must be activated for at least 3 seconds.

The tare operation is represented as follows:

7.9 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 assigned a new display value manually.

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.

140 Number of interpolation points, measuring input 2 0 ... 30

141 ... 170 Display value for interpolation point, measuring input 2 -9999 ... 99999

Procedure

1. Set the number of interpolation points under PN 100/PN 140.

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.


4. Repeat steps 2 + 3 for all interpolation points.

⇒ Input signal is linearised.
