Proceeding with factory
calibration PN0 ≤12
With adjusted factory calibration a linearization without connection of the
sensor signal can be presetted. Therefore the number of the desired
setpoints needs to be filled in under PN100, to subsequently relate the
display values to a certain measuring signal.
Starting on setpoint (PN101) the display value (SCALE) and subsequently the
according measuring signal (INPUT) need to be programmed. Both inputs are
saved by pushing the [P]-key (for approx. 1 sec).
6.6 Description of the program numbers
The DI35-M device has a default configuration ex factory, where a 0…10 V
input signal is changed into a display value of 0…10000. For devices, where
the pre-configuration is unknown, a reset on the default parameter should be
done (see chapter “6.8 Default values”). Otherwise unwanted reactions of the
device can occur due to foreign settings.
The devices do have a digital input, with which some functions like e.g.
HOLD, TARA, or MIN/MAX can be actuated.
PN0: Measuring input
For the basic configuration of the unit, you must parameterize the right
measuring input for your application under PN0. There is a choice of various
inputs in the program number table (chapter „6.7 Program number table“).
PN1 and PN2: Scaling
The two program numbers 1 and 2 serve to scale the display; with these two
parameters, the offset and full scale are parameterized . For each setpoint
there is a SCALE–value and a INPUT–value. The SCALE–value indicates the
desired display value. The according measuring signal is determined by the
INPUT–value. In case of factory calibration the desired current or voltage
value is preset. If a sensor calibration is demanded, a measurement can be
actuated by a short pushing of the [P]-key. Before the saved current / voltage
value is visible. All inputs need to be confirmed by pushing the [P]-key for
approx. 1 second; the device confirms the correct take-over with 5 vertically
bars in the display.
PN3: Decimal point
By changing this parameter, the position of the decimal point in the display is
changed. With temperature measurements, the physical unit °C or °F can
also be added.
