Very Important!
- Changing Pntvalue reflects
the real value of all parameters
with input value dimension!
E.g:. Changing Pntvalue from
(х1) to (х0.1) would change the
offset value from 100 to 10.0!!!
88950400 is a small-sized and low-cost
programmable display for panel
mounting and 24 VDC power supply.
88950400 accepts linear voltage
signals and allows programmable
digital indication of the measured value
from 0000 to 9999 units with movable
decimal point.
Place 88950400 into a 71 x 20 mm
panel cut-out and tighten into place
using the enclosed mounting bracket.
Basic Operating Level
After power on 88950400 enters 'basic level' displaying measured value according to the preset parameters.
Parametric Level
Press and hold
until PAr appears. View parameters (see below) with
♦
Point Position
- Defines display decimal point position. Affects all parameters with input value dimension (!)
♦
Input Low - Defines display value at 0 V input
!
♦
Input High - Defines display value at 10 V input
!
♦
Display offset - Adds a constant to the display value
!
♦
Filter Time - Relative time of the input low-pass filter
♦
Filter Band - Relative band of the input low-pass filter
♦
Display Refresh - The time between two subsequent display measurements
♦
Display Brightness - Defines display brightness level

Setting numerical parameter value
After entering numerical parameter adjustment, select the flashing rightmost digit by pressing
. The 3 rightmost digits can accept values from 0 to 9, and the leftmost digit can also accept the values - and `.
value using
Confirm the adjusted parameter value by pressing the key combination
adjustment completes, and the display shows the next parameter, or, in case of wrong value entered, the display shows the wrong
value and waits for correction. If the new value has not been confirmed and no key has been pressed for a certain period of time,
value adjustment automatically ceases, and the parameter retains its initial value.
Setting symbolic parameter value
A
fter entering symbolic parameter adjustment mode, read the flashing parameter value on the display and change it using
Confirm by pressing the key combination
certain period of time, value adjustment automatically ceases, and the parameter retains its initial value.
