The instrument regards the distance (DIST) measured from the antenna end as the
basic measurement value. This distance is handled and display in one of the
selected dimensions: m, cm, mm, feet, or inch. Since the maximal measurement
distance is given (entered in P04) the instrument can calculate the actual level
(LEV) value. If the proper mechanical dimensions of the mounting – distance
between the sealing and the tank bottom – is known, the measured level values
can be more accurate by adding this data. The level values calculated that way are
the base for volume (VOL) calculation and the 99-point linearization table (VMT)
also uses these values as input data.
8.1 The NRM-300P display unit
8.1.1 Primary measurement screen
The NRM-300P is a 64x128 dot-matrix LCD display which can be plugged into the
transmitter. (It is universal – usable in other Kobold devices as well – provided that
the system software supports NRM-300P.)
Warning! The NRM-300P module is based on LCD technology, so please
make sure it is not exposed to permanent heat or direct sunlight, in order to
avoid damage of the display unit. If the instrument cannot be protected
against direct sunlight or high temperature that is beyond the standard
operating temperature range of the NRM-300P, please do not leave the NRM-
300P display in the instrument.
Measurement displaying with the NRM-300P display unit
Elements of the displaying:
1. Primary (Measured) Value (PV), in accordance to BASIC
SETUP / PV. MODE.
2. Calculation mode of Primary Value (PV), in accordance
to BASIC SETUP / PV. MODE.
3. Type and value of the initial quantity used for calculating
the Primary Value (PV):
- in case of Level measurement (LEV) it is
Distance (DIST),
- in case of Volume measurement (VOL) it is
Level (LEV).
4. Trend direction arrows. The empty triangle
shows when the change of the measured value is
small, the filled triangle shows large-scale
change. If none of the arrows are shown the
measured value is constant.
5. Measured PV (Distance Value) in relation to
measurement range (Sensor range) displayed in
a bargraph.
