IntelliPoint RF RML Series
3.3.1 Quick Calibration
FROM FULL CCW COUNT,
CW UNTIL LED CHANGES
CONTINUE per TABLE 3-1
1. Most water-
based materials
can be considered
conductive, such as
water, acids, bases,
salt solutions, water-
based slurries, and
very wet granular
materials. Carbon
black and powdered
metals conduct even
without any water.
2. With conducting
materials, if
heavy build-up
is anticipated,
calibration
adjustment can
be turned to its
clockwise limit.
Quick Calibration method is ONLY recommended for
horizontally mounted, bare metal, Cote-Shield sensing
elements. In all cases it is necessary to have material level
below the probe (sensing element in air).
Red LED OFF = relay energized = normal condition
1. For either High Level Fail Safe (HLFS) or Low Level
Fail Safe (LLFS) begin with sensing element totally
uncovered.
2. Starting with calibration adjustor in full counter
clockwise (ccw) position, slowly turn clockwise (cw) until
relay just operates. [Red LED will turn OFF in HLFS and
turn ON in LLFS].
3. Note position of adjustor. Turn it clockwise (cw) from this
point the additional number of turns indicated in Quick
Calibration Table 3-1, below.
Calibration is Complete
