2.3.2 Program Path 2 — Single Point
The single point program is for single point, alarm only
applications and allows for proper calibration without level
change. The following procedures must be followed if
SING (single point) has been selected in Program Path 1
CNFG (configuration). When in need of an adjustable set
point (vertical probe only), use MULT (multi-point).
From the RUN display, press ENT ^ENT .
STEP 1: LEVL (Level)
RUN
1. From the RUN mode, press the ENT ^ENT key to enter this
menu. The display will read LEVL. LEVL refers to the
condition of the probe DRY (not covered with media) or
WET (covered with media).
2. Press ENT ^ENT to display DRY.
3. Using the UP and DOWN arrow keys, toggle
between DRY and WET until the display reads the current
condition of the probe.
4. Press ENT ^ENT to store this value. The display will read
MDIA.
STEP 2: MDIA (Media)
1. MDIA (media) refers to the conductance n(dielectric) of
the process media. Press ENT ^ENT to display NONC
(non-conductive).
2. Using the UP and DOWN arrow keys, toggle
between NONC (non-conductive) and COND (conductive)
until the display reads the appropriate condition of
the media.
3. Press ENT ^ENT to store this value. The display reads PRBE.
NOTES:
1. This procedure sets the sensitivity appropriate for the applica-
tion: NONC = 0.5 pF COND = 10 pF.
2. If the conductance of the medium is unknown, choose NONC
(non-conductive) for greatest sensitivity.
3. When calibrating for media in non-metallic (ungrounded) ves-
sels, choose NONC (non-conductive). This will establish the
highest sensitivity (0.5 pF).
STEP 3: PRBE (Probe)
1. PRBE (probe) selects either an insulated or bare probe.
When PRBE is displayed, press ENT ^ENT to display BARE.
2. If this is the type of probe in use, press ENT ^ENT .
Step 4, TDLO will be displayed.
