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

STEP 1: LEVL (Level)

1. From the RUN mode, press the 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

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

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

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

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

to display BARE.

2. If this is the type of probe in use, press ENT

Step 4, TDLO will be displayed.
