2. If the PRLO point is to be calibrated, press ENT ^ENT
to display the present value.
3. Use the UP arrow key to scroll to the exact level of
the media, in any unit of measurement (inches, feet,
percentage, etc.), being consistent to use the same unit of
measurement throughout theprocedure.
4. Once the exact unit is reached on the display, press
ENT ^ENT to store the information in memory. The display
will read PRHI (probe high). Raise the process level to a
PRHI calibration point.
NOTE: If entering different PRLO/PRHI points for greater accuracy,
be sure that the new PRLO point is lower than the existing
PRLO point and the new PRHI point is higher than the exist-
ing PRHI point.
5. Press ENT ^ENT to display the present value. Scroll to the
exact level of the media and press ENT ^ENT to store the
information in memory. The display will read PRLO
once again.
6. Press the UP arrow key to leave the CAL mode
and return to the RUN mode, MAGNETROL INTL
M M M.
Probe calibration is complete. Proceed to Section 2.4.3,
Program Path 4 — Multi-Point.
2.4.2.1 Probe Calibration Tips
If you mistakenly get into the wrong area of the program
(for instance, PRLO data when PRHI data was intended),
remember, pressing all the three tactile feedback keys
(ENT/UP/DOWN ^ENT
arrows) simultaneously will
return you to the RUN mode.
After establishing the probe low point (and the unit times
out from the CAL mode to the RUN mode while raising
the level for the probe high point), DO NOT press
ENT ^ENT after returning to the CAL mode when PRLO
appears. Press the UP arrow key to bypass PRLO and
obtain PRHI. This will avoid setting the PRLO point
where the PRHI point should be.
If you get lost, and the unit continually displays ERROR
messages (2LO or 2HI, etc.), do the following:
1. Return to the RUN mode by pressing the DOWN arrow
(from PRLO) or the UP arrow (from PRHI).
2. From the RUN mode, press the ENT ^ENT and the UP
arrow keys simultaneously ( ^ENT ) to enter the menu.
The display will read CNFG.
