The Measured Value menu is used to display
current values being measured by the Sentinel II
(refer to page 15 for the overall menu layout).
Follow this step-by-step procedure to use this
menu. It is assumed that you are starting from
the RUN mode.

NOTE: A minimum level change (2% of span) is
required; however, a greater differential will
improve accuracy. Two calibration points will
be entered: Cal Pt. #1 (LO) is the lower point;
Cal Pt. #2 (HI) is the upper point. They may
be entered in any order.
If it is easier to raise the level in your vessel,
set “Cal Pt. #1 (LO)” first; raise the level a
minimum of 2%, then set Cal Pt.
#2 (HI)”. If it is easier to lower the level in your vessel,
then set “Cal Pt. #2 (HI)” first; lower the level a mini-
mum of 2%, then set “Cal Pt. #1 (LO)”.
These calibration points do not have to correspond
with the 4–20 mA output settings or any discrete out-
put set point; they are two arbitrary points along the
length of the probe.
