METHOD III: SCALING BY SIMULATING A KNOWN LOAD WITH THREE OR
MORE DECIMAL POINT POSITIONS.
An end user has a 3 inch of water pressure transducer with a
4-20 mA output. The end user wants to display in ten thousandths
of an inch of water (desired display 0.0000 to 3.0000). Proceed to
Section 8.3 performing A, B and C sections.

shown below:
Pressing the ‘MENU’ button will step you through all the different
menus listed below. When you wish to enter a menu, to the
submenu 1 stage, press the ‘MIN’ button. To make a selection, in
submenu 1, press the ‘MAX’ button. If the submenu has more than
one item to select press the ‘MIN’ button to scroll to the next item
of choice and again press the ‘MAX’ button to make your selection.
After making all your choices, in submenu 1, enter these selections
by pressing the ‘MENU’ button which will momentarily flash
“STORED”, on the display.
If the item selected in submenu 1 has a submenu 2 associated with
it, press the ‘MIN’ button to enter the submenu 2. Select your
choice by pressing the ‘MAX’ button and enter your choice by
pressing the ‘MENU’ button.
Pressing the ‘RESET’ button one time brings you back one menu,
pressing it a second time returns you to the run mode.
WARNING! this also results in a hard reset of your peak and valley
