RDG SC= display span/((sensor’s mV/Voutput) (natural gain))
RDG SC= 200/(10 x 10000) = 0.002
Where: display span= 200 – 0 = 200
Sensor’s output = 100 mV/10V EXC =10 mV/V
Meter’s natural gain= 10000 (Obtained from Table 8-1)

Pressing the ‘MENU’ button will take 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 use the ‘MIN’ button to scroll to the next item of
choice and again use 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 go to
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’ item,
pressing it a second time returns you to the run mode.
WARNING! this also results in a hard reset of peak and valley and
your setpoints.
Proceed through the flow chart below entering the values listed in
submenu 1 and 2 columns.
