LevelPRO - 

Multiple Tank Level Processor

EX-1803

Specific Gravity Editing

Specific gravity can be entered directly through the user
keypad. Press 

MENU

 to access the “SP.GRAVITY” value

and then 

EDIT

. Now merely enter the 4-digit number

directly (the decimal point is a fixed place holder). Press

ENTER

 to accept the new value and return to the tank

level display.

Selecting Display Units

To change the readout units, use the keypad at the Main
Processor. Press the 

MENU

 key. “SP.GRAVITY” appears

on the display. Press the MENU key again for the
“UNITS” display. Then use the 

SELECT

 key to sequence

through the readout units selections. When the desired
readout unit is displayed, press the 

ENTER

 key to accept

the selection.

Entering Calibration Mode

The “calibration” mode sets the LevelPRO processor to
read directly in A/D counts (0-4096) corresponding to
the milliamp signal input value (4-20 mA). This may be
used during troubleshooting.
