APPENDIX E: Addendum for 4-20 mA Option

GENERAL INFORMATION

Some models provide a passive analog 4-20 mA output on two terminals. These terminals are
covered in Chapter 2

The output tracks the weight displayed on the indicator, so you must first have the indicator
configured and calibrated correctly in order for it to work properly.

Here is a working connection diagram used at the factory to test:

NOTE 2

: The AA (4-20A) and BB (4-20B) wires are not polarized. You may connect them in any

manner you wish.
