CHECK OUT PROCEDURE

As you go through this procedure, if WHAT SHOULD HAPPEN, doesn't happen, see the next section, DIAGNOSTICS, for what to check.

NOTE: 100 and 200 series models (3K load cells), display all weight

readings in 1/10 grams ( x.x). 400, 900, and 1800 series models (10K load cells) display in FULL grams, no decimal.

On this page we show all weight readings WITH a decimal point.

Start with NO MATERIAL in any hoppers. Be sure an AIR SUPPLY is connected.

Place ALL switches DOWN; POWER (on front); STOP and PAUSE (on left).

	This means all air cylinders are extended. If any
	slide gate or flap is open, air lines are
	reversed.
TURN POWER ON.	Display should show ( FOUR		), software type,

	followed by (	0.0),
	followed by the actual weight of material in the

	or full grams	depending on your model.
