The target deviation method uses a target value in which the upper and lower tolerances are
deviated from the target. The upper and lower tolerances are fixed values. The accept window is
varied by adding the high tolerance to the target and subtracting the low tolerance from the target.
This feature is commonly used in check-weigh applications. The desired target may be based on
gross weight, net weight or quantity (if counting is enabled). The annunciators will light on the
Model 370/375 display or physical setpoints can be added.

Changing Targets From The Weigh Mode (Target Deviation Check-
Weighing)
When Check-Weigh by Deviation is configured in the setpoint setup, the Targ 1 value
automatically becomes an available mode for the [SELECT] key. It is possible to accept the
applied weight as the target. Instead of keying in the target value from Targ 1, press [TARE]
(370) or [SAMPLE/Enter] (375). Press [TARE] (370) or [SAMPLE/Enter] (375) again to accept
the target. Lo and Hi are the subsets for Targ 1. Lo and Hi are entered as actual values.
To change target to 10 from the Weigh Mode:
1. From the weigh mode press [SELECT] until targ1 is shown on the display.
DISPLAY READS Targ1 ~15.00
2. Press 10 [TARE] or [SAMPLE/Enter] to set a new target. Either press [SELECT] to go to the
weigh mode or go to step 3 to access the low tolerance parameter.
DISPLAY READS Targ1 ~ 10.00
