3.4 Mid375 application
3.4 Mid375 application
This section applies if the Mid375 application is enabled. See the Service manual for
information on enabling the applications.
In the Mid375 application the checkweigher mode is always active and the target
weight is always displayed in either gross or net weight. Unlike the Sim375 application
that only displays the deviation from target, the Mid375 application displays the weight.
3.4.1 SELECT key operation
In the Mid375 application, press
SELECT
to cycle through the active display values:
GROSS, NET, TARE and TRANSACTION COUNT. The appropriate annunciator will
light for each display value. (The transaction count annunciator is the green circle
under the right digit on the display.)
3.4.2 Checkweighing
To start checkweighing you need to enter a target weight by using live weight or keying
in the value. By default the lower tolerance (Tol-Lo) is -1 division and the high tolerance
(Tol-Hi) is +1 division. These tolerances can be adjusted. These steps are described in
the following sections.
The ZQ375 adds Tol-Hi and subtracts Tol-Lo from the target weight for over/accept/
under ranges.
Example:
Tol-Hi = 0.1
Tol-Lo = 0.2
Target = 4.0
Target – Tol-Lo = Lower Acceptable Target Limit or (4 - 0.2 = 3.8).
Therefore all weights below 3.8 are considered under weight.
Tol-Hi = Upper Acceptable Target Limit or (4 + 0.1 = 4.1).
Therefore all weights above 4.1 are considered over weight.
This would mean all weights above 3.8 and below 4.1 would be acceptable
as being within target sample tolerances.
Target
Tol-Hi
By default Tol-Lo and
Tol-Hi are 1 division
