Sartorius MW1 Operating Instructions Manual page 41

Application: Counting Z
With the Counting program you can
determine the number of parts that
each have approximately equal weight.
Features
– Enter the reference piece weight
" wRef " via the keypad
– Save the reference weight " wRef
from the weighing platform
– Enter the reference sample quantity
" nRef " via the keypad
– Automatic reference sample updating
– Activate info-mode by pressing I
– Toggle the display between quantity
and weight by pressing W
– Define the resolution (level of accuracy)
applied when a calculated reference
sample weight is stored
– Automatic taring of container weight.
Configuration:
Z:
Appl 3.7.
(autotare first weight)
– Automatic initialization when the
Midrics is switched on. The display and
control unit is initialized with the
most recently used values for reference
sample quantity " nRef " and reference
sample weight " wRef ". Configuration:
Z:
Appl 3.8.
(start app. with last values)
– Closing application program;
deleting parameters:
The value for reference sample weight
remains active in the reference memory
until you delete it by pressing the
c key, overwrite it or until you select
a different application. It also remains
saved after the scale has been switched
off.
– Restore factory settings. Configuration:
Z:
Appl 9.1.
Before the quantity on the platform
can be calculated, the reference sample
(average weight of one piece) must be
entered in the application. This is
known as "initializing" the application.
" There are three ways to enter this value:
– Calculation:
– Place the number of parts defined
as the reference sample quantity
on the weighing platform and press
O to calculate the reference
sample weight
– Alternatively, you can place any
number of parts on the weighing
platform, enter the number of
parts using the keypad, and then
press the r key to calculate
the average piece weight
How the reference weight is calculated
depends on the application setting for
resolution ("Resolution for calculation
of reference value"). The value is
either rounded off in accordance with
the display resolution, or saved with
10-fold or 100-fold increased resolu-
tion or with the maximum internal
resolution of the weighing platform.
– Keypad input: Enter a reference sample
weight (i.e., the weight of one piece)
using the keypad and press O to
save it.
After initialization, you can use the
weighing platform to count parts.
The initial application values are valid
until deleted by pressing the c key,
or until overwritten by new values.
They also remain saved after you switch
off the scale.
– Tare function:
1) If you store a tare (weight value)
by pressing the ) key, you can later
enter a tare value manually. The tare
value you enter is added to the stored
tare value.
Setting: menu code 3.25.1
(factory default)
2) A tare value entered manually
overwrites a stored tare value (weight
value). If you enter a tare value manu-
ally, a tare value (weights value) stored
later overwrites the manually entered
value.
Setting: menu code 3.25.2
