Counting Z
Purpose
With the Counting program you can
determine the number of parts that
each have approximately equal weight.
Available Features
– Reference sample quantity "nRef"
loaded from long-term memory when
you turn on the balance
– Optional balance configuration in the
Setup menu for automatically initializ-
ing this application and loading the
most recent reference sample quantity
"nRef" and average piece weight "wRef"
when you turn on the balance (auto-
matic initialization; menu code 3 10 1)
– Minimum load checked when the
balance is initialized (factory setting:
10 display increments; can only be
changed by the Sartorius FastFactory)
– Reference sample quantity "nRef"
entered using the keys
– Average piece weight "wRef" entered
using the keys
– Storage parameter (level of accuracy
with which the average piece weight
"wRef" is stored) for piece count calcu-
lation can be configured
– Optional configuration for having the
piece count and average piece weight
output automatically via the data inter-
face port after initialization or reference
sample updating while running the
Counting program (print application
parameters)
– Long-term storage of the last reference
sample quantity "nRef" entered
– Long-term storage of the last average
piece weight "wRef" entered with the
corresponding reference sample quantity
"nRef," by configuring automatic
initialization
– Toggling between two weight units by
pressing w
– Counting program initialized again
after using the balance for weighing
(after initialization)
Factory Settings
Auto-start application (automatic
initialization with reference sample
quantity and average piece weight
loaded from long-term memory):
off (3 10 2)
Counting/percent parameter (accuracy
when storing average piece weights):
display accuracy (3 5 2)
Printout application parameters
(automatic output of application
parameters): off (7 1 1)
Preparation
To calculate a piece count, the average
weight of one piece must be known.
This average piece weight can be
entered into the Counting program in
one of three ways:
– The last reference sample quantity
entered is loaded and displayed when
you turn on the balance. Place the same
number of parts on the balance and
initialize the counting program;
– With automatic initialization switched
on, the balance goes into the "counting"
mode when you turn it on and loads
the last average piece weight and corre-
sponding reference sample quantity
that were entered or calculated;
– Enter the average piece weight using
the numeric keys and store it.
Reference Sample Updating
When the updat soft key is displayed
during counting, this means you can
have the average piece weight updated
(while the piece count is displayed in
the measured value line).
The updat soft key is displayed when:
– the balance has reached stability
– the current piece count is less than
double the original piece count
– the current piece count is less than 100
– the internally calculated piece count
(e.g., 17.24 pcs) differs from the nearest
whole number (here: 17 pcs) by less
than 0.3
Reference sample updating can be
repeated several times with an approxi-
mately doubled piece count.
To perform reference sample updating:
Press v (updat soft key)
Turn on the balance: Press e
> All display segments light up briefly
Select the Counting program in the
Setup menu: Press M
Select menu:
Press the menu soft key (w)
Set parameter 2 1 4:
