Neutral Measurement
Z
nM
(Combics 2)
With this application you can measure the length, surface and volume of parts that
have roughly the same specific weight. The o symbol is displayed as the unit (menu
APPLIC.1
).
Features – Save the reference weight “wRef" from the weighing platform:
– Enter the reference weight “wRef” through the keypad
– Enter the factor for calculation “nRef” using the keypad
– Enter reference sample weight using a barcode scanner
– Measuring with two weighing platforms
– Activate Info mode with the
I
key
– Toggle the display between measurement and weight via the
w
key
– The level of accuracy (display resolution) can be set when the calculated
reference weight is applied
– Automatic taring of container weight
Setting:
Applic. / aut.tare
, menu item 3.7
– Automatic initialization when the scale is switched on. The indicator is
initialized with the most recently used values for reference sample quantity
“nRef” and reference sample weight “wRef.”
Setting:
Applic. / aut.strt
, menu item 3.8
Exit application, delete parameters
The value of the reference sample weight in the reference memory remains active
until it is deleted via the
c
key or overwritten or until the application is changed.
The reference sample weight also remains saved after the scale is turned off.
You can assign different functions to the
c
key for deleting applications. When
you clear applications, you can delete either the data stored for all applications or
just selected data stored for the active application.
Setting:
Applic./CLER.CF
menu item 3.24
Tare function:
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:
Applic. / TARE.FNC
menu item 3.25.1 (factory setting)
A tare value entered manually overwrites a stored tare value (weight value). If you
enter a tare value manually, a tare value (weight value) stored later overwrites the
manually entered value.
Setting:
Applic. / TARE.FNC
menu item 3.25.2
Restore factory default settings:
Applic./Reset
menu item 9.1.
Reference weight
In order to calculate the length, surface or volume of a given sample, the average
weight of a reference quantity of the sample must be known (in the example below,
the reference is 1 meter of electrical cable). There are different ways to enter the
reference weight:
Calculating the reference weight
– Place the reference quantity (defined by the calculation factor) on the connected
weighing platform and calculate the reference sample weight by pressing the
O
key.
or
– Place any amount of the sample material on the connected weighing platform,
enter the calculation factor through the keypad, and press the
r
key to
calculated reference sample weight.
How the reference weight is calculated depends on the application setting for
