Operation
Zero indication and zero adjustment
A basic zero setting of the gross weight for unloaded scale is performed at installation
as a part of the calibration. When a ‘good zero’ is displayed, the text ‘Zero’ is shown
to the right in the display.
Minor correction of the zero value may be needed and can rapidly be performed.
Zero adjustment
If, for unloaded scale, the text ‘Zero’ is not shown, but the gross weight is
close to zero, a rapid zero adjustment can be performed.
The gross weight must be stable (text ‘Motion’ not shown) and the key ZERO
must be enabled.

Taring
Taring means storing of a tare value for the scale. Net weight will be calculated as
the difference between the gross weight and this tare value. If the tare value is zero,
net weight will not be displayed.
At default setting, taring can always be performed, provided the key TARE is enabled.
But the scale can also be set to allow taring only at stable weight (when the text
‘Motion’ is not shown).
In G4 two tare values can be used: Auto tare and Preset tare.
Auto tare
By taring, the actual gross weight is stored as Auto tare value, and the scale will switch
to display of net weight ‘zero’.

G4 Multi Channel Weighing Instrument
Basic set-up
General
All operating functions in G4 are controlled by parameters, stored in the instrument
memory. The actual setting of the parameter values can be edited during normal
weighing operation, using the touch display and the keys on the front panel.
WARNING. Changes done during editing of set-up parameters will affect the
behaviour of the instrument immediately. The user must take all necessary
precautions to prevent any undesired effects in process monitored or controlled
by the G4 instrument or a connected control system.
It is strongly recommended to activate the set-up lock in the instrument to prevent
any unauthorized changes of set-up parameters.
This section proposes a number of parameters to set, that will rapidly give
the instrument a useful presentation mode and basic measuring properties.
It contains setting of, for example, the measurement unit and resolution for
the weight value, and also some parameter settings for data sheet calibration
and deadweight calibration in two points.
If you are dealing with an already working instrument we recommend that you perform
a backup of the set-up parameters before you make any changes to the instrument.
When the set-up is finished, all parameter values should be noted (see appendix 1
and 2), or backed up in a file. Backup to an USB memory (or internal file) can be done
from menu 'Maintenance', sub menu 'Create Backup'.
Appendix 1 and 2 to this manual contains suitable forms to fill in for the instrument
hardware configuration and for the set-up parameters, covered by this manual.
Hardware configuration
The instruments G4, types PM/DT/HE, have room for one fieldbus module and six
other modules. The configuration of installed modules, used measuring channels,
and scale numbers is made in set-up parameter menu 'Hardware Config.'.
At delivery of an instrument, the hardware configuration normally corresponds to
the set-up. If any mismatch between installed modules and hardware configuration
occurs, an error message will be shown at instrument start-up.
Consult 'G4 Multi Channel Weighing Instrument Technical Manual PM/DT/HE types'
if you need to change the hardware configuration.
Security lock
With an instrument G4 it is possible to perform set-up operations during normal
operation, which may influence for example the performance of a scale. To prevent
these dangers, the instrument is equipped with security locks at two levels that can
be activated to protect from unauthorized access to editing of parameters and values.
Four-digit codes for the locks can be defined by the customer.
By default setting the code for both locks is: 1 9 3 7 .

Data sheet calibration
This calibration method can be used when data sheets for the transducers are
available and no external forces influence the weighing installation.
If fixed supports are included, the load must be evenly distributed on all supports.
Data sheet calibration can be performed without any transducers connected,
but the transducers must be connected as the zero setting is performed.
A data sheet calibration for a scale should start with the scale parameters,
described on page 28.
This example shows a Data Sheet calibration for Scale 1.
When data sheet calibration has been selected
and you have accepted to start a new calibration,
menu 'Scale 1 Calibration' will be displayed again.
Use arrow keys 'up' and 'down' to select a parameter
to edit, then press 'Enter' to accept.
All parameters are explained below.

Operating instructions, Quick installation
Zeroing of gross weight
When the scale installation is calibrated, a zeroing is performed in order to get
the gross weight zero when the scale is unloaded. If mechanical equipment is added
later, this will affect the weight display for the scale, and a new zeroing of the gross
weight becomes necessary.
NOTE!
The scale must be unloaded when zeroing is performed.
Access ‘Set Zero' for any calibration type.
Navigate to menu 'Calibration' and select
the desired scale, in this example 'Scale 1'.
The sequence is described on page 27.
In menu 'Scale 1', use arrow key 'down'
to position the indicator at the bottom line:
'Scale 1 Calibration'.
Press 'Enter'.
In menu 'Scale 1 Calibration', use arrow key 'down'
to position the indicator at line '1:Set Zero'.
Press 'Enter'.
