Service panel
General
The service panel VIEWPAN features a two-line, back lighted LCD-display and four
function keys. It can display the weight or flow value, or other selected information,
for one scale at a time.
It is also possible to connect a standard USB keyboard for PC to the USB connector
at the CPU module. The keyboard will work in parallel with the keys on VIEWPAN and
will make it easier to handle the configuration of the instrument, as it can be used as an
input for digits and characters.
The keyboard keys ' + ', ' – ', ' ↑' or 'Esc', and 'Enter' will correspond the VIEWPAN
keys ' + ', ' – ', ' ↑' , and ' ↵'.
Function key 'F11' on the keyboard can be used to access the 'Main Menu'.
Display
During measuring operation the function
keys + and – are used to toggle G4 RM
between display of measured values for
the scales in the instrument.
As G4 RM is in measuring operation
the top line shows a weight or flow value.
The bottom line, to the left, indicates
the actual scale number (S1:, S2: etc.),
and information about the measured value
(G=gross weight, N=net weight, M=motion,
Z=zero, Flow=flow display).

Additional functions
During measuring operation the additional functions for a scale that are activated
in the parameter set-up can be displayed to the right on the bottom line.
Key ↑toggles the display of additional functions 'on' and 'off'.
As the additional functions are displayed, the keys + and – will perform
scrolling of the additional functions that are available for the scale.
Possible functions are: Tare, B/N, Print, Zero, Levels, Pre.Tare, W/F.
See explanations of the functions below.
As key ↵is pressed, the displayed additional function will be performed
and display of additional functions will be toggled 'off'.
Explanations of the additional functions
Tare: This function performs taring, which means storing of the actual gross weight
as auto tare value and switching over to display of net weight.
Net weight being the gross weight minus tare.
B/N: This function performs toggling between display of gross weight, indicated by G,
and net weight, indicated by N.
Net weight cannot be displayed if the tare value in use is zero.
Print: This function initiates a print out of the displayed weight value.
Zero: This function performs Zero adjustment, a zeroing that can be performed only if
the gross weight is displayed, stable, and close to the basic zero. Basic zero setting of
the gross weight must be performed in the calibration sequences.
Levels: This function gives the possibility to rapidly view and edit the switch-over value
for the Levels, assigned to the scale.
Function Levels can be used only if at least one of the 32 Levels is assigned for
the scale in sub menu Param. Set-up / Level Superv.
Pre.Tare: This function opens menu Preset Tare for the scale, where the value of
preset tare can be viewed and edited.
Preset Tare can be opened only for scales that have Tare Corr.Mode set to
Preset or Auto+Preset in the scale calibration.
W/F: This function performs toggling between display of the weight value and
and the calculated flow value. Flow display can be selected only if program option
'Flow rate' is activated and Flow Calc. is set to On in the scale calibration.

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 letter ‘Z’ is shown
under the measurement value.
Minor correction of the zero value may be needed and can rapidly be performed.
Zero adjustment
If, for unloaded scale, the letter ‘Z’ is not shown, but the gross weight is close to zero, a
rapid zero adjustment can be performed.
The gross weight must be stable (letter ‘M’ not shown)
and the zeroing function must be enabled.
Press key ↑.
Additional functions for the scale will appear
to the right on the bottom line.
Use key + or – to scroll to the Additional function
'Zero'.
Press key ↵to perform zero adjustment.
Gross weight, adjusted to zero, is displayed.
000.2 kg
S1:G Zero

Zero adjustment can only be performed if the accumulated deviation from the basic
zero setting in the last calibration is within -1 % to +3 % of the ‘Capacity’.
In other cases a new basic zero setting must be executed.
Gross weight and net weight
The gross weight is the total weight loaded on the scale after zero setting.
When gross weight is displayed the letter 'G' is shown under the measurement value.
The net weight is the difference between the gross weight and a tare value.
When net weight is displayed the letter 'N' is shown under the measurement value.
Net weight can not be displayed if the tare value is zero.
Switch-over between display of gross weight and net weight can be performed if
parameter 'Gross/Net key' is set to 'On'. This makes the additional function 'B/N'
available for the scale.

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 if parameter 'Tare key' is set to 'On'.
This makes the additional function 'Tare' available for the scale.
But the scale can also be set to allow taring only at stable weight (letter 'M' not shown).
In G4 two tare values can be stored, 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'.
Press key ↑. Additional functions for the scale will
appear to the right on the bottom line.
