ISPLAY
The VFD/LCD display setup parameters define the operation of the
standard displays.
P420: Standard VF Display Mode
Selects the operation of the standard 7-segment VF display and control
the backlighting of the LCD.
If set to ON, the VFD will always remain on with the intensity set at P423.
The LCD backlight will also remain on provided the backlight is enabled at
P294.
If set to OFF, the VFD will always remain off with the intensity set at P424.
The LCD backlight will also remain off regardless of the backlight setting at
P294.
If set to AUTO, the VFD will remain on with the intensity set at P423 as
long as the scale does not become stable within the number of divisions
set at P421 for the length of time specified at P422. This condition will
also maintain the LCD backlight. Once stability is achieved within the
parameters of P421 and P422, the VFD will turn off with the intensity set at
P424. In the case of the LCD, the backlight will turn off. This serves as a
power saving feature when the indicator is being powered by battery. Use
of this feature may also extend the life of the VFD.
P421: Weight Threshold Divisions
Selects the number of divisions required to yield a stable condition for
P420.
P422: Time-out
Selects the time-out period required to yield a stable condition for P420.
P423 – P424 Display Brightness (7-segment VFD only)
Selects the degree of VFD brightness when the display is on (P423) and
off (P424).
P425: 4X20 VF / LCD Display Enable
Enables the 4X20 VF display for displaying the auto-update information
normally sent to the 7-segment VFD. This parameter is normally enabled
only for the model 661 where the 7-segment display is not present and
there is no other means of displaying the auto-update information.
When an LCD display is installed, it is auto-detected by hardware. This
will result in P425 being automatically set to LCD Always. It will not be
possible to over-ride this setting as long as the LCD is installed.
P430: LCD Contrast (LCD only)
Selects the power-up contrast setting for the LCD display. Pressing [CLR]
will restore the default contrast setting.
The LCD contrast can also be set at power-up without accessing the setup
mode. Refer to the section on LCD Contrast Adjustment on page 2-27.
