Display Test
The Display Test screen displays
all dots “on” when first accessed. After three seconds, all dots turn “off”. This
cycle will continue until the LEFT navigation key is pressed to return to the menu.
Keyboard Test
The Keyboard Test screen enables testing of the indicator keys, including Scale function keys, Navigation keys and
Numeric keys.
Press any key and the screen will display a graphic for that key. When testing is complete, press the
LEFT
navigation key to return to the menu.
Scale
Scale diagnostics setup screens include Load Cell Output, Calibration Values and Statistics.
Load Cell Output
The Load Cell Output screen displays the current number of counts (active value) for the scale. These are raw
counts and do not take into consideration the zero or span factors.
Press the
LEFT navigation key to return to the menu.
Calibration Values
The Calibration Values screen displays the current calibration values for the scale. The number of test loads that
display calibration values is determined by the Linearity Adjustment setting configured for the scale (see Scale >
Calibration).
These calibration values can be recorded and then manually entered into a new replacement board should a failure
ever occur, which eliminates having to recalibrate the scale with test weights. While this method is quick, it is not as
accurate as placing test weights on the scale.
