Span Calibration [
SCALE]:
Uses two weight values: Zero and at or near the full
capacity of the scale. Span calibration should be
performed if the scale is repositioned or when the room
temperature changes.
Linearity Calibration [
line]: Uses three weight values: Zero, 50% of capacity and
full capacity. Generally this calibration is not required
unless testing shows that the linearity error exceeds the
linearity tolerance in the specification table. Accuracy of
weights is important to maintain weighing integrity.
Backlight [
-F1-]: -F1- Backlight on when displayed value is > ±10d
-F2- Backlight always on
-F3- Backlight always off
Auto-Off [
oFF]:
Will automatically turn the scale off if no activity is
detected. Set between 60-540 seconds.

TABLE 5-1. TROUBLESHOOTING.
Symptom Possible Cause Remedy
Cannot turn on • No power to scale
• Empty or incorrectly installed batteries • Verify AC adapter connections and voltage
• Replace batteries, check polarity
Poor accuracy • Improper calibration
• Unstable environment
• Debris touching the pan
• Draftshield is touching the pan or
sample
• Perform calibration
• Move scale to suitable location
• Clean any debris next to or under the pan
• Check that pan is fully seated, check sample height
Cannot calibrate
• Unstable environment
• Incorrect calibration mass • Move the scale to a suitable location
• Use correct calibration masses
Err 0 • Under-load condition • Verify pan is installed
Err 1 • Over-load condition • Verify excess load is removed from pan
