• Press the key to step through the list of points. Each point is shown as Ln.ppp where n is the point
number (1 to 5), and ppp is the approximate percentage of full scale where the linearization is applied. For
example, L1.050 indicates that linearization point one is active and was entered at about 50% of full scale. Unused
linearization points are shown with a row of dashes (e.g. L2. - - -).
• Press to change the linearization point selected or press to exit without making any changes.
• After pressing , the current weight reading is displayed. Add the calibration test mass to the scale. The
closer the test mass is to the point of maximum error in linearity the more effective will be the correction. Press
to enter a corrected weight value for this point or to exit without making changes.
• Use the and keys to enter the correct value of the calibration weight being used.
• Press the key to trigger the linearization routine. The display will show L.in P to show that linearization is in
progress. When the process is complete the display will show the weight to allow the new weight reading to be
checked before returning to the menus. Press to leave the routine or to repeat the operation.
