This test should be used as a diagnostic tool only and can assist with the diagnosis of linear speed errors ER1 and ER2.
Procedure
1. Enter the access code
176
.
2. The display will show ‘Linear Diagnosis xxx.xx mm' (xxx.xx mm represents the current position of the plunger holder).
3. Declutch the drive mechanism and move the plunger holder to the extreme right, past an ind105.00mm.
4. Re-engage the drive mechanism carefully . Sharp jolts on the transmission at this point can affect the results.
5. Over some minutes the screen will display a graph of linear error. Note: This is percentage deviation from linear path
between left and right calibration points.
6. Check that the plotted line remains within the ±1% lines (Unmarked), and that no sharp increases or decreases in
deviation occur.
Troubleshooting
Note that sharp jolts, or incorrect linear calibration may affect the result.
If test fails:

Perform the ‘Linear Pot Calibration’, see Chapter 2

Replace the Linear travel potentiometer
