Reinstall Platform
1.
Clear all debris from the scale area. Make sure that all four load pin receivers in the
frame are clean and free of all foreign material.
2.
Replace the platform into the frame. Make sure there is slack in the cable between
the frame and platform and that no cable pinching occurs.
3.
Move the platform back and forth in both directions to make sure that the rocker
pins are seated in the receivers and there is no binding.
4.
Calibrate the scale according to the METTLER TOLEDO indicator manual.
Note: For 2 mV/V load cells,
jumpers W1, W2, W3, and W4
must be ON (shorting the pins).
