Polar 76em calibration

[Dan Voigt]

Trying to calibrate a polar 76em. Its reading 30 inches but is at 4 inches. Any help to get it to recalibrate correctly?

If nobody has altered settings on tam card, then tam card or linear rule is faulty, or reference micro switch is faulty

I will check error 29 when back in office

I think error 29 means some key is pressed or active while machine switching on. Check all keys on keyboard or any micro switch

Hi sir

Please review this;

1) Check connections and cable between
length measuring system arid CU'unit.

2)LEDV3 in TAM must be flashwhen backgauge travels within the
middle third of travel lenght.

3) Exchange cpl. length measuring


4) Exchange card TAM or AR
