5 Changing Sheaves
As you use the Quick Balance on different diameter cables you must change to the
correct sheave size. To change sheaves, remove the hex head screws pointed out in
Figure
5.1 below. Replace the sheaves with the correct letter sheave and reinsert the
screws and tighten.
Insure sheaves installed agree with sheaves noted in the Wire calibration. Exception:
Sheaves match the wire diameter of the cable to be measured and alternate calibration
is selected as per the instructions in Calibration to Specific Wire Type
on page 22 .
Insure that the wire rope is riding in the groove of all three sheaves.
Figure 5.1 Changing sheaves
Do not use the Quick Balance with cable larger than indicated on the sheaves.
Overload and damage to the instrument may result.
Do not mix sheave sizes. This will result in inaccurate measurement and possible
overload.
