Instruction manual

3. Measure the length of the part with the most precise measuring tool

available (i.e. digital calipers).

4. Press the zero key on the ProScale digital display.

Note: If the direction of movement and the direction shown on

the digital display are opposite, the position of internal jumper JP3

should be changed. See Section 3 for more information.

5. Press and hold the PLUS key to scroll until the length measurement

is displayed (the longer the PLUS key is held down, the faster the

display will scroll).

6. When the proper reading is reached, lock the display if desired. This

prevents accidentally re-zeroing of the display. See Section 3 for

more information about how to lock the display.

7. Re-calibrate, if necessary, after changing saw blades (or applicable

tooling).

8. Calibration is not necessary after batteries are changed.

Maintenance:

The aluminum scale should be cleaned of debris often. This will prevent

premature damage to the scale or readhead. Should the readhead

assembly become difficult to move, check that the scale is thoroughly

cleaned. Find and remove any burrs which may have developed on the

aluminum scale. Do not use any liquid lubricants on the scale assembly,

as this may:

1. Impede the readhead's ability to operate properly.

2. Attract other contaminants to the scale.

The Digital Display should be cleaned periodically with compressed air to

remove any dust on the lens and keys. All mounting fasteners should

occasionally be checked for tightness. If there is any wear on the green

laminate of the scale, the guide clip pressure on the readhead should be

reduced. If wear continues, the readhead bearing should be replaced.
