Guide Clip Encoder/Readhead (cable not shown) Readout Hinge General Purpose Readout Digital Scale
Getting Started: Be sure to keep the parts for the rip and cross-cut retrofits separated if you have purchased both. Installation: 1. Place strips of the foam tape across the back of the digital scale. Position the digital scale so that the top of the scale is even with the top of the fence. Press in place. See figures 3, 6, and 7 for more detail. (Alternatively, the scale may be bolted in place using the 8-32 flathead screws that have been provided.) 2. Assemble one half of each readout hinge to the 1243 Cross-Cut brackets using the screws and nuts as shown in figure 2. 3. Attach the guide clip to the 1243 clip bracket using the 8-32 x 3/8 screws as shown in figure 2. Attach the second guide clip to the 1243 extension clip bracket using the 8-32 x 3/8 screws as shown in figure 6. 4. Mount the 1243 crosscut bracket under the bolt at the main stop as shown in figures 4 and 5. Insert the ¼-20 cup point set screws and tighten gently (these prevent the bracket from twisting under the bolt). Place the other 1243 Cross-cut bracket on the extension stop in the location shown in figure 5. Mark the location of the non-threaded hole. Drill and tap this hole to 10-32. Install the crosscut bracket using the 10-32 x 5/8 socket head screw. 5. Slide the encoders onto the scale such that their cables exit towards the floor. 6. Attach the clip mount bracket to the crosscut bracket using the two 8-32 x 5/8 socket head screws and washers. Place a ¼ flat washer under the screw closest to the flip stop to act as a bumper to protect the digital scale. Position the clip mount bracket so the guide clip flexes slightly when engaging the post on the encoder. Reference the sketch to the right and figures 2, 4, 7. Readhead Model 250 Scale 33.0mm (1.3") Guide Clip 21.2mm (.83") 7. Attach the extension clip mount bracket to the crosscut bracket using two 8-32 x 5/8 socket head screws and washers. Position the extension clip mount bracket so the guide clip flexes slightly when it engages the post on the encoder. Refer to the sketch above and figures 1 and 6. 8. Verify that the guide clips engage the encoders properly over the full range of stop travel. Make any necessary adjustments. 9. Attach the other half of the readout hinge to the digital readouts using the 4-40 self-tapping screws. Install the readouts onto the stops.
10. Drill and tap ¼-20 holes into both flip stops as shown in the sketch to the right. Install the nylon screws (these act as bumpers to keep the flip stops from damaging the scale extrusion). 11. Move each stop away from the blade. If the displayed value gets smaller, reverse the orientation of the encoder on the scale (so the wires exit up), OR change the reading direction parameter inside the digital readout (refer to the Operation Manual for additional information about programming). Calibration of the Digital Readouts: 1. Check that both readouts are in ABS mode (ABS will be showing in the upper left corner of the display). If either readout is in INC mode, press and hold the ABS/INC key for 3-4 seconds to change it back to ABS mode. 2. Be sure the readouts are not locked (LOCK should NOT be showing in the upper left corner). If either of the readouts are in LOCK mode: a. Press and hold the ON/OFF key. b. Momentarily press the UNITS key. c. Release the ON/OFF key. 3. Lock each stop in place. Cut a piece of scrap material at each stop and measure the cut parts with the best measuring tool available. Record the measurements. 4. Enter the measurements into the readouts, using the PLUS and MINUS keys. (NOTE: When the PLUS or MINUS key is held down, the readings will change slowly at first, and then speed up.) 5. On each readout: a. Press and hold the ON/OFF key. b. Momentarily press the UNITS key. c. Release the ON/OFF key. The keyboard is now locked. It can be unlocked by repeating this procedure. LOCK should appear in the upper left corner of the display. 6. The above calibration procedure should be repeated each time a saw blade is changed and after the batteries are changed. HINT: Record the reading before changing batteries to expedite the recalibration procedure.
Kerf compensation for repetitive cuts: The digital readout can also be programmed to automatically compensate for the blade kerf when making repetitive cuts. This is done by programming the blade kerf into the ABS/INC key. This feature is useful when one or more strips are to be cut to a desired dimension. Programming: 1. Determine the blade kerf. 2. Lock the stop in position. The ABS indicator should be displayed in the upper left corner. 3. Momentarily press the ABS/INC key. The ABS indicator will turn off, and the INC indicator will turn on. 4. Enter the blade kerf using the PLUS key. 5. Momentarily press the ABS/INC key again. The blade kerf is now programmed. 6. Press and hold the ABS/INC key for 3-4 seconds to return to the absolute distance (from the blade). Operation: 1. Load a panel into the machine and place it against the sliding stop. 2. Make a clean-up (squaring) cut if necessary. 3. Momentarily press the ABS/INC. The readout will display the kerf value. 4. Unlock the sliding stop and adjust to the desired cutoff dimension. Notice that the digital readout first counts off the kerf amount, then counts up to the cutoff dimension. Lock the stop in the desired position, and cut the panel. 5. Repeat steps 3-4 as many times as needed. 6. When complete, press the ABS/INC key for 3-4 seconds to return to the absolute distance (from the blade).

Troubleshooting: The battery clips seem loose when changing the batteries: DO NOT bend these clips. They are specially designed to compress and hold the batteries when the readout halves are screwed together. Avoid touching the clips as much as possible. The display does not change when the stop is moved: The encoder is not properly engaged by the guide clip and is not moving. Check to be sure the encoder remains properly engaged. The digital readout has been programmed with a very small linear scaling factor. Reset the scaling factor to 1.0000. The displayed measurement is off by 0.060 inches (1.524mm): There has been a very large static electricity discharge into the measuring system. Ensure the machine and its dust collection tubing is properly grounded. Recalibration is necessary. The displayed measurement is off by a value other than 0.060 inches (1.524mm): Check that all bolts and fasteners are tight. Check that the saw blade has not been changed. If it has been changed (kerf changed), recalibration may be necessary. The PLUS, MINUS, or DATUM keys have been accidentally pressed. Recalibration is needed. The encoder is not properly engaged by the guide clip and is not moving. Check to be sure the encoder remains properly engaged. The digital readout has been programmed with an obscure linear scaling factor. Reset the scaling factor to 1.0000. There have been several very large static electricity discharges into the measuring system. Ensure the machine and its dust collection tubing is properly grounded. Recalibration is necessary. ProScale resets itself while saw is running and the stop is locked: The readout has been accidentally reset. Large voltage spikes from nearby motors, inverters, or dust collection systems can cause this. Be sure that all devices are properly grounded. Also, extreme vibration may cause this. Mount the digital readout in a different location. Be sure the DATUM key or ABS/INC key have not been pressed. Recalibration may be necessary. ProScale resets itself while the saw is not running and the stop is locked: Be sure the DATUM key or ABS/INC key have not been pressed. Recalibration may be necessary. ProScale readout reads No Enc : The encoder has been removed from the scale, or its cable is damaged. The encoder is not connected to the readout. The readout displays a battery symbol: The batteries need to be changed. ProScale uses two standard AA alkaline cells. To change the batteries, unscrew the top cover (two screws) and remove old batteries. Do not mix old and new batteries. Only install alkaline batteries. Recalibrate the readout after replacing the batteries.
