1U-8869 Dial Indicator
The digital dial indicator needs to be programmed to read actual timing dimensions. Since the 9U-5138 Setting Gauge in the timing and fuel setting tool group is 87.00 mm, set the digital dial indicator for 87.00 mm. Use the following steps in order to program the indicator to read 87.00 mm.
Turn the indicator to the ON position by pushing the "on/off" button.
Push the "in/mm" button so the display shows "mm".
A negative "-" sign should be in the display window under "REV". If that space is blank, push the "+/−" button so the display shows a negative "-" sign. When this is done, the movement of the plunger into the indicator will be displayed. The display will be shown as a negative movement. The movement of the plunger out of the indicator will be displayed as a positive movement.
Push the preset button and hold the preset button down until there is a flashing "P" in the upper right corner of the display. Then release the button.
Push the preset button and hold the preset button down until the flashing "P" disappears and a flashing indicator bar is seen in the lower left corner of the display. Then release the button. Use the preset button so that this position is blank.
Push the preset button and hold the preset button down until the flashing indicator begins flashing under the first number position. The first number position is located in the fourth position to the left of the decimal. Then release the button. Momentarily pushing the preset will cause the display number in that position to change. Use the preset until this position reads zero (0).
Use the preset button to move the flashing indicator and change the display numbers until the display shows 0087.00 mm. Push the preset button and hold the preset button until the flashing "P" is shown in the upper right corner of the display. Release the preset button. Momentarily push the preset button so the flashing "P" and the zeroes to the left of 87.00 mm disappear.
The indicator can now be turned off. The indicator will retain the preset number in memory. To recall the preset number, repeat Steps 1.a through 1.d.
Install a 5P-4160 Indicator Contact Point in the indicator stem.
Install the indicator into the 9U-5233 Magnetic Fixture Group. Leave the collet loose.
