When turning off, hold the ZERO/ON Button down until the tool shuts down. Select INCH or METRIC modes by pressing the UNIT Button. Use the ABS/SET button to set a specific measurement. The RAN button will measure the minimum range of the bore being measured. The TOL button will yield the tolerance range of the bore being measured. calibration using a Micrometer, and Measuring a Bore: Set the outside micrometer (not included) to the exact dimension to be measured. Tighten the Lock Nut located on the micrometer. Place the Electronic Bore Gauge measuring contacts across the micrometer (not included). (see Figure 3) Tap the RAN Button twice. Sweep the Electronic Bore Gauge back and forth in the micrometer (not included) to set the minimum data. (see Figure 3) Remove the Electronic Bore Gauge and note the minimum data on the display. Tap the RAN Button twice to zero the indicator. please note: Micrometer sold separately; it is not included with Electronic Bore Gauge. figure 3 SKU 94873 For technical questions, please call 1-800-444-3353.
