6.0 OPERATION
Note: Refer to Figure 3 for switch and button locations.
Turn the unit on by moving the Power switch (8) to the On position. The unit may be operated from the internal batteries and/or the charger/power supply. The internal batteries will be trickle charged when using the AC charger/power supply. To turn the unit off, slide the Power switch (8) to the Off/Charge position. If the charger is plugged in, the batteries will charge.
The sensor emits a laser beam, which is reflected back by a target (reflective tape/paint, keyway, contrasting colors, etc). This reflected light is sensed and amplified then compared to a threshold level (sensitivity) - the lower the threshold level, the more ‘sensitive’ the sensor is. Whenever the amplified signal is above the threshold, the output goes high (positive pulse) or low (negative pulse). The user can select either a positive or a negative output pulse using the Polarity switch (5).
The gain of the input amplifier and the sensitivity can be adjusted manually or automatically. This allows the unit to be used with many types of targets at various distances and contrasting color conditions. To select the Auto mode, turn the Sensitivity Adjust knob (7) fully counterclockwise, otherwise you are in the Manual mode. Reflective tape and high contrast color applications should be able to use the Auto mode.
6.1 Auto Mode
Make sure the Sensitivity Adjust knob (7) is fully counterclockwise and the Auto/Gain LED (3) is on. Aim the laser at your target. Press and hold the Learn/Gain button (6) until the On Target LED (1) blinks regularly or is on solid (depending on the RPM of the target). Release the Learn/Gain button. The Auto/Gain LED will blink to show what gain has been selected. Refer to Table 2.
