LIGHT IMMUNITY | Pulse modulated to provide extremely high immunity to ambient light |
PULSE STRETCHER TIMER (Optional) | Provides minimum of 10 milliseconds output duration |
OFFSET/EDR®CLUTCH KNOB ADJUSTMENT | Sets initial level on Contrast Indicator in relation to mid-scale switch point of 5 – functions as sensitivity adjustment Controls Enhanced Dynamic Range circuit (EDR®) which functions to avoid glare effect |
LIGHT/DARK SWITCH | Dark position for dark mark; Light position for light mark |
INDICATORS | OUTPUT INDICATOR - Red LED illuminates when output transistors are “ON” EDR INDICATOR – Intensity of Green LED provides indication of where in the dynamic operating range the offset / EDR adjustment has been set FULLY LIT: Operating near saturation OFF: Operating near maximum sensing range CONTRAST INDICATOR – Displays returned contrasting light levels (background vs. mark) |
