Dear Valued Customer: conventional fuse your Model 301-DIV been replaced with self-resetting fuse. This "fuse" actually (positive thermal coefficient) device, which significantly increases resistance when current 301-DIV reaches unsafe level. This change made better protect your 301-DIV eliminate need send 301-DIV back manufacturer fuse accidentally blown. device either shut down your equipment increased resistance point where affects unit performance, simply turn equipment allow device cool about seconds. 301-DIV then turned back Please note that most common which current increased unsafe level improperly biasing detector diode. there doubt correct bias your particular detector, please contact Instruments technical support (410)342-2626 (800)891-2709.

MODEL 301DIV
SIGNAL CONDITIONING AMPLIFIER
Model 301DIV amplifier module member UDT's growing family conditioning amplifiers. interfaces positionsensing photodetectors with indicators controls supplied user. This versatile system used with bi-cells quadrant detectors nulling centering operations, with lateral-effect detectors continuous position measurement. also used normalize differential output discrete-element detectors. Model 301DIV provides transimpedance amplifiers condition detector signals, well differential amplifiers necessary generate position-related analog output. modules required when monitoring both axes quadrant lateral-effect detectors. With dual-axis systems, Model 1000 electronic collimator available measuring very small changes angular displacement. addition measuring differential output determine position, system also divides summed output order cancel effects variations incident light intensity during measurement. amplifier module's selectable input ranges accommodate detector signals ranging from indicators help users select proper range setting. Output
signals normalized maximum, user adjustable. standard Model 301DIV frequency range kHz. version also available high-speed applications. COMPLETE DETECTOR/ CABLE ASSEMBLIES. ease installation accuracy measurement, offers detector/cable assemblies which ensure proper interconnection between photodetector amplifier pins. photodetectors selected high responsivity, noise, long-term stability, uniformity, linearity over wide dynamic range. OTHER FAMILY MEMBERS Model dual-channel amplifier that provides digital display positions. Op-Eye series multi-channel computer interfaces provide costeffective conditioning optical
sensors with popular computers. Op-Eye systems accommodate dual-axis detectors, single-axis detectors, discrete sensors, combination thereof. Systems available Apple personal computers their compatibles, computer having RS-232C IEEE-488 port, computers that have internal converter. APPLICATIONS Applications many varied. remote position-sensing sensors used centering nulling operations measurement position robotics other production equipment, alignment machine tools, measurement curvature optical surfaces, laser alignment.

301DIV OPERATING INSTRUCTIONS
Connect detector(s) accordance with detector connection instructions. Select detector polarity: Common anode UDT, series, common cathode SPOT series. Select detector bias. Caution: bias wrong polarity damage detectors. Connect 301DIV line, connect monitor instruments such digital voltmeters, oscilloscopes recorders, position outputs. Illuminate detector. Turn instrument power Check that output positive. not, check detector wiring, verify detector polarity. range switch proper sensitivity. Select highest position possible, without lighting light level LED. recommended that Schottky barrier detectors biased, maximum lifetime performance. Schottky detectors identified absence suffix their model number. Lateral-effect devices tend saturate moderate light levels. This observed scanning light spot across detector along axis. output (sum Yaxes dual-axis operation) shows broad near center detector, biasing required. Biasing also desirable when using 301DIV-30kHz. Since bias reduces detector junction capacitance, higher speed response possible from detector. necessary adjust zero range 301DIV output accommodate readout device, adjust ZERO potentiometers with smallblade screwdriver. return full output 10V, turn potentiometer fully clockwise. return ZERO potentiometer electrical zero, select resistors matched within 0.15%, connect resistor between each amplifier input common (H). Then adjust zero potentiometer position output connector. DETECTOR CONNECTION INSTRUCTIONS detector/cable assemblies employed, connect cable output connector 301DIV input. component level detectors used, carefully connect follows: PIN-LSC/5D, PIN-LSC/30D. Connect detector outputs (end points) amplifier inputs detector common (center pin) amplifier input (See Fig. PIN-LSC/4, PIN-LSC/9. Connect detector pins labeled amplifier inputs detector common input Only need connected. usual, bias recommended when using Schottky barrier devices. (See Fig. PIN-SC/4D, PIN-SC/10D, PIN-SC/25D amplifiers required dual-axis operation. Connect Xpins inputs Y-pins inputs amplifier amplifier jumper inputs inputs (Y-axis pins directly connected amplifier preferred). Also connect detector common input amplifier interconnect input both amplifiers. (See Figs. PIN-SC/50 Same connections PINSC/4D. usual, bias recommended when using Schottky barrier devices. (See Figs. PIN-SPOT/2D Connect detector outer pins inputs detector common input (See Fig. PIN-SPOT/4D, PIN-SPOT/9D amplifiers required. Connect same PIN-SC/4D, except connect detector common input amplifier (See Figs. best results, insure that amplifier inputs fully shielded. input shield ground.
