Model 302
Six Channel USB PeakSimple Data System
The Model302maybeusedwithanybrandormodelofGCorHPLCofferingananalog detector
outputsignal ranging from -5V to +5V. Itincludes three independent, programmable controls (0Vto+5V
analogoutput) for temperature & pressure or HPLCgradientformation. The Model 302 has six channels,
whichcanbe randomlyassigned tooneoffourtime bases,which allowsindependentstart andstop timesfor
fourseparateinstruments. Fourremotestartinputscompatiblewith2-wireswitchclosures(typicallyoutputby
GCsandHPLCs asa remotestartsignal) arealso includedforyour use. Twopulsestretchers areprovided to
accommodateintstrumentswithremote startsignalsshorter thanonesecond (suchasHewlett PackardGCs).
Thecomputertowhich youconnectthe Model302must supportUSB(it musthaveat leastoneUSB
port—rev2.0orhigher—and use WindowsTM 98, 98SE, ME, 2000, XP or newer).
The Model 302 comes in a sturdy

1. Open the Model 302
VerifythattheModel302ispoweredOFFandunplugged. Removethethumbscrews
on both sides of the Model 302 box and slide the top cover up and off. It is
connected to the bottom of the box by a ground wire, so just set it next to the
bottomhalfof thebox.
TheModel 302 box contains two circuit
