Sri 302 Manual

The Model 302 may be used with any brand or model of GC or HPLC offering an analog detector
output signal ranging from -5V to +5V. It includes three independent, programmable controls (0V to +5V
analog output) for temperature & pressure or HPLC gradient formation. The Model 302 has six channels,
which can be randomly assigned to one of four time bases, which allows independent start and stop times for
four separate instruments. Four remote start inputs compatible with 2-wire switch closures (typically output by
GCs and HPLCs as a remote start signal) are also included for your use. Two pulse stretchers are provided to
accommodate intstruments with remote start signals shorter than one second (such as Hewlett Packard GCs).
