Event Out
Four outputs,
Out 1
to
Out 4
, are provided to allow various peripherals to be
connected to the instrument. Switches S1 to S4 allow each output to be set to be
either a contact closure (upper position) or a voltage output (lower position).
Out 1
and
Out 2
, when set to voltage output, each have an output of 5 volts. The
voltage output of both Out 3 and Out 4 is 24 volts.
During a sample run Out 1 closes between acquisitions, and is used typically to
enable an external device to inject the next sample. The three remaining outputs are
reserved for future developments.
Contact Closure In
In 1 and In 2 inputs are provided to allow external device to start sample acquisition
once the device has performed its function (typically sample injection).
Analog Channels
Four analog channel inputs are available, for acquiring simultaneous data such as a
UV detector output. The input differential voltage must not exceed one volt, though
full scale automatically adjusts from 1mV to 1V.
