All electronics operate from a universal switching supply, which is capable
of auto-sensing the input voltage and working over the entire operating
range.
Internal pumps and heaters all operate on 110 VAC. An optional
transformer is required if operating on the 210-250 VAC or 90-110 VAC
ranges.
An on/off switch controls all power to the Samplers, and is accessible on
the front panel.
The motherboard contains the main processor, power supplies, a sub-
processor, and serves as the communication hub for the instrument. The
motherboard receives operator inputs from the front panel mounted
function key panel and/or over I/O connections on the rear panel, and
sends commands to the other boards to control the functions of the
instrument and to collect measurement and diagnostic information. The
motherboard outputs instrument status and measurement data to the front-
panel mounted graphics display and to the rear-panel I/O. The
motherboard also contains I/O circuitry and the associated connector to
monitor external digital status lines and to output analog voltages that
represent the measurement data. Connectors located on the motherboard
include:
External connectors include:
●
RS-232/485 Communications
