 Remote Span/Zero Digital inputs allow external control
of analyzer calibration.
 Calibration Contact To notify external equipment that
instrument is being calibrated and readings are not
monitoring sample.
 Range ID Contacts Four separate, dedicated, range relay
contacts. Low, Medium, High, Cal.
 Network I/O Serial digital communications for local
network access. For future expansion. Not implemented
at this printing.
 Optional:
 Calibration Gas Ports (Auto Cal Option) Separate
fittings for zero, span and sample gas input, and internal
valves for automatically switching the gases.
Note: If you require highly accurate Auto-Cal timing, use external
Auto-Cal control where possible. The internal clock in the
Model 3000TA is accurate to 2-3 %. Accordingly, internally
scheduled calibrations can vary 2-3 % per day.
