Operation 3000ZA-3X
Teledyne Analytical Instruments 36
Track in Cal: Analog output tracking during calibration user
preference setting. The setting is remembered after power is turned off.
Select “Yes” to have analog output track during calibration (either span
or zero). Select “No” to hold analog output to last reading before
entering calibration mode. If analog output is not tracking during
calibration, it will hold the output for a minute after the end of
calibration to allow calibration gas to be purged out by sample gas.
4.3.9 Auto-Calibration Timer
This function sets the timer for auto calibration. It is useful when
control valves are available and the remote valve control outputs are used.
Note that if used, only one sensor may be calibrated. Whatever sensor is
selected from the span menu. So make sure to pre-select the sensor on
section 4.4.1
4.3.10 Change Stream
Use this function with cal valve option to switch on any valve:
Analyze, Zero or Span. This will allow the user to check the analyzer
response to cal gas without entering calibration mode.
