4-16: Part I Teledyne Analytical Instruments
Use the
∆∇ arrow keys to enter the upper value of the range (all ranges
begin at 0 %). Repeat for each range you want to set. Press Enter to accept
the values and return to Analyze mode. (See note below.)
Note: The ranges must be increasing from low to high, for example,
if range 1 is set for 0–10 % and range 2 is set for 0–100 %,
range 3 cannot be set for 0–50 % since it is lower than range 2.
4.6.2 Fixed Range Analysis
The autoranging mode of the instrument can be overridden, forcing the
analyzer DC outputs to stay in a single predetermined range.
To switch from autoranging to fixed range analysis, enter the range
function by pressing the Range button on the front panel.
Use the < > arrow keys to move the blinking over AUTO.
Use the
∆∇ arrow keys to switch from AUTO to FX/LO, FX/MED, or
FX/HI to set the instrument on the desired fixed range (low, medium, or
high).

Press Escape to re-enter the Analyze mode using the fixed range.
NOTE:When performing analysis on a fixed range, if the oxygen
concentration rises above the upper limit (or default value) as
established by the operator for that particular range, the
output saturates at 1 V dc (or 20 mA). However, the digital
readout and the RS-232 output continue to read the true value
of the oxygen concentration regardless of the analog output
range.
