Use the UP/DOWN switch to increment/decrement the range number to 01, 02, 03, or CAL, and Enter.

Use the UP/DOWN switch to increment the respective parameters as desired, and Enter to move to the next. On the last field %/ppm Enter to accept the values and return to range selection menu. (See note below.) Repeat for each range you want to set.

Note: The ranges must be increasing from low to high, for example, if Range 1 is set to 0–10 % and Range 2 is set to 0–100 %, then Range 3 cannot be set to 0–50 % since that makes Range 3 lower than Range 2.

Ranges, alarms, and spans are always set in either percent or ppm units, as selected by the operator, even though all concentration-data outputs change from ppm to percent when the concentration is above 9999 ppm.

Note: When performing analysis on a fixed range, if the concentra- tion rises above the upper limit 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 regardless of the analog output range.

To end the session, send:

to the analyzer from the computer.

3.8.2 The Curve Algorithm Screen

The Curve Algorithm is a linearization method. It provides from 1 to 9

intermediate points between the ZERO and SPAN values, which can be normal- izedduringcalibration,toensureastraight-lineinput/outputtransferfunction throughtheanalyzer.

To linearize the ranges, you must first perform the four steps indicated at the beginning of section 3.8 Programming. You will then be in the second System menu screen.
