To set up Auto Range press SETUP-RNGE-MODE-AUTO, then press ENTR. To set the values
press SETUP-RNGE-SET. The M200AH will prompt you for LO, then HI which is the lower
and upper ranges of Auto Range. Key in the value desired, then press ENTR.

Remote Range works the same as AutoRange except that the LO/HI range decision is made via
remote status inputs on the rear panel, see Figure 2-2 for pinout. Calibration of Remote Range is
also the same as for AutoRange see Section 7.8. To select Remote AutoRange press SETUP-
RNGE-MODE-REM, then press ENTR.

5.3.4.5. Dilution Ratio
The dilution feature allows the M200AH to be used with a stack dilution probe. With the
Dilution feature you can select the range and display the concentration at the value and units of
the un-diluted gas in the stack. The dilution probe dilutes the gas by a fixed ratio so the analyzer
is actually measuring a much lower concentration than is actually present in the stack.

The software scales the diluted sample gas concentration readings so that the outputs show the
actual stack concentrations. Also, when calibrating the instrument or setting the ranges the
values selected are scaled to reflect the actual stack concentrations. The scaled readings are sent
to the display, analog outputs, and RS-232 port.

To use the Dilution feature:
1. SELECT UNITS
For stack measurement, select PPM units. To set units, press SETUP-RANGE-UNIT-PPM. Press
ENTR after the unit selection is made, then EXIT to return to upper level menus.

2. SET DILUTION RATIO
The dilution ratio of the probe is entered by SETUP-RANGE-DIL. Accepted values are 1 to
1000. Press ENTR, and EXIT to return to upper level menus. A value of 1 disables the dilution
feature.
