SELF_TEST ALGORITHM
Use the < > arrow keys again to move the blinking to APPLICATION
and press
Enter
.
Sel rng to set appl:
> Ø1 Ø2 Ø3 CAL <
Use the ∆∇ arrow keys to increment/decrement the range number to 01,
02, 03, or CAL, and press
Enter
.
Imp: H2 Bck: N2
FR:Ø TO:1Ø %
Use the < > arrow keys to move to Imp: (impurity), Bck: (background),
FR: (from—lower end of range), TO: (to—upper end of range), and PPM or %.
Use the ∆∇ arrow keys to increment the respective parameters as desired.

Analyze
mode. (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:
If started with the RS-232, send:
st<enter>
st<enter>
to the analyzer from the computer.
If started through the front panel, turn the instrument off and back on.
Press the Enter key twice to return to the Analyze mode.
