a. Security Code
Refer to Figure 3-4 on page 3-14.
Reveal Current Security Code
From RUN mode, hold down DISPLAY
and ACK keys simultaneously.
Change Current Security Code
1. From RUN mode, press CAL and
Enter simultaneously.
2. SET, id are briefly displayed. Then
"000" is displayed with the right digit
flashing.
NOTE
If RUN and CAL are not press exactly
at the same time, "SRY", or "RUN" will
appear, and the analyzer will return to
RUN mode.
3. If the security code has been
disabled, skip to step 4. Use the
ARROW keys to enter the current
security code, then press ENTER.
4. If the correct code is entered, YES,
SET, id will be displayed briefly, the
code will flash. If the incorrect code is
entered the analyzer will return to
RUN mode.
5. Use the ARROW keys to set the new
security code (or "000" to disable),
press enter.
6. Continue with the next set-up routine,
or hold down ENTER until "run"
appears (the instrument is back in
RUN mode).
b. Current Output Range - 0-20mA or 4-
20mA
Following the last procedure, "4-0" is
displayed with either digit flashing. "4"
indicated 4-20mA (default), and "0"
indicates 0-20mA.
1. Press ACK until the desired range is
flashing, press ENTER.
2. Continue with the next SET-UP
routine, or hold ENTER key to return
instrument to RUN mode.
c. Range Endpoint Adjustments
The oxygen values corresponding to
minimum and maximum output current
must be set. Default is 0% for 0 or 4mA
and 25% for 20mA. Endpoints must be
within the range of the instrument and
must be at least 1% oxygen apart.
Set Oxygen Low Concentration End-
point
Following the last procedure, "CLo" is
displayed briefly, followed by the oxygen
concentration last stored to correspond to
minimum output current.
NOTE
If "CLo" is set to a value greater than
"CHi", "CHi" will be automatically reset
to a value 1% greater than "CLo".
Use the ARROW keys to set the low
oxygen concentration (0 to 24%), press
ENTER.
"CHi" is displayed briefly, followed by the
latest oxygen concentration stored
corresponding to maximum output
current.
Set Oxygen High Concentration End-
point
"CHi" cannot be set to a value equal to or
less than "CLo".
Use the ARROW keys to set the high
oxygen concentration (1 to 25%), press
ENTER.
Continue with next SET-UP routine or
