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

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 Endpoint

"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.

Following the last procedure, "4-0" is displayed with either digit flashing. "4" indicated 4-20mA (default), and "0" indicates 0-20mA.

Continue with next SET-UP routine or hold ENTER to return to RUN mode.
