5.5. Programming Mode – Non-intrusive Operation
5.5.1. Introduction
Non-intrusive calibration and programming is accomplished using a magnetic
wand that comes with the
unit. Placing the magnetic wand over the
embedded reed switches located under the CH1 and CH2 designations (see
Figure 5-4) of the faceplate will allow you to scroll through menus and enter the
desired function. The functions available through non-intrusive operation are as
follows.
Sensor Type
Zero
Calibration
Span Gas Value
Span Reserve (in this order).
NOTE:
Please see the end of this chapter and Chapter 8 for a complete list of
functions and function codes.
NOTE:
Typical zero and calibration times for BBIR sensors is 3 minutes. After a
calibration, the span reserve for the BBIR sensor is not available to the end user.
5.5.2. Sensor Type
To enter non-intrusive operation
during the Normal Operating Mode,
