4.2.4 How To Revert To Factory Default Settings

The factory set Reference Zero is re-established by changing any
(concentration measurement effecting) parameter value such as Transducer
Temperature, Carrier Gas Species, Specific Heat Ratio or Molecular Weight.
The Controller’s USER SET ZERO LED will be illuminated only if a user set
Reference Zero is being used for calculating Concentration. All other parameter
values must be altered through the digital link. Certain configuration information
is set with the placement of SW#7 and SW#8 on the CFGR2 switch block, see

section 4.3.6.6, CFGR2, on page 4-26

. Refer to

section 3.1.12 on page 3-10

for

additional methods of re-establishing factory zero.

The optional Monitor Software allows the instrument to be reset to Factory Zero
directly from the Calibration menu.

The optional LCD display controller may be reset to the default parameters by
holding the C key down through two power "on" cycles.

The factory default settings are shown in
