NOTE
If this option is selected, all data in the averaging stacks is reset and the data 
for as much as the last 30 days will be lost. 

From this option the two detector levels may be 
displayed and a basic calibration conducted. 
While in this mode the gas cell is not moved; 
this gives an immediate response for setting up 
the detector levels. The basic calibration of the instrument is set by a 'CAL 
FACTOR' that is calculated during a calibration routine. Press the ENTER key 
while this is displayed and the following options are available: 

Both the D1 and D2 levels can be displayed; 
saturation counts are also displayed. To give an 
immediate response to any alterations that are 
required, the filters and gas cells are not moved 
during this operation. 

Refer to Section 3, Configuration and Startup and, Section 4, Diagnostic 
Mode for a discussion of these levels - detector level and saturation count. 

NOTE
The SPAN FACTOR is initially set at the factory; do not adjust it unless the 
instrument sensitivity is suspected. In any case it is recommended that before 
adjustments are made the original value is recorded. 

Instrument sensitivity can be adjusted if a 
known concentration of measurement gas 
exists between the transmitter and receiver 
units, and instrument sensitivity is suspected. If 
a problem arises with this consult Rosemount Analytical. 

The SPAN FACTOR may need adjusting if new gas cells or filters have been 
fitted. Refer to Span Adjust. 

This mode is for use with a Rosemount Analytical check cell. It verifies the 
calibration and operation of the analyzer. For details of its use refer to “Notes 
for Using a Rosemount Analytical Check Cell” on page 4-21. 

Press enter on viewing this display if the check 
cell mode is required. Use the arrow keys to 
toggle the display to YES and press enter 
again. 

The check cell mode is now selected. Note that 
the display will default back to Mode 1 if YES is 
not selected within 5 seconds.
