Logged Data File – Menu Page 13

Each minute, there are 15 points of data collected.  The time of each data point is shown along the left-hand side of the screen.  The arrow buttons will scroll backwards and forwards in time, however it will not allow you to view data beyond the current time.  Although 15 data points are stored, only 5 are visible at one time.  The others can be accessed by pressing the circular arrow key at the bottom right of the keypad.  When the screen is first accessed, the following five variables are shown:

 

(00)    IR%C – Percent Carbon as computed by the PGA3500

(01)    IRTC – Temperature used by the PGA3500 to compute the Percent Carbon

(02)    %CO – Percent Carbon Monoxide

(03)    %CO2 – Percent Carbon Dioxide

(04)    %CH4 – Percent Methane / Natural Gas

 

Pressing the circular arrow button will display the following five variables:

 

PB%C – Percent Carbon as computed by the probe

PBTC – Probe Thermocouple (Temperature)

PBMV – Probe Millivolts

PBCF – Probe CO Factor

PBPF – Probe Process Factor

 

By pressing the circular arrow button again, the following screen is shown:

 

The abbreviated headings for the columns represent:

 

%O2 – Percent Oxygen

FLOW – Flow Rate (0 to 100 represents 0.0 to 2.0 SCFH)

ShmF – Infrared Shim Factor Adjustment Setting

CH4F – Infrared CH4 Factor Adjustment Setting

IRkP – Sample Pressure in KiloPascals

 

Pressing the circular arrow button again will return you to the first set of variables.
