7.2.3.6. Flow Calibration (Optional Electronic Flowmeter only)

The flow calibration allows the instrument to calibrate its internal flowmeter

reading. This should be done with a calibrated flowmeter connected to the "Sample

In" port of the 465L.

Figure 7-5 below shows the Flow Cal menu. After the instrument has stabilized on

the source of span gas, navigate to the Flow Cal menu (See Figure 7-2) and Press

ENT. Next enter the Flow Cal target (the actual flow as measured at the sample

inlet) and press ENT. The display will next show a confirmation menu, ENT TO

CAL. Press ENT to perform the Flow Calibration, or CFG to abort back to the

start. If the calibration is successful, the display will return to the concentration. If

the calibration cannot be performed, an OUT OF RANGE error will be displayed.

Press ENT to confirm and the display will return to the start of the Flow Cal menu.

If the OUT OF RANGE error occurs, it means the Flow Cal cannot be performed

because it would result in an out of range flow slope value for the monitor. This

means that either the flow sensor in the monitor is malfunctioning, causing improper

readings, or the actual flow is different than the target value being entered.
