For power conservation purposes, the PQ100 is equipped with an algorithm which detects
inactivity. If the front panel pushbutton switches or the RS232 port are not used within 3
minutes the unit will power itself off.
6.3 What to Do Next
Pressing the "Setup" key steps through the various Menu Selections. Each of the
selections are explained in detail, in the order they will be encountered, on the following
pages.
6.4 Setting a New Target Flow Rate
From the "MAIN IDLE DISPLAY" press the "Setup" key once until the message below
appears;
Select FLOW RATE
Target Q... xx.yLpm
where;
xx = Liters per minute
y = tenths of a Liter per minute
The target flow rate is that which the PQ100 will draw air through the inlet at when a run
is initiated.
If the displayed flow rate is acceptable and you do not wish to change it, press the "Setup"
key. This action will change nothing and will step the menu to the next selection. If a
change is required, press the "Enter" key. You will notice that the whole number value
(the value preceding the decimal point) will then remain on while the tenths value
continues to flash. The value that remains on is the one that will change when the "+/-"
keys are pressed. When the proper value has been reached, pressing the "Enter" key will
then select the tenths value (the digit after the decimal point) for editing. After the values
have been entered, pressing the "Setup" key will then store the new values in memory and
step to the next menu selection.
