To use this mode, Press the "Run/Stop" key to turn on the pump (pump will start to draw

at somewhere in the range of the target flowrate depending on the resistance presented by

the filter and calibrating device) and the following message will appear;

Reference Q.. rr.r

Where;

rr.r is an approximate flow rate used only as a visual aid in finding the

corrected flow on the calibration device. This value may indicate 5

to 15% error. Don't be concerned! This is for reference only!

Use the "+/-" keys to move the pump speed up or down until the calibration device

indicates the "Corrected Flow Rate" value as determined by the Calibration Equations

given on the following pages.

HOLDING DOWN THE "RESET" KEY WHILE PRESSING THE "+" OR "-" KEY

WILL ALLOW FOR COARSE ADJUSTMENT OF THE PUMP SPEED. WHEN THE

PUMP SPEED WILL SEEM TO GO NO HIGHER OR LOWER, THE UPPER AND

LOWER LIMITS HAVE BEEN REACHED.

When a good stable reading has been achieved, pressing the "Enter" key will store both

the "Actual Sensed Flow Rate" and the pump speed data into the table of non- volatile

calibrations where they will remain as "Constants" until a change is required (Only under

"Extreme Ambient Conditions" as it should be impervious to moderate changes) and will

then exit the Setup menu and return to the "MAIN IDLE DISPLAY".

CALIBRATIONS ARE NOT AFFECTED UNTIL THE ENTER KEY IS PRESSED

AND THE PUMP IS RUNNING.

7.2 Using a DeltaCal or TetraCal (formally triCal)

The use of a DeltaCal or TetraCal (formally triCal) is highly recommended for calibration

of the PQ100. Connect either unit to the PQ100 just before the filter holder and read the

actual flow on the display. More information on the DeltaCal or TetraCal (formally

triCal) may be found at www.bgiusa.com/cal/index.htm
