CHAPTER 1
Prologue
In which the reader is introduced to the
QiQuac and its many extraordinary talents.
The QiQuac is a handsome fellow. When he’s near water he’s calm and mellow.

1. Brass Dial / Push Button. Push,
Release, and Turn to wake the
sleeping QiQuac. Push to Begin Q
measurement. Rotate to change
settings. Press and hold >1s to go
back. Hold for >10s to reset QiQuac.
2. Ch1 Radio Antenna: for best
performance, raise both T-HRECS and
QQ antenna as high as possible.
3. Ch0 Connector: Power for the T-HRECS is
on pin 9. Short pin 4&5 to reset QiQuac.
4. Mini-USB port: Connect to USB port to
charge internal Li-Ion battery and access
the SD Card. To access the SD Card, the
QQ must rst be powered down.

(EC.T) (uS/cm) a.k.a Specic
Conductance at 25oC using nlf
compensation (EU standard 27888)
14. Ch0 (solid-Displayed)
15. Ch1 (dashed)
16. Ch2 (upstream sensor dotted)
17. 3rd U/S Probe Transit Time
(Available only on the Highlander edition
with CH2 set to 3rd U/S Probe)
18. When the internal Memory Buer (MB)
is full, a dashed line will appear to the
left of the plot. You cannot adjust the
Pre BG_ECT outside of the MB.
Notes
• Ch0 (RS232 device) is always the solid
plot, Ch1 (Radio device) is always the
dashed, and Ch2 (Radio device is always
dotted. Ch2 is either the 3rd Upstream
Probe or 3rd Downstream Probe.
• QiQuac enters the main menu when
turned on. Select calibration and
measurement default values in “Setup”.
• To shut o QQ, select Power Down
from the main menu or Push and Hold
the dial for >10s.
• To practice a measurement, or
reprocess the last measurement,
select Replay from the main menu.
• To change Mass, push button and
select Adjust Mass.

CHAPTER 1: OVERVIEW
CHAPTER 2
Theory
In which the Theory by which the QiQuac
makes a Salt Dilution flow measurement
is explained to the reader.
“It’s all Relative!” the QiQuac summarized; but the T-HRECS didn’t
understand as their brains are pea-sized.
