The Resistivity Setpoint is used to inform you when the Product resistivity is low. When the resistivity is
below the setpoint, the Resistivity display will flash and the red Pack Alarm will be blinking (see
Section
5-7 How to Understand Direct-Q Messages ). The factory default resistivity value is set
to15 M

1. Press the Main and
“+“ Buttons
together to enter the
menu. The Display
will show C01.
2. Press the Main
Button once. The
Display will show
C02 and the
Resistivity Setpoint
value.
3. Press the “+” or “-“
Button to adjust the
Resistivity Setpoint
from
1.0 M

If Conductivity Units are chosen in C01, then the Setpoint can be adjusted from 0.999

C to
0.055
μ

NOTE: The Conductivity Setpoint display needs to be multiplied by 0.001 to get the real value. For
example, if the Display reads “055”
μ
S/cm @25
°
C, then you would multiply 055 x 0.001 = 0.055.
Thus, the real Conductivity Setpoint reading is 0.055
