How to Set the Resistivity Setpoint (C02)
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 How to Understand
Direct-Q R messages
). The factory default resistivity value is set to15 M
Ω
. cm @25
°
C.
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
Ω
.cm @25
°
C
to 18.0 M
Ω
.cm @25
°
C.
If Conductivity Units are chosen in C01,
then the Setpoint can be adjusted from
0.999
µ S/cm @25 ° C to 0.055 µ S/cm
@25
°
C.
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 µ S/cm @25 ° C.
