(The number after "t" indicates which titration point you are
on. The number "1" here indicates this is the first titration point.
Subsequent titration points are sequenced numerically: 2, 3, 4,
etc.).
12. “HOLd” displays. Keep holding the meter steady until “Add”
alternating with “A1” displays. Open the cell extender cap
carefully to avoid spilling, and use the pipette to add 100µL of
Reagent A1. Close the cell extender cap securely. Press CAL to
continue.
13.
Repeat Steps 11 and 12 until the meter reports the alkalinity
result.
14.
Press CAL. The “CAL” icon will display.
15.
Adjust the displayed value to "100" using the UP or DOWN key.
NOTE: If you scroll beyond ±10% of the reading "FAC" will display. If
you press the CAL key while "FAC" is displayed, the instrument will
return Alkalinity to factory calibration (erasing any previous wet calibra-
tion adjustments).
16.
Press CAL to accept. The unit will automatically power off.

Hardness Calibration
Prepare the materials required for titration: Hardness Standard Solution
200PPM, Reagent: HB, Reagent: H4, or Reagent: H5, cell extender,
T-plunger, 100µL pipette with a clean tip installed, and one extra clean
tip.
NOTE: If you do not complete each titration point within the 3-minute
timeout period, the unit exits the Hardness function. Start the titration
process over.
1.
Ensure pH protective cap is secure to avoid contamination.
2.
Install the cell extender by pushing the base of the cell extender
into the conductivity cell until it is fully seated.
3.
Rinse the conductivity cell cup and cell extender 3 times with
Hardness Standard 200PPM.
4.
Refill cell cup and cell extender with Hardness Standard 200PPM.
5.
Insert T-plunger into open cell extender until the “T” rests flush
on the lip of the cell extender. This will cause fluid beyond what
is required for titration to overflow the cell extender.
