10.  CALIBRATION

10.1.  EC CALIBRATION

The 

HI981413

 provides a digital calibration at the push of a button. Calibrate the probe frequently 

for improved accuracy. Also:
• before in-line or flow cell installation
• whenever the probe is replaced
• after periodic maintenance
Always use fresh calibration solutions and perform electrode maintenance prior to calibration (see 
ELECTRODE CARE & MAINTENANCE section).

Preparation

Pour standard solution into clean beakers sufficient to cover the sensing portion of the probe (1 

1/2

"). 

If possible, use plastic beakers to minimize any EMC interferences. For accurate calibration and to 
minimize cross-contamination, use two beakers, one for rinsing the probe and one for calibration. 

1 1/2 “ 

Procedure 

• Raise and lower the probe in the standard to ensure the entire cell area is filled with standard. 
• Shake any bubbles off the two electrodes (prongs),
• Center probe in beaker away from beaker walls.

Automatic One-Point Calibration

One-point calibration can be performed using one of the standard solutions: 1.41 or 5.00 mS/cm.
• Press CAL key to enter calibration mode. “mS/cm 1.41 USE” message is displayed as the 

calibration point. The value will change to 5.00 if that standard is used.

• The controller automatically recognizes the standard value.
