A single electrode efficiency will also be displayed after a two point 
calibration. This is the efficiency between the two calibration points.
Two separate efficiencies will be displayed after a three point 
calibration, one for the slope between 4.01/4.00 and 7.00/6.86 and 
another for the slope between 7.00/6.86 and 10.01/9.18.

It is recommended to clean and/or replace the electrode when the 
efficiency value is less than 90%. 

pH MEASUREMENTS

The buffer(s)

 

on the display represent the buffers used during the most 

recent calibration. The selected buffer set must not be flashing before 
taking measurements. If it is flashing, a calibration must be performed.

MEASUREMENTS IN THE pH AUTOLOCK MODE

1.  Press the 

Mode

 key until the “pH” icon and “AUTO” icon light up.

•  The “ATC” icon will light up if a temperature sensor is 

connected.

•  The “MAN” icon will light up if no temperature sensor is 

connected. The temperature can manually be set by pressing 
the 

up

 and 

down

 arrow keys. 

2.  Rinse the pH and temperature (if applicable) sensors with distilled 

water and immerse in the sample to be measured. Remove any air 
bubbles trapped around the electrode by shaking or stirring the 
electrode.

3.  Press the 

Meas. / Effic.

 key. The “WAIT” icon will start flashing. The 

unit is waiting for a stable pH and temperature measurement. 

4.  When the “WAIT” icon disappears and the “LOCK” icon appears, 

the reading is frozen and will not respond to further changes. The 
pH value shown is the pH value of the sample at the displayed 
sample temperature.

•  For samples that are inherently unstable, the unit will not 

AUTOLOCK. In this case, use the pH NON- AUTOLOCK mode 

for measurements.

MEASUREMENTS IN THE pH NON-AUTOLOCK MODE

1.  Press the 

Mode

 key until the “pH” icon lights up. 

The “AUTO” icon 

will not be on the display when in the NON-AUTOLOCK mode.

•  The “ATC” icon will light up if a temperature sensor is 

connected.

•  The “MAN” icon will light up if no temperature sensor is 

connected. The temperature can manually be set by pressing 
the 

up

 and 

down

 arrow keys.
