Text „SA‟ will showing in the LCD denote that the current calibration result is saved 

The text „END‟ will be displayed at the end. The meter is ready for pH measurement 

The steps are same like that if the buffers are pH4.0,pH7.0 and pH10.0; 

 

Conductivity calibration 

Prepare for 1 measuring glasses with 84uS/cm conductivity buffer solution, and 1 measuring glass for water. 

STEPS 

OPRATIONS 

Insert the electrode into the distilled water or purified water for 10– 30 minutes to activate before press 

ON/OFF key to turn the meter on. 

Place the electrode into the measuring glass of water to clean, and wipe it up by tissue 

Place the electrode into the 84uS/cm conductivity buffer solution, The pH value will be updated until a 

stable reading is reached(The data maybe not accurate if the electrode is not be activated) 

press CAL key for 3 seconds

 

until the text „CAL‟ appear on the display, and release the key 

Text „SA‟ will showing in the LCD denote that the current calibration result is saved 

The text „END‟ will be displayed at the end. The meter is ready for conductivity measurement 

The steps are same like that if the buffers are 1413uS/cm

NOTE: The calibration will be failed if there is no “SA” on the screen during the operations, buffer solutions or the damage 

of the electrode should be checked. 

*Overange Reminder 

There will be 

1- - .-

on the display if the pH value is under 0 or over 14; 

There will be 

1- - .-

on the display if the conductivity value is under 0 or over 200;    (6321)

 

There will be 

1- - .-

on the display if the conductivity value is under 0 or over 2000;    (6322)

 

There will be    „L‟ or „H‟ on the temp. display area if the temperature is under 0

  or over 50

*Low Voltage Reminder 

The battery sign will be appeared on the display when battery replacement is needed. 

MAINTENANCE 

Keep the glass electrode clean, and cover with the protection cap when not use. Be aware of the damage of the electrode 
when use it. Products should be kept and stored in a cool, dry place that away from direct sunlight.
