To standardize the meter with Manual Buffer Recognition

1. Touch std on the pH measure screen to access the standardize

screen

2. Touch clear to delete a previous standardization. All pH

standardization values will be cleared. The meter will remain on

the standardization screen at this point.

If the screen says “Not Standardization” proceed to step 3.

3. Immerse your rinsed electrode(s) in a buffer solution and stir

gently.

4. Touch std again to standardize the meter using this buffer

5. Using the displayed keypad input the value of the buffer that you

are using to standardize the meter and then touch enter. The

meter will accept the value once it recognises that the reading is

stable. At that time, STABLE will appear on the screen. A beaker

icon and the entered pH value will also appear on the screen at

this time. The meter will then return to the pH measure screen.

6. Touch std on the pH measure screen to access the

standardization screen and repeat steps 3 through 5 to

standardize with up to 5 buffers.

Updating a standardization with manual buffer recognition

You can update a standardization at any time. To update a

standardization with manual buffer recognition, place your electrode

in any of the buffers originally used to standardize the meter and

touch the std key on the touch screen twice. Then using the keypad

displayed on the screen, enter the value of the buffer and touch

enter. The value for that buffer will be updated and stored in the

meter’s memory. The time of standardization will also be updated and

stored in the meter’s memory. The time of standardization will also be

updated on the pH measure screen.
