User guide

• Each time a buffer is confirmed, the new calibration data

replaces the old calibration data for the corresponding buffer.

If current buffer has no previous data stored and the cali-

bration is not full (five buffers), the current buffer is added

to the existing calibration. If the existing calibration is full,

the instrument asks which buffer to replace.

Press the ARROW keys to select another buffer to be

replaced.

Press CFM to confirm the buffer that will be replaced.

Press CAL to leave calibration without replacing.

Note: If the replaced buffer is outside the ±0.2 pH window,

around each of the calibrated buffers, it is possible to

select this buffer for next calibration during current

calibration.

WORKING WITH CUSTOM BUFFERS

If a custom buffer was set in SETUP menu, it can be selected during

calibration by pressing the ARROW keys. The “BUFFER pH” tag will

blink.

Press SETUP if you want to adjust the buffer value. The buffer value will

start blinking.

Use the ARROW keys to change the buffer value.

After 5 seconds, the buffer value is updated. Press SETUP if you want to

change it again.

Note: Custom buffer value can be adjusted in a ±1.00 pH window,

around the set value.
