• 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 calibration 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 cali‑
bration by pressing the ARROW keys. The “Cust.” tag will be displayed.
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.
