keys; then press to continue.
The zero point of the combination electrode determined by the device and its
slope in the acidic and alkaline ranges of the characteristic curve are also
displayed.
✱
Use the key to accept the calibrated values or
reject them with the key.
The device returns to measuring mode.
8.6 pH Antimony measurement chains, ISFET pH
combination electrodes
Antimony measurement chains and ISFET pH combination electrodes are
calibrated similarly to "normal" pH measurement chains.
