Jumper
Please note:
Each time a new sensor is connected, you must perform
an ISFET zero adjustment to adjust the operating point.
After that, you should perform one of the following calibration methods:
• Calimatic: automatic calibration
• Manual entry of buffer values
• Data entry: premeasured electrodes
