the plug-in power supply. The plug-in power supply supplies the pH
(340i) meter 340i with low voltage (12 V DC). This saves the batteries.

The line voltage at the operating site must lie within the input voltage
range of the original plug-in power supply (see
chapter 7 T
Warning
Use original plug-in power supplies only (see
chapter 7 T
