Mains power (pH 340i only)
You can either operate the measuring instrument with batteries or with the
plug-in power supply. The plug-in power supply provides the measuring in-
strument with low voltage (7.5 V ... 12 V DC). This saves the batteries.
Warning
The line voltage at the operating site must lie within the input voltage range
of the original plug-in power supply (see T
ECHNICAL DATA).
Warning
Only use original plug-in power supplies (see T
ECHNICAL DATA).
