Connecting the
plug-in
power supply
(3400i)
You can either operate the measuring instrument with batteries or with the
plug-in power supply. The plug-in power supply supplies the pH meter 3400i
with low voltage (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
chapter 7 T
ECHNICAL DATA
).
Warning
Use original plug-in power supplies only (see
chapter 7 T
ECHNICAL DATA
).
Note
You can also measure without the plug-in power supply.
1 Plug the jack (1) into the socket (2) of the measuring instrument.
2 Connect the original WTW plug-in power supply (3) to an easily ac-
cessible mains socket.
