Using the AC/DC Power Supply
The optional AC/DC power supply (800122) can be used to power the
instrument. Be sure to provide the correct voltage and frequency,
which is marked on the back of the AC/DC power supply.

to supply power. Use of an incorrect power supply can cause the
measurements to be inaccurate.
