2.2 Connecting the Power Cord
To avoid electrical accidents and to maintain the safety specifications of this
instrument, connect the power cord provided only to a 3-contact (two-conduc-
tor + ground) outlet.
To avoid damaging the power cord, grasp the plug, not the cord, when unplug-
ging it from the power outlet.
To suppress noise, the instrument needs to be set to match the line frequency.
Before operating, set the instrument to the frequency of your commercial
power. If the supply frequency is not set properly, measurements will be unsta-
ble.
See "2.5 Selecting the Line Frequency" (p.24).
Make sure the power is turned off before connecting or disconnecting the
power cord.
