PWarning
To avoid shock hazard when powering the instrument
with ac power, connect the power cord to a receptacle
with an earth ground.
AC Power 2-6.
Plug the line cord into the connector on the rear of the instrument as shown in
Figure 2-2. The instrument operates on any line voltage between 107 and 264V ac
(45 to 65 Hz) without adjustment. Fluke warrants the instrument to meet
specifications only at 50 Hz and 60 Hz operation. Power consumption is a
nominal 15 watts. Be sure the line cord ground terminal connects to an earth
ground.
PWarning
To avoid shock hazard when powering the instrument
with dc power, connect the instrument ground terminal to
an earth ground.
