receptacle. Failure to do this could expose the user to high voltages
and could result in life-threatening electrical shock.
Caution
The Model 286 instrument operates on 50-60 Hz power and may be
configured for 100-120 or 200-240 VAC ±10%. The power
requirements for each instrument are marked on the rear panel. Be
sure the instrument’s power requirements match your power source
prior to plugging in the line cord. Do not fail to connect the input
ground terminal securely to an external earth ground.
If the instrument operating voltage range needs to be changed, ensure the
instrument is de-energized by disconnecting the power cord from the
power source. Remove the instrument cover and slide the voltage selector
switch (S1) on the main printed circuit board to the proper voltage; for 100
to 120 VAC input “115V” should be visible in the switch window and for
200 to 240 VAC input “230V” should be visible in the switch window.
Replace the instrument cover and indelibly mark the rear panel
indications to match the new configuration.
