Warning
The Model 185/186 operates on 50-60 Hz power and may be
configured for 110-120 or 208-240 VAC ±10% (100 or 200 VAC ±10%
for Japan and South Korea). The power requirements for each
instrument is marked on the calibration sticker on the bottom of the
instrument. Be sure your instrument is configured for 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.
Ensure the front panel switch is in the OFF position. Verify that the
instrument is configured for the proper operating voltage by referring to
the calibration sticker affixed to the bottom of the instrument. If the
operating voltage is correct, plug the line cord into the appropriate power
receptacle.
Warning
Do not install the instrument in a manner that prevents removal of
the line cord from the rear panel of the instrument.
