Instrument power
Follow the steps below to connect the DMM6500 to line power and turn on the instrument. The
DMM6500 operates from a line voltage of 100 V to 240 V at a frequency of 50 Hz, 60 Hz, or 400 Hz.
It automatically senses line frequency. Make sure the operating voltage in your area is compatible.
The fuse is set to the expected voltage at the factory. Make sure that the correct line voltage is
displayed on the power module. See "Line voltage verification" in the Model DMM6500
Reference Manual for more information.
You must turn on the DMM6500 and allow it to warm up for at least 30 minutes to achieve rated
accuracies.
Operating the instrument on an incorrect line voltage may cause damage to the instrument,
possibly voiding the warranty.
The power cord supplied with the DMM6500 contains a separate protective earth (safety
ground) wire for use with grounded outlets. When proper connections are made, the
instrument chassis is connected to power-line ground through the ground wire in the power
cord. In the event of a failure, not using a properly grounded protective earth and grounded
outlet may result in personal injury or death due to electric shock.
Do not replace detachable mains supply cords with inadequately rated cords. Failure to use
properly rated cords may result in personal injury or death due to electric shock.
Before installing the instrument, disconnect all external power from the equipment and
disconnect the line cord. Failure to disconnect all power may expose you to hazardous
voltages, which, if contacted, could cause personal injury or death.
Connect the power cord
When you connect the power cord, the instrument may power on, depending on the state of the
front-panel POWER switch.
To connect the power cord:
1. Connect the female end of the supplied power cord to the AC receptacle on the rear panel.
2. Connect the male end of the power cord to a grounded AC outlet.
