1.2

connecting the 5492B multimeter to a power line, please check that the correct fuse is

in place, and the fuse box inside the fuse holder is adjusted correctly. See section

for

details.

Follow the procedure below to connect the 5492B to line power and turn on the instrument.

1. Check the line voltage and be sure it is within the acceptable range of the meter BEFORE

2. Check the fuse box position inside the fuse holder to make sure it is in the correct position that

corresponds to the line voltage the unit will be connected to. The fuse holder will have a selected

voltage label on the front to indicate the selected voltage tab for operation. Change the fuse box

position to change between 110 and 220. If you’re not sure, see section

connecting into the AC input in the rear panel of the instrument. Applying an incorrect voltage

may cause damage to the instrument and void its warranty.

1.2 for details.

3. Check that the correct line fuse is properly inserted into the fuse box. The fuse rating between

110V and 220V operation is different. Refer to section 1.2 for details.

4. Before plugging in the power cord, make sure that the front panel power switch is in the off (out)

position.

5. Connect the female end of the supplied power cord to the AC input on the rear panel. Connect the

other end of the power cord to a grounded AC outlet.

WARNING: The power cord supplied with the Model 5492B contains a separate ground wire for

use with grounded outlets. When proper connections are made, instrument chassis

is connected to power line ground through the ground wire in the power cord. Failure

to use a grounded outlet may result in personal injury or death due to electric shock.

6. Turn on the instrument by pressing the front panel power switch.

2.6.2 Power-up Sequence

On power-up, the multimeter performs self-tests on its EPROM and RAM and lights all segments and

annunciators for about 1 second. If a failure is detected, the instrument momentarily displays an error

message and the ERR annunciator will turn on.

If the instrument passes self-tests, the firmware version and the model number will display momentarily

before it is ready for use.
