Setting and checking the Line Voltage

Warning: The line power cord must have an earth conductor to

avoid risk of shock. This instrument must be correctly earthed.

This instrument has been designed to work from either 100-120 Volt line supply or

200 - 240 Volt line supply.

Check that the voltage selector is set at the correct voltage before connecting the

power to the instrument.

Connecting the instrument to the wrong supply will cause internal. To change the

line voltage, remove the fuse / voltage selector housing, rotate through 180°and

replace with the required voltage setting at the bottom of the housing indicated by

the arrow, ensure that the correct fuse is fitted.

The instrument is set for 110V operation in the USA,

230V operation in the UK and Europe.

Power Line Inlet Fuse

The power line inlet fuse is located directly below the power inlet within the voltage

selector housing.

Design Notes

The 3000HR is built using precision resistors – no adjustable resistors are used

within the design of this reference.

Preset decade values can be selected using a RANGE button to step through in sequence with

the selected decade displayed via LED indicator.
