cover is closed. This is important because the drum selects the proper transformer connection for
the required voltage.
The supplied moulded line cord should be plugged into the 3 pin power receptacle on the rear
panel of the instrument. Plug the line cord into a receptacle with the required voltage and a
protective ground connection. A ferrite sleeve (part no. 060-13229) is provided with the Spare
Parts. This sleeve should be installed over the line cord to reduce electromagnetic emissions.
Where the moulded plug on the supplied line cord does not match the power outlet receptacle the
plug may be removed and replaced with a 3-pin plug of the correct type.
The plug should be wired as follows:
Brown

Line voltage
Blue
-
Neutral
Green/Yellow -

PRECAUTIONS
The instrument should be disconnected from the line supply before any attempt is made to
remove the cover. Lethal voltages are present at several points within the instrument and under
some operating conditions at the source connector.
Therefore ONLY QUALIFIED
PERSONNEL WHO ARE AWARE OF THE NECESSARY PRECAUTIONS SHOULD
BE GIVEN ACCESS TO THIS EQUIPMENT.
Operation of the instrument with the cover removed will result in degraded performance due to
the lack of shielding from radiated electrical interference.

CONTROLS AND INDICATORS
The front panel of the 6530 TeraOhm Bridge-Meter, as shown in Figure 2-2, has a prominent
256 by 64 dot vacuum fluorescent graphic display, which provides a visual readout of data and
status. Four momentary action programmable function keys located below the display window
combine to provide complete user control and functionality of the 6530. A conventional 3
column by 5 row keypad matrix provides user entry of the digits 0,1,2,3,4,5,6,7,8,9,-, and (.). In
addition, a set of keys labelled “CLEAR”, “E”, “LOAD”, with cursor movement keys Up Arrow,
Down Arrow, Left Arrow, Right Arrow and menu control keys “PREVIOUS” and “CANCEL”,
allow for operator navigation through the set-up and operation of the 6530.
