Storing and Shipping the Multimeter
The Multimeter should be stored under cover. The shipping container provides the most
suitable receptacle for storage, as it provides the necessary shock isolation for normal
handling operations.
Place the Multimeter inside a sealed bag. Place the bag into the cushioning material
inside the shipping container, and put the whole package in a location that complies with
the storage environment specification described in Chapter 5.
If the Multimeter is shipped, use the original shipping container if possible. It provides
shock isolation for normal handling operations. Any other container should provide
similar shock isolation to the following approximate internal packing dimensions (the
front terminals should be free):
Container Length Width Depth
Box 630 mm (25 in) 550 mm (22 in) 230 mm (9 in)
Cushioned 480 mm (19 in) 440 mm (17.3 in) 100 mm (4 in)
Place the instrument inside a sealed bag. Fit the bag into the cushioning material inside
the shipping container, and secure the whole package.
Line Voltage
Power Voltage Selector and Fuses
The instrument is packed ready for use with a line voltage determined at the time of
ordering.
8508A 115 or 8508A/01 115 For 100V to 120V supplies
8508A 240 or 8508A/01 240
For 200V to 240V supplies
Changing Supply Voltage or Replacing Line Fuse
The integrated POWER SWITCH, POWER INPUT plug contain the fuse drawer which
gives access to the line fuse and the line voltage selector.
Insert a small screwdriver blade in the narrow recess above the catch over the fuse drawer
to gain access to the fuse and the voltage selector.
To change from one voltage to the other, remove the voltage selector block and rotate
until the desired voltage faces outward. Refit the selector block and fit the corresponding
fuse. Check that the desired voltage is visible in the cutout of the fuse drawer.
For 200 V to 240 V supplies 230 is shown in the voltage selector window on the rear
panel.
For 100 V to 120 V supplies 115 is shown in the window.
Refer to Table 1-3 for full details of replacement Power Input fuse types.
