Cleaning 
XW Warning 
To avoid electric shock or damage to the Meter, never get water 
inside the Meter. 
W Caution 
To avoid damaging the Meter’s housing, do not apply solvents 
to the Meter. 
If the Meter requires cleaning, wipe it down with a cloth lightly dampened with water or 
a mild detergent. Do not use aromatic hydrocarbons, chlorinated solvents, or methanol-
based fluids to wipe down the Meter. 
Storing and Shipping the Meter 
To prepare the Meter for storage or shipping, place it inside a sealed bag, fit the bag into 
the packing material inside the original shipping container, and then secure the package. 
Use the original shipping container if possible, as it provides shock isolation for normal 
handling operations. If the original shipping container is not available, use a box that is 
17.5 x 15.5 x 8.0 inches, with cushioning material that fills the space between the Meter 
and the sides of the box. 
To store the Meter, place the box under cover in a location that complies with the storage 
environment specifications described in the “General Specifications” section in 
Chapter 1.  
Power Considerations 
XW Warning 
To avoid electric shock, connect the Meter’s power cord to a 
power receptacle with earth ground. 
The Meter operates on varying power distribution standards found throughout the world 
and must be set up to operate on the line voltage that will power it. The Meter is packed 
ready for use with a line voltage determined at the time of ordering. If the selected line 
voltage does not match the power that the Meter will be plugged into, the line-voltage 
setting of the Meter must be changed and replacement of the line fuse may be required. 
Selecting the Line Voltage 
The Meter operates on four different input line voltages. The selected line-voltage setting 
is visible through the window in the line-fuse holder on the rear panel of the Meter.  
1.  Unplug the power cord. 
2.  Insert a small screwdriver blade into the narrow recess to the left of the fuse 
holder and pry it to the right until the holder pops out. See Figure 2-1. 
3.  Remove the voltage-selector block from the fuse holder. 
4.  Rotate the selector block until the desired voltage rating faces outward. 
5.  Replace the selector block back into the fuse holder. 
6.  Install the fuse holder back into the Meter and reconnect the power cord. 
Changing the line-voltage setting may require a different line-power fuse for proper 
operation.
