The instrument is switched for 115-volt operation when it leaves the factory. To convert
the instrument for 230-volt operation, slide the AC line conversion switch (shown in
Figure 13) to the 230V position. The fuses used in this product are 5 mm x 20 mm. The
fuses used are approved for both North American and European use; they do not need to
be changed when voltage is converted.
