2.2.2 Selecting the Voltage
The transformer voltage selector
and the power supply voltage
selector settings must match when
the analyzer is powered on.
Incorrect settings will damage your
analyzer and void the warranty.
With the appropriate voltage selector settings, the analyzer is capable of
operating on either 115 V ac or 230 V ac, 50 to 60 Hz.
Make sure the instrument power is off before selecting or changing
voltage settings. Change the settings using the two switches that are located
inside the electrical compartment door, as shown in Figure 17. Ensure the
correct voltage label (115 or 230 V) is shown on the analyzer rating label
inside the analyzer enclosure. See Figure 17.
