tions are on connector J7 and labeled as follows (see Figure 3-1 for location

Select 115/230 Volt Operation

To change the selected voltage:
• Disconnect the AC line power cord from the analyzer.
• Open the top cover of the power entry module using a small-blade
screwdriver.
• Select the voltage by rotating the fuse holder so the desired voltage
aligns with the window, then snap into place.
If you later want to switch the voltage source for the analyzer, you will
also need to change the fuses in the power entry module:
•
115 VAC - Fuse Rating: 2 amp, 250 VAC - Slow Blow
•
230 VAC - Fuse Rating: 1 amp, 250 VAC - Slow Blow
The fuse sizes are 1/4" x 1 1/4". Do not use 5 x 20 mm fuses.
If the analyzer is a 230-Volt type, the power cord plug must be

changed to the proper type to match your country and/or electrical
code.
