Selecting the Voltage Setting and Installing the Fuses

The Saturn DigiSizer leaves the factory set for 120 VAC and with the line fuses removed. The
correct setting of the universal power entrance must be checked and the appropriate fuses
installed before the analyzer can be operated.
The Saturn DigiSizer is designed to operate with 100, 120 or 220, 240 VAC from 47 to 63 Hz.
Voltage selection and fusing are made at the power connector located on the rear panel of the
analyzer. Appropriate fuses are included in the accessories kit:
• Two 5x20mm, SLO-BLO, 1.6A (100 - 120 VAC)
• Two 5x20mm, SLO-BLO, 1.25A (220 - 240 VAC)
1. Make sure the power cord is not connected.
2. Check the voltage setting at the power connector on the rear panel of the instrument.
• If the voltage is correct:
a. Open the cover by prying the left side of the cover with a pointed object, such as a
small flat-blade screwdriver.

• If the voltage is incorrect, open the cover and remove the fuse block as described above,
then proceed to Step 3.
