Nominal Voltage Ratings
There are two ranges for all models, selectable by the line-voltage selector switch. Check the voltage select switch on the
bottom before turning on: 110 V setting, 110 / 115 / 120 VAC; 220 V setting, 220 / 230 / 240 VAC. Fluctuations must
not exceed 10% of the nominal rated voltage.
Float Voltage Rating
Float voltage rating: up to 100 V (DC + peak AC) between earth ground and any output terminal.
Operating Requirements
1.
Place the instrument on a bench or similar surface.
2.
Before operating, ensure that the ambient temperature is b0 °C and +40 °C (+32 °F to +104 °F).
WARNING.
To ensure proper cooling, keep the front, sides, and rear of the instrument clear of obstructions. Do not
operate the instrument on a table without the handle in the down and locked position. This allows air
fl
ow to the bottom of
the instrument.
