Software Voltage Limit, nominal
The product offers the opportunity to change the maximum settable voltage on a temporary
basis. The MAX VOLT menu entry, when set below hardware maximum limit, disallows
adjusting the product to voltages in excess of the MAX VOLT limit.
Cleaning Requirements, nominal
Inspect the power supply as often as operating conditions require. To clear the exterior
surface, perform the following steps:
1. Remove loose dust on the outside of the power supply with a lint free cloth. Use care to
avoid scratching the display.
2. Use a soft cloth dampened with water to clear the power supply. Use an aqueous solution of
75% isopropyl alcohol for more ef
fi
cient cleaning.
Caution: To avoid damage to the surface of the power supply, do not use any abrasive or
chemical cleaning agents.
Caution: Avoid getting moisture inside the unit during external cleaning. Use only enough
cleaning solution to dampen the cloth or swab.
