Operating Instructions
Testing Procedure
1. Start with all switches upward for 0 ohms.
2. Turn the switches down to add resistance.
3. The ground terminal is connect to the metal enclosure for all of
the switches. In some circumstances the Ground Terminal can
be connected to external equipment to prevent environment
interference.
Note: Do not add more then 50 V DC to the output capacitor
terminals. Do not add more then 250 V AC/DC to the output
resistance terminals, the resistance is less than 1 W.
