RESISTANCE ANALYSIS OF ANALOG SECTION

tatic testing of the analog circuits. Do not plug in the power supply into 120VAC power source until all

esistance readings check out. The values given below are approximated.

SET SW3 TO SQUARE WAVE (refer to top panel)

From To Circuit Ohms Resistance Measured

Pin 11 (U6) Pin 3 (U10) Square Wave VR5 CCW 12.3kW

Pin 11 (U6) Pin 3 (U10) Square Wave VR5 CW 6.7kW

SET SW3 TO TRIANGLE WAVE

From To Circuit Ohms Resistance Measured

Pin 2 (U6) Pin 3 (U10) Triangle Wave VR5 CCW 14.7kW

Pin 2 (U6) Pin 3 (U10) Triangle Wave VR5 CW 4.7kW

Pin 13 (U6) Pin 14 (U6) Triangle Wave Greater than 1kW

SET SW3 TO SINE WAVE

From To Circuit Ohms Resistance Measured

Pin 2 (U6) Pin 3 (U10) Sine Wave VR5 CCW 14.7kW

Pin 2 (U6) Pin 3 (U10) Sine Wave VR5 CW 4.7kW

Pin 13 (U6) Pin 14 (U6) Sine Wave 200W

Pin 3 (U6) GND (B1) Mult VR8 CCW < 10W
