3.7 IMPEDANCE TEST
Connect a variable resistor box to the ECT stimulus cable. Set on zero ohms and push the
impedance test button the readout should be 0_ ±100_. Repeat for 1000_ and 2000_. At
impedances higher than 3000 _ the display will read >3000 and blink.
CAUTION: DO NOT PRESS THE TREAT BUTTON DURING THIS TEST. THE
LARGE POWER OUTPUT COULD DESTROY YOUR RESISTANCE BOX.
