2.3.6 Using the Bias Feature
TO AVOID PERSONAL INJURY FROM ELECTRICAL SHOCK OBSERVE SAFETY
PROCEDURES AS NEEDED FOR THE BIAS VOLTAGE APPLIED.
Bias voltage is necessary or desirable when measuring the capacitance of diodes or of some
electrolytic or tantalum capacitors.
There is a provision on the rear panel for connecting an external bias source of zero
to 50VDC. Remove the shorting link between BIAS terminals when using this feature.
If the external bias supply is not a low AC impedance type, it should have a capacitor
bypass of five times the range full-scale value connected across the bias terminals. The
bias supply should be current limited to 0.1A maximum.
With no bias supply connected, the rear-panel + and – terminals must be strapped
together.
