Application Notes
3. Repeat Procedure 16. (Figure AN1006.17)
Procedure 19: V
To measure the V
1. Set Polarity to (–).
2. Set Step/Offset Polarity by depressing Invert (release but-

Quadracs
Quadracs are simply triacs with an internally-mounted diac. As
with triacs, Quadracs are bidirectional AC switches which are
gate controlled for either polarity of main terminal voltage.
To connect the Quadrac:
1. Connect Trigger to Base Terminal (B).
2. Connect MT1 to Emitter Terminal (E).
3. Connect MT2 to Collector Terminal (C).
To begin testing, perform the following procedures.
Procedure 1: (+)V
Note: The (+) and (-) symbols are used to designate the polarity
of MT2 with reference to MT1.
To measure the (+)V
1. Set Variable Collector Supply Voltage Range to appropri-
2. Set Horizontal knob to sufficient scale to allow viewing of
3. Set Mode to Leakage.
4. Set Polarity to (+).
5. Set Power Dissipation to 0.5 W. (0.4 W on 370)
6. Set Terminal Selector to Emitter Grounded-Open Base.

ate Max Peak Volts for device under test. (Value selected
should be equal to or greater than the device’s V
trace at the required voltage level. (The 100 V/DIV scale
should be used for testing devices having a V
600 V or greater; the 50 V/DIV scale for testing parts rated
from 300 V to 500 V, and so on).
