OPERATION
67
DO NOT CONNECT VOLTAGE OR CURRENT TO THE SIGNAL
INPUTS, THIS COULD RESULT IN DAMAGE TO THE CONTROL
CIRCUITRY.
MEMORY ONE - Momentarily connecting terminal 7 to 8 signals the instrument to
immediately begin the test program that is stored in memory one.
MEMORY TWO - Momentarily connecting terminal 7 to 9 signals the instrument to
immediately begin the test program that is stored in memory two.
MEMORY THREE - Momentarily connecting terminal 7 to terminals 8 and 9
signals the instrument to immediately begin the test program that is stored in
memory three.
7. Adapter Box Connection
The following diagram shows how to connect the adapter box to the HypotULTRA
II or QUADCHEK II and to the device under test.
The adapter box provides an easy way to connect an item which is terminated in a
two or three prong line cord. If you are testing a product which is terminated in a
three prong plug, you are also required to perform a continuity or ground bond test
on the ground conductor of the DUT to the chassis or dead metal of the product.
With HypotULTRA II, you can perform both the hipot and continuity tests at the
same time by activating the continuity function on the instrument.
When the HypotULTRA II tests the ground conductor of the line cord, if the
resistance of the ground conductor exceeds 1
W
, the hipot will signal a continuity
