External Point to Point Measurements

The unit has the ability to measure Leakage Current and Resistance between two

points, utilizing two test leads. These tests are separated because they use a slightly

different setup than the previous tests.

Point to Point Leakage Current

With the External function selected, the display will show the leakage current between

the test leads.

The test requires that the Chassis Test lead be plugged into the Chassis Connector and

the External Test lead be plugged into the External Connector. The other ends of the

leads are then attached to the points of interest.

Any current flowing between the test points is passed through a 1000 Ω load with either

AAMI ES1-1993 or IEC 601 frequency compensation as selected by the Load Selection

switch.

Point to Point Resistance

With the Earth Resistance function selected, the display will show the resistance

between the two test leads.

The test requires two Chassis Test leads, one in the Chassis Connector and the second

in the External Connector. The opposite cable ends should be connected to the points

of interest.

NOTE: Remove any device plugged into the Analyzer Test Receptacle. If there is a DC

voltage present between the two test points, the reading may contain an error. This can

be checked by reversing the connections. If the readings differ, average the two to get

the actual resistance value.
