Lead to Earth/Ground Leakage

With the Lead to Earth/Ground function selected, the display will show the leakage

current between the selected lead and Earth/Ground.

Attach the patient leads to the connectors on the top of the Safety Analyzer. The Up

and Down arrow keys may then be used to select any individual lead or all of the leads.

This test should be done for each lead individually and all leads together.

This test measures the leakage current that would flow through the leads if the patient

were to come into contact with Earth/Ground.

Lead to Lead Leakage

With the Lead to Lead function selected, the display will show the leakage current

between the selected Patient Lead and all other patient leads.

Attach the patient leads to the connectors on the top of the Safety Analyzer. The Up

and Down arrow keys may then be used to select any individual lead. Internally, relays

connect the leads as necessary. The LEDs indicate the selected lead.

This test should be done for each lead individually.

This test measures the current that would flow from a lead to other leads. Normally

these are Auxiliary currents from bias, measurement and sensing circuits.

Lead Isolation

With the Lead Isolation function selected and the “ISO” Test key depressed, the display

will show the leakage current between the selected Patient Lead(s) and Earth/Ground.

Attach the patient leads to the connectors on the top of the Safety Analyzer. The Up

and Down arrow keys may then be used to select any individual lead and all of the

leads.

WARNING

The SA-2010 applies 110% of line voltage to the

Patient leads or External test leads during the

Isolation test. Although this is current limited by

a 121 kΩ internal resistor, per standard test

specifications, care should be taken to prevent

contact with this voltage. Do not touch the test

leads, connections or DUT while depressing the

Isolation Test key.
