LKG 610

6. Leads Isolation Test:
Plug the ECG device into the LKG 610. Connect the ECG leads. Press the “ISO TEST”
key. The isolation leakage will be presented on the display in
µ
Amps.
After 30 seconds the LED will begin flashing to indicate that the applied isolation voltage
has been removed. The previous leakage measurement will be displayed. To perform
another ISO test press the “ISO TEST” key again.
WARNING:
Since the test method injects potentially hazardous current levels into the ECG
and related power system, do not conduct tests in an occupied patient location or
while the patient is connected to a related power system branch.
CAUTION
During Isolation leakage measurements the LKG 610 introduces line voltage into
the patient leads. Even though it is current limited to 1milliAmp, it is potentially
lethal.
7. Case Leakage Current:
The Case Leakage Current is measured through the test lead cable. Connect the test
Lead to the case of the DUT(Device under test). The leakage measurement is made
when the CHS GND switch is momentarily switched to the LIFT GRND position. The
display will present the measurement in Micro Amps. No other connection is required.
To measure the Case Leakage of devices with plastic enclosures, wrap aluminum foil
around the case of the DUT and connect the test lead to the foil.
8. Point To Point Testing:
Use two 503 test leads plugged into the “REF GND” and “CHASSIS” EXTERNAL
INPUT jacks. Push the CASE LKG key. The display will present the measurement in
microAmps.
Note: “OL” displayed in any measurement function indicates an over range
condition.
