6.5 Current Leakage Test
Tools required: Calibrated leakage tester
Set-Up
1. Connect the controller to the primary power source through an
ungrounded adapter plug so that the unit is ungrounded.
2. Turn the Power switch on.
NOTE:
The current leakage test standards, provided in the test procedures
below, assume leakage through a resistance of 1000 ohms.
3. If the leakage tester being used does not provide a resistance of
1000 ohms, adjust the test set-up to provide it.
4. Turn the Power switch off.
NOTE:
The current leakage test standards, provided in the test procedures
below, assume leakage through a resistance of 1000 ohms.
5. If the leakage tester being used does not provide a resistance of
1000 ohms, adjust the test set-up to provide it.
Procedure
1. Use the leakage tester to measure between the chassis of the unit
and a known ground, such as the ground connection of a wall
receptacle.
NOTE:
The leakage current must not exceed 300 uA for 100V AC/120V AC
units or 500 uA for 220V AC/240V AC units.
2. Reverse the plug, and repeat step 1.
3. To ensure proper operation of the Isolette® Infant Incubator,
perform the “Function Checks” on page 2-6.
