Current
Measured on
electrodes The leakage current should not exceed
150 mA.
Bipolar The leakage current should not exceed
1 % of the maximum bipolar rated
power output.
Measured at

terminals The leakage current should not exceed
100 mA.
Test Procedure
To run an HF Leakage Test, perform the following steps:
1. Connect the Analyzer to the ESU to test leakage
from the Active electrode using the appropriate
setup, as shown under “HF Isolated Equipment” or
“Ground HF Equipment.”
2. Press F2 until an asterisk (*) symbol appears
following ‘Mode’.
3. Rotate the encoder knob until the *RF Leakage test
mode appears on the screen, and then press the
Enter key.
4. Set the ESU as prescribed by the manufacturer for
leakage tests and then activate the ESU.
5. With the ESU activated, press START (F3); the
Analyzer takes the leakage measurement.
6. Repeat the leakage test as needed for other ESU
accessories.
If connected to a printer, the Analyzer writes a line of test
results to the printer following each HF Leakage Test.
Measuring Leakage Current with HF Isolated
Equipment
Make measurements of the HF current leakage from the
active and neutral electrodes. The test load is 200 ohms,
and the ESU must be operating at maximum power.
