To run a Power Distribution Test, perform the following
steps:
1. Press F2 until an asterisk (*) symbol appears
following ‘Mode’.
2. Rotate the encoder knob until the *Power Dist test
mode appears on the screen, and then press the
Enter key.
3. Press SETUP (F4) to access the setup menu for this
test.
4. Set the Start Load, End Load, and Step Size for the
test. Use the KNOB PARAM. (F3) key, the encoder
knob, and the Enter key to make and confirm
selections. Press QUIT MENU (F4) when set.
5. Set and activate the ESU using the Analyzer foot
switch control instructions found later in this manual.
W Caution
If you cannot connect to the foot switch
control, you may be able to keep the ESU
activated throughout the test. However,
please check with the ESU manufacturer
prior to triggering for a prolonged period in
this fashion; damage to the ESU could
otherwise result.
6. Press START (F3) to begin the test. The Analyzer
steps through the loads with a delay between each,
as set in the test SETUP screen. The Analyzer
displays values on the screen for each load as it
steps through the test.
(If connected to a printer, the Analyzer writes a line of test
results for each step in the Power Distribution Test.)
HF Current Leakage Test
This test checks whether the active and dispersive
leakage currents are within acceptable limits. There are
four test setups to accomplish this testing.
The ESU must operate at the maximum output setting in
each operating mode per IEC 601-2-2 and ANSI/AAMI
HF18-2001 specifications. The limits for the acceptable
leakage currents depend upon the test configuration as
shown in Table 4.
