Shortcut Key 2: Insulation Resistance Test
The Insulation Resistance Tests measure (in Megohms) the resistance from DUT
outlet L1 and L2 to DUT Earth, or from applied parts to DUT Earth. The
measurement is taken with a test voltage of 500 Volts DC. The test will not begin
until START TEST ( SOFT KEY 1 ) is pressed. Once running, display values are
updated continuously and the unit will beep repeatedly as long as a test is active.
The test lasts for 60 seconds in Manual and Step modes, and 6 seconds when
running in Auto mode unless the operator terminates the test by pressing the STOP
TEST ( SOFT KEY 1) or the esc/stop key.
Important: This test is acceptable per IEC 601-1 for non-manufacturers' retesting
of devices. The standard specifically indicates that this test should not be carried
out at the full voltage used by manufacturers to stress the DUT.
The front panel outlet is turned off during this test. The following conditions apply:
• L1 and L2 Open with 500VDC applied between L1 and L2 to Earth
To perform an Insulation Resistance test (L1 and L2 to Case) using the shortcut
keys:
• From the MAIN MENU , or with the outlet unpowered, plug the DUT into the
601PRO front panel outlet with the DUT’s power switch ON.
• Attach the device's applied parts to the 601PRO's applied part terminals.
• Press
shortcut key 2 . The Insulation Resistance test is displayed:
baw050f.eps
• Press START TEST to start running the test.
• SOFT KEY 1 starts or stops the test.
• SOFT KEY 2 changes the test to AP to Insulation Resistance.
• The unit will beep repeatedly as long as the test is active.
• Press STOP TEST soft key to terminate the test.
• Press the print data key at any time to generate a printout of the latest
measurement(s) .
Important: A 2-beep-per-second signal indicates high voltage
present at the DUT Outlet and at the applied part
terminals. In Auto Step tests, the applied parts
insulation resistance test will apply high voltage to all
