AC/DC/IR HIPOT TESTER MODEL 19070 & 19050 SERIES
The 19050 series electrical safety testers are advanced digital hipot testers with load and line regulation to ensure measurement integrity. Multi- step capability allows users to perform multiple tests in sequence, such as AC hipot followed by IR.
The Chroma Hipot Tester 19050 series provides 3 models to choose from. The 19052 includes AC/ DC/IR Hipot testing and insulation resistance (IR) measurements. The 19053 provides 8 scan channels for IR measurement, and the 19054 provides 4 scan channels for IR measurement in a single compact unit.
The Chroma Hipot Tester 19070 series provides 2 models to choose from. The 19071 is for AC Hipot testing. The 19073 combines both AC and DC Hipot with insulation resistance (IR) measurements into a single compact unit.
Open Short Check (OSC)
The O.S.C function is used to check whether the connection is open, or a short circuit, between the instrument and DUT (device under test) before the Electrical Safety Test is performed. If the connection is bad between the instrument and DUT, like bad leads or relay oxidation, the test may reult in a PASS determination. In some cases, the DUT has a short before testing. Testing continually leads to instrumentation damage due it suffering the high load current. Therefore, we check for the open and short circuit to ensure the test is effective and to protect the instruments.
