Chroma 19070 Sentry Hipot Tester AC/DC/IR 19071 19073

Description of Chroma 19070 Sentry Hipot Tester AC/DC/IR 19071 19073

The Sentry 19070 Hipot Tester series provides 2 models to choose from. The Sentry 19071 for AC Hipot testing; and the Sentry 19073, which combines both AC and DC Hipot with insulation resistance (IR) measurements into a single compact unit.

The O.S.C function is used to check whether the connection is an open connection or that a short circuit exists between an instrument and DUT (equipment under test) before the Electrical Safety Test. If there is a bad connection between the instrument and DUT, for instance a bad lead or relay oxidation, the test will also PASS. In some cases, the DUT has a short before testing. In this case, testing can lead to a broken test instrument due to the high load current. Therefore, our test devices check for open and short circuit conditions to ensure effective testing and protect instruments.

Generally, DUT have capacitive load (Cx) from tens to thousands of pF. If there is an open connection, a capacitance will appear and total capacitive load will be lower than normal conditions. If the DUT is shorting, total capacitive load is higher than that in normal conditions. Therefore, we can measure the value of capacitive load to check whether the contact is good or not.
