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.
