§
Digitally controlled arc
detection system
Allows the operator to select whether low-level arcs
should be detected and provides the operator with the
ability to digitally select and program multiple sensitivity
levels.
§
Electronic ramping (up and
down) Provides a gradual and timed method to increase or
decrease output voltage to the DUT, minimizing any
damage from quick high voltage changes to sensitive
DUT’s.
§
Built in VERI-CHEK

self
verification system
Some safety agencies require that the Hipot tester be
checked and verified at various intervals. VERI-CHEK
is a menu driven process by which the instruments
failure detectors are proven to be functioning properly,
“Verifying” the functionality of the electrical safety
tester and connected accessories.
§
Extended IR measurement
range
The Insulation Resistance measurement range of the
HypotULTRA III allows for measurements up to 50
Gigohms.
§
Remote Interlock The remote interlock utilizes a set of closed contacts to
enable the instruments output. The system employs a
fail-safe interlock, if the interlock is open, the output of
the instrument is disabled. This input can be wired to a
protective device to prevent activation of high voltage
unless a safe test condition is detected.
