§ Exclusive SmartGFI function The SmartGFI (patent pending) provides maximum
operator protection to the user. If the circuit detects
excessive leakage to ground it shuts down the high
voltage in less than 1 millisecond. SmartGFI is
automatically activated if the DUT is not grounded. The
operator does not need to make the decision whether to
activate the SmartGFI.
§
Programmable security password
system
Avoids tampering with settings by only allowing
authorized personnel with a user programmable security
password to change test parameters.
§ Line and Load regulation Maintains the output voltage to within 1% of setting even
if the load or the line voltage varies. This ensures that the
test results remain consistent and within safety agency
requirements.
§ PLC remote inputs & outputs This allows the instruments to be remotely monitored and
set up completely through simple PLC control.
§ Up to 100mA of current is
available in AC Hipot mode and
3500 µA in DC Hipot mode with
resolutions of 10 microamps in AC
and 1 microamp in DC This makes these instruments true hipot testers with
enough output current to test even highly capacitive loads
while allowing them to be versatile enough to monitor
leakage current of items with very low leakage
measurement requirements. In addition these instruments
comply with agency specifications requiring 500VA
output.
§ 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.
§ Four wire measurement (Kelvin
Method) and milliohm offset
capability in the Ground Bond
mode
The four wire measurement technique eliminates test lead
resistance when using the standard test leads. The
milliohm offset function allows the use of longer test
leads and test fixtures without compromising test results.
