What s new with QUADCHEK II, 7504SA and HypotULTRA II, 7550DT.
·
Optional built-in scanner interface-
These instruments now offer the capability of
easily and quickly testing multiple products or multiple points with a single instrument.
These instruments include an interface to allow control of up to two external scanners
for a total of 16 port control through the instrument without any additional interface
requirements.
·
HS-8A & HS-16 External Multiplexer Scanners -
Two new optional external
scanners are available for either instrument. The HS-8A features 8 high voltage and 8
ground bond ports. The HS-16 has 16 high voltage and 16 ground bond ports. In
addition, it may be controlled by its own built-in GPIB or RS-232 interface providing
complete automation control and flexibility.
·
RS-232 Interface -
The standard interface on these new models continues to be GPIB
(IEEE-488). However, the instruments are now offered with the option of an RS-232
interface instead of GPIB to maximize their interface flexibility.
·
Single 2 X 20 LCD display -
A single easy to interpret display makes setup of the
instrument simple. All functions and test results are clearly displayed without multiple
displays and hard to understand abbreviations.
·
Quick access user interface -
To make access to each function of the instrument
easier we have now configured the instruments with dedicated hot keys that quickly
allow the user to step through each mode of the instrument without having to scroll
through the entire menu.
·
Enhanced storage capability -
The total number of setup memories have been
increased to 50. In addition, each memory can include up to 8 steps which all can be
linked together for a maximum of 400 steps in sequence.
·
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.
·
Exclusive Charge-LO function -
This new function enhances DC hipot testing by
ensuring that the DUT is connected properly. A problem with LO-Limit detect
circuitry in DC applications is that once the DUT is fully charged steady current is
normally well below the range of LO-Limit detect circuitry. This new feature
monitors the momentary charging current pulse and uses it to detect whether the DUT
is connected. The Charge-LO function has an auto setup mode so the user does not
