Model 2790 configurations
Model 2790 test configurations available from Keithley include the following:
2790-H configuration (one 7751 module)
This test system includes a single 7751 module. This module has a programmable 50 to
500V V-source and I/V amplifier for HIPOT testing. It also has a programmable 0 to
50mA constant current I-source to measure the resistance of shunt bars and bridgewires.
2790-HH configuration (two 7751 modules)
This test system includes two 7751 modules. When used with a "left and right" type
station, this two-module, high-voltage system allows higher throughput for increased
efficiency.

2790-HL configuration (one 7751 and one 7752 module)
This test system includes a 7751 module and a 7752 module. The high voltage module
(7751) can be used for HIPOT testing, while the I-source of the second module (7752) can
be used to test other non-inflator type circuitry (i.e., pushbutton switches and resistors) on
the steering wheel. The I-source allows accurate resistance measurements up to 100Ω.
2790-L configuration (one 7752 module)
This test system includes a single 7752 module. It is applicable for testing that does not
require high voltage HIPOT testing, but still needs the programmable I-source for low
ohms testing. Insulation resistance (up to 120MΩ) can be measured using the Ω2 function
of the Model 2790.
2790-H/L/A + 7702 configuration (one 7751/7752/7753, one 7702 module)
This test system includes a 7751, 7752, or 7753 module and a 7702 module. The 7702
module can be used for non-inflator related ohms testing that requires 20/40 channels of
4-wire/2-wire measurements. Typical tests using the 7702 module include burn-in/life/QA
testing of multi-pin connectors, wiring harnesses, power distribution/fuse centers,
switches and relays, and backplanes.
When used with a "left and right" type station, this two-module, high-voltage system
allows two inflators to be tested. It provides higher throughput for increased effi-
ciency. When soaking is required for HIPOT testing, one inflator can be tested while
the other inflator is soaking (high voltage applied).
For a dual inflator, the two high-voltage module system allows parallel "soak and
test" of each half.
