The Model 2790 is available in a variety of configurations to match specific application requirements:

• The Model 2790-H is a single-module system designed for both low current and high voltage ohms (10MW to 1GW) applications . This “base” system provides all the capabilities needed for electrical testing of either single- or dual-stage inflators in single position test stands (for example,test stands that test only one single- or dual-stage airbag at a time) .

• The Model 2790-A, which is similar to the Model 2790-H, enables high voltage ohms measurements down to 1MW .

• The Model 2790-HH is configured for applications that require parallel testing or high voltage “soaking .” Like the Model 2790-H, it is designed for both low current and high voltage ohms applications and can test either single- or dual-stage inflators . However, with two plug-in modules,it also has the capacity to test two inflators at once, maximizing test throughput .

• The Model 2790-HL is designed for applications where it is preferable to segregate high voltage sourcing/ohms measurement and low current sourcing/ohms measurement into two separate modules . This design was developed for use in combination testing applications, such as inflator electrical checks of safety steering wheel or seat assemblies that also include switch or other ancillary device tests .

• The Model 2790-L is configured for low voltage source/ohms-only measurement applications,such as continuity-only testing of side/seat airbags and seatbelt pre-tensioners or other programmable I-source resistance applications in which high voltage resistance testing is not

required but precise control of source current is .

• With the addition of a Model 7702 40-channel differential multiplexer module (part of the Integra family of switch/measure solutions), the Model 2790-A, -H, or -L + Model 7702 opens the door to higher channel count applications, such as hi-pot/continuity testing of connectors, harnesses,and power distribution devices up to 500V (internally sourced) up to 40 channels .
