These high voltage, multichannel resistance measurement solutions speed and simplify electrical checks of airbag inflators and a variety of other automotive electrical test applications. They combine all the sourcing, measurement, and signal routing capabilities required to measure insulation resistance and conductor continuity in one compact, affordable package. A memory pattern test sequencer allows the mainframe to store and execute pre-programmed test sequences to ensure high testing throughput.
The Model 7702 plug-in module offers 40 channels of 2-pole or 20 channels of 4-pole multiplexer switching that can be configured as two independent banks of multiplexers. The Model 7702 provides two additional protected channels for current measurements. It is ideal for RTD, thermistor, and thermocouple temperature applications.
Key Features | Benefits |
Programmable constant V source (50–500V) | Supports high speed, high resistance measurements. |
Programmable constant I source (0–50mA) with dry circuit clamp | Helps prevent device stress or damage during low resistance measurements. |
Modular architecture | Adapts easily to single or dual inflator testing and to single or dual position test stands and mixed device/signal applications. |
GPIB, RS -232, and digital I/O interfaces | Eases integration with external test hardware. |
2-year module calibration cycle | Reduces maintenance costs and system downtime. |
