The 2790 digital source meter switch system provides a high voltage and multi-channel resistance measurement solution for users. It can quickly and succinctly implement the electrical inspection of airbag inflators and other automotive electronic testing applications. It is the only commercial instrument for measuring insulation resistance and wire connectivity, which is based on integrated power supply, measurement and signal routing functions, and has a compact and overvalued encapsulation structure. A programmable high voltage and low current source is provided by using the plug-in power / switch module, which supports switching between multiple channels. This unique multi-function integrated design establishes a new cost-effective standard for automotive airbag inflators and other automotive electronic testing applications.

Main features and advantages:

Single instrument solution for connectivity and hi-pot leakage resistance measurement;

Programmable constant voltage source (50-500V) supports fast high resistance measurement.

Programmable constant current source (0-50mA) has low power circuit clamping function to prevent aging or loss of measured components in low resistance measurement.

The modular structure is suitable for single or double air bag test, single or double seat test bench and device / signal mixed test etc.

The extensible multiplexing channel is suitable for multi-pin testing.

The built-in six-and-half-digit multimeter has a variety of functions and a wide range;

Intelligent automatic control function, easy to use with external test hardware;

GPIBM RS-232 and digital I / O interface provide flexible control options;

SCPI (Programmable instrument Standard instruction) can easily realize code development and subsequent upgrade.

During the calibration period of 2 years, the maintenance cost and system downtime cost are minimized.
