HP 4349A 4-Channel High-Resistance Meter
The HP 4349A 4-channel high-resistance meter is HP’s highest throughput high-resistance meter for production testing of capacitors.
High Throughput
To verify component reliability, capacitor manufacturers need to test capacitor insulation resistance at different voltages. The 4-channel configuration permits simultaneous testing of 4 capacitors with different test voltages. This configuration reduces the investment cost when compared to a single-channel instrument. The HP 4349A’s 11 ms 4-channel simultaneous measurement improves the test throughput in a capacitor production line. For insulation resistance testing for capacitor manufacturers, capacitor charge time is a key factor in slowing down measurement time. The HP 4349A’s front end has a 1 k n input impedance that allows the instrument to reduce the capacitor’s charge time, and thus increases test throughput. The Contact Check function verifies that the signal path between the handler and the device under test (DUT) is optimal for a measurement. Contact Checking maintains automatic handlerlDUT integrity while keeping system throughput high.
System Integration
The built-in comparators fOf all 4 channels and the HP-IB/handler interface make system integration with automatic handlers and computers a fast and clean process.
