Instek GOM-802 30,000 Counts Programmable D.C. Milli-Ohm Meter

The GOM-802 includes an easy to use comparator function (HI-LO-GO) that is able to easily set upper and lower limits for pass/fail testing. The alarm buzzer can be used with the comparator function. The flexible handler interface can be used to monitor the status of the pass/fail testing.

The relative feature enables the GOM-802 to easily compensate for any stray resistance. Up to 20 different sets of HI-LO-GO settings can be stored to satisfy a number of different testing conditions. The GOM-802 is also able to recall the last test setting that was used every time it is turned on.

Performance
The GOM-802 has nine selectable measurement ranges from 30mΩ to 3MΩ, a constant current source of 1uA to 1A, an accuracy of 0.05%, a 1uΩ resolution and performs measurements using four wire Kelvin connections for accurate, consistent measurements.

The ability to choose between high measurement accuracy with 7 samples/sec (full scale at 30000) or high speed measurements with 30 samples/sec (full scale at 3000) allows the GOM-802 the flexibility to fulfill a number of different measurement roles.

Temperature Compensation
Temperature Compensation (Optional):
The optional temperature probe (PT-100) can be used to extrapolate the resistance of a DUT at a certain temperature. When the temperature coefficient and the required temperature (of the resistance measurement) is keyed in under TC mode, the GOM-802 will display the extrapolated measurement.

Automatic Testing
For automatic testing The GOM-802 has a handler interface designed for automatic testing. The handler interface outputs the status of PASS, FAIL, HI, LO, READY and EOT signals and inputs a trigger control signal. An RS-232 and GPIB option is also available for computer control applications.

Applications:

• Production testing for contact resistance of switches, relays, connectors, cables and printed circuit boards and other low resistance devices.
• Component testing of resistors, motors, fuses and heating elements.
• Incoming inspection and quality assurance testing.
• Conductivity evaluation for product design.
