1.1 An Overview of Product
The 16502 Milliohm Meter is an automatic instrument used for measuring and analyzing
resistance. The unit was designed to solve the problems of low labor efficiency and low
product quality that have occurred since the electronics sector began to flourish.
The measuring functions included in this unit are versatile inductive components: DC
resistance precision measuring of Cable, Connector, Relay contacts and conductor material
which supply the perfect functions on the production line and in quality control.
By using auto mode of the internal control and measuring function of programmable mode,
the unit can support highly accurate, convenient, fast and reliable testing at low cost. The
functions are as following: Hi or Lo-limit comparison and binning test, testing signal mode
selection, data store memory, GPIB interface control 16502 and data transfer, and statistics
analysis function from PC. The unit can send the test results to an external unit for checking
the response of the component by handler interface.
The multi-functions testing device, ergonomics keyboard design, guided panel operation,
extra-large LCD, and password protection makes the 16502 easy to operate and the test
results are clearly showed on thr display.
The basic accuracy is 0.05%. The measurement device (optional) can perform the calibration
by keying-in the measuring parameter. The calibration procedure can be finished easily for
users by offering ZERO.
