TEGAM has released the TEGAM 1740 Milliohm Resistance Meter. In Fast Mode, the 1740 can make 100 readings per second with an accuracy of 0.05%. According to the company, the combination of accuracy and high measurement speed allows users to improve throughput with higher yields in resistor, wire, fuse, thermistor, trimmer and contact-resistance testing applications.
The 1740 uses TEGAM's microohm measurement technology. Patented circuitry rejects thermal and line noise, while compensating for thermal and electromagnetic measurement errors caused by contact between device handlers and the device under test. In delayed mode, the 1740 can make up to 27 measurements/second at an accuracy of 0.02%. The 1740 provides users with ten different ranges from 20 milliohm to 20 megohm full scale. On the 20 milliohm range, the resolution is 1 micro-ohm.
On the bench, technicians can quickly configure the instrument via the front panel. Clearly labeled multifunction keys provide front panel control of range selection, reading modes, delays, triggers and measurement HOLD. For computer-controlled test applications, the 1740/GPIB can be programmed via and data collected from the instrument's GPIB, RS-232, or RS-422 interfaces. Programs use the same programming command set and front panel indicators no matter which interface they use.
