Traceable® Products Model 3250 数字电阻表

Designed specifically for checking the electrical functions of scientific equipment in laboratories. Perfect unit to test batteries, fuses, recorder outputs, cables, wall plugs, probes, printed circuit boards, and complex electronic instrumentation. Save money and time by solving problems and eliminating costly repairs. Unit ranges are from 1 millivolt to 400 volts AC\/DC and 0.1 to 2,000,000 ohms. Accuracy is 2 units, or 2% of the reading. The multimeter instantly displays the correct answer by automatically selecting the proper range. Four-digit, 3\/8-inch-high LCD display shows the exact resistance or voltage unit and indicates negative polarity with a minus sign. To assure accuracy an individually serial-numbered Traceable® Certificate is supplied to indicate traceability to standards provided by NIST (National Institute of Standards and Technology). Features an audible beep for checking continuity, ensuring instant detection of shorts\/opens in probes, cables, or circuit boards. Sampling rate is twice a second. Intuitive operation makes directions almost unnecessary. Comes complete with case, batteries, pair of needle probes, pair of alligator probes, and instructions. Size is 2-1\/8 x 4-1\/4 x 1\/2 inches. Weight is 3 ounces. Replacement battery Cat. No. 1039.
