Your new 3468A/B is a fully programmable HP-IL digital multimeter. HP-IL (Hewlett-Packard Interface Loop) is a serial interface allowing the -hp- Model 41C/CV family of calculators or desktop computers such as the -hp- Model 85 to control your 3468A/B. In an automatic test or on the bench, the 3468A/B offers 3 1/2 to 5 1/2 digit resolution for measuring dc volts, true RMS ac volts, 2- and 4- wire ohms, and dc and RMS ac current. The 3468A/B offers dc voltage performance from 1µvolt sensitivity up to 300 volts (full scale), true RMS ac voltage capability up to 300 kHz, and resistance measurements from 1 mΩ sensitivity to 30MΩ (full scale). Its dc and true RMS ac current measuring capability is from 10µA sensitivity up to 3A. The optional battery pack provides up to 5 hours of continuous portable operation. By selecting the number of digits displayed and using the autozero feature, the 3468A/B allows you flexibility in measurement speed and accuracy. Up to 31 readings per second can be made with the 3468A/B in the 3 1/2 digit mode. The fast autorange feature of the 3468A/B allows fast bench measurements over a wide dynamic range. The alphanumeric Liquid Crystal Display (LCD) gives you measurement units as part of the reading for easy-to-read, unambiguous answers. The HP-IL talk, listen, remote, and SRQ status information is also available with LCD annunciators. The SRQ button can be used to flag or interrupt your calculator from the front panel of the 3468A/B. Furthermore, to lower your cost of ownership, the 3468A/B is calibrated electronically, either manually from the front panel or remotely in an automatic calibration system. There are no internal adjustments and the calibration of all functions is done without the removal of covers. The self-test function verifies most of the internal circuitry of the 3468A/B indicating proper operation of the multimeter.
