Información

Your new 3478A is a fully programmable HP-IB* digital multimeter. In an automatic test or on the bench, the 3478A 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 3478A offers dc voltage performance from 100 nanovolt sensitivity up to 300 volts (full scale), true RMS capability up to 300 kHz, and resistance measurements from 100µΩ sensitivity to 30MΩ (full scale). Its dc and true RMS ac current measuring capability is from 1µA sensitivity up to 3A. The fast autorange capability of the 3478A allows you to make measurements over a wide dynamic range without sacrificing throughput rates. By selecting the number of digits displayed and using the autozero feature, the 3478A allows you flexibility in measurement speed and accuracy. Up to 71 readings per second can be made with the 3478A in the 3 1/2 digit mode. The 3478A has a fast trigger mode which lets you bypass the built-in settling time delay to make fast true RMS ac measurements in systems applications.
