It samples at 1 MSa\/s across a DC to 300 kHz bandwidth and resolves current to 0.1 µA and voltage to 1 mV — fine enough to measure milliwatt standby draw and the switching content that an AC line meter averages away.\u003c\/p\u003e\n\u003cp\u003eFour models share one measurement platform. The base UTE310 covers 75mV – 600V \/ 5mA – 20A from a 75 mW floor; the high-voltage UTE310H extends to 75mV – 1000V \/ 10mA – 50A for high-line and high-power work. Either is available with GPIB in place of RS-232 (G\/HG) for instrument-bus automation.

The UTE310 measures to 75mV – 600V \/ 5mA – 20A; the UTE310H extends to 75mV – 1000V \/ 10mA – 50A. The measurement engine, accuracy, sampling and firmware are identical.\u003c\/p\u003e\n\u003ch3\u003eDo the G and HG models add GPIB on top of RS-232?\u003c\/h3\u003e\n\u003cp\u003eNo — they substitute GPIB for the RS-232 port. USB, LAN and Digital I\/O are present on every model. If you automate over LAN or USB you do not need the G\/HG variant.\u003c\/p\u003e\n\u003ch3\u003eCan it measure DC as well as AC power?\u003c\/h3\u003e\n\u003cp\u003eYes.
