The HM 8115-2 is an easy to operate power meter for laboratory and monitoring purposes of good accuracy. Autoranging minimizes operator engagement. The simultaneous display of voltage, current and power is especially useful for monitoring. The RS-232 interface allows the transmission of data from and the control of the instrument hence its integration into automated test systems.
