Fluke 5220A Transconductance Amplifier

The Fluke 5220A Transconductance Amplifier lets you calibrate alternating or direct current meters and shunts and the current functions of digital multimeters that measure up to 20A. A known input voltage of 1 to 20 volts produces a known output current of 1 to 20A. The 5220A is designed for those applications where 20A ac or dc current is required; for example, calibration of the upper ranges of digital multimeters, or used with a current coil to calibrate clamps and clamp meters.
