Information:
                                    The ESI Model 300 Potentiometrie Voltmeter Bridge is a
battery-operated multiple-use dc measurement instrument. It
combines in the same case a five- range potentiometric
voltmeter, a three-range precision voltage source, an
eight-range ammeter, a ten-range Kelvin double bridge for
two-, three-, or four-terminal resistance measurements, a
four-terminal resistance comparison bridge, a ratiometer,
and a high-sensitivity electronic null detector.
