• Notes

• This voltmeter uses the dynamometer principle to enable AC and DC voltage measurements. The three ranges are 30V, 150V and 300V full scale deflection. It is a laboratory-grade instrument, with a mirror scale and calibration tracable to the Absolute Volt,  accurate to 0.25% of full scale. There is an internal shield to guard against external magnetic fields.

  The calibration certificate provides polynomial correction equations for each of the three ranges for temperature if not 20 degrees Celcius and for frequency. Using the frequency correction, readings are accurate to 1% to 1000 Hz (measured May 2013).

  The sensitivity of the instrument is low, at 15 ohms per volt.
