  • Notes

  • The reading of this voltmeter is displayed in decimal form on five in-line numerical indicators and is also available as a one-in-ten decimal coded output.
    Six ranges are provided, five of which cover the normal range of 10 µV to 1999.9V DC and the sixth offering an external selected scale facility. 
    The polarity of the input is indicated automatically.
    The input impedance of the DM2020 is in excesse of 2000 MΩ on the two lower voltage ranges and the external range. On the other ranges the impedance is 10 MΩ.
    This instrument can be operated in one of six modes:
    1) Single shot reading by external command.
    2) Single shot reading by manual push-button command.
    3) Automatic tracking of input signal variations.
    4) Minimum reading.
    5) Maximum reading.
    6) Continuous operation at 50 reading per second.

    All particular characteristics are in the original attached article.
