  • The digital voltmeter type DM 2001 provides six operating modes, as follows:
    (1) Single shot reading by external command.
    (2) Single shot reading by manual push-button command.
    (3) Automatic tracking of input signal variations, readings being initiated by changes of the input voltage: readings may also be commanded by use of the push-button.
    (4) Minimum reading in which variations of input voltages are tracked only in a decreasing direction. The pushbutton is used to take an instantaneous reading at the start of a minimum reading sequence.
    (5) Maximum reading which corresponds to (4) but reads increasing deviations only.
    (6) Continuous operation at 50 readings per second: in this mode the push-button may be used to freeze a reading.

    The DM 2001 has a scale of 1599.5, the final number reading 0 or 5 only. Six input voltage ranges are provided, five of these covering the operating range of 50µV to 1599.5V and the sixth offering an externally selected (i.e. elastic) scale. Voltages (DC) are measured with an accuracy of ±0.05% of the reading or the five least significant digits, whichever is the greater. This accuracy is achieved within one minute of switching on. Long-term stability is excellent and the DM 2001 needs resetting only at very infrequent intervals.

    Interference rejection circuits are included which can be switched to one of three modes of operation. The total conversion time is 20msec.
