Ramp type dvm uses

WebbBasically it consists of a linear ramp which is positive going or negative going. The range of the ramp is ± 12 V while the base range is ± 10 V. The conversion from a voltage to c1 time interval is shown in the fig . At the start of measurement, a ramp voltage is initiated which is continuously compared with the input voltage. WebbThe operating principle and block diagram of a ramp type DVM are shown in Figs 5.1 and 5.2. The ramp may be positive or negative; in this case a negative ramp has been selected. At the start of the measurement a ramp voltage is initiated (counter is reset to 0 and sampled rate multivibrator gives a pulse which initiates the ramp genera-tor).
