The block diagram of the Ramp type ADC is given below. The block diagram of ramp type DVM is shown in above figure. Clock pulses are generated. The ramp type DVM consists of linear ramp this ramp may be positive or negative going. Block diagram of a ramp-type digital voltmeter. No Answers Yet. The voltage to be measured may be AC or DC. DVM is widely used to check if there is power in the circuit, such as mains outlet. ): An integrator (e.g. b. The staircase ramp technique is a simpler version of linear ramp technique. Resolved. V – F CONVERTER TYPE INTEGRATING DVM. capacitor) is either charged negatively from V i or discharged at a constant rate according to the control signal. An electronic time interval counter is used to measure the time interval and the count is displayed in digits as voltmeter output. Ramp type Digital Voltmeter The operating principle of a ramp type digital voltmeter is to measure the time that a linear ramp voltage takes to change from level of input voltage to zero voltage (or vice versa).This time interval is measured with an electronic time interval counter and the count is displayed as a number of digits on electronic indicating tubes of the output readout of the … Thus the voltage can be converted to frequency for the measurement purpose. generates the ramp waveform 2. Its operating principle is based on the measurement of the time it takes for a linear ramp voltage to rise from 0 V to the level of the input voltage, or to decrease from the level of the input voltage to zero. Digital voltmeters of potentiometer type 4. Ramp type DVM Navodaya Institute of Technology Raichur. There are some advantages of ramp type DVM (digital voltmeter) which are given below,It has a better resolution and it can be adjusted because the resolution of digital readout is proportional to the frequency of local oscillator. At the same time, a reset pulse is generated which returns all the DCU s to their 0 state, removing the display momentarily from the indicator tubes. The principle behind this equipment is simple, it takes the value of input voltages and measures the time to take input voltage to reach zero volts or vice versa.

Block diagram of a ramp-type digital voltmeter. The output signal of two comparators is given to the logic control unit which is used to open or close the gate. RAMP type DVM 5. ; The polarity of the signal which is to … Ramp Type DVM • Ramp type uses comparison of input voltage with Ramp waveform. 3. These instruments measure the electrical potential difference between two conductors in a circuit. It has two major sections as the voltage to time conversion unit and time measurement unit. RAMP type DVM 8. Time measurement section IRISET. Potentiometric type digital voltmeter(DVM): In the previous posts we have already discussed working of digital voltmeter and its types, now we will discuss Potentiometric type digital voltmeter. This time interval is measured with an electronic time interval counter and the count is displayed as a number of digits on electronic indicating tubes. Voltage to time conversion section 2. Block diagram of a typical ramp-type dvm. a. 2. Advantages 4. State its advantages and disadvantages. The swing of ramp take place between + 12 V and – 12 V. As shown in above figure the attenuator is placed at the input side and the output of attenuator is connected to input comparator. 4/4/2017 3 NEC 403 Unit I by Dr Naim R Kidwai, Professor & Dean, JIT Jahangirabad + - Ramp generator … Home >> Category >> Electrical Engineering (MCQ) questions and answers >> Electrical Measurements & Units; Q.
