Dmm in class _ppt
- 1. Pradeep Patil – Flipped Classroom (L1) DOMAIN : Second Year TOPIC : Electronic Instrument – Digital Multimeter (DMM) COURSE : Electronic Instruments and Measurement AFFILIATION : Walchand College of Engineering , Sangli 1 TARGET AUDIENCE : Second Year Electronics Engg students Out-of-class_ppt for video - v2
- 2. In-class Activity Design -1 (L1) 1. Recall the need of electronic / digital instrument. 2. To draw the Block diagram of Digital MMM and understand the working of each block and solve the resolution problem. 3. List / write the specifications of DMM. 1. Electronic / Digital instruments & its blocks in block-diagram 2. Digital Multimeter (DMM) 3. Specifications of DMM Learning Objective(s) of In-Class Activity: OER_Flipped_Classroom_activity_construct or 2 Key Concept(s) to be covered:
- 3. Digital Multimeter (DMM) – Functions Can measure – 1) DC voltage , 2) AC voltage 3) Current , 4) Resistance
- 4. Block diagram of Digital Measurement System
- 5. • In digital instrument (DMM) , analog to digital (ADC) is required & parameter is displayed in terms of digits on digital display. • Input requirement for ADC is dc voltage. Basic block – ADC ( DC DVM)
- 6. Additional blocks – To measure AC voltage - ? To measure current - ? To measure resistance - ? Basic block – ADC ( DC DVM)
- 7. • For 3 and ½ digit display , count will be from 0000 to 1999. • So , resolution will be -- n = 3 R = 1/ 10 3 = 0.001 Volts
