INDUCTOR, CAPACITOR AND RESISTOR MEASUREMENT DIGITAL METER: For all ECE & EEE Engineering and Polytechnic college Lab unknown RLC value testing use: Features: Inductance (L) Capacitance / Resistance Inductor Range Accuracy Measuring frequency 2mH ±2.0%+5 1uH Approx:200Hz 20mH 10uH 200mH 100uH 2H ±5.0%+5 1mH 20H ±5.0%+15 10mH Capacitor Range Accuracy Resolution
Place the voltmeter across the circuit or component whose voltage is to be measured. Wrong polarity causes the meter to deflect against the mechanical stop and this may damage the pointer. using a multi range voltmeter, always use the highest voltage range and then decrease the range until a good up-scale reading
DMM: 3¾ Digital Multimeter:- Measure Direct Current Voltage, Alternate Current Voltage, Direct Current resistance,capacitance,frequency and temperature. 3¾ Digital multimeter with maximum reading of 3999 Measure resistance,capacitance. frequency and temperature Tests diode, transistor and continuity Data hold Range selection automatic and manual Large LCD display (Size 70X50mm) Low
PRECAUTIONS WHEN USING A VOLTMETER & AMMETERS Observe the correct polarity. Wrong polarity causes the meter to deflect against the mechanical stop and this may damage the pointer. Place the voltmeter across the circuit or component whose voltage is to be measured. When using a multi range voltmeter, always use the highest voltage
O-30V DC SINGLE Or DUAL TYPE VARIABLE POWER SUPPLY. When the selection of power supply specifications, the following questions must be need: How much current does the system require How much ripple voltage can be tolerated? How much voltage drift with temperature is acceptable? Do we use one

The DSO is based on the familiar practices of traditional instruments, users can use the new units without spending considerable time in learning and familiarizing with operation. For faster adjustment to ease testing there is an AUTO key to instantly display the appropriate waveform and range position. FUTURES:- 500MS/s real time sample rate
