Digital Laboratory Scale
laboratory-related circuits. please reply. thanks. !?

1.) You can use the same calibrated scale in the range of 3-V as the range 300 V with a voltmeter? explain. 2.) This means zeroing an ohmmeter? How do you do? 3.) What is the difference between reading an electronic voltmeter analog and digital voltmeter? 4.) Unknown voltage (known only to be less than 600 V DC) is measured by a voltmeter CC has the following ranges: 600, 300, 60, 15, 3. Explain how you could measure this voltage with the voltmeter. 5.) List two advantages of a regulated variable supply DC power on batteries.

1. yes. Because that's the way it is designed. 2. connect a short circuit between the cables and adjusting the control so that the meter reads zero 3. It should be obvious 4. start with the range of 600 volts, and if it reads less than 300, reduce the scope of one. If you read less than 60 years, reduce again. If <15, reduced again. If <3, reducing again. 5. Voltage is kept constant with the load, and remains constant over time, and needed no replacement. .
