A vacuum tube voltmeter (VTVM) is just the "old school" version of the newer (cheaper, more accurate and easier to use) digital multimeter (DMM). It is used to measure voltage (AC and DC), resistance, and (usually) current flow. It may have some other functions. For the most part, these meters (the VTVMs) used an electromechanical meter movement (expensive, shock sensitive, sometimes hard t read/interpret) in place of the display of the DMM. And they have some disadvantages over the DMM, as mentioned here and there. (There are a couple of things the old VTVM will do that the DMM has difficulty doing, but the modern DMM is a better meter for almost any application.) The need to make measurements, and, hence, the need for the meter is to support understanding and assessment of electrical "stuff" that needs to be looked at, usually to see why it isn't working properly. The meters are used by builders of electronic and electrical devices, and by the curious who wish to investigate the physics of basic electronics and electricity.
how which is right and which is wrong. You need a voltage standard with that you can calibrate both to the standard
we need vacuum to remove moisture from tank

They need to use- well the best thing/object/equipment for them to use is a voltmeter!

When talking about human resource management or human services there are four main themes that need to be addressed. The four themes are benefits administration, payroll, hiring, and conflict mediation.

Voltmeter connect in parallel with the circuit setting on voltmeter highest range first then to lower range. Ohmmeter we need to use the ohmmeter meter setting connect across the resistor

When a technician uses a voltmeter he or she can measure the power going through a circuit. It can test the safety and reliability of a an appliance also.Another AnswerA voltmeter is used to measure the potential difference, or voltage, between conductors. To measure power (as mentioned in the original answer) you need a wattmeter, not a voltmeter.
