What is Recording Instrument?
A recording instrument is that continuously records the data or variation in any electrical quantity(current or voltage) with respect to time. Recording instruments are available in both analog and digital devices. The stores the data in the form of letters on paper, or electronic signals. For example, an analog graphical temperature meter has graph paper and pen, the pen will draw a continuous graph according to changes in temperature over time. So after we can read this graph to know at which time how much temperature was.
Digital recording instruments have a memory so they store the data in the form of electrical energy. Digital recording instruments can store data over a long time than the analog recording instruments.
Recording instruments are used to record our present activity or multiple activities over a long time. So, we can analyze the data in the future and take decisions based on it.
Difference Between Recording Instrument and Indicating Instrument
Indicating instruments measure data in every fraction of time but they did not store any data. So we can always shows the present data or value, here we cannot able to see the previous or past data. On the other hand, the recording instruments measure the data or value in every fraction of time but the difference is they record each data with respect to time. So here we can get the present data as well as past or previous data. Ammeter, voltmeter, wattmeter are examples of indicating instruments. Actually, the recording instrument is the combination of indication instrument with a data storing or writing mechanism. Where indicating instruments measure the data in every fraction of time and the storing function records the data over time. Both of the devices has their own important applications and uses.
