Analog Frequency Meter
Product Code : SCL-LM-11129
Quick answer: The Analog Frequency Meter indicates the frequency of an alternating-current supply in hertz on a graduated analog scale. It is used in physics and electrical laboratories to show what a frequency of 50 Hz means, to check an AC source and to teach students to read an analog scale. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How it is used
In an alternating-current supply the voltage reverses direction many times each second. The frequency f is the number of complete cycles per second, measured in hertz, and it is related to the period T by f = 1/T. The public mains supply in India runs at 50 Hz, so each cycle lasts 20 ms. A frequency meter turns this abstract idea into a reading students can see.
- Check that the supply to be measured lies within the range marked on the meter scale.
- Switch off the supply, then connect the meter across it, in parallel.
- Switch on and read the pointer against the graduated scale in hertz.
- Where the experiment uses a variable-frequency source, change the setting and record the new reading.
Comparing the meter reading with the period measured on a cathode ray oscilloscope is a good exercise in linking f = 1/T to a real signal.
