AVO meter is a
tool to measure current, voltage and electrical resistance. AVO meter is short
for Ampere Volt Ohm meter. There are two types of the AVO AVO meter analog
meter (zoom in the form of needle play) and AVO meter digital (digital zoom of
display). Sometimes people call AVO meter with multi tester. In use it is important to pay attention to and to choose the appropriate
measurement scale before making measurements. Get used to using the highest
scale at the beginning of both the current measurement, voltage or electrical
resistance. Furthermore, the scale could be lowered if the measurement is still
perceived inadequate level of accuracy.
For instance, we use an analog AVO meter to measure the voltage on an AC voltage source. We place the switch in the position of VAC (for voltage measurement AC), select the highest scale. View deviation needle is enough to be able to read or deviation is too small so difficult to read. If the deviation of the needle is too small then we can measure the scale down again to get the deviation that can be read properly. Do not choose a scale that is too small so that the needle deviated beyond the maximum limit of measurement, it can damage the AVO meter. It's also important that we pay attention to the polarity when measuring current and voltage associated with DC. Do not be reversed because it can also damage the AVO meter.
For analog meter AVO AVO meter is also important to calibrate before use to make measurements, particularly in measuring the resistance (resistor) for accurate measurement results. How to connect and play tap2 AVO meter penepat not (calibrator) until the needle right shows the number 0 ohms, then ready for use. If the scale of measurement is usually modified to be calibrated again.
For AVO digital meters are usually equipped with the ability to measure the capacity of a capacitor and a transistor HFE, and without the need to be calibrated. Looks like it is more practical but the price is also more expensive practical.
But there are also analog AVO meter with a particular brand is quite expensive because it is reading accurately and good results, just read it must have looked tetep deviation needle
Well to be here first a brief description of the AVO Meter lesson we'll go again. Good luck ........
