Introduce the AVO meter or multi tester.

Assalamu'alaikum warohmatullohi wabarokatuh.

Dear visitor welcome to post Maswar service again with the umpteenth time, and this time we will introduce, of course, for the uninitiated, is about AVO meter or multi-meter or a multitester.

Understanding of AVO meter.

AVO meters derived from word "AVO" and "meter". 'A' means amperes, to measure the electric current. 'V' means the voltage, to measure voltage or voltage. 'O' means ohms, to measure ohms or resistance. Lastly, ie meters or unit of measure. Often referred to as AVO Meter Multimeter or multitester. In general, the notion of AVO meter is a tool to measure current, voltage, both alternating voltage (AC) and direct voltage (DC) and electrical resistance. AVO meter is very important function in any electronics work because it can help get the job done easily and fast, but before using it, the user must know in advance the types of AVO meters and how to use them to avoid mistakes in its use and will cause damage to the AVO meter. Based on the working principle, there are two types of AVO meters, analog meters are AVO (using needle play / moving coil) and AVO digital meters (using a digital display). Both types are of course different from each other, but there are some similarities in terms of operations. Suppose a source of energy required DC battery and probe / cable red and black investigator.

At AVO digital meters, measurement results can be read directly in the form of numbers (digits), while analog displays using AVO meter needle movement to show scale. So as to obtain measurement results, should be read by range or division. AVO analog meters are more commonly used because it is cheaper than the AVO type of digital meters. AVO Meter Analog Meter AVO using the needle as a pointer analog scale. To obtain the measurement results, it should be read by range or division. The accuracy of the measurement results of the AVO analog meter is limited by the width of the scale pointer, vibration of the pointer, the accuracy of printing axle, zero calibration, number of ranges of scale. In measurements using AVO Meter Analog, measurement errors can occur due to errors in observation.

Remarks:

1. Meter Corrector, useful for AVO meter needle set towards zero, while AVO meter will be used by turning the screw to the right or to the left by using a small flat-blade screwdriver.

2. Range Selector Switch is a switch that can be played in accordance with the measure limits the ability of the function used to select the measurement position and size limits.

3. Rotary switch (range selector switch) is the key when we use AVO meters. AVO meter usually consists of four measurement positions, namely:

- Position (Ohm) means AVO Meter serves as an ohmmeter, which consists of three measuring limit: x1; x10, and K ohm.

- Position ACV (Volts AC) means AVO Meter serves as a voltmeter AC is composed of five measuring limit: 10V; 50V; 250V; 500V, and 1000V.

- Position DCV (DC Volts) means AVO meter serves as a DC voltmeter consisting of five measuring limit: 10V; 50V; 250V; 500V, and 1000V .

- Position DC mA (milliampere DC) serves as a means of AVO meters miliamperemeter DC consisting of three measuring limit, namely: 0.25, 25, and 500. , but all four measurement above the limit for a single type of AVO meter with another limit is not necessarily the exact same size. The formula to read it is (BU: BS) X AP limit divided measuring scale limit multiplied numbers appointment.

Similarly Maswar post service this time may sapat understood and if want bertanaya can discuse on face book.

Wassaslam.
