To raise the prisoners in the meter, Rm meter in front of prisoners are often added to the series prisoners Rv.<\/span> So the prisoners in the new meter becomes larger, namely (Rm + Rv) .Tahanan parallel Rp remain energized Ip, while the current through (Rm + Rv) of Lev.<\/span>

Equation custody parallel Rp can be written as follows:<\/span>
\n<\/a><\/p>\n

Example:<\/span>
\n Ampermeter with prisoners in Rm = 100 \u03a9, the current allowed through the meter Im = 0.6 mA.<\/span> Ampermeter will measure the current I = 6 mA.<\/span> Calculate parallel prisoners Rp.<\/span><\/p>\n

Answer:<\/span>
\n<\/a><\/p>\n

In fact, to increase the effectiveness of measuring instruments, especially in getting the limit measure the width, typically measuring instrument designed to have multi-limit measure, through the selector switch measuring limit.<\/span> For example a ampermeter with three measuring limit, has three types of parallel prisoners.<\/span> The switch in positions 1 to obtain a first scale measuring limit.<\/span> The switch in position 2 has been given custody of parallel 2 to obtain a second measuring limit.<\/span> And switch at position 3, to obtain a third measuring limit.<\/span> Figure 5.19 shows the principle of the meter.<\/span>

In fact, to obtain three limit measure can also be applied with Ayrtone method, as shown in Figure 6.22 With different methods with the aim of expanding the measuring limit, used three tahananparalel Rp1, Rp2, and Rp3 are connected three series.<\/span> Switch positions 1, prisoners (Rp1 + Rp2 + Rp3) parallel with the circuit (Rv + Rm).<\/span> The switch positions 2, prisoners (+ Rp2 Rp3) parallel with the circuit (Rp1 + Rv + Rm).<\/span> When the switch position 3, prisoners Rp3paralel with the circuit (Rp1 + Rp2 + Rv + Rm).<\/span>

So that the meter can be used to measure the magnitude of electric current bolakbalik, it is necessary to install the diode rectifier as shown in Figure 6:24<\/span>
