For the purposes of current measurement has provided various types of ampermeter, for the measurement of direct current and alternating current, and for the purposes of precision measurement and for the purposes of electrical panels. Here is an example of the various types of ampermeter available in the market for various purposes. Whether operating in an analog, ie using a stylus, and which operate digitally.
Figure 6.13 shows the standard analog ampermeter with high accuracy, to measure direct current and alternating current.
Ampermeter of this type can be used as a calibrator. Medium Figure 6:14 shows the secondary analog ampermeter with low accuracy, to measure direct current and alternating current. Ampermeter of this type are commonly used in the electrical panel.

Direct Current Measurements
Ammeter ampermeter with disabilities to be able to measure the current, prisoner in Rm meter limit the ability of the limit measure. Raising the limit measure carried denganmemasang parallel prisoners Rp denganampermeter. Prisoners Rp energized by Ip, yangmelalui flow meter for Im Rm.
