Ammeter shows the power charger or discharge current in the circuit
battery and has a two-way scale with a scale of 10 A.
On the scale of the digits: -20, 20.
The ammeter is a magnetoelectric device. The principle of operation of its
based on the interaction of the magnetic field of permanent magnet and the iron
chelae of the mobile device.
If the current through the ammeter does not pass, the needle, mounted on the chelae,
under the influence of the permanent magnet (placed inside the unit) is installed
If the current passes through the ammeter on the battery (discharge current)
ammeter needle is deflected to the left of zero. If you pass through the ammeter
current from the generator (charging current), the ammeter needle is deflected to the right of
Ammeter is designed for a nominal strength of the current 20 A.
The permissible error of the ammeter readings, A, is given below.
Display of audited unit ................................... 20
The true value of the current strength of the control unit .............. 17-23
When turning off the current ammeter needle should be installed within the
zero of the scale.
