Question

may anybody tell me how to work with avometr?

Answer 1

avometer?
Ampere Meters has low internal resistance and is placed in series with circuit to measure current
Volt Meters has high internal resistance and is placed in parallel of a circuit to measure the Voltage across it.
Of course the meters internal resistance are considered relative to circuit's.

Answer 2

i mean this

Answer 3

Go to site given, then translate to English, you'll find out it's a Multi - Volt - Amp - Ohm meter. Use there specification for internal resistances and maximum Volts or Amps

Answer 4

An ammeter is a measuring instrument used to measure the electric current in a circuit. Electric currents are measured in amperes (A), hence the name. Instruments used to measure smaller currents, in the milliampere or microampere range, are designated as milliammeters or microammeters. Early ammeters were laboratory instruments which relied on the Earth's magnetic field for operation. By the late 19th century, improved instruments were designed which could be mounted in any position and allowed accurate measurements in electric power systems.
