Dc Current Measurement / A - Testboy TB-313 Instrucciones De Empleo

DC current measurement / A=

Use the selector switch to set the appropriate range. Connect the black test
lead into the "COM" socket, and the red test lead with the mA / 10A socket
(the appropriate socket opens automatically depending on the measuring
range). Using the test probes, touch the test points of the test object. Read
measurement value on the display. The current direction is indicated by the
sign.
You must use the '10 A' socket when measuring currents abo-
ve 200 mA.
