Ac/Dc Voltage Measurement; Ac/Dc Current Measurement - Velleman DVM870 Notice D'emploi

6. Use
GENERAL
• When the range of the measured signal is unknown, start measurement
in auto-range mode, and then select range according to indicated value.
• The display shows "OL" when the present range limit is exceeded. Select
a higher range to continue measurement.
• Do not measure voltages > 600 V or current higher than 200mA
("VΩmA" jack [9]) or 10 A ("10A" jack [8]). Note that the meter can
only handle 10A for less than 15 seconds.
• The device will go in sleep mode when no activity is detected for ±15
seconds. Press any button to re-activate.

AC/DC VOLTAGE MEASUREMENT

• Connect the red test lead to the "VΩmA" jack [9] and the black lead to
the "COM" jack [7].
• Set the rotary switch [6] in the desired ACV or DCV (
position. If the voltage to be measured is unknown beforehand, set the
range switch in the highest range position and then reduce gradually until
the ideal resolution is obtained.
• When is selected, use the select button [3] to choose between AC
and DC voltage.
• Connect the test leads to the source being measured.
• Read the voltage value on the LCD display [1] along with the polarity of
the red lead connection.

AC/DC CURRENT MEASUREMENT

• Connect the red test lead to the "VΩmA" jack [9] and the black test lead
to the "COM" jack [7]. Connect the red lead to the "10A" jack [8] for
measurements between 200mA and 10A.
• Set the rotary switch [6] in the desired ACA or DCA (
use the select button [3] to choose between AC and DC current.
• Open the circuit in which the current is to be measured and connect the
test leads to the circuit IN SERIES.
• Read the current value and the polarity of the red lead connection on the
LCD display.
