Current Measurement In Μa And Ma Ranges - VOLTCRAFT VC1008 Anleitung

i) Current measurement in µA and mA ranges
Currents of up to 4000 µA can be measured in the µA measuring range and up to 400 mA in the mA
measuring range. Both measuring ranges are provided with fuses and thus protected against overload.
In the AC range, the current is measured as a true RMS value. You can switch to "AC+DC-coupled True
RMS" by pressing the yellow push button.
Proceed as follows to measure µA and mA currents:
°C
10 A MAX HzV
µAmA% COM
• For AC measurements, the measured value is shown on the main display (12). The frequency of the
alternating current is shown on the right subdisplay, and the active measuring range is shown on the
left subdisplay.
Never measure currents that are higher than 400 mA in the mA/µA range because this
triggers the miniature fuse.

• Connect the black test lead to the COM jack and the red test lead to the
mA/µA jack.
• To measure currents of up to 4000 µA, set the range selector switch (5) to
"µA"; set it to "mA" for currents of max. 400 mA. After the measuring range
has been selected via the range selector switch (5), DC measurement is
automatically activated.
• Now connect the two probe tips in series with the measurement object
(battery, circuit, etc.); the respective polarity of the measured value and
the measured value are shown on the main display (12). The active
measuring range is shown on the left subdisplay.
• For AC measurements, press the blue button once. "AC True RMS"
appears on the display (1).
