Measuring Ac Voltage; Measuring Dc Current - Velleman DVM860BL Manual De Instrucciones

REMARKS
• The LCD displays the overrange indication "OL" if the measured value is too high for the range you are using.
Select a higher range.
• Place the range selector in the highest position if the value to be measured is unknown beforehand.
• When measuring low voltage values, the display will show fluctuating values as the test leads approach the circuit
to be tested. Simply ignore these readings as this interference will disappear as soon as the test leads are
physically touching the circuit you want to test.

6.9. Measuring AC Voltage

WARNING
The input voltage should not exceed 600Vrms AC. Be very careful and avoid electroshocks when working with high
voltages.
1. Connect the black test lead with the COM jack and the red test lead with the INPUT jack.
2. Put the range switch in the desired V-range position.
3. Press the FUNC. button to select AC measurement. Select manual or auto range selection with the RANGE button.
4. Connect the test leads with the source or load under measurement.
5. Read the measured value from the LCD.

6.10. Measuring DC Current

WARNING
Deactivate the circuit to be tested before connecting it to the meter.
1. Connect the black test lead with the COM jack and the red test lead with the INPUT jack for current
measurements up to 200mA. Move the red lead to the 10A jack for measurements up to 10A.
2. Select the desired µ A, mA or A range with the range selector.
3. Press the FUNC. button to select DC measurement. Select manual or auto range selection with the RANGE
button.
4. Connect the test leads in series with the load under measurement.
5. The measured value and the polarity of the red connection are displayed.
REMARKS
• The LCD displays the overrange indication "OL" if the measured value is too high for the range you are using.
Select a higher range.
• Place the range selector in the highest position if the value to be measured is unknown beforehand.
• Respect the limit values
exceeded. The max. current for the 10A socket is 10A and this range is not fuse-protected.
DVM860BL
: the max. current for the INPUT jack is 200mA. The fuse will blow if the limit value is
