Dc Current Measurement; Resistance Measurement - Velleman DVM835 Mode D'emploi

4. Read the voltage value and the polarity of the red test lead on the LCD
display.
Notes
 If the range is not known beforehand, set the selector switch to a high
range and lower gradually.
 An over-range is indicated by 1 or -1. Set to a higher range.

10.2 DC CURRENT MEASUREMENT

Do not measure circuits that may contain voltages > 500 VDC or
> 500 VAC
Use extreme caution when measuring voltages higher than 60 VDC
or 30 VAC rms.
Always place your fingers behind the protective edges of the test
probes while measuring!
1. Set the rotary switch in the desired "A=" position.
2. Connect the red test lead to the "VmA" jack and the black test lead to
the "COM" jack (switch the red lead to the "10A" jack for
measurements between 200 mA and 10 A).
3. Open the circuit in which the current is to be measured and connect
the test leads to the circuit IN SERIES.
4. Read the current value and the polarity of the red lead connection on
the LCD display.
Notes
 If the range is not known beforehand, set the selector switch to a high
range and lower gradually.
 An over-range is indicated by 1 or -1. Set to a higher range.
 The maximum input current is 200 mA.

10.3 RESISTANCE MEASUREMENT

Do not conduct resistance measurements on live circuits. Make sure
all capacitors in the circuit are depleted.
1. Set the rotary switch in the desired "Ω" position.
2. Connect the red test lead to the "VmA" jack and the black test lead to
the "COM" jack.
3. Connect the test leads to the resistor to be measured and read the
LCD display.
