Monarch 110 DC Voltage Measurements, AC/DC Current Measurements, Resistance Measurements

MODEL 110 AUTORANGING DIGITAL MULTIMETER

5.2 DC Voltage Measurements

WARNING

Maximum Input Voltage is 600VDC. To avoid electrical shock hazard and/or damage to this instrument, do not attempt to make any voltage measurement that may exceed this limit.

1. Connect the red test lead to the ‘V’ jack and the black test lead to the ‘COM’ jack.

2. Set the Function Selector switch to the V range.

3. Connect the test leads in parallel with the circuit being measured.

4. Read the measured voltage on the instrument display.

5.3 AC/DC Current Measurements

WARNING

To avoid injury, do not attempt a current measurement if the open circuit voltage exceeds the rated voltage of the meter.

1.If the current to be measured is unknown, connect the red test lead to the ‘A’ jack. If it is known or has been determined that the current is 400mA or less, connect the red lead to the ‘µA/mA’ jack. Connect the black test lead to the ‘COM’ jack.

2.Set the Function Selector switch to the current range corresponding to the jack being used and press the blue button to select AC or DC.

3.Remove power from the circuit to be measured and connect the instrument in series with this circuit. Connect the black lead to the negative (-) side and the red lead on the positive (+) side being measured.

4.Apply power to the circuit and read the measured current on the instrument display.
