Measuring Capacitance - Extech Instruments MS420 User Manual

M C
EASURING APACITANCE
To measure Capacitance, refer to the following:
Insert the black lead into the COM jack, and the red lead into the V/Ω/C
1.
jack
2. Press the R key. An 'R' appears at the top of the screen
3. Press the SET key until the C appears at the top of the screen
4. Connect the black and red leads to the capacitor or circuit under test; the
meter will display the reading (Unit of measure: Farad)
Notes: To improve accuracy when the measured value is lower than 5 nF, select the
lowest capacitance range and use the Relative mode.
Please allow approx. 30 seconds for capacitance measurements larger than 40uF.
Refer to the example diagram in Figure 5.
