1. Connect the red test lead to the Cx+ input and the black test
lead to the Cx– input.
2. Set the function/range switch to the capacitance range that
gives the best resolution.
3. Apply probe tips to the capacitor leads. When measuring
electrolytic capacitors, observe correct polarity.
4. Read the capacitance value on the display (you may have
to wait a few seconds until the capacitor is fully charged). If
“OL” appears in the highest range, the capacitor is too large
to be measured.
Note: For small value measurements utilize CAP Zero Adjust to
eliminate test lead capacitance (±20pF).
Note: Small value capacitors can also be measured by inserting
their leads directly into the slots in the meter.
Safety Test Leads
The test leads included with your meter have shrouded
banana plugs to eliminate the possibility of shock if the plugs
accidentally pull out of the meter while making a measurement.
Always inspect the test leads for damage before making any
measurements.
