Measuring Capacitance
Measuring Temperature
Disconnect circuit power and discharge all high-voltage capacitors before measuring 
capacitance to prevent possible damage to the multimeter or the device under test. To 
confirm that capacitors have discharged, use the DC voltage function.
Measuring tips: 
• For measuring capacitances greater 
than 10,000 µF, discharge the 
capacitor and manually select a 
suitable measurement range. This will 
speed up measuring time in order to 
obtain the correct capacitance value.
• Ensure the correct polarity when 
measuring polarized capacitors.
• For measuring small capacitances, 
press   with the test leads open 
to subtract the residual capacitance of 
the multimeter and leads.
• Do not bend the thermocouple leads at sharp angles. Repeated bending over a 
period of time can break leads.
• Do not contact the temperature sensor to any surface that is energized voltage or 
current sources, such the voltage source will pose a shock hazard.
