Measuring Capacitance
Measuring Temperature
CAUTION
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.
CAUTION
– 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.
