Specifications are for 90 minutes warm–up and REL operation. Additional errors may be caused by non–film capacitors.
Specifications are for 1% to 110% of range on 2 nF range and 10% to 110% of range on all other ranges.
Measuring Characteristics
Capacitance Measurement
Measurement Method Apply constant current into the capacitance, and measure the voltage changing rate.
Connection Type 2-wire
Measurement Considerations
Since small capacitance measurements are susceptible to error caused by external noise, shielding inputs from external noise pickup is critical for minimizing
measurement errors.
