NOTE (10-12 pico Farad Farads) (10-9 nano Farad Farads) (10-° micro Farad Farads) (10-' milli Farad Farads) Accuracy is based on an operating temperature of 23°C (73°F) at relative humidity up to 75%. Test Voltage: >3.5 volts peak maximum, "+" input terminal voltage is always higher than"... -
Page 5: Useful Conversions
Very low capacitances should be measured by using extremely short leads in order to avoid introducing any stray capacitances When using the optional test leads, remember that the leads introduce a measurable capacitance. Capacitors, especially electrolytics, often have wide tolerances. The measured value may be greater than the value marked on the capacitor. -
Page 6: Calibration Procedure
Calibration Procedure Set the meter to the 200 pF range and adjust the zero capacitance knob until the display reads zero. 2. Connect a standard capacitor whose value is near a full scale reading ± 0.1 % on one of the higher ranges, and is known to have within accuracy. - Page 7 CX-920A Schematic Diagram !I " 00 00 00 ' 0000 - 6 -...
