6.3 Functions
52
Measurement voltage
Function Sets the measurement voltage.
Default state 1.0 V
Setup ranges 0.1 to 1000.0 V (0.1 V resolution)
Fixture capacitance open correction function
Function Measures the capacitance with the fixture in the open state (fixture capacitance).
*This function must be executed before using the contact check function.
Default state OFF
Contact-check
Function Judges the contact state by comparing the measured capacitance to a reference value.
Method Capacitance measurement using a high-frequency signal
Default state OFF
Setups OFF / ON
Target object capacitance
setting range
0.5 pF to 99.9 pF (0.1 pF resolution)
Capacitance measurement
range
(Fixture capac target object capacitance) = 0.5 pF to 99.9 pF (0.1 pF resolution)
*However, the target object capacitance must be greater than or equal to 1/10 of the
fixture capacitance.
*With a 1 m measurement cable.
Judgment GO : Capacitance measured value > judgment reference value*
NG : Judgment reference value*
≥
capacitance measured value
*Judgment reference value = Fixture capac (target object capacitance setting / 2)
Execution conditions Fixture capacitance open correction must have been performed.
Capacitance measurement
accuracy
±(20% of r 0.2 pF)
*When using a measurement cable (1 m) and voltage output cable (1 m) after perform-
ing fixture capacitance open correction.
Measured value comparison and judgment function
Function Compares the measured value and reference value to make a PASS/FAIL judgment.
Default state OFF
Setups OFF / ON
Judgment HI : Measured value > upper limit setting
IN : Upper limit setting
≥
measured value
≥
lower limit setting
LO : Lower limit setting > measured value
Judgment reference value
setting range
-9.9999E+30 to 9.9999E+30
*The reference value is a current value if the display setting is current, or a resistance
value if the display setting is resistance.
