3.2 Setting Measurement Conditions
18
This section describes how to set measurement conditions according to the
manner in which the instrument is to be used. Settings are configured via either
of the instrument’s external interfaces:
See:
GP-IB/RS-232C Interface (p.19)
The instrument cannot be configured directly in a standalone manner. For more
detailed setting specifications, see "6.3 Functions" (p.51).

information
Measurement
value indication
Selects the displayed value.
[Resistance * / Current]
* Resistance is calculated from the set measurement voltage and current
value.
Measurement
speed
Selects the measurement speed.
[FAST / MED (medium) / SLOW / SLOW2]
Current
measurement
range
Switches the current measurement range.
[HOLD/ AUTO]
Selects the current measurement range.
[100 pA/ 1 nA/ 10 nA/ 100 nA/ 1

A/ 10
μ
A/ 100
μ
A/ 1 mA]
Trigger delay
time
Fix time between inputting trigger signal and starting measurement.
0 ms to 9999 ms (1 ms resolution)
Averaging
Configures averaging of measured values.
OFF (No averaging) / ON (Required setting number of times for averag-
ing) / AUTO (Number of times for averaging is automatically determined)]
Number of times (in case “ON” setting): 1 to 255
Power source
frequency
Selects the power source frequency.
[50/60 Hz]
Measurement
voltage
Sets the measurement voltage.
Setup ranges: 0.1 to 1000.0 V (0.1 V resolution)
Fixture capaci-
tance open cor-
rection function
Measures the capacitance value with the fixture in the open state.
The fixture capacitance open correction function can be used to increase
measurement precision by decreasing the effects of residual inductance of
the fixture (including probes) and other components.
Contact-check
Judges whether the object under measurement is connected by perform-
ing capacitance measurement with a high-frequency signal and evaluating
the difference between that reading and the reading obtained when the
system is in the open state.
[OFF/ ON]
Judgment GO: Capacitance measured value > judgment reference value *
NG: Judgment reference value *
≥
capacitance measured value
* Judgment reference value = Fixture capac (object under mea-
surement capacitance setting / 2)
Measured value
comparison/
judgment func-
tion
Compares the measured value and reference value to make a PASS/FAIL
judgment.
[OFF/ ON]
Judgment HI : Measured value > upper limit setting
IN : Upper limit setting
≥
measured value
≥
lower limit setting
LO: Lower limit setting > measured value
Fixture resis-
tance open cor-
rection function
Measures the current of the fixture in the open state and corrects mea-
sured values.
[OFF/ ON]
LCD display
mode
Turns the LCD display on and off.
[OFF/ ON]
