Error Correction
Measurement cables, probes, and fixtures have stray admittance and residual impedance. Since
these characteristics influence measured values, measurement accuracy can be increased by cor
-
recting for them.
First, set the measurement mode to LCR mode (p. 24).
Settings are configured on the
ADJ
screen.
Check the following before performing correction:
•
Turn on the instrument and allow it to warm up for at least 60 min. before performing correction.
•
The measurement accuracy values defined in the specifications are for when open circuit correction and
short circuit correction are performed. Before performing measurement, be sure to perform open correc
-
tion and short correction.
•
Be sure to repeat the correction process after changing measurement cables, probes, or fixtures. You will
be unable to obtain correct values if measurement is performed in the correction state prior to replace
-
ment.
•
When performing correction, make sure that there is no noise source nearby. Noise may cause an error
when performing correction.
ex. Servo Motor, switching power source, high-voltage cable and etc.
•
Perform correction under conditions that are similar to the environment in which the sample actually will be
measured.
•
The corrected value is preserved in the memory of the main instrument even when power is turned off.
•
Before performing correction, configure the low Z high accuracy mode, cable length, and DC bias settings.
Changing any of these settings will invalidate the correction values.
(See "Low Z High Accuracy Mode (high-precision measurement) (AC/DC)" (p. 56), "5.1 Setting the
Cable Length (Cable Length Correction)" (p. 98), and "DC bias (superimposing a DC voltage on the
measurement signal)(AC)" (p. 60).)
