4.2 Setting Basic Settings of Measurement Conditions
68
• In the case of a test sample whose impedance changes according to the frequency, when
testing is being performed with HOLD set, it may happen, when the frequency is changed
over, that measurement cannot be continued to be performed upon the same test range.
You should change the test range if this happens.
• The test range setting is made according to the combination of the impedances of the
sample being tested and the test cables. Therefore it can happen that testing is not possi-
ble, if the test range is held with HOLD only upon the basis of the impedance of the sam-
ple under test. If this happens, you should change the test range, making reference to "8.1
Setting Open Circuit Compensation" (p. 215) and "8.2 Short Circuit Compensation" (p. 224).
• When the measurement value is outside the guaranteed accuracy range, the following
icon appears at the top of the screen.
In this case, you should consider the following possible causes, and you should either
change the test conditions while checking the accuracy assured ranges "14.2 Measure-
ment Range and Accuracy" (p. 342), or you should consider the measured values as val-
ues for reference.
• Perhaps the test signal level is too low, increase the test signal level.
• If the current measurement range (during HOLD setting) is not appropriate, set again
in the AUTO range, or change the range by manual.
