Chapter 5 ANALYZER Function
• The guaranteed accuracy range varies depending on the measurement conditions.
See: Check the guaranteed accuracy range in "13.2 Measurement Range and Accuracy" (p. 395).
• The measurement range is determined according to the test range setting.If the display
for the measured value shows "OVER FLOW" or "UNDER FLOW", that means that mea-
surement cannot be performed using the currently set test range. Either you should set
AUTO ranging so as to select the most suitable test range automatically, or you should set
a more suitable test range manually.
• If the measurement range setting exceeds the range in the table above when the mea-
surement frequency is set, it is automatically changed to the maximum setting. For exam-
ple, if the frequency is set to 1.001 MHz when the measurement range is in the 1 M
range state, the measurement range is changed to the 100 k range.
• If FREQ (frequency) is set for sweep (p. 143), some ranges cannot be used depending on
the frequency range.
•10 M range: Up to 1.0000 MHz
•100 M
range: Up to 100.00 kHz
• With a test sample whose impedance varies with frequency, if the frequency is changed
during measurement using HOLD, measurement within the same range may not be possi-
ble. When this happens, change the measurement range.
• 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 "7.1
Setting Open Circuit Compensation" (p. 273) and "7.2 Short Circuit Compensation" (p.
280).
