Making Measurements
Auto Identification (Ai) function
Press to automatically identify the appropriate
measurement required for the device- under- test (DUT).
Figure 2-1 Using the Ai function
The annunciator will flash while the LCR meter
identifies the DUT, and
• selects an appropriate measurement in the primary
display (L, C, or R) and secondary display (D, Q, or θ),
• selects an appropriate range, and
• selects an appropriate measuring mode (series or
parallel).
The Ai function helps to identify L, C, and R measurements automatically
according to the angle of impedance detected in the DUT. See Table 2-1 for
the phase angle rules.
The default phase angle condition is set to 10°. You can change this angle
in the Setup menu from 5° to 45°. See “Changing the Ai function’s phase
angle condition” on page 63 for more information.
