Tegam 3550 - Correction Frequency Limit Setting Mode

4-16
Model 3550 LCR Meter Instruction Manual Operating Instructions
Front Panel Description cont’d:
[SHIFT] ĺ [-]: Correction Frequency Limit Setting Mode
As an alternative to zero correcting the entire frequency range 42Hz~5MHz, this function
allows the user to set the correction frequency range in terms of upper and lower limits.
Press [SHIFT] ĺ [-] to enter the Correction Frequency Setting Mode. The “BIN” LED will be
flashing. Press either [1] to edit the low limit correction frequency or [2] to edit the high
limit correction frequency.
Use the [CURSOR Ź] or [CURSOR Ż] keys to navigate between the “BIN” LED, DISPLAY C
Digits, Decimal Point and Frequency Units. To change the frequency value indicated on
DISPLAY C, simply press the [0]~[9] keys.
Press the [DP] key to change the position of the decimal point and use the [UNIT] key to
select Hz, kHz, or MHz units.
Press the [ENTER] key in order to finalize the new setting and to return to measurement
mode.
NOTE: While in the Spot Correction Frequency Mode, the Spot Correction Frequency high or
low limit setting can be enabled or disabled. This is done by pressing the [IGNORE] key.
[SHIFT] ĺ [OPEN]: Spot Correction Mode (Open Correction)
The spot correction Mode is used for making open and short-circuit frequency corrections.
Pressing the [SHIFT] ĺ [OPEN] keys will allow an open circuit, spot frequency correction to
take place. The open circuit correction is performed only on the three spot frequencies that
are defined by pressing [SHIFT] ĺ [8], (see Defining Spot-Correction Frequencies for Zero
Adjustments).
Note that Spot Frequency Zero Corrections have precedence over Normal Zero Corrections.
This means that the open and closed-circuit, zero correction factors for the spot frequencies
will be stored and retained in the instrument’s memory and will be written over unless an
additional spot frequency correction procedure is performed. Performing a standard zero
correction procedure will write over the zero adjustment factors of all test frequencies
except the three user-defined, spot correction frequencies.
[SHIFT] ĺ [SHORT]: Spot Correction Mode (Short Correction)
Pressing [SHIFT] ĺ [SHORT] initiates the Short-Circuit, Spot Frequency Correction
process. The offset adjustment affects only the three user-defined Spot Correction
Frequencies discussed in the, Defining Spot-Correction Frequencies for Zero Adjustments
section ([SHIFT] ĺ [8]).
Like the Open Circuit Spot Frequency Correction Mode, Short Circuit Spot Corrections have
precedence over Normal Short Circuit Zero Corrections. Closed circuit, spot correction
factors will be stored and retained in the instrument’s memory and cannot be written over
unless an additional spot frequency correction procedure is performed. Performing a
standard zero correction procedure will write over the zero adjustment factors of all test
frequencies except the three user-defined, spot correction frequencies.
