Connect semiconductor device to test fixture. The correct dis- sipation factor is calculated by the follow- ing equation: A special biasing circuit using exter- nal voltage or current bias, as needed for capacitor or inductor measurements, is illus- trated in Figure DC Bias Connector This is especially useful in design or in other objectives where the data gathered should be done so under near-actual operating conditions. Self Test Basic Operating Check. If dc bias 1s not neces- sary, setup arrangement and procedures associated with this measurement may be deleted.

The A is set to be talker. These pushbuttons select primary component parameter to be measured as follows: These pushbuttons select test signal level variable ranges: Read A capacitance display after allowing time for bias volt- age to settle.

Three kinds of con- tact electrode modules are furnished same for the A Test Fixture. Set test signal for the desired ampli- tude. The power cable must either be plugged into an maunal three-contact electrical outlet used with a three-contact to two-contact adapter with the grounding wire green firmly connected to an electrical ground safety ground at the power outlet.

Internal dc bias operation without Internal bias supply installed.

It calls attention to a pro- cediire, practice, condition or the like, which, if not correctly performed or adhered to, could result in injury or death to personnel. Coifnnabit 7: The reference mznual is obtained and memorized from the preceding m.

The combination of these two parameter values is the vector impedance expression for the sample.

This connec- tor is used for externally triggering the instrument by inputting an exter- nal trigger signal. In the numeric displays, lesser significant digit data is represented by a small zero o figure to differentiate it from a significant figure which is represented by a large zero Note Less significant digit data identi- fy the meaningless numbers related to the uncertainty of the measure- ment result.

This program code can be used to recall a display A reference value, “LV”: For Phenomenon -1 – 2: The lamp automatically lights when an Impedance measurement function is set. Pageparagraph Intensity of magnetization magnetic flux density of a ferromagnetic core varies along and with its mag- netization characteristic curve B-H curve in response to the cyclic current flowing through the inductor coil.

These specifications are the per- formance standards or limits against which the instrument is tested. Error in ZERO offset adjustment.

If an abnormal result occurs during the open or short test, the number np the abnormal step is displayed in DIS- PLAY A as, for example, illustrated below: Remote Program Codes sheet 2 of 2. These units cover the lower and higher frequency re- gions, respectively — and both reflect the new concepts.

Manual ranging is also feasible. Front handle kit, for front handle installation. Operating precautions given throughout the text should be carefully ob- served. ZERO offset adjustment with a test fixture whose useable frequency range is no as broad as the instrument’s – e. Offset adjustment ranges are: These functions make possible the memorizing of a measured value as a reference value such that the subsequent display is the measurement minus the refer- ence value or the percentage that the meas- urement deviates from the reference.

Out put measurement data from the A may include two or more spaces in the first part of jp string, though each datastring should have only one space. Two hpp knobs facilitate and ensure optimum contact of electrodes and 4275aa leads. Auto Series and Parallel.

Test Clip Cable with spe- cial alligator clips, 4 tenni- nal. If the bias voltage across sample is not given sufficient time to settle, the displayed value may fluctuate or Err4 may be displayed.

The A and the power cord are furnished accessories. Measured L, C, R or jz value manusl too low compared to the selected range.

Typical Characteristics of Test Fixtures and Leads Place Cc5;0pF guard plate between comoonent leads of the samole and connect it to outer conductor of A-terminal pair as illustrated at left: Measurement Function The meanings of the option annunciations are outlined in paragraph General Information sheet 2 of 2. Measurement Ranges and Number of Display Digits sheet 2 of 5.

The Model A is equipped with a three-conductor power cable which, when plugged into an ap- propriate receptacle, grounds the instrument. Wrap instrument in heavy paper or plastic.
