Operating precautions given throughout the text should be carefully ob- served. Options Test Frequency FOl Front panel BIAS indicator lamp will illuminate. The ImV step minimum voltage control as well as the accu- rate voltage setting capability of 0. A de- fective display can be isolated by the test described immediately below.

The stored memory of the con- trol settings is continuously held in event the. Set A manaul according to Gen- eral Component Measurement procedure Figure steps 7 through The A may exhibit the following phenomena: Bias voltage settling time is short. Thus, these accuracy graphs show different curves for lower and higher measurement values. Measured Values and Behavior of Components.

Test Fixture, cable con- nection type, 4-terminal pair, useable with dc biases up to volts. Almost all discrete circuit components inductors, capacitors or resistors except for components having special shapes or di- mensions can be measured with this setup. For Phenomenon -1 – 1: Note The equipment required for these sample programs include: Equations in table represent: Depend- ency of the dissipation factor quality factor upon test frequency offers a theoret- ical basis for such inference.

Disconnect external DC bias from A. Additionally, a fuse HP Part No. The three numeral combinations in the tables indicate the numbers of digits displayed in the respective range and test fre- quency areas. Figure outlines the setups and operating procedures for the Self Test. Inductance and resistance offset ad- justments are automatically performed. This method, however, cannot be used for inductance measurements on DUTs of from nH to 3yH when the test frequency is a special option frequency from 4MHz to Two extra frequencies are also optionally available along with Op- tion Approximately 8 times the normal measurement time.

If the serial prefix or number of an instrument is lower than that on the title page of this manual, see Section VI! This automatically sets instrument to L-ESR measurement mode. Usually, a series measurement circuit is employed for the measurement of a low impedance sample and a parallel measurement circuit for a sample of high impedance.

ZERO offset adjustment with a test fixture whose useable frequency range is no as broad as the instrument’s – e. Front Panel Features Sheet 1 of 4. D and Q ranges.

External DC Bias Circuits. When you push the button, the pushbutton lamp lights and the diagnostic test is initiated. Replace top cover and reinstall power cable. A total of 10 test signal frequencies which have a frequency accuracy of 0.

The lamp automatically lights when an Impedance measurement function is set. Turns instrument on and readies instrument for meas- urement. Relationship of Magnetization and Inherent Inductance.

Measurement Accuracies sheet 3 of 9. This continuous memory capability enables the instrument to preserve the memory of the de- sired front panel control settings and to re- call these settings for repeated selection of the same settings anytime and every time the instrument is turned on.
