BASIC MEASUREMENT

PPM will be displayed on the right hand side of

the screen, next to mode.

Set constant voltage source

Background

If a DUT needs to be tested at a set voltage, the

constant voltage function can be used. Using the

C.V. function the LCR will maintain a source

resistance of 25Ω. Therefore the test voltage is

constant for any DUT impedance greater than 25Ω.

Using the constant voltage feature will reduce the

accuracy of measurements by a factor of 3.

Panel operation

1. Press 1/C.V to turn constant

voltage on or off.

C.V ON / OFF is toggled each time the 1/C.V

button is pressed.

Set Range hold

Background

When DUTs are disconnected from the test

cables/fixtures during continuous testing, Range

Hold can be used to avoid range switching. This is

particularly useful for repetitively testing a

number of DUTs. For more information on Range

and range hold, see the specifications, page 136.

Panel operation

1. Press 0/R.H to turn Range Hold on

or off.

R.H ON / OFF is toggled each time the 0/R.H

button is pressed.

Set Average

Background

An arbitrary number of tests can be averaged to

produce an averaged test result. 1-255 tests can be

averaged. The larger the number of tests that are

averaged, the longer the test time.

Panel operation

1. From the main menu, press MENU, followed

by SETTING and AVGE.

2. Enter the number of number of averages (tests)

using the numerical keys, and then press

ENTER.
