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.
