Preparation for Use
In This Chapter
Before turning the 4338B ON, you must rst set the 4338B to match the available power LINE
voltage
.
If the 4338B's power LINE voltage and frequency are properly set and ready to use
,you can
skip this chapter
.

4338B
To Set P
ower LINE Frequency
1. Connect the power cable to the power cord receptacle on the rear panel.
2. Push the LINE switch in. The 4338B will emit a beep when it turns ON, and perform
the self test. (If any message is displayed, see \Error Messages" back of
4338B Operation
Manual
.) The 4338B will be ready for operation after amessage like the following is
displayed.
3. Press .The following message is displayed.
4. Press until \
Line "blinks
,and press .
Ablinking item means that it is currently selected.
5. If the setting does not match the power LINE frequency
,press to toggle the setting
between \
50 Hz
"and \

", then press .
6. Press until
Exit blinks
,andpress .
Note
The power line frequency setting is stored and is not changed after reset or
power-o. Once you set it, you do not need to set the line frequency again as
long as the same power line frequency is being used.

Operating the 4338B
In This Chapter
Basic measurement operations of the 4338B and references are explained.
F
or measurement, we use the 16338A Test Lead Set with the 4338B.
Operating the 4338B 2-1

4338B
Let's Try|Fully Automatic Measurement
The 4338B's auto measurement function automatically selects the appropriate test signal
level and measurement range
.Y
ou can measure the DUT with very simple procedure, only
connecting test leads
,performing aSHORT correction, and connecting the DUT
.
Resetting 4338B to its Default Settings
1. Press to select the reset menu.
2. Press until
Yes
blinks, and press .
The 4338B will be reset to its default settings
.F
or more information about the default settings
,
see \Default Settings" later in this chapter
.
Note
When the
A
uto Measurement indicator
turns ON, the auto measurement
function is active
.
Resetting the 4338B,or pressing
activates the auto measurement function.
Connecting the T
est Leads
Connect the test leads to the UNKNOWN terminals as follows:

P
erforming a SHORT Correction
|Canceling the residual impedance in series with the DUT
1. Congure the test electrodes in a SHORT conguration by connecting the High and Low
electrodes to each other. (For information on the SHORT conguration, see \SHORT
Conguration
"on page 2-13.)
2. Press .The SHORT correction menu is displayed.
3. Select
ShortMeas
using or , and press .The SHORT correction is performed
with the following message
.
After awhile
,the 4338B will display the SHORT correction nished message,
and return to the measurement mode
.
If \
WARNING: Out Of Limit
"is displayed
The SHORT impedance is so high that it would be unsuitable for SHORT correction data.
If \
WARNING: Improper Correction
"is displayed
When the \
OVLD ", \
OVVOL
"or \
N.C.
"is displayed during the SHORT correction.
Check that the test leads are properly connected to the UNKNOWN terminals
.
Check that the test clips are properly shorted.
And then perform the SHORT correction again.
Operating the 4338B 2-3

4338B
Measuring aDUT
Connect the DUT to the test leads
,and the measurement result will be displayed.
T
est Voltage Limit
The peak voltage across the DUT does not exceed 20 mV.(When the test voltage exceeding
20 mV, the 4338B disables the test voltage output and displays \
OVVOL
"(Over V
oltage).) It
prevents the test voltage from destroying the oxidation lm, formed between the contacts
.So
,
even when an unknown DUT is measured without special preparation, the contact resistance is
still accurately measured without disturbing the state of the oxidation lm.
T
oSet T
