4300C Calibration Procedure
Standard Calibration
The standard calibration consists of three parts: sense calibration, source calibration and final adjustment.
The sense calibration and the final adjustment calibration is cover-on and automated; the instrument will
prompt the user throughout the steps. The source calibration is performed by adjusting six
potentiometers located on the 4300C main board. All three calibrations must be performed for a complete
calibration of the 4300C.
Sense Calibration
I.
Press the
“F

”
.
II.
Press
“C

”
to choose the standard calibration.
III.
Apply a short between the Sense Hi and the Sense Lo
binding post. Once the short is applied, press
“E
NTER
”
. The
ohmmeter will perform the zero calibration for all ranges.
Press
“C

”
to return to the previous screen.
While zeroing the ranges, the screen will display the
following information:
IV.
When prompted by the display, remove the short and apply
10mV to the sense terminals. Press
“E
NTER
”
to continue or
“C
LEAR
”
to return to the zero cal screen.
While calibrating the ranges, the screen will display the
following information.
Pass indicates the number of passing
values that have been measured.
15 passing values must be measured
before the timer reaches the 100
second limit for a successful calibration.
