3.
Configure the Model 2430 ohms function for the 4-wire sense mode as follows:
•
Press CONFIG then MEAS
Ω
. The instrument will display the following:
CONFIG OHMS
SOURCE SENSE-MODE GUARD

•
Select SENSE-MODE, then press ENTER. The following will be displayed:
SENSE-MODE
2-WIRE 4-WIRE
•
Select 4-WIRE, then press ENTER.
•
Press EXIT to return to normal display.
4.
Press MEAS
Ω
to select the ohms measurement function, and make sure the source out-
put is turned on.
5.
Verify ohms measurement accuracy for each of the resistance values listed in Table 1-7.
For each measurement:
•
Set the resistance calibrator output to the nominal resistance or closest available
value.
NOTE
It may not be possible to set the resistance calibrator to the specified value. Use the
closest possible setting, and modify reading limits accordingly.
•
Select the appropriate ohms measurement range with the RANGE keys.
•
Verify that the Model 2430 resistance reading is within the limits given in the table.
6.
Repeat the entire procedure using the rear panel INPUT/OUTPUT and 4-WIRE SENSE
jacks. Be sure to select the rear panel jacks with the front panel TERMINALS key.

1. Nominal resistance values.
2. Reading limits based on Model 2430 normal accuracy specifications and nominal resistance values. If actual
resistance values differ from nominal values shown, recalculate reading limits using actual calibrator resistance
values and Model 2430 normal accuracy specifications. See Verification limits earlier in this section for details.
