6-8
NOTE: This operation DOES change the coefficients and voids the previous calibration,
both resistance and current. Upon completion the 6530 will have to verified across the
operation range.
-
Reference Section 4.9.2.1.3.
-
Connect the 100 MΩ reference resistor between the SOURCE and INPUT
terminals of the instrument.
-
Select the SOFCAL CALIBRATE MENU by pressing the
<Calibrate>
function
key when in the Sofcal Menu
-
Press the
<Ref Vals>
function key.
-
Press the
<Ref Res>
function key. 2844275
-
Press the
<Edit>
function key.
-
Using the numeric keys enter the value of the reference resistor and its serial
number
-
New values for variance, standard deviation and sample size criteria for the 1 V and
0.1 V thresholds may be entered using the numeric keypad ifs required (see Section
4.9.2.3.3)
-
Press the
<Ok>
key to accept/store the new values.
-
Press the
<Cal Date>
function key.
-
Press the
<Edit>
function key to edit/re-enter the new calibration date.
-
Press the
<Ok>
key to accept the new calibration date.
-
Press the
<PREVIOUS>
key to exit back to the Sofcal Calibrate Menu.
-
Press the
<PREVIOUS>
key to exit back to the Sofcal Calibrate Menu (top).
-
Press the
<Utilites>
function key.
-
Press the
<Thresh Cal.>
function key.
Note: Ensure that the 100 MΩ reference resistor is connected. Press the <Calc> key
to start the automatic capacitor calibration sequence.
Note: When the calibration sequence is complete the instrument will prompt with
the new calibration coefficient in the display window.
-
The automated calibration sequence will run each measurement until it has satisfied
variance and standard deviation requirements for the sample size of each test.
-
If the requirements have not been met within the maximum retries the test is
automatically stopped.
-
If the test completes fully then acceptable results have been achieved. Press the
<Save>
key to save the results. This will update all threshold coefficients.
-
If the results are not acceptable then, you will need to return to the
<Reference>
Menu and adjust the test criteria to allow either more retries or a wider standard
deviation/variance for the failed test.
-
Press the
<PREVIOUS>
key to exit to the Sofcal Calibrate Menu.
