AUTO CALIBRATION
The Auto Calibration routine is a built in process in the 6530 that will calibrate all three
capacitor and both threshold values with a single 100 MΩ traceable resistor. This process is an
automatic sequencing of the Capacitor and Threshold Calibration routines which can be executed
on an individual basis as described in Sections 6.2.6 and 6.2.7. To execute this process follow
the steps below.
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 4.9.2.1.1.
-
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.
-
Press the
<Edit>
function key.
-
Using the numeric keys enter the new value of the reference resistor and its serial
number
