Calibration Adjustment
The Product features closed-case calibration adjustment and uses known
reference sources. The Product measures the applied reference source,
calculates correction factors, and stores the correction factors in nonvolatile
memory.
Should the Product fail any of the performance tests, do the calibration
adjustment procedure.
When “C-01” is shown on the display, apply the correct input signal shown in
Table 4 to the Product. Then push to confirm the calibration step. If the input
signal does not satisfy the calibration requirement, “Err” is shown. If the signal is
not stable, it can be necessary to push several times to confirm the calibration.
After confirmation, the Product goes to the subsequent calibration step.
Note
After you push , wait until the calibration step number advances
before you change the calibrator source. Some adjustment steps
can take several seconds to execute before the Product goes to the
subsequent step.
Set the Calibrator to Standby after you complete adjustment of each
function.
Input each signal to the Product in the sequence shown in Table 4. When the last
calibration point is recorded, “End” shows on the display.
Note
While the calibration adjustment points are shown in Table 4, the
Product also can show the necessary inputs. For each step, push
to see the necessary current input and then push to see the
necessary frequency input.
