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.
