Set Value Menu - Fluke 8508A User Manual

This menu defines four menu keys:
Indicates to the user that the calibration point is automatically set according
Auto
to the amplitude (and frequency in ACV) of the signal detected. Auto is the
default selection on entry to the
appearing later in this chapter for the calibration points for the selected range.
An indication of the use of the SAMPLE key is also displayed
The Set feature is available in all functions, allowing the user to enter the true
Set
value of the calibration standard where it differs from nominal calibration
point value. Pressing Set displays the
Frequency mode, when the
calibration reduces flatness errors within ± 10 % of the spot frequency. Set is
not available for DCV, DCI, and Resistance range zero calibrations.
Special Special Cal is indicated on the main display. The SPCL menu is displayed
which allows pre-calibration of the instrument, calibration of the frequency
counter, and entry to other calibration utilities.
Exits from the CALIBRATION menu via the CALIBRATION DUE ? menu,

where the recommended next calibration date can be entered, before finally
quitting the calibration mode.

SET VALUE Menu

This menu is obtained by pressing the Set key in the
functions except ACV Spot Frequency.
When this menu appears, it shows the nominal calibration point value, allowing the user
to enter the true output value of the calibration standard at the point to be calibrated. The
keyboard is activated, locking out all other keys. The Set value is entered in exponential
format expressed in Volts, Amps, or Ohms, and must be above 20 % of range (40 % on
the 1000 V DCV and ACV ranges). The
stored by pressing the Enter key.
The 8508A always chooses the most-recently stored Set value when calibrating.
not available for DCV, DCI, and Resistance range zero calibrations.
Enter: The new value is stored and the keyboard is de-activated. The
set value remains on the dot-matrix display for comparison with the
reading on the main display after the SAMPLE key has been pressed.
Quit: Reverts to the CALIBRATION menu, deleting the set value from
store.
