When editing any parameter, be sure to press the
ENT
button through the entire
line of alphanumeric characters to ensure that the edits are stored. Pressing any
button other than the
ENT
button advances to the next function without storing
the new value.
If a probe parameter is edited, the new parameter value is uploaded into the
INFO-CON probe connector when the CAL Mode is exited by pressing the
MODE
button or after scrolling through the menu and leaving the PDue pa-
rameter (see Section 7.9.16). The message "Uploading params" is displayed.
After the parameters have been uploaded into the INFO-CON probe connector,
the meter advances to the next menu item. Always check to ensure that the pa-
rameters have been written to the INFO-CON connector by disconnecting the
probe or by turning the instrument off and on and then rechecking the
parameters.
The calibration menu is entered by pressing and holding the MODE button for
three seconds. “CAL MODE” appears on the display. Press the ENT button to
advance. Press the MODE button while in the calibration menu to exit and to
advance to the display mode that follows the display mode that was active be-
fore the CAL Mode was entered.
The functions contained in the CAL Mode are listed below in the order they ap-
pear. In any of the functions, the
ENT
button stores the displayed value or se-
lection and advances to the next function. The
CLR
button can be used to
cancel changes to a value or selection and to skip to the next function.
Use the
ENT
button to move from Mtr Due to Prb Due and then to Time. Use
the
CLR
button to quickly advance through the remaining functions. Many of
the functions are in the passcode protected part of the CAL Mode. You must
enter the correct passcode to access those functions (see Section 7.9.4).
