2.5.5 Brightness
The BRIGHTNESS function changes the brightness level of the instrument’s front panel display.
Use the Up, Down, Left, or Right button to change the brightness to any one of four levels. Press ENT to save
the selected brightness level.
2.5.6 Clock
The CLOCK function sets the instrument’s date (MM/DD/YY) and time (24 hour format, where 1:00 PM is
displayed as 13:00). The clock allows measured values to be logged with a date/time stamp (refer to Section
4.2.9 Logging Measured Readings).
Use the Left and Right buttons to move the blinking cursor across the screen to highlight the digits to be
modified, and then use the Up and Down buttons to modify those digits. Press ENT to save the new date and
time values.
2.5.7 PCHK Mode
The PCHK Mode setting determines when the instrument performs an ambient pressure check as follows:
AUTO – A pressure check is performed once every 60 minutes.
AT CAL – A pressure check is performed at the end of every calibration.
Note that a pressure check is always performed when the instrument is first turned ON just before the warm-up
period begins, regardless of the PCHK Mode setting.
Use the Up and Down buttons to highlight the desired setting. Press ENT to save the selection.
2.5.8 Probe Button
The PROBE BUTTON function selects what action is performed by the pushbutton on the Standard Probe with
LED and Pushbutton.
DISABLED – No action performed.
MODE KEY – Toggles the instrument between its Search and Measure mode.
ENTER KEY – Performs the same function as the ENT / ZERO key on the instrument’s front panel.
Use the Up and Down buttons to highlight the desired setting. Press ENT to save the selection.
2.5.9 Reset Defaults
The RESET DEFAULTS function returns the instrument to its factory default settings per Appendix “A”.
This operation requires a three key press. Simultaneously press the ENTER+ESCAPE+VOL buttons to reset
defaults.
