Toggle the Gage sounds ON (checked) or OFF (unchecked).
Flip Display
This option causes the display to rotate 180°. Ideal for right-side-
up viewing when the sensors are pointed away from the user.
NOTE: DPM-A models automatically rotate when the instrument
is reorientated .
Backlight
Selects display brightness (Sun, Normal or Night). All settings will
dim slightly after a period of no activity to conserve battery life.
Press the Down button to brighten the display.
Set Clock
All batches are date-stamped when created, and all datasets are
time-stamped (24 hour format) when stored into memory. It is
therefore important to keep both the date and time current using
this menu option. Use the Up and Down buttons to scroll, and the
(-) and (+) buttons to adjust a value. The Gage's date and time
can also be viewed in Gage Info (pg. 12).
Battery Type
Selects the type of batteries used in the Gage from a choice of
"Alkaline",
rechargeable). If NiMH is selected, the Gage will trickle charge the
batteries while connected via USB to a PC or optional AC charger.
The battery state indicator icon is calibrated for the selected
battery type. No damage will occur if the wrong battery type is
selected.
NOTE:
DeFelsko recommends the use of eneloop (NiMH)
rechargeable batteries. It may take as long as 12 hours to charge
dead batteries.
