To clear the history of the logbook (Fig. 28):
1. In any of the logbook history displays, PRESS the [Select] button and hold in for 2 seconds. Located in
Field 1 is the text “CLR”; in Field 2 the text “HIS”; and in Field 3, “nO” will begin to flash.

The logbook history is erased and a new starting date is set to begin new cumulative measurements.
Note: If the user does not press any button for 1 minute in the setup mode, the display will automatically
exit setup.
We recommend that the logbook history be cleared prior to beginning logbook recording(s).
CHAPTER 4 BAROMETER MODE
The Barometer mode provides the user with:
• an adjustable unit of measure mbar or inHg; mbar range 300 to 1 100 mbar, inHg range 8.90 to 32.40;
• a resolution of 1 mbar or 0.05 inHg;
• a one hour interval measuring to estimate barometric trend;
• an automatic 4-day memory of atmospheric pressure for the last 6 hours in 1-hour intervals, thereafter, in 6-
hour intervals;
• temperature compensation (temperature does not effect the pressure within the specified temperature
range)
• a temperature range -20
O
to 60
O
C or -5
O
to 140
O
F; and
• a temperature resolution of 1
O
C or F.
Note: Body heat will effect temperature when the Wristop Computer is worn on the wrist. To achieve an
accurate reading remove the Wristop Computer from the wrist and allow at least 15 minutes before reading
the temperature.
If you’ve been in the barometric mode for more than 15 minutes with no rate of vertical movement, you should
