MicroTim XB is DESCENDING at an
average rate of 1150 units per minute.
where ‘units’ are feet by default, but may be set to meters by changing the units (see section 7.2.1).
7.2.1 VSI Units
The unit selections available in altimeter mode are also available in vsi mode. The default is feet per minute. You
may toggle to metric (meters per minute) by holding the key for 5 seconds then releasing.
7.2.2 VSI Deadband
MicroTim XB will display as zero any climb/sink rate less than 30 feet per minute.
7.3 Exiting VSI Mode
Normal altimeter operation is restored by executing a NORMAL system reset (by initiating a reset and NOT
touching any keys until it is complete. See section 1.3, Restoring Factory Default Settings.
8 Vertical Accumulator Mode
MicroTim XB is primarily for altitude indication. However, it can also be configured to act as a vertical
accumulator. This logs the total vertical distances traversed by the unit since last zeroed. Like barometer and vsi
modes, accumulator mode is activated by executing a special system reset.
8.1 Activating Accumulator Mode
To activate accumulator-mode:
5) Begin a system reset by holding down the key for 5 seconds then releasing the key. The system reset
will begin when the key is released. During the reset MicroTim XB will show the serial number ‘sern’ and
firmware revision number ‘frn’ followed by a screen test starting with ‘0000’ and ending with ‘9999’.
6) At any time during the screen test (before ‘9999’ appears) press and hold the key. If this key is being
HELD DOWN as the reset cycle completes (i.e. showing 9999 on the screen) then MicroTim XB will enter
accumulator-mode. Do not release the key until ‘ACC’ appears on the display. MicroTim XB is now in
accumulator-mode and you may release the key.
8.2 Using the Vertical Accumulator
In accumulator-mode, MicroTim XB displays 3 distances in a cyclic fashion, all in TENS of units (feet or meters):
