Before Calibrate the Barometer

- The K2-100 was calibrated for you in the factory. For normal

use, you need not to calibrate the Barometer. But for vigorous

users, a calibration procedure has been build in the K2-100.

- Before calibrate the Barometer, you must have the

ambient barometric pressure, because that pressure value

has to be input into the K2-100 during the calibration

procedure.

- You may call up the observatory station at the nearest

location from your current position to get the ambient

barometric pressure.

Important: Inputing an incorrect pressure in the calibration

procedure will result in a mistaken pressure reading in the future.

Pressure Calibration Procedures

- Press and hold the [adjust] button for 2 seconds to change

the display from the Pressure Graph Display to Barometric

Pressure Calibration Display.

- The digits of the middle row of the display and the barometric

pressure unit start flashing because it is selected.

- Press the [start/stop] button to increase the number; press

the [lap/reset] button to decrease the number. Hold down the

button to change the number at a higher speed.

- If you select a wrong barometric pressure unintentionally,

press and hold the [adjust] button for 3 seconds to restore

the setting to the absolute pressure value.

- After you set the barometric pressure, press the [mode]

button to exit the setting and return to Barometric Pressure

Graph Display.

- If no button is pressed in the setting display for about 3

minutes, the K2-100 will return to the Barometric Pressure

Graph Display.

6.5 Barometer Mode - 48 Hour Memory

48 Hour Memory

- The K2-100 has a built-in memory function: the 48

Hour Memory.

- 48 Hour Memory records the Barometric Pressure for

every one hour of the last 48 hours.

- These memories can be reviewed in the 48 Hour Memory

Display.

Review the 48 Hour Memory

- Press the [adjust] button to select the 48 Hour Memory

Display in the Barometric Pressure Graph Display.

- The 'BAROMETER 48 HR MEM' will slide out and display

for 3 seconds, the 'MEM' indicator will be shown also.

- The Barometric Pressure 48 hour history graph shows

on the 1st row of the display.

- The pressure memory and temperature show on

the 2nd row of the display.

- The time which recorded the memory shows on the 3rd

row of the display.

- Press the [lap/reset] button to view the memory through

backward scrolling (from -1 to -48 hour), press the

[start/stop] button to view the memory through forward

scrolling ( from -48 to -1 hour).

NOTE:

- The memory columns on the left hand side of the

history graph are recorded earlier than those on the right.

6.6 Barometer Mode - Ascending / Descending Rate of the 48 Hour Memory

Ascending and Descending Rate

- The K2-100 a has built-in a function for calculating the

ascending and descending rate of the Barometric

Pressure of the last 48 hours.

- These figures can be reviewed in the Ascending Rate

Display and the Descending Rate Display.

Review the Ascending and Descending Rate

- Press the [adjust] button three times to select the

Ascending / Descending Rate Display in the Barometric

Pressure Graph Display.

- While the Ascending / Descending Rate Display is shown,

the Barometric Pressure Ascending or Descending Rate

shows on the 1st row of the display.

- A (+) value implies ascending rate; a (-) value implies a

descending rate.

- The pressure memory and the temperature sho w on the

2nd row of the display.

- The time which this memory was recorded shows on the

3rd row of the display.

- Press the [lap/reset] button to view the memory by

backward scrolling ( from -1 to 48 hour), press the

[start/stop] button to view the memory through forward

scrolling (from -48 to -1 hour).

- While these displays are shown, press the [mode] button

to exit the reviewing and the display will return

to the Barometric Pressure Graph Display.

Implication of the Pressure History Graph

- In general, a rise trend in the Pressure History Graph

may forecast good weat

her ahead.

- A steady trend in the Pressure History Graph has the

possibility to have steady weather ahead.

- A falling trend in the Pressure History Graph may

predict bad weather ahead.

IMPORTANT: To get an

accurate result of the weat

her

forecast, the user has to stay at the same altitude for over

48 hours.
