History Graph Scale Display
Barometric Pressure Graph Display
- In the Barometric Pressure Graph Display, the 1st row of
the display shows the pressure history graph of the last
48 hours.
T h e 2 n d r o w o f t h e d i s p l a y s h o w s t h e B a r o m e t r i c
Pressure and the current temperature.
- The 3rd row of the display shows the current time: hour
minute and second.

-
The Barometric Pressure history graph of the Barometric
Graph Display is plotted on these pressure values.
- The X-axis of the history graph is time variable; the Y-
axis of the history graph is barometric pressure variable.
The Barometric Pressure History Graph is made up
of 11 rows and 40 columns.
- T h e m e m o r y c o l u m n s o n t h e l e f t h a n d s i d e o f t h e
history graph are recorded earlier than those on the right.
- The scale of the history graph is changeable, the scale
will be changed in order to fit in the Barometric Pressure
values. Check the 'Barometric Pressure History Graph
Scale' section for more detail on the scale of the history
graph.
To Switch among Units
- The K2-100 can display pressure in millibar (mb) hecto
p a s c a l ( h P a ) o r i n c h m e r c u r y ( i n H g ) ; t h e K 2 - 1 0 0
can display temperature in Celsius ( C) or Fahrenheit ( F).
- Press and hold the [lap/reset] button to change the units
as in the units select sequence.

Pressure History Graph Scale
- T h e s c a l e o f t h e Y - a x i s o f t h e H i s t o r y G r a p h i s
changeable for fitting all t he pressure memory into the
graph.
- Press the [lap/reset] button once to view t he pressure
scale information, in the Barometric Pressure Graph
Display,
- The 'GRAPH SCALE' message will slide out and display
for 3 seconds, then the X-axis and Y-axis resolutions
will be shown.
- For example, 'X=1:00'00"' implies that the resolution of
X-axis is 1 hour per column; at the same time, 'Y=0.5mb'
implies that the resolution of Y-axis is 0.5 millibar per
row.
- T h e h i g h e s t a n d t h e lo w e s t a lt i t u d e s o f t h e Hi s t o r y
Graph will be shown on the display a while later .
- F o r e x a m p l e , 'H I G H E S T 1 1 0 0 . 0 m b' i m p l i e s t h a t t h e
current maximum pressure of the Pressure History Graph
is 1100.0 millibar. 'LOWEST 1000.0m' implies that the
mi n i mu m p re s s u r e o f t h e P r e s su r e Hi s t o r y G ra p h is
1000.0 millibar.
NOTE:
- T h e r e s o l u t i o n o f X - a x i s o f t h e h i s t o r y g r a p h ( t i m e
variable) is fixed as 1 hour.
- The resolution of Y-axis of the history graph ( barometric
pressure variable) is ranging from 0.1, 0.2, 0.5, 1, 2, 5,
10, 20, 50, 100, 200 and 300 millibar.
