Arithmetic and Wind Speed/Direction mode functions
The LD display setup and calibration functions are configured through a push button sequence. The
three push buttons located on the input pcb (also at the front on some display options) are used to alter
settings. Two basic access modes are available:
FUNC
mode (simple push button sequence) allows access to commonly set up functions such as alarm
setpoints.
CAL
mode (power up sequence plus push button sequence) allows access to all functions including cali-
bration parameters.
Once
CAL
or
FUNC
mode has been entered you can step through the functions, by pressing and releasing
the
F
push button, until the required function is reached. Changes to functions are made by pressing the
^
or
v
push button (in some cases both simultaneously) when the required function is reached.
