5 Explanation of functions
The PM4 setup and calibration functions are configured through a push button sequence. The
three push buttons located at the rear of the instrument (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
calibration 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 push button (in some cases both simultaneously) when the required function is
reached. See the flow chart example on the following page.
