P
button function - a only applicable models with front panel
P
buttons. The
P
button may be
set to operate one of the following selections:
•
NONE
-
P
has no operation.
•
Hi
- Peak memory. This function allows the
P
to be used to view and reset the peak
memory. The peak memory is the maximum positive display value (conductivity/resistivity
or ppm) achieved since the peak memory was last reset. To view the peak memory press the
P
momentarily, the display will show the indicator
PHi
followed by the peak reading. This
peak reading will be retained on the display for approximately 20 seconds before returning to
“live” display readings, alternatively the display can be forced to return to “live” measurement
by pressing the
F
. To reset the peak memory hold the
P
pressed for 3 seconds or remove
power to the display.
•
Lo
- Valley memory. Operates in the same manner as the
Hi
function above but operates
on the lowest value in memory. The indicator
P Lo
will be seen prior to the valley memory
value.
•
HiLo
- Peak/valley memory. Operates in the same manner as the
Hi
and
Lo
memories
but allows toggling between high and low values i.e. press once momentarily to view peak
high and again momentarily to view peak low.
•
tARE
- display tare. Short circuiting the remote input pins momentarily will allow toggling
between nett and gross values (shown as
NEtt
and
GROS
). If the remote input is short
circuited for approx. 2 seconds the display will be tared and will show zero. The tare will be
lost if power is removed.
•
ZERO
- display zero. Zeroes the display in same manner as the tare function except that
the zero is not lost when power is removed and the display will zero as soon as the remote
input is shorted. When the
ZERO
operation is used the gross value cannot be recalled and
the input at the time of the
ZERO
operation will become the new zero point.
