Operation
The meter is equipped with four buttons behind the
lower panel door used for operation of the meter.
Three buttons labeled F1, F2, and F3 can be
programmed as function keys to perform a variety of
meter functions with a simple push of a button. These
include resetting the total, resetting the meter’s relays
or open collectors, starting and stopping timers,
displaying max/min values and starting/stopping
batches. See
Function Keys & Digital Input Available
for a complete list of settings
available.
A digital input is available on the meter and it may
function in a similar fashion as the function keys to
allow remote operation of a single task.
The max & min readings (peak & valley) reached by
the process can be displayed either continuously by
assigning it to a display line in the
Display
menu, or
momentarily by pressing the F1 key (default) or
assign it to any of the other function key or the digital
input.
Pressing the F1 key cycles through various display
values (e.g. Grand total, max, min); press the Enter
key to lock the display in the current process value
and press the Enter key again to unlock the display.
The relay information menu shows runtime and cycle
count for each relay.
Change the display units within the selected unit class
at any time without the need to re-scale the meter.
Select the desired units via the
UNITS
menu in the
DISPLAY
menu, and the meter automatically
converts the display values to the new unit of
measure.
