Noise Filter
Averages the input signal over a period of
time between 1 and 16 seconds to
dampen the effects of a noisy signal that
causes a jumpy display.
Filter Bypass
0.0 to 99.9% of full scale. Input signal
changes greater than bypass value are
displayed immediately.
Recalibration
Recalibration is recommended at least
every 12 months.
Max/Min
Display
Max/min readings reached by the process
are stored until reset by the user or until
power to the meter is turned off.
Tare
If the totalizer is disabled, the Tare
function zeros out the meter to remove
the weight of a container. Tare function
can be assigned to a function key or the
digital input.
Password
There are three separate passwords
available that can be set independently of
each other: Main, Total, and Grand Total.
The Main password prevents access to
the meter Programming Mode. Total and
Grand Total passwords prevent resetting
