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 that are greater than the bypass
value are displayed immediately.
Recalibration
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.

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 the total
