MAX CAPTURE DELAY TIME
When the Input Display is above the present MAX value for the entered
delay time, the meter will capture that display value as the new MAX reading.
A delay time helps to avoid false captures of sudden short spikes.
0.0
MIN CAPTURE DELAY TIME
When the Input Display is below the present MIN value for the entered delay
time, the meter will capture that display value as the new MIN reading. A delay
time helps to avoid false captures of sudden short spikes.

DISPLAY OFFSET VALUE
Unless a Zero Display was performed or an offset from Module 1 scaling is
desired, this parameter can be skipped. The Display Offset Value is the
difference from the Absolute (gross) Display value to the Relative (net) Display
value for the same input level. The meter will automatically update this Display
Offset Value after each Zero Display. The Display Offset Value can be directly
keyed-in to intentionally add or remove display offset. See Relative / Absolute
Display and Zero Display explanations in Module 2.

DISPLAY UPDATE RATE
This parameter determines the rate of display update. When set to 20
updates/second, the internal re-zero compensation is disabled, allowing for the
fastest possible output response.

The meter can be programmed to automatically compensate for zero drift.
Drift may be caused by changes in the transducers or electronics, or
accumulation of material on weight systems.
Auto-zero tracking operates when the readout remains within the tracking
band for a period of time equal to the tracking delay time. When these
conditions are met, the meter re-zeroes the readout. After the re-zero operation,
the meter resets and continues to auto-zero track.
The auto-zero tracking band should be set large enough to track normal zero
drift, but small enough to not interfere with small process inputs.
For filling operations, the fill rate must exceed the auto-zero tracking rate.
This avoids false tracking at the start of the filling operation.
Fill Rate ≥ tracking band
tracking time
Auto-zero tracking is disabled by setting the auto-zero tracking parameter = 0.
