MAX (HI) CAPTURE ASSIGNMENT

rEL

GrOSS

Select the desired input value that will be assigned to the Max Capture.

MAX (HI) CAPTURE DELAY TIME

0.0

to

3275.0

seconds

When the Input value is above the present MAX value for the entered delay

time, the meter will capture that value as the new MAX reading. A delay time

helps to avoid false captures of sudden short spikes.

MIN (LO) CAPTURE ASSIGNMENT

rEL

GrOSS

Select the desired input value that will be assigned to the Min Capture.

MIN (LO) CAPTURE TIME

0.0

to

3275.0

seconds

When the Input value is below the present MIN value for the entered delay

time, the meter will capture that value as the new MIN reading. A delay time

helps to avoid false captures of sudden short spikes.

DISPLAY UPDATE RATE

20

updates/second

This parameter configures the display update rate. It does not affect the

response time of the setpoint output or analog output option cards.

AUTO-ZERO TRACKING TIME

0

to

250

seconds

To disable Auto-zero tracking, set this value to 0.

AUTO-ZERO TRACKING BAND

1

to

4095

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 auto-zero tracking 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 undesirable 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 time

parameter = 0.
