LDRIFT

ENABLE

ON
OFF

Enable loaded drift test diagnostics. Tests for drifting load cell
output, which can indicate binding or a deteriorating cell, when the
scale is loaded. The test begins after the load value has been
exceeded and the scale is considered out of motion (see note.)
Once the scale comes to a stable live load, the timer will start. If any
one cell is above the limit after the timer expires and any of the
remaining cells are below the percent limit, no error will occur.
NOTE: If the scale exceeds the motion band in a .5 second interval
after a stable weight, the test is reset until it comes out of motion
again.

LIMIT

0.025000
value (mV)

A m/v reference representing drift allowed for cells on a loaded
scale.

%LIMIT

10
value (percent)

Specifies the percentage difference allowed between the millivolt
output values of a cell and it’s cell mates when the scale is loaded.

TIME

30
value (seconds)

Time delay in seconds between measurements of load cell values.

LOAD

5000.000
value (weight)

A weight value that the scale has to be above before the test will
run.

PKtoPK

ENABLE

ON
OFF

Enable peak-to-peak tolerance diagnostics. A back and forth
millivolt output that exceeds the limit value.

LIMIT

0.125000
value (mV)

Peak-to-peak tolerance noise limit. Specifies a millivolt limit for noise
allowed between stored measurements.

CELLEMU

ENABLE

ON
OFF

Cell emulation. Specifies whether cell emulation can be used to
replace output from a bad load cell.

TYPE

AUTO1
AUTO2
MANUAL1
MANUAL2

Type 1 selections (AUTO1, MANUAL1) use a cell emulation
algorithm designed for truck scales. Type 2 selections (AUTO2,
MANUAL2) use an algorithm for hopper and pallet scales. See
NOTE below for additional information about using Type 2
selections.

AUTO selections specify that the

iQUBE

determines when to apply

cell emulation, based on diagnostic tests, and automatically applies
the selected algorithm to replace the output of a defective cell.

MANUAL selections allow the operator to toggle between actual
and emulated load cell outputs by using the

920i

diagnostic display.

Type 2 selections (AUTO2, MANUAL2) require the “snapshot”
function (Snapshot softkey on the diagnostic display) be executed
while the scale is weighing properly. The snapshot provides the
weight distribution reference used during cell emulation.

MOTBAND

10.00000
value (weight)

Platform motion band. Specifies the amount of weight change
allowed in a 0.5-second interval. Diagnostic tests are run only when
platform stability is within the specified motion band.
