2 FEATURES
2.1 - Batching
To access batching features, the controller's Mode must be set to Batch (see 6.2F).
It is then possible to perform the following functions from the button or rear
input pins:
Batch This function is used to display the live weight of the system but take
regular 'batches' of product without continually changing the setpoint.
When the Batch function is activated the display will tare and SP 1 and
SP 2 will turn on.
Batch Reset Resets the batch value to zero and halts any current batching operations.
Batch Pause Pauses the batching process and holds the current batched weight on
the display.
Batch Resume Resumes the batching process aer it has been paused, or if power was
lost during a previous batch.
See 6.2H–K and Appendix A for instructions on setting up and operating these features.
2.1A - Gain in Weight (GIW) Batching Direction
The Batching Direction parameter is set in 6.2G, and should be set to GIW (Gain
in Weight) for applications where the weight increases as product is added to the
weighing system.
E.g. Setting a setpoint value of 50Kg for SP 1 and 45Kg for SP 2 and enabling GIW batching will al-
low the user to ll a container to 50Kg, with a potential speed change at 45Kg. (See 2.1C for an
alternative method of setting up SP 2.)
The cycle is initiated when the Batch function is triggered. The display will tare, and when 45Kg
net weight is shown, SP 2 will drop out. As product continues to feed, at 50Kg SP 1 will drop
out, halting the ll.
If Flash Gross is enabled (see 6.2L) the gross weight will be displayed (E.g. Now 1050Kg, if the
starting gross weight was 1000Kg). The user can then trigger the Batch function again to call
another 50Kg batch.
2.1B - Loss in Weight (LIW) Batching Direction
The Batching Direction parameter is set in 6.2G, and should be set to LIW (Loss in
Weight) for applications where the weight decreases as product is removed from the
weighing system.

PRO-WEI100-MAN-19V01 (0225) Copyright © 2019 Dene Instruments

E.g. Setting a setpoint value of 50Kg for SP 1 and 45Kg for SP 2 and enabling LIW batching will al-
low the user to ll a container to 50Kg, with a potential speed change at 45Kg. (See 2.1C for an
alternative method of setting up SP 2.)
The cycle is initiated when the Batch function is triggered. The display will tare, and when 45Kg
net weight is discharged, SP 2 will drop out. As product continues to be discharged, at 50Kg SP 1
will drop out, halting the product ow.
If Flash Gross is enabled (see 6.2L) the gross weight will be displayed (E.g. Now 950Kg, if the
starting gross weight was 1000Kg). The user can then trigger the Batch function again to call
another 50Kg batch.
In this mode if there is not enough product to drop a batch, then the instrument will advise the
operator by showing the message Low Product. If gross > SP 1, the Batch Value is reset to zero
and the display ashes Batch. SP 1 is turned on (and SP 2 if set up). If gross < SP 1, batching is
not started.
2.1C - Setpoint Tracking
In applications where the batch weight is continuously being changed, it is possible
to congure SP 2 so that it tracks SP 1, and always turns o at a xed amount below
the required batch weight.
E.g. If your initial batch weight was 100Kgs and you wanted SP 2 to turn o 5Kgs before it reached
the batch weight, you would set up the SP 1 value for 100Kgs and the SP 2 value for -5Kgs, and
set the Trail SP 1 option to on (see 6.2D).
This would cause SP 2 to turn o at 95Kgs (i.e. 100Kgs - 5Kgs). Then if you wanted the next
batch weight to be 200Kgs, you only need to change SP 1 to 200Kgs, and without altering
SP 2 it will now turn o at 195Kgs (200Kgs - 5Kgs).
2.2 - Input signal averaging
This controller has input signal averaging (see 6.5), to reduce noise and optimise
stable measurement. If your input signal contains large noise spikes, you can increase
the size of the Averaging Window to ensure that these are still averaged. If the
change in input exceeds the Averaging Window value it will not average, ensuring
fast response when there are large dierences between readings.
Note that increasing the window size too far will reduce the ability of the controller to respond
quickly to real changes in input signal.
2.3 - Tare
To access tare features, the controller's Mode must be set to Normal (see 6.2F). It is
then possible to Tare/Reset Tare from the button or rear input pins:

PRO-WEI100-MAN-19V01 (0225)Copyright © 2019 Dene Instruments
5
Tare This feature 'zeroes' the display, and is usually used to deduct the weight
of the container from the total weight, leaving only the weight of the
product.
Tare Reset This feature clears the current tare value and shows the gross weight on
the display.
See 6.2H–K and Appendix A for instructions on setting up and operating these features.
2.4 - Zero maintenance
The Zero Maintenance feature is used to automatically compensate for slow dri in
loadcell output due to factors such as temperature change, rain and dust accumula-
tion over time.
When Auto Zero is enabled (see 6.4B), the controller display will zero automatically
if changes to the loadcell are within the user specied Capture Band, Motion Band
and Zero Band parameters (see 6.4C–E):
Capture Band (6.4C) This is the maximum number of display counts that the controller
will automatically zero within. The Capture Band is referenced to
the current zero value. If the input value on the load cell is not
within the Capture Band setting then the controller displays the
current loadcell value and does not zero.
Capture Band can be set from 1 to 254 counts, and should always be
set to less than the smallest weight to be measured. Setting the Cap-
ture Band to 0 will turn the auto zero feature o.
Motion Band (6.4D) This provides a rate of change limit setting, to determine the num-
ber of counts/second allowed within the Capture Band. If the
count change is within the Capture Band, but the speed of the
count change is more than the selected Motion Band, then the
controller displays the current loadcell value and does not zero.
The Motion Band can be set from 0 to 255 counts. Typical value is 1
or 2 counts/sec.
Zero Band (6.4E) This provides a limit for the number of counts of zero offset
allowed to accumulate, relative to the calibrated zero setting. If
the accumulated zero offset becomes greater than this window,
then the controller displays the current loadcell value and does
not zero.
The suggested limit for the Zero Band is 2% of the calibrated span. If
the controller fails to zero, check for mechanical or electrical faults.

6.3 - Calibration
This unit has been calibrated for 0–10,000 counts (2mV/V sensor gain at full scale).
A _ _ _ CALIBRATION TECHNIQUE scrolls across the display and toggles with
SKIP. Press to skip to 6.4, or use the and buttons to select a calibration
method: AUTO, MV/V, ZERO, E_CAL, or CALSET, and press to continue.
¨If you selected AUTO, complete steps 6.3B–F now.
¨If you selected MV/V, complete steps 6.3G–I now.
¨If you selected ZERO, complete step 6.3J now.
¨If you selected E_CAL, complete steps 6.3K–L now.
¨If you selected CALSET, complete steps 6.3M–N now.
¨If you selected SKIP, skip to 6.4 now.
AUTO calibration uses zero and span values to calculate the scale and oset. This is the most
accurate calibration method, but requires known low and high input signals, usually supplied
by test weights. Zero and span calibration procedures are performed separately.
MV/V uses values from the load cell manufacturer’s test certicate.
ZERO allows manual adjustment of the calibrated zero oset.
E_CAL allows the user to view and edit the electronic calibration values (zero oset and scale
factor). These two values are updated when any calibration is performed. Noting these values
and entering them into another instrument will copy the calibration. You may also 'trim' these

This is updated aer each calibration to show the internal SCALE FACTOR E Cal value.
E_Cal calibration is now complete. You will be directed back to the operational
display. (To enter step 6.4, you must select SKIP at 6.3A.)
Cal set selection
M _ _ _ SELECT CAL SET scrolls across and toggles with the current selection. Use
the and buttons to choose either SET 1 or SET 2, and then press .
This feature allows you to save two sets of calibration values on the controller, and to roll back
to a previous calibration, if necessary. The set that you select will be the active calibration set.
N _ _ _ CALIBRATION TECHNIQUE scrolls across the display and toggles with
SKIP. You are now back at 6.3A. Press to skip to 6.4, or use the and
buttons to select a new calibration method, and then press .
6.4 - Zero maintenance
See Section 2.4 for more information on zero maintenance parameters.
A _ _ _ ZERO MAINTENANCE scrolls across the display and toggles with SKIP. Press
to skip to 6.5, or the button and then to ENTER zero maintenance.
B _ _ _ AUTO ZERO scrolls across the display and toggles with the current auto
zero selection. Use the and buttons to select ON or OFF, and press .
¨If you selected ON, continue to 6.4C now.
¨If you selected OFF, skip to 6.4E now.
If AUTO ZERO mode is ON, the controller’s oset will be automatically adjusted so that the
instrument reads zero when it senses that the scale is not loaded (see 2.4).
C _ _ _ CAPTURE BAND scrolls across the display and toggles with the selected
capture band. Adjust this value using the and buttons, and then press .
This is referenced to the current zero value, and is the maximum number of display counts that
the controller will zero within. CAPTURE BAND can be set from 1to 254 counts, and should
always be set to less than the smallest weight to be measured.

D _ _ _ MOTION BAND scrolls across the display and toggles with the selected
motion band. Adjust this value using the and buttons, and then press .
This provides a rate of change limit setting, to determine the number of counts/second allowed
within the CAPTURE BAND. MOTION BAND can be set from 0to 255 counts. Typical value is
1or 2counts/sec.
E _ _ _ ZERO BAND scrolls across the display and toggles with the selected zero
band. Adjust this value using the and buttons, and then press .
This provides a limit for the number of counts of zero oset allowed to accumulate, relative to
the calibrated zero setting. If the accumulated zero oset becomes greater than this window,
then the controller displays the current loadcell value and does not zero. The suggested limit
for the ZERO BAND is 2% of the calibrated span.
6.5 - Averaging
Your controller has input signal averag-
ing, optimising stable measurement.
If the change in input exceeds the
averaging window value it will not
average, ensuring fast response when
there are large dierences between
readings. (E.g. When product is being
dropped into a bag.)

A _ _ _ AVERAGING PARAMETERS scrolls across and toggles with SKIP. Press
to skip to 6.6, or the button and then to ENTER averaging setup.
B _ _ _ AVE SAMPLES scrolls across the display and toggles with the currently
selected averaging. Using the and buttons, alter the number of input
samples that the controller will average, and then press .
Increasing the number of samples will stabilise measurement, but it will also slow down re-
sponse rates. A typical value is 4.
C _ _ _ AVE WINDOW scrolls across the display and toggles with the currently
selected averaging window value. Using the and buttons, alter the signal
averaging window. Then press .
If your input signal contains large noise spikes, you can increase the size of the averaging win-
dow to ensure that these are still averaged. However, increasing the window size too far will

reduce the ability of the controller to respond quickly to real changes in input signal. Setting
AVE WINDOW to 0will give continuous averaging as per the selected averaging samples. A
typical value is 10% of your system capacity.
6.6 - Analog output setup
N.B. All new units are calibrated before shipping. Recalibration is only necessary if settings
are wiped or the unit's accuracy requires verication aer a long period of use. e.g. 1 year.
A _ _ _ ANALOG OUTPUT SETUP scrolls across the display and toggles with SKIP.
If your controller does not have analog output installed, (or you do not wish to
congure your analog output now), press to skip to 6.7.
Otherwise, press the button and then to ENTER analog output setup.
B _ _ _ DATA SOURCE FOR ANALOG O/P scrolls across the display and toggles
with the current analog output data source. Use the and buttons to
select an option from: NET/BATCH, or LIVE, and then press .
Note that where NET/BATCH is indicated, the option that will be displayed is controlled by the
weighing mode selected in 6.2F. NORMAL mode = NET, BATCH mode = BATCH.
C _ _ _ LOW SCALE VALUE FOR ANALOG O/P scrolls across the display and tog-
gles with the currently selected low scale display value. Use the and but-
tons to enter your cal low position, and then press .
D _ _ _ HIGH SCALE VALUE FOR ANALOG O/P scrolls across the display and
toggles with the currently selected high scale display value. Use the and
buttons to enter your cal high position, and then press .
To calibrate your analog output, see Section 10.
Factory analog output calibration is precisely set before shipping this instrument,
and should not be adjusted unless advised by the manufacturer.
6.7 - Serial setup
A _ _ _ SERIAL SETUP scrolls across the display and toggles with SKIP. If your
controller does not have a serial port installed, (or you do not wish to congure
your serial options now), please press to skip to 6.8.
