Engineering units
These settings affect the engineering units that will be used for many other settings. The engineer-
ing units can be changed at any time. Note that you must enter settings in the same units as set
here eg 750 g calibration weights must be entered as 0.75 kg if the weight units are kg.
Q2111 units metric/imperial [0=both, 1=metric, 2=imperial] 8042, g0
Selects between metric units, imperial units or any if a mixture of metric and imperial units is required.
Q2112 weight units 8044
1
kg=101
These are the engineering units that will be used for all weight settings except the totaliser (eg kg).
Q2114 flowrate units 8048, g0
2
kg/h=162
These are the engineering units that will be used for all flowrate settings (eg t/h).
Q2115 totaliser units (TU) 8050, g0
3
kg=101
These are the engineering units that will be used for the totaliser (eg t).
Measuring range
If a signal exceeds the capacity setting, it will display as over-range. Therefore the range settings
should be set larger than the maximum value that will occur during normal operation.
The measuring range affects the way many other settings are stored and displayed. These other set-
tings are stored internally as a percentage of the relevant capacity. Once these capacities are set, the
other settings, eg the analog output, will automatically work. Note that, in particular, the ‘weight capac-
ity’ must be set before any other weight settings are entered.

* Q2121 weight capacity (WCAP) 8060 100.0 kg,t,g
* Q2123 flowrate capacity 8064 1000 t/h,kg/h
Display resolution
The division settings affect to what resolution a signal is displayed. For most practical weighing sys-
tems, the total number of divisions will be within the range 500 to 5000.
Q2131 weight division 8070, g0 0.1 kg,t,g
Q2133 flowrate division 8074, g0 2 t/h,kg/h
Trade setup
Q2141 trade use check 8702, g7
Displays off if instrument is not suitable for trade use. Information on what needs changing for trade
use is shown.
Q2142 calibration verification code 8714, g7
Whenever a setting is changed which may alter the trade calibration of the instrument, this value will
change. It can be used to check if the calibration has been changed since this value was last recorded.
Q2143 calibration lock 8078, g7 off=0
When set to on, all settings which effect the trade calibration are locked.
Weight change constants
These weight change constants define the operation of the loss in weight or gain in weight system.
Enter hopper filling setpoints
If the weigh hopper is to be automatically filled whenever it has nearly emptied, the hopper high and
low weight setpoints must be set up.
The ‘material feed’ output is used to control the filling system. The high setpoint is set to the weight the
filling should stop. Usually this is around 60-50% of the hopper capacity. The low setpoint is the weight
at which the filling of the weigh hopper should start. Usually this is around 5-20% of the hopper capac-
ity.
To disable the filling control, set the low setpoint to 0.
