5.6 Calibration Settings
Calibration Settings are password protected. Default password (123456).
Quick Calibration
Set DP Set the decimal point position - this allows the decimal point to be positioned
anywhere between leftmost 3-digit .Permitted values are 1, 2 and 3.
Set AG This is the reference point for the calibration under load. The weight signal used for
calibration should be as close as possible to the maximum allowable display value (Maximum
Capacity) so as to ensure optimum calibration accuracy. When calibrating the span, the
actual value of the calibration weight must be entered as a parameter of the AG.
For example if the output 500lb is required for the weight placed on the scale, then the
005000 counts should be entered in to the display when DP is 1.
Unit Unit of measure for the calibrated weight. This is the reference point for the lb to kg conversion.
Unit of measure can be selected as lb or kg.
CZ Set the calibration zero point - this is the reference point for all weight calculations. Make sure
there is no any weight on the scale when performing this function, Also it will give an Error if there is
any motion on the scale.
CG Set the calibration gain - this is the reference point for the calibration
under load. Placed the weight on the scale that was entered under the AG value and select CG. It will
Save Save the calibration using this setting.
Maximum Capacity - Set the maximum allowable output value using this setting. This setting can be
set to 0 Over
. From this parameter the value of maximum capacity can be view or edit.
Default 999999
Minimum Capacity - Set the minimum allowable output value using this setting. Permitted values for
this parameter are between the lower limit of -999999 and the upper limit of 0.This value will
. From this parameter the value

Default (-999999)
Zero Range This is the range in increments within which the weighing scale can be zeroed.
Permitted values are between the lower limit of 0 and the upper limit of 999999. A value of zero
enables the standard zero range of +/-2% of max. The value of zero range can be view or edit. When

Filter Settings
The parameter exists for set the digital filter via the Filter value setting, and this filter can be adjusted
to eliminate most unwanted disturbances. Note that this filter is positioned immediately after the A/D
Converter, therefore have an effect on all aspects of weigher operation.

Options:
IIR 18-0.25 Hz
FIR 19.8-2.5 HZ
Default IIR
Filter Value The digital Low pass filter value can be changed according to the Filter Mode setting.

5.8 Functions
Tare Mode This setting sets the tare mode. The tare modes are defined in the option table below.
Options:
Tare Mode Allow tare of negative
values
T.Mod1 Yes
T.Mod2 No
Default T.Mod1
Zero Tracking This function set the zero track band in divisions (d). Zero tracking will be
performed only on results less than +/-(0.5 * Zero Tracking) at a rate of 0.4 d/sec where d = display
step size. The zero can only be tracked to +/- Zero range. A value of zero turns off the zero tracking.
Default 0
Store Zero Value This function sets the zero mode to volatile (off) or non-volatile (on). If set to
-volatile), every set/clear zero will write the value directly to the EEPROM.
Default off
Store Tare Value This function sets the tare mode to volatile (off) or non-volatile (on). I
(non-volatile), every set/clear tare will write the value directly to the EEPROM.
Default off
Initial Zero Range Define the initial zero range (0...999999 d). If initial zero range is non-zero the
device will perform an automatic Set Zero when the weight stabilizes with the No-motion settings and
the weight is within the initial zero range.
