※ Normal Mode
When the power is off and will not be recovered within 1sec, weight memory will be out and display
wrong weight value when power is recovered.
Also, if there is material over 10% of max. capacity weight in the hopper, the “Un-Pass” display will be
appear and you can not process weighing job. Under this case, please remove material and turn on
DN530N.
If there is material less than 10% of max. capacity weight in the hopper, indicator will initialize
with ”Pass” display, and display “0” whatever the real weight. Under this case, remove the material
and press “Zero” key and input new “Zero” value. Then, new Zero value will be memorized and you
can process weighing job. For “Manual initialization”, press “0” key or enter “Calibration mode”.
Weight Back up Mode
Under this mode, DN530N memories “Zero” value of weighing part. So, when the power is recovered
DN530N can display material weight.

Motion Band Range setting

This is set “Steady” acceptable range of weighing part.
If there is vibration on weighing part, you can set this function and

※ This function is compensate vibration effect on weighing part with acceptable range setting.
During the fixed time period(F06 setting), there is smaller weight variation than Motion band range,
due to vibration, Indicator will display “Steady”, if there is larger weight variation than Motion band
range, due to vibration, Indicator will its weight and “Steady” condition is broken and find new “Steady”
point.
If there are much vibration effect, please set with large set value.

If there is large weight difference over set range within fixed time
period, the “Zero” is breaking and will find new zero point.

Example) Max. Capacity : 100.00kg, Digit : 0.05kg, F04-03 setting

(Auto Zero Range : ± Set value + weight unit)
Using this function, you can get the Zero value without pressing “Zero” key, when there is
remained material in the hopper within Auto Zero Range.
Example) Max. Capacity : 10kg, Digit : 0.02kg, F005-30 setting,
Under this setting, Indicator will display “Zero” automatically, when the weight is within ± 0.30kg(Set value

Zero Value Deduction Setting

Display value with deduction, as much as set value.

F82 XXXXXX
Ex.)Set 1000, actual weight 3000, then display 2000, only.

Analogue Output Setting (only for the analogue option installation)

At the set weight value, analogue output will be maximized.

Ex.) Set 5000, then a weight reached 5000  20mA or 10V will be
output
F83 XXXXXX
But if you need just 3000 of Max. capa, you can input 3000 through
this function, then the weight reached 3000  20mA or 10V will be
output

Span Value Check

At this function, you can check the Calculated Span value.

This Option card converts weight value to Analog Voltage output(0~10V) and transfers to external
devices(Recorder, P.L.C), controlled by voltage output.

4-1. Specification
- Output Valtage : 0~10V DC output
- Accuracy : More than 1/1,000
※As we convert Digital signal(1/30,000 accuracy) to Analogue, so the accuracy will be lower
than Digital signal

This output is adjusted as when the weight is “Zero”, output is 0V and When the weight is “Full
capacity”, output is 10V.
If you need additional adjustment, please adjust with “VR1(Zero)”, “VR2(Span) on the Analog Output
PCB.
※ Remark
This Analog option card converts Displayed weight value(Micro-process data) to analog value on D/A
Converter(Digital to Analog converter)
This D/A Converter has Max. 1/4,000 accuracy, so this output is not suitable for high accuracy
application, like more than 1/3,000.
For 0~5VDC or 1~5VDC analog output, please inform when you inquiry.

- Output Voltage : 4~20mA output (Max.2~22mA)
- Accuracy : More than 1/1,000
- Temperature Coefficient : 0.01%/℃
- Max. Loading Impedance : Max. 500Ω
※As we convert Digital signal(1/30,000 accuracy) to Analogue, so the accuracy will be lower

5-3. Output Adjustment

①. This output is adjusted as when the weight is “Zero”, output is “4mA” and When the weight is
