1.3 Electrical installation
ELECTRICAL WARNING: The power cable must be connected to an earth-grounded
electrical outlet. The electrical supply must have a circuit breaker with an appropriate
rating to protect from over-current conditions.
For your protection, all electrical (110V or 230V) equipment used out of doors or in wet
or damp conditions should be supplied from a correctly fused power source and
protected by an approved ground fault protection device (RCD, GFCI etc.)
IF IN DOUBT SEEK ADVICE FROM A QUALIFIED ELECTRICIAN.
1.3.1 Pluggable equipment
Pluggable equipment must be installed near an easily accessible socket outlet.
1.3.2 Permanently wired equipment - Isolator requirements
Permanently connected equipment must have a readily accessible disconnect device
incorporated in the fixed wiring such as an isolator or circuit breaker with at least 3mm contact
separation.
The isolator MUST NOT be installed into the flexible power cable supplied with the unit.
1.3.3 Safe handling of equipment with batteries
WARNING: Danger of explosion if battery is incorrectly replaced. Replace only with the
same or equivalent type recommended by the manufacturer. Dispose of used batteries
according to the manufacturer’s instructions.
ATTENTION: Il y a danger d'explosion s'il y a remplacement incorrect de la batterie,
remplacer uniquement avec une batterie du meme type ou d'un type equivalent
recommande par le constructeur. Mettre au rebut les batteries usagees conformement
aux instructions du fabricant.
1.3.4 Wet conditions
Under wet conditions, the plug must be connected to the final branch circuit via an appropriate
socket / receptacle designed for washdown use.
Installations within the USA should use a cover that meets NEMA 3R specifications as
required by the National Electrical Code under section 410-57. This allows the unit to be
plugged in with a rain tight cover fitted over the plug.
Installations within Europe must use a socket which provides a minimum of IP56 protection
to the plug / cable assembly. Care must be taken to make sure that the degree of protection
provided by the socket is suitable for the environment.
1.4 Routine maintenance
IMPORTANT: This equipment must be routinely checked for proper operation and
calibration.
Application and usage will determine the frequency of calibration required for safe
operation.

to go onto the next calibration point or exit the calibration mode. Use the CELLorPRINTkey to select
End.y for yesor End.n for no.
a. If yes is selected, the calibration will be saved and exit to the force mode when the load is
removed.
b. If no is selected, it will go to the next step, requiring a higher calibration or linearization point.
7.12 Press the ZEROkey to confirm.
7.13 The first default standard weight is displayed after Cal.P2being shown. The default standard weight is
100 % of full scale. Use the SELECT, PRINT, CELL, UNIT keys to input the value of the loaded weight.
(More than 10% of full scale weight, and larger than the weight used on CAL.P1) onto scale.
7.14 If calibration was successful, display will show END.Yand the Y is flashing. It is waiting for a command
to go onto the next calibration point or exit the calibration mode. Use the CELLorPRINTkey to select

7.15 Press the ZERO key to confirm
7.16 The first default standard weight is displayed after Cal.P3being shown. The default standard weight is
100 % of full scale. Use the SELECT, PRINT, CELL, UNIT keys to input the value of the loaded weight.
(more than 10% of full scale weight, and larger than the weight used on CAL.P2) onto scale
7.17 Press the ZERO key to confirm
7.18 When calibration is complete CAL.ENDwill be displayed. The indicator will restart, remove the load
from the scale and the indicator will go back to the normal force mode.
8. Force Fine-tune
With this function, the user can adjust displayed force a little, and no need standard weight. But please
note:
(1)The indicator must have been calibrated before this
(2)The range of adjustment is “(current displayed force) x (0.9-1.1)”. it means the range is about ±10%
(3)The “CONFIG-F.ADJ=YES” must be set.
(4) The current unit should be the unit in PRIM.U, and the tare weight is 0.
8.1 To enter this mode, turn on indicator, after indicator displaying 0 force, put a load (suppose: its correct force
is 1230.0lb) onto load cell, then indicator will display the load’s force, say “1234.5 lb”. Press down
ON/OFF and ZERO at same time until first digit flashes, this means indicator has entered into “force
fine-tune” mode.
8.2 Use to input correct force (1230.0). Press the ZERO key, the active correct force will be
displayed and Display will stop flashing. After this, displayed force will be adjusted by this ratio
(1230.0/1234.5) and this ratio will be active until next modification on it.
8.3 To remove the effect of this ratio, there’re two ways: “8.3.1 way” and “8.3.2 way”
8.3.1 Do standard calibration, like in “6.CALIBRATION”
8.3.2 Remove all weight on scale, Press ZERO to make 0 displayed, Put a load onto load cell, a number
will be displayed, suppose it’s 1230.0lb ; Press down ON/OFF and ZERO at same time until first
digit flashes, this means indicator has entered into “force fine-tune” mode.
Press key, the displayed weight will be restored to 1234.5, and then press key to
confirm and exit to normal weighing mode.
9. View ADC output Code
9.1 In this mode, you can examine the stability of weighing system, the increment value of ADC output code
corresponding to the loaded weight.
Note:
The increment of ADC code for FS weight must be larger or equal to 10 times of selected
display division; otherwise, the calibration cannot be properly completed. e.g. The display
division is 0.1kg. Load 100kg standard weight on the platform, the increment of ADC code
should be at least more than 10x100kg/0.1kg= 10x1000=10000. In this case, the indicator can
be calibrated. Otherwise, smaller division needs to be Chosen.
The variation of ADC code should be small; otherwise, the calibration cannot properly complete
also.
