EXCELL PRECISION CO., LTD.

Thank you for purchasing EXCELL waterproof weighing scale. In order to use the scale properly, please read this instruction carefully before use. If you have a problem concerning the scale, please contact your supplier.

Instruction for Use

1. Please keep the scale in a cool dry place. Do not store it at high temperature.

2. Avoid objects impacting with the scale. Do not drop loads onto the scale or subject the weigh pan to any strong shock loads.

3. The load placed on the weigh pan must not exceed the maximum weighing capacity of the scale.

4. If the scale is not going to be used for some time, please clean it and store it in a plastic bag in dry conditions. A desiccant sachet may be included to prevent any moisture build up.

Preparing To Use the Scale

1. Adjust the four levelling feet (if fitted) to set the scale pan level using the spirit level bubble located at the front of the scale.

2. Avoid operating the scale in direct sunlight or drafts of any kind.

3. If possible avoid connecting the scale to ac power outlet sockets which are adjacent to other appliances to minimise the possibility of interference affecting the performance of the scale.

4. Remove any weight that might be on the weigh pan before the scale is switched on and avoid leaving weight on the pan for long periods of time

5. All goods weighed should be placed in the centre of the weigh pan for accurate weighing. The overall dimensions of the goods being weighed should not exceed the dimension of the weigh pan.

6. We suggest to warm up the scale for 15~20 minutes before operation to ensure best accuracy.

7. Please note when the symbol keeps flashing on the screen, the batteries need to be replaced.

8. Introduction of Storage Battery

02005311 ZSME3000000272

2

EXCELL PRECISION CO., LTD.

Due to the storage battery adopt the advanced free-maintaining technique, customers need not to replenish electrolyte.

The scale should be recharged every 3 months to prevent failure of the internal rechargeable battery.

1. The battery should be charged for 8~10 hours.

2. The temperature of battery should below 45

.

Maintaining

1. Please do not discharge with over-current when using the battery. Please charge the battery after discharging current.

2. Please take down the battery when the scale is not used for a long time or break the connection of cathode.

3. Do not short the battery terminals to check whether there is current. Please check whether the connection point is firm to guarantee good connection.

4. The battery should be replaced by specialized person.

No reverse-battery or the product will be damaged.

a) Anode of battery should be connected with Anode of product battery

( usually red cable

) b) Cathode of battery should be connected with Cathode of product battery (usually brown cable or black cable) c) See the picture following

Brown cable(or black cable) connected with Anode of battery

Red cable connected with

Cathode of battery

Safety warnings

1. The electrolyte of battery is caustic which causes metal, cotton, etc to corrode.

2. The hydrogen will be resolved when using or charging the battery and it will cause explosion when approaches fire.

The scale is in the gross mode. The display shows the goods and any

P c s container weight. This Gross status indication is on when the TARE function is used.

Keyboard Function

ON/ZERO KEY

This key possesses two functions: Power On and Zero function.

OFF KEY

When the scale is switched on, press the

OFF

key, the scale will switch off.

TARE KEY

The tare function will not operate during the following conditions:

02005311

ZSME3000000272

EXCELL PRECISION CO., LTD.

1. When the scale powers on if the weight is negative and after a container is placed on the weigh pan if the weight is still below zero.

2. The tare value is over the full scale capacity.

UNITS KEY

Press the

UNITS

key to switch weight units; the icons will indicate the active units.

NET/GROSS KEY

In the Tare mode, the screen displays the “TARE” icon; press the

NET/GROSS

key to switch between the “Net value” and the “Gross value”.

1-4 Operating the Scale

POWER ON

When the scale is off, press the

ON/ZERO

key, the scale will switch on.

POWER OFF

When the scale is on, press the OFF key, the scale will switch off.

ZERO

When the weigh pan is empty (free of load) and the display is not showing zero, press the

ON/ZERO

key to zero the scale. At zero, the “

Æ

0

Å

” indication is on.

When the weight value is within the zero range, the zero function operates to zero the scale or cancel the tare function.

Zero range: The OIML & NTEP models have a zero range of

±

2% of Full Scale. The

Sri Lanka model has a zero range of

±

4% of Full Scale.

SWITCHING UNITS

Press the

UNITS

key to switch weight units, the icons or arrows will indicate the active units as appropriate. The units available are dependent on the exact scale model.

After power off, the scale will memorize the active units. When the scale is powered on again, it displays the previously active units.

TARE FUNCTION

(1) Put a container on the weigh pan and after the weight is stable, press the

TARE

key to zero the weight of the container. The screen displays the “Net” icon.

(2) Put the goods in the container, the screen displays the net weight value of the goods.

(3) Remove the full container; the screen displays the negative weight value of the container. At this time pressing the

TARE

key again will cancel the tare and the scale reverts back to zero. The “Net” icon is switched off.

The tare function can be operated continually to the full weighing capacity of the scale.

Continual tare operation is adding or removing tare objects on weigh pan and pressing the

TARE

key each time.

NET/GROSS FUNCTION

In the Tare mode, the screen displays the “Net” icon, press the

NET/GROSS

key to switch between the “Net value” and the “Gross value”.

When the GROSS icon is on, the weight value on the display is the total amount of the tare value and net value.

At the Gross status, only

OFF

and

NET/GROSS

keys are functional.

NET/GROSS

key is only used in Tare mode.

SIMPLE COUNTING FUNCTION

(1) Use the UNITS key to enter into the “PCS” mode

(2) Press the NET/GROSS key to select the counting sample size

(S = 10, S = 20, S = 50, S = 100, S=200).

The LCD shows , , , , in order

.

(3) Put the samples on the weigh pan and press the UNITS key, the screen displays

“------”. After the sampling process is complete, put the goods on the weigh pan and the screen shows the quantity of the items.

The sample weight should be heavier then the minimum capacity of the scale (20d), If

.

.

.

.

.

.

.

.

.

The weight of a sample should be heavier than the 0.2d (d=division), or the arrow pointing to the icon will be on.

contain errors.

To power off in this mode, the scale will memorize the “Pcs” unit. When the scale is powered on again, it directly enters the simple counting mode.

While the “Auto unit weight average” function is available in the Advanced Function, the goods on the weigh pan are 5pcs greater than the sample size and less than double the sample size, the scale will automatically re-sample the unit weight.
