Before Using the Scale

In order to use this scale correctly, we suggest that you read this manual carefully.

Instructions for Use

1. The load placed on the weigh pan must NOT exceed the maximum weighing capacity

of the scale.

2. Protect the scale from high temperatures.

3. Avoid objects impacting with the scale. Do notdrop loads onto the scale orsubject the

weighpan to anystrong shock loads.

4. Please operate or charge the scale in an open area. Do not squeeze the power cord to

avoid wire on fire.

Preparing to Use the Scale

1. Locate the scale ona firm level surface free from vibrations for accurate weight

readings.

2. Adjust the four levelling feet (if fitted) to set the scale pan level.

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

4. 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.

5. Remove any weightthat might be on the weighpanbefore the scale is switched on and

avoid leaving weight on the pan for long periods of time.

6. Allgoods weighed should be placed in the centre of the weighpan for accurate

weighing. The overall dimensions of the goods being weighed should not exceed the

dimensionof the weighpan.

7. Once the scale has been powered on, it willgo throughanLCD display testand it is

ready for use when the display shows zero.

8. The scale requires 15~20 minutes warm up before operation to ensure best accuracy.

9. Please note when the symbol keeps flashing on the screen, the batteries need to

be charged.

10.Introductionof Storage Battery

Thank you for purchasing EXCELL WEIGHING INDICATOR,

to help use the product properly, operate smoothly, and

extend its life cycle, please read this manual carefully.

EXCELL PRECISION CO., LTD

No burning

Caution Corrosion

Due to the storage battery adopt the advanced free-maintaining technique, customers

need not to replenishelectrolyte.

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

rechargeable battery.

1. The batteryshould 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

batteryafter 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

Safety warnings

1. The electrolyte of battery is caustic whichcauses 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.

1-6 Keypad Function

1ON|OFF KEY

Press the

OFF

key to switch the indicator on or off.

ZERO KEY

The

ZERO

keyacts as the zero balance function. If the weighing value is within the range

of zero balance,it canbe re-zeroed and tare cancelled.

Zero Range : OIML&NTEP is ±2% F.S.,and Sri Lanka is ±3% F.S.

1TARE|PT KEY: Tare / Pre-tare key

To TARE:

Place the container onto the scale, until the weight value is stable, press

TARE

key for

zero return and the NET indicationis shown on the display. Place the object onto the

container and the displayshows the net weight value of the object. Remove both object

and container, and negative value of the container will show onthe display. Press

TARE

keyagain to clear “tare value”. The scale returns to zero and NET indication goes off

Tare canbe continuouslydone until tare value=full load capacity

Continuous Tare Press

TARE

key for continuous weight increase/decrease on

platter.

If there is Tare, the pre-tare cannot be done. If there is pre-tare first, and the tare weight

more than pre-tare weight, Tare can be done.

No Tare canbe done under gross weight display mode.

To PRE-TARE:

Press

TARE

key, use keypad to input pre-tare weight. When the cursor flashes on the

rightmost digit, press

TARE

key again to complete.

Pre-tare mode, keypad functionas followed:

NET

GROSS

KEY

In the Tare mode, the screen displays the “

TARE

” icon; press the

NET

GROSS

keyto switch

between the “Net value” and the “Gross value”. When the ”GROSS” arrow



shows up,

the Gross Weight in the screen = Tare weight + Net weight, meanwhile, keys except the

NET

GROSS

key, have no response.

M+|PRINT

KEY

Totalization function. M+/Print functionis available when RS232 is onkeypad transmission

mode. ( output).

This keyis a composite key, while totalizationis shown and weight returns to net zero,

press M+ key to erase memory. RS232 will output MC print format ( output).

If there is new weight added on platter（it is less than20 divisions inBrazil version, no

accumulation ）, a new item willbe added to totalization. If this weight is not taken off,

nothing canbe added to totalization.Display will show the totalization numbers for one

second, thenshow net weight for one second, then the scale returns to the current

weight, and prints out the last item for totalization.
