Special Notice
While installing the load cell, power cord hookup or replacing a new rechargeable
battery, the indicator housing must be opened. It must be done by a technician assigned
by your electronic indicator provider to avoid affecting the waterproof ability of this indicator.
Before opening the housing, make sure the indicator is dry, if there is any liquid on it,
please wipe it with a clean cloth.
HOW TO INSTALL THE HOUSING
After installing the load cell, power cord hookup or replacing a new rechargeable battery,
the housing must be screwed by the assigned order as shown below. Screw lightly first,
then screw them tight using a 12 kgf-cm torsion.
P.s. Please use a torsion-adjustable screw driver.

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.
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 not drop loads onto the scale or subject the
weigh pan to any strong 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 on a 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 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.
6. 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.
7. Once the scale has been powered on, it will go through an LCD display test and 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

ZSME300000288
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.
No burning

Low Battery Warning
Please note when the (
) symbol keeps flashing on the display, the internal battery
should be recharged.
 The scale will turn off automatically after a few hours when the low battery warning
symbol shows up. The scale must be fully charged, before operating again.
 When the battery status indication is full, the power is about 6.1V; Each block is about
0.2V; When the battery warning symbol shows up, the power is about 5.4V.

ON|ZERO KEY
 When the power is off, press ON|ZERO key to switch the indicator on.
 When the power is on, press ON|ZERO key to return to zero.
 Zero Range : OIML&NTEP is ±2% F.S., and Sri Lanka is ±3% F.S.

TARE|PT KEY: Tare / Pre-tare key
To TARE:
Place the container onto the scale, until the weight value is stable, press TARE|PT key for
zero return and the NET indication is shown on the display. Place the object onto the
container and the display shows the net weight value of the object. Remove both object
and container, and negative value of the container will show on the display. Press TARE|PT
key again to clear “tare value”. The scale returns to zero and NET indication goes off.
 Tare can be continuously done until tare value=full load capacity
 Continuous Tare  Press TARE|PT 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 can be done under gross weight display mode.
To PRE-TARE:
Press TARE|PT key, use keypad to input pre-tare weight. When the cursor flashes on the
rightmost digit, press TARE|PT key again to complete.
Pre-tare mode, keypad function as followed:
ON|ZERO  upward key (0~9 digit entry)
NET|B/G  move cursor leftward
UNIT
 downward key (0~9 digit entry)
TARE|PT
 move cursor rightward
UNIT KEY
Press the UNIT key to switch weight units; the display icons will indicate the active units.
NET|B/G KEY
In the Tare mode, the screen displays the “TARE” icon; press the NET|B/G key to 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
1NET|B/G key, have no response.

This key is a composite key, while totalization is 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 than 20 divisions in Brazil version, no
accumulation ), a new item will be added to totalization. If this weight is not taken off,
nothing can be added to totalization.Display will show the totalization numbers for one
second, then show net weight for one second, then the scale returns to the current
weight, and prints out the last item for totalization.
 To clear totalization data, press M+ key to let display shows up totalization numbers,
then press the M+|PRINT key again, to clear totalization data. RS232 will print out
totalization numbers, total weight, etc.
P.s. Weight must return to net zero if to perform clear function.

Foot Switch Mode
This function is optional. Use
to select TARE|PT key as “ZERO” or “PRINT” key
 If “PRINT” key is set (
= 10/11), all totalization data will be printed out, and
totalization will be cleared.
 If it is Brazil version and foot switch is set as Print function, it has totalization function
and print function.
Simple Counting Mode
Use UNIT key to switch unit to Pcs, to go into simple counting mode.
1. Use NET|B/G key to select a sample number from “10, 20, 50, 100, or 200”. Display will

in an sequential order by pressing
NET|GROSS key.
2. Select a sampling number, and put appropriate weight on platter, and press UNIT key.
Display will show “
”. The scale will go into counting mode after weight is
stable, and display will show the sample number.
 Unit weight insufficient (
): Sample unit weight is less than 0.2d or total sample
weight is less than 20d (d=division)
 While sampling, if there is insufficient sample or unit weight insufficient indication “”,
the scale is still usable, but there may be slight inaccuracy.
 After Power-off, the scale automatically memorizes the sampling number, and it is
available when “Pcs” unit is selected next time.
 If the setting is “automatic average unit weight “, if the object on platter > the previous
sampling number more than 5 pcs, and also < less than 100% the previous sampling
number, the scale will execute unit weight calibration automatically.
