02005159 ZSME300000225 3 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. Screwing order: 1 2 3 4 5 6

02005159 ZSME300000225 4 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 symbol keeps flashing on the screen, the batteries need to be charged. 10. Introduction of 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.

02005159 ZSME300000225 5 No burning Caution Corrosion 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 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. Brown cable(or black cable) connected with Anode of battery Red cable connected with Cathode of battery Warning explosion Children faraway

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. 1-6 Keypad Function 1OFF KEY Press the OFF key to switch the indicator off. 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. 1TARE|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|GROSS  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|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”. When the ”GROSS” arrow  shows up, the Gross Weight in the screen = Tare weight + Net weight, meanwhile, keys except the 1NET|GROSS key, have no response. 1 M+|PRINT KEY Totalization function. M+/Print function is available when RS232 is on keypad transmission mode. ( output).

02005159 ZSME300000225 9 Pcs 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. F KEY Function key (In , select F key as “MC” or “HR”) 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|GROSS key to select a sample number from “10, 20, 50, 100, or 200”. Display will show , , , , 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.
