A&D EM Series Instruction Manual

Step 2 While taking care not to pinch the cable, secure the pole to the weighing platform, using two screws. This manual describes how the EM Series Digital Platform Scales work. Step 3 Secure the bracket to the pole, using a nut and screw. Please read this manual completely before using the scale. Step 4 Connect cable A to cable B. Step 5 Bundle the excess cable and insert it into the pole. Step 6 Attach the display to the bracket. CAUTION 　The scale is a precision instrument. When installing the scale, consider the following conditions to get the most out of your scale. Install the scale where it is not exposed to direct sunlight, where the temperature and relative humidity is stable and where there is no dust and draft. Install the scale on a solid and level surface which is free from vibration. The scale is not waterproof. Do not use it where it will get wet. Do not disassemble the scale. Do not open the case to repair or modify it. That may cause a fire or damage to the scale. Damage caused under such conditions will void the warranty. If the scale malfunctions, stop using it immediately. Contact the local A&D dealer. Three weight display resolutions are available, normal (1/3000), high (1/6000 or 1/7500), and higher (1/12000 or 1/15000). Two weighing platform sizes are available. The EM-KAM has a smaller pan and the EM-KAL has a larger pan. As a power source, either the AC adapter or internal rechargeable battery can be used. The counting function easily counts the number of objects of the same weight. The optional EM-03 serial interface can transmit the weight value to a personal computer or a printer. The following options are available for the EM series: EM-03 RS-232C serial interface EM-12 Adjustable bracket EM-13 Stabilizing foot ( for EM-30KAM , -60KAM ) EM-14 Desktop / Wall-mount stand When unpacking, check whether all of the following items are included. EM-15 Protective cover ●The EM series scale ●screws and nut ●AC adapter ●Instruction manual EM-16/17 Extension cable ( 3m/5m ) Note: Confirm the AC adapter type is correct for your local voltage Adjust the level of the scale, using the leveling feet. Confirm that the bubble of and receptacle type. the spirit level is in the center of the level. The best installation conditions are: stable temperature (-10℃ to 40℃） and relative humidity ( less than 85% ), solid and level surface, no drafts or vibration, no direct sunlight. Do not install the scale where there may be static electricity or sudden changes in temperature. EM series (Common for all models) Step 1 Press the 【ON/OFF】 key to turn the power ON. The display shows “ - - - - - ” if there is something placed on the weighing pan or the scale is unstable. Step 2 Press the 【UNITS/MODE】 key to select “kg” ( kg mode ). Step 3 When the display doesn't show zero, press the 【RE-ZERO】 key. Step 4 When a tare ( container ) is used, place the container on the weighing pan and press the 【RE-ZERO】 key to set the display to zero. Scale weighing range = weighing capacity - tare weight Step 5 Place the object to be weighed on the weighing pan or in the container. Wait for the STABLE indicator to turn on and read the value. Step 6 Remove the objects from the weighing pan. Step 7 Press the 【ON/OFF】 key to turn the power OFF. When the auto power-off function is enabled, the scale turns off automatically after 5 minutes of stable condition and Error displayed. Display and symbols Step 1 Press the 【UNITS/MODE】 key to select “pcs”. Step 2 Press and hold the 【UNITS/MODE】 key to enter the sample unit weight storing mode. ( The figure on the left is the number of samples. ) Step 3 To change the number of samples, press the 【ON/OFF】 key. It may be set to 5, 10, 20, 50 or 100. Step 4 If necessary, place a container on the weighing pan and press the 【RE-ZERO】 key. Confirm that the right side of the number of samples shows zero. Step 5 Place the correct number of samples on the weighing pan or in the container. In this example, place 20 pieces of samples. Step 6 Confirm that the STABLE indicator is turned on. Press the 【UNITS/MODE】 key to calculate and store the unit weight. The scale is set to count object with this unit weight. The unit weight is stored in memory, even if the power is turned off. Note The total weight of samples should be more than shown below, regardless of the number of samples. Weighing capacity of 30 kg :100g, capacity of 60 kg :200g, capacity of 150 kg:500g If not, the display shows “ lo ut ” and returns to the display of step 5. Increase the number of samples (step 3) and try again. Turns on when the weight value is stable. Turns on when the scale shows zero. STABLE ZERO NET Turns on when the NET weight is displayed. ( The tare operation is in progress. ) HOLD Turns on when the scale hold the weight. Battery indicator Changes as the battery capacity decreases as shown to the left. Weighing units “kg”：Basic weighing mode in kg. “pcs” (pieces)：Counting mode which determines a unit weight (the weight of one piece) from the known pieces of samples and calculates how many pieces are on the weighing pan using the unit weight. / 1WMPD4002222C 1.1.
