1.0 INTRODUCTION ADK Series includes high capacity electronic balances. This series offers high-quality and precision balances that delivers accurate results. This manual covers models ADK-10 and ADK-20. This series of balances is the product of years of research, design, development and in-field testing. Every care has been taken during the manufacturing process of these durable balances to ensure that they will perform accurately and reliably for many years.
3.0 INSTALLATION 3.1 UNPACKING YOUR BALANCE Remove the balance from the carton carefully. It is recommended to keep the packaging materials for storing or transporting again, if necessary. In the carton you should find this balance together with: 3.2 Pan Pan support A spare fuse (0.5) A plastic plug A power supply cord This instruction manual LOCATING THE BALANCE • The scales should not be placed in a location that will reduce the accuracy. • Avoid extremes of temperature.
3.3 SETTING UP THE BALANCE • The ADK Series comes with a stainless steel platform packed separately. • Level the balance by adjusting the four feet. The balance should be adjusted such that the bubble in the spirit level located on the top of the base, is in the centre of the level. • Place the platform in the locating holes on the top cover. • Do not press with excessive force as this could damage the load cell inside. • Place the pan on top of the pan support.
3.4 SHIPPING PROTECTION This ADK balance has protection for the weighing mechanism that must be removed before the balance is used. • To remove the shipping protection, remove the pan then place the balance on the table upside down. Shipping Protection • Remove the cover over the protection screw by loosening 2 screws. Weigh below Attachment ADK BALANCE • Remove the protection screw, place in a safe place in case it is needed for shipping the balance again. Replace the cover. 3.
4.0 KEYPAD Keys Functions [On/Off] To switch on and off the balance display [Print] To send and receive data over RS-232 interface Also used to decrease the value during setting up the parameters [Cal] To calibrate the balance [Mode] To select the modes and units Also used to increase the value during the setting up the parameters [Tare] To Tare the balance.
5.0 OPERATING THE BALANCE 5.1 • To get the most from the balance, it should be warmed up for at least one hour and calibrate before using. • Don't use sharp articles (such as a pencil) to touch the keys. Use your finger only. • Always place samples to be weighed on the pan gently. Never drop them on the pan. • To weigh a magnetic material, a shield should be put on the pan to keep the magnetic material 3-5cm away from the pan or you can use the below pan weighing facility for such purpose.
5.2 • Press [Tare] again and wait for few seconds. Display will show “CAL - - F” • Place the suggested calibration mass on the pan gently (Take ADK-20 for example). Allow a few seconds for stability. • Press [Tare] again. • It will show “CAL End” and then “20000.0” will be displayed. • Remove the mass from the pan gently. • Display will show “0.0”. The balance is now in the weighing mode. • Note: if “CAL -no” is displayed during calibration, it means that the calibration has failed.
standard repeat the calibration procedure. • 5.3 If it still displays “CAL -no” send the balance to the service centre. CHANGING CALIBRATION MASS VALUE If you do not have the accurate calibration mass, you can change the value of the calibration mass by using the following procedure. This will enable to carry out the calibration of your balance accurately in absence of the proper calibration mass. Procedure • Turn the balance on by pressing [On/off] with the pan empty. • Press the [Cal] key.
6.0 WEIGHING 6.1 6.2 SIMPLE WEIGHING • Make sure nothing is on the pan. • Place a sample on to the centre of the pan gently when "0.0g" is displayed. • Record the weight displayed when the arrow appears on Stab to indicate that the reading is stable. • Remove the sample. • When a container is to be used, the weight can be tared. Place an empty container on to the pan. The weight of the container will be displayed. Press the [Tare] key to cancel the weight, “0.0g" will be displayed.
6.3 WEIGHING-OUT To remove a certain amount of material from a full container 6.4 • Place a container with sample in it onto the pan. The weight of all things on the pan will be displayed. • Press [Tare] to cancel the weight, "0.0g" will be displayed. • Take material out of the container. • The negative weight of the sample taken out will be shown. • Stop when the target is reached. DEVIATION WEIGHING To measure the difference between a reference weight and an unknown weight 6.
PREPARATION • Under the balance you will find a cover with two screws on it. • Remove the cover by unscrewing the two screws, you will find a post for installing the underhook. • Fasten the underhook to the weighing mechanism. • Hang a wire through the hole. • Place the balance on a table with a hole in it or on a stand specially designed for under-hook weighing, and let the wire hang through the hole.
8.1 PARTS COUNTING • Select the Counting mode by pressing [Mode]. It will display “0.”. • Press [Cal]. It will display “-10-“. You may change the sample size upwards by pressing the [Print] key or downwards by pressing [Mode]. The available options which are 5, 10, 15, 20, 25, 30, 35 and 40. • Place 10 (or the selected number) samples on the pan and press [Tare]. The display will show “10.” or the selected sample size. • Remove the samples from the pan. It will display “0.
8.3 ANIMAL WEIGHING It is difficult to weigh living animals accurately such as rabbit, which may move around a lot during weighing. The movement will not allow the display to show a stable weight and hence the true weight of the animal can not be determined. To overcome this problem, ADK series of balances are designed to offer animal weighing mode. The balance works out an average weight based on the force exerted by the animal over an extended period of time.
• Display check mode will be on showing all segments. Press [Print] when the display check mode is on. • Press [Mode] to scroll through the parameters from C1 to C7 and press [Print] to set a new value for a parameter. • Press [On/Off] to store the new settings. Display will be switched off. • Your balance will work with the new parameter settings when you turn on the display again by pressing [On/Off]. Parameter C1 Description No.
10.0 RS-232C INTERFACE This RS-232 supplied in the ADK balances is compatible with most of the standard RS-232 interfaces as found on printers and PC’s. 10.1 RS-232C SPECIFICATIONS Transmission form Data Format Data output mode Output data format Full duplex, Asynchronous transmission, Bi-directional Baud rate : 1200, 2400, 4800, 9600 Data bits: 8 bits Parity: None Stop bit: 1 bit Code: ASCII Auto print, press the [Print] key, command ST, +010.000xx g US, +010.
