4.1. Display Symbols and Switches Stable mark Unit Display hold mark Tare mark Unit Low battery mark Switches Display symbols Symbols Stable mark Tare mark Low battery mark Display hold mark Description This symbol appears when the displayed weight is stable. This symbol appears when tare operation is in progress. This symbol appears when the batteries are drained. Replace the batteries with four new type AA batteries. This symbol appears when the scale holds the weight on the display.
Buzzer switch On Off Selects whether to sound the buzzer or not. Sounds the buzzer when the scale is turned on or the scale holds the weight. Does not sound the buzzer. Note The settings of the Mode selection switch, Display direction switch and Buzzer switch become effective after the ON/OFF switch is turned off and then turned on again. 5. 5.1. BEFORE USE Preparation Procedure Spirit level 1 Use the accessory AC adapter or four type AA alkaline batteries.
5.1.2. Using the batteries CAUTION When installing the batteries, match the + (positive) and – (negative) terminals to those indicated in the battery compartment. Use four type AA batteries. Do not mix old and new batteries. Remove the batteries if the scale is not to be used for a long period of time. The batteries may leak and cause a malfunction. If the battery liquid spills on the body, wash the body part under running water immediately.
6. 6.1. USING THE SCALE Basic Weighing 1 Make sure that nothing is placed on the scale. 2 Press the ON/OFF switch to turn the scale on. All the display segments turn on and then the zero display appears. When the AC adapter is used, the display backlight turns on. 3 Press the ZERO switch. If the displayed value is not zero, press the ZERO switch. 4 Step on the scale gently and read the weight. The scale displays the weight. When the value is stable, the Stable mark turns on.
6.2. Weighing with a Tare In weighing with a tare, the scale stores the tare weight, turns on the tare mark and displays the net weight. The tare range is 3 kg to 150 kg. Net weight = Gross weight – Tare weight (Example of tare items: Clothes, plate and container) For weighing an object other than body weight, the scale mode, that does not hold the weight, is convenient. Nothing on the scale Procedure for weighing with a tare 1 Make sure that nothing is placed on the scale.
7. 7.1. CALIBRATION About Calibration Calibration is the function to adjust the scale so that it can weigh accurately. When the verification seal is broken, re- verification is required. CAL switch cover CAL switch Break the verification seal and locate the CAL switch cover on the scale bottom. Slide the CAL switch cover in the direction indicated by the arrow. The CAL switch is on the board inside. When pressing the CAL switch, do not use a sharp object such as a ballpoint pen.
6 Press the ZERO switch to adjust the temperature setting. When the Display direction switch is set to ↑, each time the ZERO switch is pressed, the number increases by 1. When the Display direction switch is set to ↓, each time the ZERO switch is pressed, the number decreases by 1.

The scale stores the new temperature setting at calibration and indicates [C-6]. 8 Press the ON/OFF switch.
of Thermo-sensitive resistor and moves to the next item [C-11]. When the ZERO switch in place of the ON/OFF switch is pressed, the scale moves to the next item [C-11] without storing the reference count for current output of Thermo-sensitive resistor. 14 With [C-11] on the display, press the ON/OFF switch. The display indicates [CAL0]. Stable mark 15 Make sure that nothing is placed on the scale and wait for the Stable mark to turn on. 16 Press the ON/OFF switch.
7.3. Adjusting the Gravitational Acceleration Adjust the gravitational acceleration to that of the installation site. When the scale is transported to a different area, the adjustment is required. Note The gravity values for various locations are listed on page 19. 1 Set the Mode [Personal]. selection switch to 2 While holding down the CAL switch, press and hold the ON/OFF switch for about 2 seconds. All of the display segments turn on. Release the switches after about 2 seconds.
8. 8.1. DATA COMMUNICATION RS-232C Serial Interface The AD-6121A scale has an RS-232C serial interface installed as standard. Using the optional RS-232C cable (AX-KO2238), the scale can send the data to external devices such as a personal computer. Interface specifications 8.1.1.
8.2. 8.2.1. Connecting to a Personal Computer Connection procedure The below is an example of connecting the scale to a Windows-based personal computer. Optional RS-232C cable AX-KO2238 1 Insert the optional RS-232C cable (AX-KO2238) into the LINE (External output terminal) jack located on the bottom of the scale. 2 Insert the D-Sub 9-pin connector of the RS-232C cable to the RS-232C port (COM1 port) located on the personal computer. 8.2.2.
9. 9.1. MAINTENANCE Maintaining the Performance Quality Check the scale regularly to make sure that it weighs correctly, and perform inspection or calibration as necessary. For details on inspection or calibration, contact the local A&D dealer. 9.2. Cleaning the Scale To clean the scale, use a soft cloth that is moistened with water and a mild detergent solution. After moistening, the cloth must be squeezed or rung out, so that it is not dripping wet.
10. BEFORE ASKING FOR REPAIR Before asking for repair, refer to the table below. When What to do Nothing appears on the display, even when the scale is turned on. [----] remains on the display and does not change. The difference between an estimated weight and the actual weight is large. The switches do not function. The display does not change even when the switches are pressed. [E-1] , [E-2] or [E-4] appears on the display. Check whether the AC adapter or batteries are installed correctly.
