! Use only original Sartorius AC adapters: – for Asia: – for the U.S.: 400081.1 400314.1 Connecting the Balance/Scale to AC Power § Insert plug into the jack (located on back of the balance/scale) § Plug the AC adapter into an electrical outlet ! LISTED power supply 11 V–21 V compliant with NEC Class 2 output. Below-Balance/Scale Weighing A port for a below-balance/scale weighing hanger is located on the bottom of the balance/scale. § Open the cover plate on the bottom of the balance/scale.
Using a Non-Rechargeable/Rechargeable Battery (not for model ELT103, GD502) $ A non-rechargeable or rechargeable battery is not included with the equipment supplied. ! Use only a commercially available non-rechargeable (8+ AA/Mignon) or rechargeable battery. ! When using a rechargeable battery, be sure to recharge it outside the balance/scale using a separate charger.
Leveling the Balance/Scale § Always level the balance/scale again any time after it has been moved to a different location. Example: moving bubble from R to L § Turn the feet as shown in the diagram until the air bubble is centered within the circle of the level indicator. > In most cases this will require several adjustment steps.
Operation Basic Weighing Function Features – Zeroing the balance/scale You can zero the balance/scale within the entire weighing range, up to the maximum capacity. Preparation § Switch on the balance/scale: press the e key § If necessary, zero the balance/scale: press the w key $ If necessary, change the configuration settings: see the chapter entitled “Configuration” $ If desired, load the factory settings: see the chapter entitled “Configuration,” menu item 9.
Application Programs Toggling between Weight Units With this application program you can toggle the display of a weight value back and forth between two weight units (see table below). Example: Toggle weight unit from pounds [lb] (application) to grams [g] (basic unit) Step Key (or instruction) 1. Select application program w > 2 sec 2. Select Toggling between Weight Units v 3. Confirm unit 4. Select weight unit; in this example: “5. Pounds” (see table below) 5.
Counting Purpose With the Counting program you can determine the number of parts or items by weighing. Example: Determine the number of uncounted parts; weigh in the selectable reference sample quantity (in this example: 20) Step Key (or instruction) 1. Select application program w > 2 sec 2. Select Counting v repeatedly 3. Confirm setting Symbol “ ” on the display: application is active Display Enter CF 4. Place empty container on the balance/scale 5. Zero the balance/scale w 6.
Weighing in Percent Purpose This application program allows you to obtain weight readouts in percent which are in proportion to a reference weight. Example: Determine an unknown percentage; store the weight on the balance/scale as the reference percentage (100%) Step Key (or instruction) 1. Select application program w > 2 sec 2. Select Weighing in Percent v repeatedly 3. Confirm setting Symbol “ ” on the display: application is active Enter CF 4. Place empty container on the balance/scale 5.
“Hold” Display Purpose The last stable value remains displayed for 5 seconds after removing the sample from the pan. Example: Determine weight of oversized sample Step Key (or instruction) 1. Select application program w > 2 sec 2. Select Display Hold (“HLdon”) v repeatedly 3. Confirm setting Symbol “ ” on the display: application is active 4. If necessary: zero the balance/scale Display Enter CF w 5. Place sample on balance/scale 6.
Totalizing Purpose With this application program you can add up successive weight values exceeding the capacity of the balance/scale. Example: Totalizing weight values Step Key (or instruction) 1. Select application program w > 2 sec 2. Select Totalizing v repeatedly 3. Confirm setting Symbol “ ” on the display: application is active 4. If necessary: zero the balance/scale Enter CF w 5. Place sample on balance/scale (in this example, 380 g) 6. Store value in memory.
Specific Gravity Purpose Use this application program to determine the specific gravity of a sample. The result is displayed with one decimal place. Beaker and wire not included with balance/scale. Example: Determine the specific gravity of a solid. Step Key (or instruction) 1. Select application program w > 2 sec 2. Select Specific Gravity v repeatedly 3. Confirm setting Symbol “ ” on the display: application is active Enter CF 4. If necessary, zero the balance/scale w 5.
Calibration/Span Adjustment Calibration is recommended after initial installation and each time the balance/scale is moved. Features Calibration/adjustment can be performed only when: – there is no load on the balance/scale, – the balance/scale is zeroed, and – the internal signal is stable. If these conditions are not met, an error message is displayed. The weight required for calibration/ span adjustment is displayed.
Configuration (Setup Menu) To configure the balance/scale; i.e., adapt the balance/scale to individual requirements. Step Key (or instruction) 1. Switch off the balance/scale e 2.
Error Codes Error codes are shown on the main display for approx. 2 seconds. The program then returns automatically to the previous mode. Display/Problem No segments appear on the display oL UL disErr calErr appErr PrtErr Bal.Err Sys.Err Max.
