If the DeltaRange is exceeded, the last decimal place blanks out. By pressing the bar again to tare, it is possible to again use the DeltaRange (de- scribed in the Paragraph entitled, 'Weighing-in"). Weighing-in (ASd 1 or 2) - Open the sliding glass door. - Fill in substance up to the desired target weight (to read the weight accurately, the door must be closed). If different components are to be weighed, one after the other, into the same container, it is possible to tare after each weighing and start the next weighing from zero (up to 60 g in the DeltaRange). This can be done until the tare container and all the components together reach the end of the weighing range: DeltoDisploy: GD hanger (for weighing below the balance) - Open all sliding glass doors. - Remove the weighing pan. - Place the balance on its back. - Loosen the screw on the bottom of the balance. - Swing the cover to one side. - Retighten the screw. A hook is visible in the opening; the object or sub- stance can be weighed by attaching a hanger from this hook. - Place the balance back on its feet, place the weigh- ing pan back on and level the balance. - With the hanger attached to the hook, press tare. Note: The weighing pan does not have to be placed back on if the hanger is at least as heavy as the pan. The hanger is not available from METTLER! DeltaDisplay I Preliminary steps Checking the operating voltage I The operating voltage setting must agree with your local power-line voltage; please check this setting and, if needed, change it. Admissible power-line voltage in the switch positions: 115V: 92V...132V 220V: 184V...265V Location - A stable location; as free from vibration as possible. - Make sure there are no large temperature fluctua- tions. - Avoid direct sunlight and drafts. - Connect the power cable at the work station. Installing the weighing pan and the windshield rinn. louolinn tho hnlnnf'o Care and maintenance Cleaning A cloth with some soapy water is sufficient to clean the weighing pan and housing. Do not use any strong solvents. To remove residues from the weighing cham- ber, use the small artisfs brush that is included in the balance standard equipment (do not blow air through the chamber). Replacing the micrafuse - Disconnect the power cable. - Turn out the fuse holder (in the power-line connec- ~on .sock.~t) ~ith 9 ~c!e~ ~d!iv~~ 'L ~ . ~ L ~. ~ ~~, The DeltaDisplay switches on automatically when weighing in substances quickly; the last two digits in the DeltaRange or the last digit in the coarse range are blanked out and the display change sequence speeds up. This allows the increase in weight to be followed better. When weighing in slowly towards the target weight, the two digits (Delta Range) or the last digit in the coarse range switch back on. The display change sequence remains rapid. Only when weight changes are very small does the balance switch back to the normal display change with the full number of decimal places.

Note: When the green dot lights up in the display, the data interface is blocked; when the green dot goes out (stability), the data interface is unblocked. DeltaRange: Order No. 38594 - Place weighing pan on balance; the conical peg centers the pan in the opening in the base of the weighing chamber. - The two leveling screws should be adjusted so that the bubble is in the middle of the circle. Whenever the location of the balance is changed, the balance should be releveled. Accessories Optional equipment - Windshield ring, can be stacked: 1 unit Weiahina ranae 205 n /1 mn Your AE260 has a coarse range from 0..,205 g; in this range, readability is 1 mg, The DeltaRange (fine range) turns your "milligram balance" into an "analytical balance", This means that the readability is increased to 0,1 mg in a range of 60 g (by pressing tare each time, it can be moved throughout the entire weighing range). Every time the fine range is exceeded, the last decimal goes out; you are then weighing in the coarse range. - Tweezers, 210 mm long (with plastic tips) 70209 - Density (specific gravity) determination kit 33340 - Foot pedal 46278 - Handkey 42500 - Microfuses, 160 mA slow-blowing (set of 3) 55144 - Data interfaces: 011 Option - CL/RS232C unidirectional 38750 012 Option - CL/RS232C bidirectional 38751 013 Option - IEEE488 38752 040 Data Output (unidirectional mode) 38795 Standard equipment - Power-line cable neutral 87576 Switzerland 87920 Germany 87925 USA 88668 - Weighing pan, 80 mm dia. 38590 - Centering disk (for windshield ring) 38609 - Hair-bristle brush 70114 - Windshield ring 38689 Specifications AE 260 DeltaRange 60 a DeltaRanae 200 a 0.1 mg 0...60 9 0...60~ 1 mg 0...205 9 0...205 9 0.1 mg 0.5 mg ::to.2 mg :t:1 mg 5 sec 1.5/3/6 sec 0.4 sec 0.2/0.4 sec Readability Weighing range Tare range (subtractive) Reproducibility (standard deviation) Linearity Stabilization time (typically) Integration time (adjustable) Display sequence - Mettler DeltaDisplay off - Mettler DeltaDisplay on Stability detector - Sensitivity selectable in three steps Sensitivity drift (lO...30°C) Calibration weight (built-in), adjusted to an 0 mg niml!n!:inn!: 1/2/off 100 g;ucfJustBt1to:fo:l'"mg lO...40°C 25...85% : Weighing pan (stainless steel) 80 mm dia.

Switching the display on/off - Briefly press the single control bar; all display seg- ments light up for several seconds: Orl Orl r:if CI Orl CI CI r:I , , , ,-., ..,.n , . .-'.-'.-. - Afterwards, the display automatically sets itself to zero. - Lightly lift the control bar; the display is switched off. Calibration I Make absolutely sure: The balance must be left connected to the power supply for at least 60 minutes before "calibrating", - Press and hold the single control bar until -CAL- appears in the display, then release control bar. The display changes to CAL , then to CAL 100 (blinks), - Move calibration lever all the way to the rear; the display changes to CAL , followed by 100,000, then to CAL a (blinks), - Move calibration lever all the way back towards the front of the balance; the display changes to , followed by zero, Measuring cycle/measuring accuracy By selecting a particular integration cycle, as well as a particular stability detection step, the balance can be canfigured according to your weighing location and needs. n egrQ'i\i5fi Time; Step 1: Used for very stable, vibration-free weighing table (short measuring cycle). Step 2: Normal setting. Step 3: Used for unfavorable ambient conditions (long measuring cycle). - Press the control bar and hold it until -Int- appears in the display, then release the control bar. - Immediately press the control bar briefly; the display will change to the next step. - Stop at the step you wish to use and wait for the dis- play to return to the weighing mode (zero). Stability detector: Step 1: Great sensitivity (long pause before data are released). Step 2: Less sensitivity (short pause before data are released). Normal setting. off The stability detector is switched off. Make sure Step: that when this is the case, DeltaDisplay is also switched off (described in Paragraph entitled, "Weighing-in"). - Press the control bar and hold until -ASd- appears in the display, then release control bar, - Immediately press control bar again briefly; the dis- play changes to the next step. - Stop at the step you wish to use and wait for the display returns to the weighing mode (zero). Note: After selecting the integration time, you can go directly to the selection of the stability detector setting by holding the control bar down. Taring - Open the sliding glass door. - Place a tare container on the weighing pan. - Close the sliding glass door. - Press the control bar briefly; the display changes to zero. Note: It is possible to carry out external taring by using the hand key or foot pedal from the "accessories, op- tionar (connection sockets on rear of balance).
