1. Secondary function C is to act as a clear key when setting values for parameters or other functions Print or To print the results to a PC or printer using the optional RS 232 interface It also adds the value to the accumulation memory if the accumulation function is not automatic Secondary function ESC is to return to normal operation when the scale is in a parameter setting mode U or UNIT This key will select either kilograms pounds ounce for the weighing unit 3 OPERATION 3 1 ZEROING THE DISPLAY You can press the ZERO key at any time to set the zero point from which all other weighing and counting is measured within 4 of power up zero This will usually only be necessary when the platform is empty When the zero point is obtained the display will show the indicator for zero The scale has an automatic rezeroing function to account for minor drifting or accumulation of material on the platform However you may need to press the ZERO key to rezero the scale if small amounts of weight are shown when the platform is empty 2 3 2 TARING Zero the scale by pressing the ZERO key if necessary The zero indicator will be on Place a container on the platform weight value will be displayed Press the TARE key to tare the scale The weight that was displayed is stored as the tare value and that value is subtracted from the display leaving zero on the display The NET indicator will be on As product is added2. the Low Limit NOTE The weight must be bigger than 20 scale divisions for the checkweighing to operate To disable the Check Weighing function enter zero into both limits by pressing the FUNC key when the current limits are shown then pressing the ZERO key to store the zero values Note you can set high low limit in all normal weighing percentage weighing and counting mode 5 3 7 ACCUMULATED TOTAL The scale can be set to accumulate automatically when a weight is added to he scale or manually by pressing the PRINT key See the PARAMETERS Section in technical manual for details of selecting the method The accumulation function is only available when weighing It is disabled during percent weighing or parts counting 3 8 MANUAL ACCUMULATION When the scale is set to manual accumulation the weight displayed will be stored in memory when the PRINT key is pressed and the weight is stable The display will show acc 1 and then the total in memory for 2 seconds before returning to normal If the optional RS 232 interface is installed the weight will be output to a printer or PC Remove the weight allowing the scale to return to zero and put a second weight on Press PRINT the display will show acc 2 and then show the new total Continue until all weights have been added To view the totals in memory press the PRINT key when the scale is at zero The display will show the total number of items acc xx and the total weight before
3. the battery To charge the battery simply plug into the mains power The scale does not need to be turned on The battery should be charged for 12 hours for full capacity Just under the display CTG is an LED to indicate the status of battery charging When the scale is plugged into the mains power the internal battery will be charged If the LED is green the battery has a full charge If it is Red the battery is nearly discharged and yellow indicates the battery is being charged As the battery is used it may fail to hold a full charge If the battery life becomes unacceptable then contact your distributor 5 CALIBRATION To start calibration turn the scale off and then turn it back on Press the Tare and keys together during the initial counting from 9 to O on the display The display will show unLoAd Remove all weight from the pan and then press the ZERO key to set the initial zero point 7 Then use Limit and Tare key to key in calibrate weight press ZERO key to sure display shows load put this weight on platter after stable indicator on press ZERO key to sure After selfchecking again scale is ready for you

6. only the weight of the product will be shown The scale could be tared a second time if another type of product was to be added to the first one Again only the weight that is added after taring will be displayed When the container is removed a negative value will be shown If the scale was tared just before removing the container this value is the gross weight of the container plus all product that was removed The zero indicator will also be on because the platform is back to the same condition it was when the ZERO key was last pressed 3 3 WEIGHING A SAMPLE To determine the weight of a sample first tare the empty container then place the sample in the container The display will show the weight and the units of weight currently in use 3 4 PERCENT WEIGHING The scale will allow a sample weight to be shown as 100 Then any other weight placed on the scale will be displayed as a percentage of the original sample For example is 350g is placed on the scale and the Yo key is pressed the display will show 100 00 Removing the 350g weight and putting a 300g weight on the scale the display will show 85 71 as 300g is 85 71 of 3509 Note the scale may jump by large numbers unexpectedly if small weights are used to set the 100 level For example if only 23 5g is on a scale with 0 5g increments and the scale is set to 100 the display will show 100 00 however a small change of weight will cause the display to jump to 102 13 as one scale di
