KEY DESCRIPTIONS These keys are used to manually enter a value for tare weights unit weight and sample size A secondary function is to enter alpha numeric characters for PLU descriptions etc Pressing this key clears the unit weight or an erroneous entry lt also clears the memory accumulation when the total is displayed This key is used to add the current count to the accumulator It also recalls the memory when pressed with no load on the scale Up to 99 values or full capacity of the weight display can be added Also prints the displayed values when Auto print is switched off or te This is used to enter the number of items of a sample Mi M5 To store and recall the Piece Look Up sample information U WiJUnis or This key is used to enter the weight of a sample manually It will also change the weighing units when other units are enabled PST or To set the upper limit for the number of items counted When this upper limit is exceeded the scale will sound the beeper A secondary function is to use it for the backlight control setting LocalRem or A JC counting scales operation manual This key is used to select the local or remote scale Tare or ST tares the scale by storing the current weight in the memory as a tare value subtracting the tare value from the total weight and displaying the results as a net weight Zero or gt 06 sets the zero point for all subsequent weighing by setting the displ2. repeat the calibration again 7 BATTERY OPERATION e The scales can be operated from the battery if desired The battery life is approximately 70 hours if only the basic unit is used If a second platform is used the battery life will be reduced e When the battery needs charging the arrow above the low battery symbol under the Weight display will turn on The battery should be charged as soon as the arrow above the symbol is on The scale will still operate for about 10 hours after which it will automatically switch off to protect the battery e To charge the battery simply plug into the mains power The scale need not to be turned on e The battery should be charged for 12 hours for full capacity e Just near the level bubble is an LED to indicate the status of battery charging When the scale is plugged into the main 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 nearly charged NOTE It is recommended that the battery be charged before using the scale when the unit has been unpacked 17 JC counting scales operation manual tare weight depending on the scale resolution For example in this case 1 45 would be used as the tare value e If a PLU number is recalled that does not have any information stored against it the scale will continue to work with Tare and Unit weight unchanged PLU s can b
