1. You must cut off power supply of indicator before pulling out connecting line of load cell 7 7 During operation if trouble occurs operator must pull off the power supply plug immediately and user should return this indicator to our company for repair Non weighing manufacturer should not repair it or by yourself otherwise further destruction may happen 7 8 The storage is not granted the free repair guarantee because it is easily exhausted products In order to prolong using life please charge the cell fully before using it If you don t use the indicator for a long time you must charge the cell every two month and for eight hours each charging time Moving or installation must be carefully taken and must avoid strong vibration impact and bump in order to protect the storage cell from being damaged 7 9 From invoice date the indicator has a one year free repair period If any non artificially obstacle about the indicator happens under correct using conditions within this period the user is allowed to send the product with its guarantee card of the correct number back to our corporation for free repair The indicator shouldn t be taken apart otherwise free guarantee will be cancelled2. 11 indicator will display the weight of loaded weight Input the actual weight of 3000 m loaded weight Press to step 13 if the inputted Eg 3000 weight is as same as the loaded weight 12 Press three times to change the value to 3 and then press for confirmation bt Baud rate Indicator displays the 13 original baud rate parameter which can be updated by operator 14 Calibration is over exit to weighing mode ERRORO ERROR1 ERROR2 ERROR 3 HHHHHH LLLLLLL Chapter 5 Error Indication The zero inner code is over 260000 when calibration The loaded inner code is less load cell capacity is more The loaded inner code is more load cell capacity is less Calibration exceeding The zero lever is too high or load on the platform The zero lever is to high or no pan on the platform Chapter 6 Chargeable Battery 6 1 Turing on the AC power the indicator will charge the battery automatically So if you don t use battery frequently you should take battery out Note red end is black end is Wrong connection will destroy indicator Note The built in battery should be fully charged before it is used for the first time 6 2 Only when you turn off the AC power and push start key battery works Displaying LouoL means the insufficient of voltage it needs charge 6 3 When you use the battery first time you should charge the batter
