34 BM series8.5. Calibration Using An External WeightThis function calibrates the balance using an external weight.1 Connect the AC adapter and warm up the balance for atleast one hour with nothing on the weighing pan.2 Press and hold the CAL key until Calout isdisplayed, then release the key.3 When displaying Cal 0 , proceed as follows:If you want to change the calibration mass, pressthe RANGE key and proceed to step 4.If you use the calibration mass value stored inthe balance, proceed to step 5.4 Specify the calibration mass value as follows:RANGE key..........The key to switch blinking figures.RE-ZERO (+)key.....The keys to select the calibration mass oradjust the mass value. Refer to page 31.PRINT key............The key to store the new mass value.Even if the AC adapter is removed, thedata is maintained in non-volatile memory.CAL key ...............The key to cancel the operation andreturn to Cal 0 .5 Confirm that there is nothing on the pan and press thePRINT key. The balance measures the zero point.Do not allow vibration or drafts to affect the balance.The balance displays the calibration mass value.6 Place the displayed calibration weight on the pan and pressthe PRINT key. The balance measures the calibration mass.Do not allow vibration or drafts to affect the balance.7 end is displayed.Remove the weight from the pan.8 If GLP output is set, glp is displayed and the calibrationreport is output and stored. Refer to "GLP output (info)" and"Data memory (data)" of the function table, "11.2. GLPReport" and "12. Data Memory".9 The balance will automatically return to the weighing mode.10 Place the calibration weight on the pan and confirm that thevalue displayed is correct. If it is not within the range, checkthe ambient conditions such as breeze and vibration alsocheck the weighing pan.
