3.0    定义  Definitions:    Nil
别离的近义词4.0责任  Responsibility:
分析天平的操作与校验由检验员负责。
            The responsibility of operation and to verify the performance check of Analytical balances lies with QC .Analyst.
5.0    程序  Procedure:   
5.1操作  Operation:
5.1.1 观察水平仪的气泡是否处于中心确认天平是否处于水平。如果没有,通过调节天平后方的地脚螺钉直至气泡处于中心位置。
Ensure that the balance is leveled by obrving the air bubble is in the center of level indi
cator.  If not adjust the leveling by turning foot screws at the rear side of the balance housing until the bubble is in the center of the level indictor.
5.1.2打开天平电源开关。
Switch ‘ON’ the main switch of the balance.
5.1.3按“ON/OFF”键。
Press “ON/OFF” key.
5.1.4等30秒天平初始化后,天平显示‘0.00000’ g。否则按‘→ 0 ←’键。
Wait for about 30 conds for the initialization of the balance. After initialization the balance displays ‘0.00000’ g . Otherwi, press ‘→ 0 ←’ key
5.1.5当天平显示’0.00000’ 时,可以对天平开始操作。
When ’0.00000’ is displayed, the balance is ready for operation.
5.1.6将称量纸或称量瓶置于称量盘中心,关上天平玻璃门。
Place the empty container / butter paper on the center of the pan and clo the sliding glass doors.
5.1.7等读数稳定。
Wait till the balance shows stable reading.
5.1.8按‘→T ←’键清零,显示变为 ‘0.00000’ g 。称量纸或称量瓶的重量被去皮重了。
Tare the weight by pressing ‘→T ←’ key briefly. The display changes to ‘0.00000’ g. Now the weight of the container /paper is tared.
5.1.9 加入称量样品达到规定量。 
Add weighing sample to the container / paper till the required weight is displayed.
5.1.10等读数稳定。记录数据为总重量g。
Wait until the balance shows stable reading. Record the weight as “Gross Wt in g”.
5.1.11小心将样品移入量瓶后,将称量纸或称量瓶小心放置在称量盘中。
Transfer the sample carefully into the flask and place the butter paper or weighing object on the pan carefully. 骨折后注意事项
5.1.12关上天平玻璃门等读数稳定,记录数据为皮重g。
Clo the doors and wait till the balance shows stable reading. Record the weight as “Tare Wt in g”.
5.1.13称量mg样品,按天平右边的 ‘F’键。显示变为‘ ‘0.00’ mg,接着按照5.1.6步骤进行称量。
To weigh the sample in ‘mg’, press ‘F’ key in the right side of the balance .  The display converts into  ‘0.00’ mg  and continue from step 5.1.6 for to weigh.
5.2    提示  Precautions:
5.2.1  天平必须避免振动、风吹、高温、高湿。                                                                                                                           
The balance should be free from vibration, air thrust, strong heat and moisture.
5.2.2AG245天平称量范围不得超过200g。
Do not weigh beyond the weighing 200g on AG245 balance for the analytical work.
5.2.3 读数稳定后再确认数据。
Consider weight readings of the obrvations till constant reading is displayed.
5.2.4称量之前确保称量盘是干净的。用软毛刷清洁称量盘。
Ensure the pan is cleaned before weighing .Clean the pan with soft brush.
5.3校验    Performance check
5.3.1分析天平的日校验                                                                                                         
                        Daily Performance check Analytical Balance
5.3.1.1去除称量盘负载,清洁称量盘及其周围。
Remove any load from the weighing pan, clean the pan and area.
5.3.1.2持续按右上角的“Cal”键至显示“Calibration Internal”。
Press “Cal” key at the right top for a while to perform “Calibration Internal”.
5.3.1.3天平显示自校:开始显示+ 200.00000g 结束显示0.00000g 。      Balance shows calibration internal, then  + 200.00000g and finally 0.00000g.
5.3.1.4将10mg标准砝码置于称量盘中央,记录读数。 干锅鸭
Place 10 mg standard weight at the center of the pan and record the display reading.
5.3.1.5将100mg标准砝码置于称量盘中央,等显示稳定记录读数。
Place 100 mg standard weight at the center of the pan and record the display reading till
constant reading is displayed.
5.3.1.6将200g砝码置于称量盘中央,将读数记录在天平校验记录里。
Place the weight 200 g at the center of the pan and record the obrved reading in    Performance check Record of Analytical Balance.
5.3.1.7将校验细节记录在如附录I所示分析天平校验记录里。
Record the Performance check details in the Performance check Record of  Analytical Balance as shown in Annexure - I.
5.3.2 月校验(多个标准砝码)
