(完整版)数字多用表直流电压表测量审核不确定度评定

数字多用表直流电压、交流电压、直流电阻测量结果的不确定度评定一、直流电压测量不确定度的评定1 概述1.1测量依据: JJF 1587-2016 数字多用表校准规范。

1.2测量环境条件: 环境温度20℃,相对温度60%。

1.3测量标准: 多功能标准源HG6501。

1.4 被测对象: 数字多用表FLUKE187,直流电压示值误差。

1.5 测量方法: 采用直接测量法,将多功能标准源HG6501电压输出端与数字多用表输入端连接直接测量。

将数字多用表电压示值与多功能标准源HG6501参考值相减,其差值即为数字多用表直流电压的示值误差。

2 数学模型n x V V -=∆式中: ∆—示值的绝对误差;x V —数字多用表FLUKE187示值; n V —多功能标准源HG6501参考值;3 不确定度传播律)()()(2222212n x c R u c R u c u +=∆ 灵敏系数 11=∂∆∂=x R c ,12-=∂∆∂=nR c 4 测量不确定度来源分析与标准不确定度分量的评定不确定度来源主要为被测仪器的测量重复性、所用标准器的误差、分辨力以及环境条件的影响等。

因校准时按照规范要求的环境条件进行,故其引入的不确定度分量可以忽略不计。

4.1多功能标准源HG6501引入的标准不确定度分量u 1:由多功能标准源HG6501技术指标得知,直流电压100mV 绝对不确定度为:读数×0.02%+0.02mV (k =2),因此校准100mV 时绝对不确定度为100mV ×0.02%+0.02mV =0.04 mV ,则标准不确定度u 1=0.023mV 同理可求得其它校准点引入的标准不确定度结果如下表:4.2被校数字多用表分辨力引入的标准不确定度分量u2:数字多用表FLUKE187在示值(100mV)时的分辨力为0.01mV, 半宽a=0. 005mV, 在区间可以认为服从均匀分布,包含因子k=3,则u2= 0. 005mV /3=0.0029 mV 同理可求得其它校准点分辨力引入的标准不确定度结果如下表:4.3被测仪器测量重复性引入的标准不确定度分量u A按照重复性测量要求对直流电压100mV点进行连续10次测量,结果如下表:主要来源是由数字多用表的测量重复性引起的。

校准
数表应当每年进行一次校准,以确保性能满足技术指标的要求。

在校准前,首先在数表后盖上(在附件支架)下找到校准按键,该按键位于校准标签的下面,如图5所示,小心地用校准工具刺破校准标签,按下校准按钮就可以启动校准。

图5. 校准按键的位置
按键接口
启动校准步骤时,将拨动开关置于DC mV位置,然后按住数表的校准按键一秒钟,此时数表进入如图6所示的校准模式,数表将保持在校准状态,直到拨动开关被置于OFF为止。

图6.校准显示
一般步骤
每个所要校准的功能都需要一系列的信号输入,在第二显示位置显示了下一步校准所需要的输入信号,主显示显示的是测量值,测量值与所施加的信号可能会有所不同,这是因为显示的是为校准的测量结果,校准的一般步骤如下:
1.将拨动开关置于你所要校准的功能。

2.按照第二显示的数字设置标准装置的输出。

3.等待一段时间直到主显示上的测量结果稳定。

4.按下UP按键进行下一个校准步骤,数表将记录新的校准因子。

5.重复步骤2至4,直到第二显示处出现End。

这表明该测量功能的校准步骤已经完成,在出现End之前,新的校准因子并不会被保存。

6.如果还有其它功能需要校准,将拨动开关置于响应的功能,然后从步骤1开始校准,否则,将拨动开关置于OFF位置以退出校准。

注意
DC mV校准对所有功能都会产生影响,而AC mV校准将影响所有交流测量功能。

如果校准器的输出与校准点的正常值相差超过15%,那么工厂默认校准常数将自动启用,以替代标准源的输出,此时,数表可能通不过校准测试,因此需要再校准。

特殊需求
DC mV校准会对所有测量功能产生影响,因此,DC mV的校准必须在其它功能校准前进行,同样的,AC mV的校准必须在其它AC功能校准之前进行。

在DC mV校准后,其它
功能的校准的次序可以随意。

温度校准只需要在更换以下元件后进行:U4 A/D芯片,U10 EEPROM或U100 基准节点传感器。

温度校准的过程如下:通过测量一个外部温度然后输入测量结果计算校准因子,然后把校准因子保存在校准存储器中,这个过程是通过串行接口进行的,细节请参阅“温度校准”章节。

当用户更换了U10 EEPROM,必须重新输入数表的序列号和型号,细节请参阅“重新对序列号或型号进行编程”章节。

远程接口
通过远程接口借助MET/CAL软件,用户可以进行半自动校准。

温度校准
所需设备:
● Fluke87/89-IV,187/189维护软件,Fluke P/N676152。

●红外串行电缆套件,Fluke P/N 1590638
●个人电脑
● Fluke80T-150U精度为±0.2℃
● Fluke 8060A 数字多用表
注意
以下的校准步骤只有在数表经过修理并更换了以下元件之一时才需要进行。

这些元件是:U4 A/D芯片,U10 EEPROM或U100 基准节点传感器。

设置
在开始校准前,将拨动开关置于OFF位置,让数表静置在恒温环境中30分钟,这可以使内部的基准节点传感器和输入插孔的稳定到同一温度。

将红外串行电缆连接到电脑的串行口,安装87/89-IV,187/189维护软件。

步骤
在拨动开关置于OFF位置时,将80T-150探头插入数表的COM插孔中(与基准节点的温度相同)。

确保探头与插孔紧密接触,测量并记录COM插孔的温度并以1/100℃为单位记
录此时的测量值,不要把这个温度装换位华氏温度,即使是数表正在使用华氏刻度作为显示输出。

将拨动开关置于温度位置,不管数表是否出于校准模式,在维护软件的菜单中,点击℃Ref. Junction。

在下一个文本框中输入温度值,然后点击OK,此时计算机通过红外串行电缆将基准节点的温度值传送到数表中。

尽管温度校准并未结束,但是此时将关闭数表电源是安全的,这样做的结果会使先前的步骤失效。

要完成温度校准,必须对DC mV功能进行校准。

在DC mV校准完成后:
1.将拨动开关转换到温度位置,按下数表后盖上的校准按钮使数表进入校准模式。

在通常用来显示所需输入值得第二显示上,出现zero字样,此时,不需要任何输入。

2.按下UP按键
此时所计算的温度修正系数被保存到EEPROM中,并结束温度校准。

3.对其它功能进行校准或将拨动开关置于OFF位置退出校准。

重新对序列号或型号进行编程
当更换了U10EEPROM后,用户必须重新输入数表的序列号和型号,如下进行操作:
1.将红外串行电缆连接到电脑,安装87/89-IV,187/189维护软件(Fluke P/N 676152)。

2.将数表的拨动开关置于任何一个功能。

3.在维护软件的菜单中,点击EEPROM,再文本框中输入序列号点击OK,输入数表型号时,在型号菜单对话框中点击Yes或No。
