3 Operation
The guidelines in this chapter describe how to use the Digilert 100.
Units of Measurement
The Digilert 100 is designed both for users of conventional units (milliroentgens per hour and counts per minute) and for users of SI units (microsieverts per
hour and counts per second).To switch between conventional and SI units,use the Utility Menu.See "The Utility Menu" in this chapter.
Starting the Digilert 100
Be sure that a standard 9-volt alkaline battery is installed in the battery compartment in the lower rear of the Digilert 100.Note:When installing the battery,place the battery wires along the side of the battery and not under it.
To start the Digilert 100,set the top switch to the mode you want,and set the bottom switch to On or Audio.The Digilert 100 then does a four-second system check,displaying all the indicators and numbers.
After the system check,the radiation level is displayed in the selected mode.One minute after you start the Digilert 100,a short beep indicates that enough information has been collected to ensure statistical validity.
Operating Modes
When the mode switch is set to mR/hr or CPM,the numeric display is updated every three seconds.At low count rates,significant changes in the radiation
level displayed can take up to one minute to stabilize.See "Operating Ranges and Response Times" in this chapter for more information.
CPM (or CPS) and timed total counts are the most direct methods of measurement; mR/hr (or μSv/hr) is calculated using a conversion factor
optimized for Cesium-137,so this mode is less accurate for other radionuclides,unless you have calibrated the Digilert 100 for a specific radionuclide using an appropriate source.It is more appropriate to measure alpha and beta activity
using CPM than using mR/hr.Conversion for alpha and beta emitters is calculated differently,and the Digilert 100's reading in mR/hr may not be accurate.
The most immediate indicators of the radiation level are the count light,the audio beep,and the alert.It takes three seconds before an increase is shown on the numeric display in the dose rate modes.

3操作
该准则在本章描述了如何使用Digilert 100 .
计量单位
该Digilert 100的目的是为用户的常规单位( milliroentgens每小时每分钟)和用户的SI单位( microsieverts每
小时数每秒) .之间切换常规和SI单位,使用工具菜单.见“实用菜单”这一章.
启动Digilert 100
确定一个标准9伏碱性电池是安装在电池在较低的后部Digilert 100 .注意:当安装电池,电池的电线发生一起在电池的一侧,而不是根据它.
要启动Digilert 100 ,设置顶端切换到您想要的模式,并设置底部开关或音频.该Digilert 100然后做了4次系统检查,显示所有指标和数字.
经过系统检查,辐射水平显示在选定的模式.一分钟后启动Digilert 100 ,短蜂鸣表明,足够的信息已经收集,以确保统计的有效性.
操作模式
当模式开关设置为先生/小时或每千次展示的是最新的数字显示每3秒钟.计数率低,显着变化辐射
级别显示最多可能需要一分钟,以稳定.见“经营范围和响应时间”这一章以获取更多信息.
每千次展示成本(或郊野公园段)和总时间的罪状是最直接的方法测量;先生/小时(或μSv /小时)计算时使用的转换因子
优化的铯-137 ,所以此模式是不太准确的其他放射性核素,除非您已校准的Digilert 100特定核素使用一个适当的来源.这是比较恰当的措施,α和β活动
使用每千次展示成本比使用先生/小时.转换为α和β排放的计算方法不同,以及Digilert 100的读先生/小时可能不准确.
最直接的指标的辐射水平是伯爵轻,音频响铃,一个增加上显示的数字显示在剂量率模式.
