The Ports
There are two ports on the left side of the Digilert 100.
The calibration input port (2) is used for calibrating electronically using a pulse
generator. For more information, see "Calibrating Electronically" in Chapter 5.
The output port (3) below the calibration input port allows you to interface the
Digilert 100 to a computer, data logger, or other device using a 3.5 mm stereo
plug. For more information, see "Interfacing to an External Device" in Chapter
3.
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.
