4-6-2 Long-term exposure measurements

Location

Place the meter between yourself and the suspected source of

radiation.  Make measurements at those points where parts of your
body are nearest to the source of radiation.

Note

 : Use the “Average ” or “Max average” modes only when the

instantaneous measurement values are fluctuating greatly.

You may fix the meter to a wooden or plastic tripod.

4-6-3 Alarm function

Use this feature in the “Instantaneous”, “Max. instantaneous”,
“Average” or “Max. average” modes.

When the measured value exceeds the limit value, a sequence of
warning beeps sounded.

4-7 Manual data memory storing individual measured values

The meter includes a non-volatile manual data memory function  which
can store a maximum of 99 measured values.

4-7-1 Storing individual measured values

Value stored indication

Current memory location
(Starting with memory to location 01)

The current memory location number appears in the lower right small display.

Once you press the ( 

 ) key, it will store a displayed value and

plus “one” for the memory location number.  Each flash of the “ 

  ”

symbol display  indicates one storage.  The memory location number

shows “ 

 ”, to indicate the manual data memory is full, then you must

clear the entire contents of the manual data memory before you store
any new values.
