b) SAMPLE TIME – this indicates the interval at which SEARCH samples are taken.
Selections are:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 30, 40, 50 or 60 seconds.
Under most conditions, a 5 second sample gives reasonable accuracy however, a 1 second selection
is advisable if the unit is being used in a continuous search mode and numeric data is required.
NOTE: The Audio response is NOT affected by this time selection as it is updated at a fixed 20
times/second rate.
c) CHART RANGE
This sets the maximum vertical chart scale in counts for the “chart recorder” display.
Selections are: 64cps, 128, 256, 512, 1K, 2K, 4K, 8K, 16K, 32K, 64Kcps and
AUTO.
Some users prefer to have a fixed display so they can judge relative changes in the data while “chart
recording”. They can select the desired range from the above selections.
NOTE : If a fixed full scale value is set and exceeded the display will saturate at the top. Thus if you
set 1K (1000cps) then the chart display will have 0 at the bottom and 1000cps at the top. As long as
the radiation field stays BELOW 1000cps then the display is normal.
If the radiation field goes above 1000cps then it will reach the upper limit and stay there until the
radiation comes below 1000cps. The numeric data on the display are unaffected by these limits.
