Clear (reset) the totalizer. (Note1)
Press
If you have changed the count rate, clear (reset) the count before you start the
totalizer.
Start the totalizer. (Note1)
• Press
Check that "C" is shown on the display indicating that counting is in progress.
Note 1: The LF232 converter has the function to start/stop the totalizing operation or clear the
internal totalizer.
For details of how to operate the totalizer, see 7.3.4 "Totalizer Operation."
Note 2: Example of count rate setting range
Count rate can be set in the range of minimum value (3,600,000 pulses/h) to maximum
value (3.6 pulses/h) with respect to the set range
Example:
follows:
Minimum value: 3,600m
Maximum value: 3,600m
Note 3: Example of pulse width setting range (in the case of manual setting)
Pulse width can be set within the range of 0.3ms to 500ms in increments of 0.1ms.
However, the pulse width must be 40% or less of the full-scale period.
Example 1:
Since the count rate is 3,600 m
pulse/s), the full scale period is 1s ÷ 1000 = 1ms.
Therefore, pulse width can only be set to 1ms x 0.4 = 0.4ms.
Example 2:
Since the count rate is 3,600m
the full scale period is 1s ÷ 0.001 = 1000s.
Therefore, pulse width becomes 1000s × 0.4 = 400s.
However, since the maximum value is 500ms, pulse width becomes 500ms.
Example 3:
Since the count rate is 3,600m
full scale period is 1s ÷ 1 = 1s.
Therefore, pulse width becomes 1s × 0.4 = 400ms.
However, since the maximum value is 100ms, pulse width becomes 100ms.
