2. 5 measurement modes:

1. Standard mode:
The counter measures the average negative ion count per 20 sec.

2. High speed mode:
The counter measures the average negative ion count per 10 sec. Good for quick measurement

3. Automatic measurement mode:
The counter measures the average negative ion count of 8 consecutive 20 second measurements. A thermal printer prints out the maximum/minimum/average negative ion count data as well as the 8 negative ion counts.

4. Moving average mode:
The counter measures the average of 16 negative ion counts collected during the first 20 seconds and those collected every second during the next 15 seconds. This mode provides more accurate negative ion count data. It takes 35 seconds to complete the measurement.

5. Radiation detection mode:
The reading increases depending on the dose of radiation the counter detects. The larger the dose is, the faster the reading increases. Good for finding the source of the radiation.

3.Measurement in progress:

1.Push the "POWER" button, and choose the mode to testing;

2.Push the "START" button to start measurement.
