3.1 Getting Started
3.1.1 Daily Zero Check
Before starting to use the CPC, zero check must be performed to confirm that the instrument is
operating properly. This zero check must be performed at least once a day, or before use if not used
daily.
1. Turn on the instrument, and wait for it to warm-up (requires approximately 600 seconds).
2. Attach the supplied zero filter.
3. The particle number concentration will become zero in approximately 10 seconds. Leave the zero
filter attached to the instrument for approximately 30 seconds in order to confirm that the zero
reading is stable.
4. Remove the zero filter, and the instrument will be ready for operation.
If the reading of the instrument does not become zero, please refer to
Caution
6. Trouble Shooting (page 32).
