The subsequent sections tell you about Product
operation.
Power On/Off
Push to turn-on and turn-off the Product.
When the Product is turned on, a splash screen shows,
followed by the default sample screen.
You can start to collect samples immediately from the
sample screen. The samples use the default or stored
sample setup values that you can configure.
Before you use the Product, make sure the battery is fully
charged. See “The Battery” section.
Product Test
Electrical noise, sensor leakage, or other interference can
cause the Product to give incorrect data.
To check operation:
1. Attach the Zero-Count Filter.
2. In the Data Display Setup screen, enable the 0.3 μm
channel and set Concentration mode to COUNTS.
3. In the Sample Setup screen:
1. Set the sample time to 5 minutes
2. Set the hold time to 00:00:00
3. Set the delay time to 00:00:03
4. Set the MODE to Automatic
5. Set the number of CYCLES = 2.
4. Start the Product sampling and let it complete the 2 x
5 minute samples.
5. Examine the particle counts from the sample. Counts
must align with these specifications for instrument
operation to be verified:
No more than 1 particle >0.3 μm in 5 minutes
How to Purge the Product Sensor
Particles must be purged (removed) from the Product
sensor before use in a clean room or clean environment,
and after each high-sampling count. To purge the sensor:
1. Attach the adapter and the Zero-Count Filter.
2. Set the Product to sample continuously (set the
Count Mode to Cumulative.)
3. Start the count procedure. Continue the count
procedure until there are no new counts.
4. Remove the Zero-Count Filter for normal operation.
