The meter is a portable instrument that measures and reports air contamination. It holds 500 samples in memory and records the date, time, counts, sample volume, temperature, and relative humidity of each sample. The data can be easily downloaded to a personal computer using the USB interface cable.

The meter is commonly used for the following:



 Monitoring clean-rooms, manufacturing processes and pharmaceutical



production.



 Indoor Air Quality (IAQ) monitoring.





 Monitoring gowning rooms.

USING THE METER

The following sections give detailed information about using the meter.

7-1 Setup

To set up the meter:

Go through the different screens and set the desired parameters for sampling. Refer to previous sections regarding the different screens and menus.

7-1-1 Setting the Counting mode:

The counting mode choices are: Concentration mode:

The Concentration mode is used to take a quick glimpse of airborne particle contamination levels. For example, this mode might be used in areas where particulate levels are unknown and may exceed the operating levels of the meter. The meter estimates the count per cubic foot or liter depending on the volume selected. This mode should not be substituted for full sampling.

Totalize mode:

In Totalize mode, the particle counts are display and accumulate as sampled. When the sample is complete, the record is stored and the value is displayed on the screen until the next sample is started.

Audio mode:

In Audio mode, the meter beeps once each time the alarm limit is exceeded. For example, if the limit is set to 10, the meter beeps when the count first reaches 10 and beeps again for every multiple of 10. In Audio mode, the display shows counts as in Totalize mode.

To set the counting mode:

1. Press screen is displayed with the current “Cnt Mode” field is selected.

MAINTENANCE

The Meter contains no user-serviceable parts. To avoid electric shock, injury, or damage to the meter, do not open the meter.

Use the zero count filter to ensure that the meter filter is free of contamination. Refer to “Purging the Meter”.

8-1 Cleaning the Case

Periodically wipe the case with a damp cloth and mild detergent.

To avoid damaging the meter, do not use abrasives or solvents to clean the meter case.

8-2 Charging the battery and using the AC adapter

Recharge the battery as soon as “LOW BATTERY” appears on the display.

The battery symbols on the display show the status of the battery:

++ The battery is in “Fast Charge” mode.

The ac adapter is connected and the battery is charging. When the battery is below 95 % of its charge, the meter uses “Fast Charge” mode to bring the battery back up to 95 %.

Warning

Caution

+ The battery is in “Trickle Charge” mode. Once 95 % of the

charge is attained, the meter switches to “Trickle Charge”

mode to charge the remaining 5 % of the battery. The battery is fully charged. The battery is partially charged.

The ac adapter is used to recharge the battery as well as power the meter. This feature allows the meter to be used while the battery is charging.

Page 23

connect the ac adapter:

1. Attach the power cord to the end of the ac adapter.

2. Plug the ac adapter into the 12V jack on the meter.

3. Plug the power cord into an ac outlet. The meter will take two hours to fully charge.

Note: If the Meter is powered off during charging (Trickle Charge mode),

the battery will require up to 27 hours for a full charge. To charge the battery in 2 hours, the meter must be turned on while charging (Fast Charge mode).

If the meter is charged while powered off (Trickle Charge mode) the battery symbol in the display will not update to show the actual charge status until the meter is turned on with the ac adapter plugged in for approximately five minutes.

8-3 Purging the Meter Sensor

Caution To avoid possible damage to the meter, avoid using the meter in an excessively dirty or dusty atmosphere.

Excessive particle intake can damage the meter. To purge the particle counter sensor:

1. Fit the adapter onto the end of the zero count filter.

Note the arrow on the filter denoting airflow direction.

2. Connect the adapter directly onto the end of the isokinetic probe.

3. Operate the unit for approximately 15 minutes.

4. On the average, not more than one particle greater than 0.3 µm in five

minutes or not more than one particle per 0.5 cubic foot should be apparent.

Once the unit is purged, resume normal use. Remove the zero count filter and adapter from the isokinetic probe.
