Setting Logging and Viewing Run Time

5. To return to the Start screen , repeatedly press On/Off/Esc .

Setting Logging and Viewing Run Time

With the logging screen, you select the logging interval (i.e., 1 min. data logging), the averaging parameter (i.e., a type of data filter) and which parameters will be logged and stored into memory. An optional field, Run Time, allows you to view the amount of remaining log time when logged parameters are selected.

For logging, there are two selectable fields- the logging interval rate and the measurement averaging.

Log intervals

Log interval

Averaging

Explanation

This sets the log interval between specific data points. For example, if logging is set to 5 second intervals, then all parameter values are logged every 5 seconds. The logging parameters options are as follows: 1 second,5 seconds,

15 seconds, 30 seconds, 1 minute, 5 minutes, 10 minutes, 15 minutes, and 30 minutes, and 60 minutes.

The Averaging parameter is used to average all measurements displayed on the screen. If averaging is set to 15 then the last 15 measurements are averaged. (New measurements are updated every second.) This averaged value is displayed on the monitor. It’s basically a data filter. The averaged data will change less rapidly than the 1 second data since it is averaged. The user options are 1 – 30 with increments by 1 interval.

 NOTE: 15 second averaging is recommended for the average setting. All the sensors have settling times of 10 seconds or longer.

Measurements Selectable logged measurements: Level, Lmin, Lmax, Lavg, and STEL.

If the measurement is set to “ On ”, this indicates the instrument will log data at the logged interval (i.e., while in run mode). “ Off ” indicates the measurement will not log when in run mode.

The measurements include the following: Level (instantaneous or averaged measurement), STEL (short term exposure level calculated over last 15 minutes), Lmax (maximum measurement during log interval), Lmin (minimum measurement during log interval), Lavg (average measurement during log interval), and TWA (time weighted average measurement during interval).

Run Time

 NOTE : See “Table 5-3” for more information.

Depending on the logged parameters that are turned “On” for data log and the log interval, the Estimated Run Time screen will display the total remaining run time. For example, if you want to log all parameters the overall run time will decrease significantly. If you would like to extend the run time to a longer duration, logging one or two parameters would be advisable.

Setting up Particulate Settings

There are four parameters in the particulate screen which include:

 Particulate field - enables and disables when measuring particulates. (If disabled, it will not enable the pump during run mode.)

 Profile field – used to select the active particulate profile. The active profile can be edited by pressing the edit quick key.

 Gravimetric Mass and Gravimetric volume fields – displays the accumulated theoretical particulate mass and air volume which has passed through the gravimetric filter (since the last gravimetric reset). These can be reset by pressing the reset quick key.



Setting Profiles (Particulate Correction Factors)

Setting Profiles (Particulate Correction Factors)

The EVM supports eight different particulate matter (PM) profiles with customized name settings and user correction factor settings. When the profile field is selected from the particulate menu, you are able to edit this field by pressing the Edit soft key. Once opened, you can change the profile name and correction factor setting. ( NOTE: Each profile stores up to four calibration verifies.)

1. Profile Name: You can change profile name and assign up to eight characters.

2. Factors: A user will have different correction factors based on the type of dust you are measuring.

How Particulate Factors are Adjusted and Calculated

All particulate profiles are factors are calibrated to Arizona Road Dust (ARD) with its particle size and composition. Other dust compositions can be measured accurately by adjusting a profile’s correction factor.

 NOTE : For best measurement results, it is recommended to enter in the dust correction factor prior to your particulate study. (This may require a gravimetric sampling.)

To calculate a correction factor , follow the guidelines below:

1.

Run the instrument in the applicable environment for a set period of time/volume (i.e., 6–8 hours).

 Accumulators:

 The gravimetric mass accumulator will display the amount of dust accumulated based on the active profile.

 The gravimetric volume accumulator will display the amount of volume passed through the gravimetric filter.

2.

After the run, check the gravimetric mass accumulator, compare to what was actually measured from the lab, and enter in a correction factor.

 For example, before measuring ensure the gravimetric accumulators are reset and the gravimetric filter is replaced. Next, you measure for four hours and the gravimetric accumulator is displayed as 10 mg. Then, you measure the dust in the gravimetric filter (or cassettes) and determine the actual weight. If the actual weight is 20 mg, you would change the correction factor from 1 to 2.

Dust Correction Factors (Profiles)

When setting up the particulate parameters, it is good to keep in mind that the user defined profiles (or correction factors) are a submenu of the particulate menu. Because of this layout, the following section explains how to change the profiles/correction factors and apply a new profile.
