Safety Information - Read First

Use the detector only as specified in this manual, otherwise the protection provided by the detector may be impaired.

International symbols used on the detector and in this manual are explained in Table 2.

Read the Warnings and Cautions on the following pages before using the detector.

ec Note

This instrument contains batteries. Do not mix with the solid waste stream. Spent batteries should be disposed of by a qualified recycler or hazardous materials handler.

Page 15

GasAlertMicro

Safety Information - Read First

a Cautions

⇒ Warning: Substitution of components may impair Intrinsic Safety.

⇒ Do not use the detector if it is damaged. Before you use the detector, inspect the case. Look for cracks or missing

parts.

⇒ If the detector is damaged or something is missing, contact BW Technologies immediately. See “Contacting BW

Technologies”.

⇒ Make sure the battery holder is locked in place before you operate the detector.

⇒ Use only a sensor specifically designed for your GasAlertMicro model. (See the section “Replacement Parts and

Accessories.”)

⇒ Calibrate the detector before first-time use and then on a regular schedule, depending on use and sensor

exposure to poisons and contaminants. BW recommends at least once every 180 days (6 months).

⇒ BW recommends to “bump test” the sensors, before each day’s use, to confirm their ability to respond to gas by

exposing the detector to a gas concentration that exceeds the high alarm setpoints. Manually verify that the audible and visual alarms are activated. Calibrate if the readings are not within the specified limits.

⇒ It is recommended that the combustible sensor be checked with a known concentration of calibration gas after

any known exposure to catalyst contaminants/poisons (sulfur compounds, silicon vapors, halogenated compounds, etc.).

Page 16

GasAlertMicro

Users Manual

a Cautions (cont.)

⇒ The combustible sensor is factory calibrated to 50% LEL methane. If monitoring a different combustible gas in the

% LEL range, calibrate the sensor using the appropriate gas. High off-scale % LEL or % v/v methane readings may indicate an explosive concentration.

⇒ Protect the combustible sensor from exposure to lead compounds, silicones and chlorinated hydrocarbons.

Although certain organic vapors (such as leaded gasoline and halogenated hydrocarbons) may temporarily inhibit sensor performance, in most cases, the sensor will recover after calibration.

⇒ Any rapid up-scaling reading followed by a declining or erratic reading may indicate a gas concentration beyond

upper scale limit, which may be hazardous.

⇒ Use only recommended AA alkaline or NiMH batteries properly charged, and installed in the detector case. (See

the section “Replacement Parts and Accessories.”)

⇒ Charge NiMH batteries using recommended charger only. Do not use any other charger. Failure to observe this

precaution could lead to fire or explosion.

⇒ Do not change or charge batteries in a hazardous location. Doing so will impair the Intrinsic Safety of the unit and

may lead to fire or explosion.

⇒ Read and observe all instructions and precautions in the literature provided with the charger. Failure to do so may

result in fire, electric shock or other forms of personal injury or property damage.

Page 17

GasAlertMicro

Safety Information - Read First

a Cautions (cont.)

⇒ Extended exposure of the GasAlertMicro to certain concentrations of combustible gases and air may stress a

detector element, which can seriously affect its performance. If an alarm occurs due to high concentration of combustible gases, recalibration should be performed, or if needed, the sensor replaced.

⇒ Do not test the combustible sensor’s response with a butane cigarette lighter; doing so will damage the sensor.

⇒ Do not expose the detector to electrical shock and/or severe continuous mechanical shock.

⇒ Do not attempt to disassemble, adjust or service the detector unless instructions for that procedure are contained

in the manual and/or that part is listed as a replacement part. Use only BW Technologies replacement parts.

⇒ Do not immerse the detector in liquids.

⇒ The detector Warranty will be voided if customer, personnel or third parties damage the detector during repair

attempts. Non-BW Technologies repair/service attempts void this Warranty.

are available from BW Technologies. See the section “Replacement Parts and Accessories

• Calibration accuracy is never better than the calibration

gas accuracy. BW Technologies recommends a premium-grade calibration gas. Gases with NIST (National Institute of Standards and Technology) traceable accuracy will improve the validity of the calibration. Do not use a gas cylinder beyond its expiration date.

• Calibrate a new sensor before use. Install the sensor,

activate the detector, and allow the sensor to stabilize

.”

before starting calibration (used: 60 seconds; new: 5 minutes).

• Calibrate the detector on a regular basis, depending on

use and sensor exposure to poisons and contaminants. BW recommends at least once every 180 days.

• Calibrate the detector if the ambient gas display varies at

startup.

• It is best to calibrate the sensor before changing alarm

setpoints.

• Calibrate only in a clean atmosphere that is free of

background gas.

• To disable an alarm, set its alarm setpoint to 0.

• The combustible sensor is factory calibrated to 0 to 100%

LEL using methane. If monitoring a different combustible gas in the 0-100% LEL range, calibrate the sensor using the appropriate gas.

• The Oxygen sensor can be automatically calibrated each

time on activation, if this feature is enabled. Activate the detector in a normal (20.9% Oxygen) atmosphere.

• If you require a certified calibration, contact

BW Technologies. See “P.2

”

Page 40

Users Manual

• The detector should be allowed to stabilize for 1 minute,

after activation, prior to calibration or a bump test.

Diagnostics Protection

The detector tests the ambient air (Auto Zero) and the test gas applied (Auto Span) to ensure it meets expected values.

In Auto Zero, if any background target gas is present, the sensor(s) affected will read function, retaining the previous set value(s).

In Auto Span, if any target gas is not present or does not meet expected values, the display will advise you and exit calibration mode, retaining the previous set value(s).

Err and exit the Auto Zero

Applying Gas to the Sensors

The calibration hose, which is shipped with the detector, simplifies sensor testing and calibration. Table 10 and Figure 3 show how to use it when applying gas to the sensors.

Calibration Procedure

To calibrate the detector and set its alarm setpoints, perform the following:

Start Calibration

Note: To quit at any point after auto zero, press A. The detector retains any saved values, and the audible alarm beeps 4 times before the detector returns to normal operation.

Note: At any point after auto zero but before calibration gas is detected, press alarm setpoints.

Note: Verify that the calibration gas you are using matches the span concentration value(s) in the detector. See the

section “Set Span Concentration Values

1. In a clean atmosphere, press C and H simultaneously

and hold for 5 seconds. The detector beeps 4 times and the display shows:

The audible alarm then beeps once signifying that calibration has begun.

Auto Zero and Oxygen Sensor Calibration

The display flashes N while the detector automatically zeroes the toxic sensors and calibrates the Oxygen sensor.

Auto Zero Sensor Fail

The audible alarm then beeps twice.

Note: Do not apply the calibration gas until the display shows K; otherwise, the auto zero step will fail.

Users Manual

Pass Code Protect: If the detector is pass code protected, after a successful Auto Zero, the detector will prompt for the pass code before proceeding to Auto Span and Alarm Setpoints. See the section “Pass Code Protection

”.

Auto Span

Calibrate one, two, three or four sensors as desired.

The display shows gas to the sensor or skip the span (sensitivity adjustment):

2. Install the calibration cap and apply gas to the sensor at

a flow rate of 250 to 500 ml/min. Or, press C now to skip the span.

When the detector senses approximately one-half of the expected gas concentration (30 seconds), the audible alarm beeps once. The detector then begins spanning the sensor(s) (2 minutes).

The audible alarm beeps 3 times at the end of the span. Remove the calibration gas.

K, prompting you to apply a calibration

Auto Span Sensor Fail

If a sensor fails, the display advises Err and skips the span for the failed sensor(s). Other sensors span normally. Press A to exit, and then restart calibration in an atmosphere that is clear of the targeted gases. If the auto zero fails a second time, restart the detector to test the sensors.

Note: The detector will not span a sensor if:

• You do not apply gas to the sensor.

• The sensor fails to detect at least one-half of the

expected gas concentration in the first 30 seconds.

• The gas concentration drops below one-half of the

expected gas level during the 2 minute span.

If you apply gas to a sensor and the detector fails to span the sensor, repeat the calibration process using a new gas cylinder. If the sensor fails the span a second time, replace

the sensor. See the section “Replacing a Sensor or Sensor

Filter”.

If the span adjustment is an unusually large (more than 20 %), the detector will advise:

note: Span adjust unusually large - check that the cal gas is correct.

Confirm that the calibration gas bottle you are using is correct and that the span concentration value(s) in the detector match the value of the calibration gas bottle. See

the section Set Span Concentration Values

If the calibration adjustment is expected accept the calibration.

Span Adjustment Accept/Reject

If a span is rejected, the display advises: Note: Span

Users Manual

E.D.M. Workbook Features and Functions

The customized Excel workbook created by the E.D.M. wizard provides the datalogger data in a preformatted layout. Several automatic features and functions are available to simplify the data management process, such as color-coding, data filtering and automatic charting.

Data workbook format

Titles and worksheets

The workbook is titled according to the instrument type used to collect the data. The title is shown at the top of the data file, i.e. “GasAlertMicro data file”.

Each workbook will contain as many sheets as is necessary to hold all of the imported data. Excel has a built-in limit of 65,535 lines per worksheet. Since datalogger files may include up to 2,100,000 lines of information, the information is split across several worksheets in the same workbook when required.

Sheets are named according to the serial number of the instrument used to record the data. If there is more than one sheet for a given instrument, the sheet names will be appended with –1, -2, and so on, as in ‘123456-1’, ‘1234562’ etc.

Type and order of displayed data

Data is presented in chronological order by date. The day of the week and the instrument serial number is also presented, followed by the instantaneous gas readings and time weighted-average (TWA) readings as calculated by the instrument.

Status messages for each sensor are also shown. These messages indicate if the sensor is operating normally, or has some type of alarm, failure or condition that is different from normal operation. Possible conditions include low alarm, high alarm, TWA alarm, calibration, last calibration, alarm setpoints and sensor self-test failure. Status codes for the sampling pump (if present), data logger, instrument battery and instrument alarms are also shown.

Sensor readings that exceed the alarm points are highlighted in color. Yellow shading indicates low alarm conditions. Red shading indicates high or TWA alarm conditions.

Overlapping or older data

Because the data is sorted by date & time, the data file will not contain overlapping data unless the internal clock settings of the datalogger instrument have been changed.

In most cases, data files will contain data that has been previously downloaded from the card. This is a consequence of the large data storage capacity of the MultiMediaCard

Page 65

GasAlertMicro

E.D.M. Workbook Features and Functions

flash memory, and of the nature of the datalogger operation. The card will generally contain data from the previous 300 hours of operation.

In some cases, depending on use, the data file may contain fragments of data that are older than the last 300 hours of use. This is a normal consequence of the datalogger operation and is not a sign of malfunction. The data is not automatically deleted because the software cannot determine if the data is important or not. If desired, the older data may be easily deleted or filtered out using the built-in features of the spreadsheet

Working with the data

Data in the Excel workbook can be manipulated using Excel’s built-in functions. Excel supports search, search and replace, sorting and many other data handling functions.

There are also several built-in features that will help automate and simplify routine data management tasks.

Entering user data or comments

There is a general comment field at the top of each worksheet that may be used to enter user information about the logger data. This general comment field is automatically mirrored to the other associated worksheets in the workbook, so the comments need only be entered once.

Changing or removing the preformatted cell colorcoding

Gas readings are color-coded according to alarm conditions. If you wish to remove change or the color coding, select the ‘Conditional formatting’ option under the ‘Format’ menu.

To change the color-coding to a new system, enter new rules in the ‘Condition’ boxes. You may also change the format of the cells that match the rules by pressing the ‘Format’ buttons. Refer to Excel help for more information on creating and using conditional formatting.

To delete the color-coding, press ‘Delete’, check all of the checkboxes, and press OK. This will remove the rules that Excel is using to determine if the cell should be shaded or not.

Sorting: Reorganizing the data

The worksheet data is normally shown in chronological order. To re-sort the data, select the appropriate rows and select ‘Sort’ from the ‘Data’ menu.

When sorting data, ensure that you select complete rows. If you do not, the sensor readings may no longer correspond to the correct time & date.

Users Manual

Filtering: Restricting the viewed data by date, gas reading or status code

Data managers often wish to view only events that occur within a specific time frame, exceed a certain gas or accumulated TWA level, or some other particular set of conditions. The EDM workbook provides automatic filters that automate this task.

To filter the displayed data on any column, click on the down arrow icon present in the column header. A list of filtering choices is then presented. Either select once of the displayed choices, or ‘Custom’ to define new filtering criteria.

Filters may be applied to several columns at once to further narrow down the viewed data. Filters may also be applied to status fields, so that events such as pump failures, instrument calibrations and low-battery warnings can be easily pinpointed.

Data is not lost or removed from the worksheet when filters are used. To view all of the available data, re-select the filtered columns and click ‘All’. You may have to do this for several columns before all of the data appears if several filters are in use at the same time.

Examples:

• To restrict by date: Choose ‘Custom’ from the date & time header. In the dialog box that appears, click on the down arrow icon for the top left-hand box, and select ‘is greater than or equal to’. Click on the down arrow for the top right-hand box, and select the start date. Repeat this process for the other boxes, selecting ‘is less than or equal to’ and the end date.

Note: dates that do not appear in the current worksheet will not be displayed.

• To restrict by gas level: Choose ‘Custom’ from the relevant gas. In the dialog box that appears, select the ranges you wish to view for that gas. Note: gas levels that do not appear in the current worksheet will not be displayed, but may be typed in manually. You may repeat this for other gases to further restrict the viewed data.

Note: The filtering process may take some time to complete on slower machines, or on larger data files.

Charting: Automatically charting the data

Data for the active worksheet may be charted by pressing the ‘Chart Data’ button at the top of the worksheet. Data for the current sheet will be graphed and displayed as a new chart sheet. The chart sheet is automatically named according to the worksheet that was charted.

Page 67

GasAlertMicro

E.D.M. Workbook Features and Functions

To chart a section of data, use the data filters (described above) to restrict the data display to the section or type of data you are interested in. Pressing the ‘Chart Data’ on filtered data will chart only the data being displayed at that time. This allows automatic charting of any data subset required.

Charting: Manually charting the data

Data that is split between worksheets cannot be charted automatically. To chart data that is split between two worksheets, copy the data in question from the two sheets to a new worksheet. Note that Excel has a built-in limit of 65,535 lines per worksheet.

To successfully chart the data, it is necessary to split the ‘Date & Time’ column into two columns. This is necessary because Excel does not correctly interpret the combined date and time.

The simplest method to do this is to make two copies of the date & time column beside each other. Reformat column 1 to ‘Date’ using the ‘Format cells’ command, and reformat column 2 to ‘Time’. You then may select the data you wish to graph and use the Excel Chart Wizard to create the graph of your choice. For more information on the Chart Wizard, refer to Excel help.

Examples

• To chart data over a date range: use the filter on the date & time column to restrict the viewed data to the appropriate range. Pressing ‘Chart Data’ will then automatically chart the displayed data.

• To chart data over two worksheets: Copy the required data to a new worksheet. Copy the ‘Date & Time’ column into two columns. Reformat column 1 as date, and column 2 as time. Select the data to graph and press the ‘Chart Wizard’ button to graph the data.

Note: The charting process is complex and may require some time to complete on slower machines, or if large amounts of data is being charted. Also, Excel has a built-in charting limit of 32,000 data points. To obtain larger graphs, a database system such as Microsoft Access is required.

Printing: Printing the data

The workbook settings are pre-formatted to allow for easy printing. Column headings and comments appear on each printed sheet.

Users may, of course, customize the printout to their individual requirements by using Excel’s built-in printing features. Refer to the Excel help files for more information.

Page 68

GasAlertMicro

Users Manual

Security: Locking or protecting the data

Excel incorporates security features that allow spreadsheet data to be locked against accidental or deliberate alteration, from entire worksheets to individual cells. For more details, refer to the Excel help files.

Customization: Calculating long-term average exposures

Because of the large variety of different long-term calculations used in the safety workplace, the EDM workbook does not support automatic long-term calculations.

However, long-term average exposures of any type may be calculated using Excel’s built-in mathematical functions. Refer to the Excel help file or user’s manuals for more information on how to construct the desired formulae.

Direct Import to Compatible Programs

Information from this point on applies only to users who are not using the E.D.M. plug-in. The following information applies to direct data import into Excel and other compatible programs. To use the datalogger data, insert the data card into a computer adapter and open the data file LOGFILE0.CSV using spreadsheet or database software. Word processors and text editors may also be used, but performance may be poor, since the datalogger file is at least 16 megabytes in size.

Data for user-accessible models is comma-separatedvalues (CSV) format. The data order is:

• Date, day, time

• H

S, CO, Combustibles, O2

S TWA, CO TWA

• H

• Status codes, serial number Recorded data includes eight single-character unit status codes. The eight characters represent codes for the H CO, combustibles, and O status, and unit alarm status. A summary of most of the available codes can be seen in table A.

sensors, datalogger, unit battery

Importing the Data File Into Compatible Desktop Applications

MultiMediaCard Compatibility

A standard 32MB MMC Flash Memory card is supplied with the detector. When purchasing additional MultiMediaCards, BW Technologies recommends MMC Flash Memory cards that contain between 32 MB and 128 MB storage capacity.

MultiMediaCard(s) compatible with the “MMC“ specification will always have the exact word “MultiMediaCard“ or “MMC“ written on the disk or package. Cards that do not contain these exact words are not a MultiMediaCard.

The “MMC“ is not the same as the following:

• MultiMedia card;

• Multi media card;

• SmartMedia

• CompactFlash

• Memory Stick

MMC cards are available through retailers throughout the world. They are also available through mail order and Internet vendors.
