The Department of Transportation has cited the following notice for consideration when using an alternative power source for the unit.

DEPARTMENT OF TRANSPORTATION Research and Special Programs Administration [Docket No. RSPA-99-5143; Notice No. 99-8] Advisory Guidance; Transportation of Batteries and Devices That Contain Batteries AGENCY: Research and Special Programs Administration (RSPA), DOT. ACTION: Advisory guidance.

2 GP1 PROGRAMMABLE ACCELEROMETER

2.1 General

The GP1 Programmable Accelerometer is a 3-axis motion recording instrument that allows the user to monitor, record and evaluate: motions, impacts, shocks, drops, orientation and temperature.

2.2 Specications

Size: 3.935” x 2.560” x 1.140” Weight With Batteries: 8.25 oz Housing Material: 6061 - T6 Aluminum Power: 2 x AA Alkaline Batteries Battery Life: More than 40 Days Connectivity: USB Accelerometer Type: Programmable 3 Axis MEMS Accelerometer Range: User programmable ±2.5g, ±3.3g, ±6.7g, ±10g Frequency Response: DC - 45Hz Sampling Rate: 100Hz per axis Memory Type: Non-Volatile EEPROM Memory Size: 1 Megabyte Device Temperature Range: -20°C to +80°C

2.3 Acceleration Ranges

The GP1 incorporates a programmable 3-axis MEMS accelerometer. The user can select which range is appropriate for their application. The four acceleration ranges are: ± 2.5g, ± 3.3g, ±6.7g and ± 10g. It is recommended that the user select the lowest range reasonable for their application as this will optimize data. Choosing an acceleration range does not limit the survivability of the accelerometer; the accelerometer is shock rated for more than 1000gs.

GP1 USER GUIDE

2.4 Data Recorder Mode

When the GP1 collects data in the Data Recorder Mode it organizes sampled data into user-specied reporting intervals. A reporting interval is dened by a time segment the user denes; a time segment can be between 1 second and 120 seconds. The reporting interval does not inuence the way the GP1 collects data, it only species the time resolution for reporting the data. For example, if the GP1 is set to report X+ axis max values with the specication of a 1 second reporting interval, the unit will sample at 100 samples per second and report the single highest sample within a given 1 second period. If the device’s reporting interval were reset to 60 seconds the GP1 would still sample at 100 samples per second but report the highest sample that occurred within the 60 second period. Choosing a shorter reporting interval will result in more data records for a given monitoring period. Selecting an appropriate reporting interval is a balance between data resolution, record length and storage capacity. Once a reporting interval is specied the software will display the number of days and hours the unit will store data. In general 60 second epochs is a good reporting interval for most applications—it facilitates reasonable data resolution and an extended monitoring period.

Note: The GP1 reports all records in UTC time.

2.5 Event Recorder Mode

The GP1 can also be programmed to collect data in the Event Recorder Mode. This mode records each sample (3 axis—100 samples per second) into sequenced data records. Once the Event Recorder Mode is enabled the user can specify when the mode triggers and how long the mode records data. This mode can be used in conjunction with Data Recorder Mode.

2.6 Real-Time Data Capture Mode

The GP1 can be congured to be a real-time data capture device—this mode lets the user see the real-time acceleration inuences as they are occurring. For this function the unit needs to be connected to the user’s PC via the USB cable. No other modes can be used while Real-Time mode is enabled. Once enabled, the user can control when the system records/displays data. Recording control can be done on the PC or at the instrument. USB extenders can be used with this mode to increase the cable length if required.

GP1 USER GUIDE

2.7 LED Status Indicator

The GP1 has an LED indicator that can be used to quickly determine the status of the unit. Depending upon the unit’s status, the LED will ash green, yellow or red. Each ash color and ash frequency has a specic meaning depending upon which mode is enabled:

Data Recording Mode Single green ash every 2 seconds Recording normally with no alerts ½ Second green illumination Button press input has been stored Yellow triple-ash every 2 seconds GP1 is armed and awaiting a trigger to start recording Yellow single-ash every 2 seconds Recording data; low battery Red single-ash every 2 seconds Recording with an alert condition detected Red triple-ash Not recording with alerts

Event Recorder Mode Rapid yellow Not recording data Rapid green Recording data

Stream Mode Solid red Not Sampling Data Solid green Sampling Data

2.8 Start Button

The GP1 features a top mounted “Start” button. This button is used to control data recording as well as inserting notice inputs into the data record.

3 DATA RECORDER MEASUREMENTS AND FEATURES

3.1 Maximum Axis Acceleration

The GP1 monitors each axis at the xed rate of 100 samples per second. Peak accelerations are reported for each user specied reporting interval. A peak acceleration value is the highest single sample. Acceleration inputs are ltered through an analog 2 pole Butterworth low pass lter that has a cut-o frequency of 45Hz.

3.2 Minimum Axis Acceleration

Minimum axis acceleration values are the lowest acceleration values sampled. If no negative acceleration values were sampled then the minimum value will be greater than or equal to zero. If a negative axis acceleration input was sampled then the value would be the greatest negative acceleration value sampled.

3.3 Average Axis Acceleration

The average axis acceleration is the sum of the inputs (100 samples per second) divided by the user-specied reporting interval. The GP1 can be congured to absolute value the inputs before reporting the average.

GP1 USER GUIDE

3.4 Axis Threshold Counter

The axis threshold counter counts the number of times the acceleration value for the axis exceeds a user-specied threshold.

3.5 Vector Magnitude (VM) Max

Vector magnitude is a single acceleration value that quanties 3-axis acceleration. The equation for vector magnitude is:

Vector magnitude max is calculated each sample period (100 samples per second) and is the single highest combined axis instance per reporting interval.

3.6 Vector Magnitude (VM) Average

Vector magnitude average is the sum of the VM calculations for the reporting interval divided by the number of samples taken during the reporting interval.

3.7 Vector Magnitude Threshold Counter

The VM threshold counter counts the number of times the vector magnitude exceeds the user-specied threshold.

3.8 Orientation

Orientation is dened as which face is up—the accelerometer is looking for gravity and the largest continuous gravity component to determine which face is up. The GP1 records a complete orientation record citing the time, orientation(s) and duration.

3.9 Near Zero G

Near zero g is a denable threshold that is used to indicate a freefall condition. A freefall condition is achieved when the unit is not being supported and is under the inuence of gravity. Examples of freefall conditions include tosses, drops and throws. The GP1 monitors how many times it senses a freefall condition as well as the duration of the event.

3.10 Peak Duration

Peak duration is a measurement that captures additional details about an acceleration input. Peak duration monitors VM inputs and reports:

a) Peak VM Acceleration b) Duration of the acceleration event that was over a specied threshold c) Velocity change associated with the event

GP1 USER GUIDE

3.11 Temperature

The unit has an internal temperature sensor that is used for accelerometer temperature compensation. The sensor is placed adjacent to the accelerometer and measures the internal temperature of the GP1. The temperature sensor is factory calibrated to be within ±1.5 ° C. Since the GP1 is an extremely low-power device and does not generate any appreciable heat, it does not aect the reported temperature. The GP1 samples temperature every 10 seconds.

The GP1’s temperature response rating is:

Moving Air Still Air

• Time to reach 50% of temperature dierence • Time to reach 50% of temperature dierence 5 minutes 10 seconds 11 minutes 15 seconds

• Time to reach 90% of temperature dierence • Time to reach 90% of temperature dierence 19 minutes 1 hour 8 minutes

3.12 Button Press

The GP1 records when the start button is pressed and held for ½ second. The event is recorded in the data record and can be used to indicate signicant events or timeframes.

3.13 Alerts

Alerts are individual alarm conditions that the user species. Once an alert value is registered the GP1 will indicate that an alert has been stored by triggering the GP1’s LED to begin ashing red. Alerts are indicated and reported in the data record and the summary reports.

Alerts can be specied for the following parameters:

Axis Maximum Alert will be triggered when a single sampled acceleration value achieves or exceeds the specied value.

Axis Minimum Alert will be triggered when a single sampled acceleration value achieves or exceeds the specied values. Axis minimum alerts can be used for negative axis acceleration alerts.

Axis Average Alert will be triggered when the average acceleration value for the reporting interval achieves or exceeds the specied value.

Axis Threshold Count Alert will be triggered when the number of threshold counts for the reporting interval achieves or exceeds the user-specied value.

VM Max Alert will be triggered when a single sampled acceleration value achieves or exceeds the specied value.

VM Average Alert will be triggered when the average acceleration value for the reporting interval achieves or exceeds the specied value.

VM Threshold Count Alert will be triggered when the number of threshold counts for the reporting interval achieves or exceeds the user-specied value.

GP1 USER GUIDE

Orientation Orientation alerts require that the user specify a preferred orientation.

The preferred orientation will indicate how the user will mount the GP1 to the object of interest. Once this orientation is specied the unit will trigger an alert whenever the attitude changes.

Peak Duration Peak Duration alerts can be set up to trigger on any one or all of the settable parameters: peak acceleration input, input duration and velocity change.

Temperature High Alert will trigger when the unit records a temperature equal to or higher than the specied temperature.

Temperature Low Alert will trigger when the unit records a temperature equal to or lower than the specied temperature.

Button Press Once the GP1 has been initialized the user can embed a special time-stamp entry into the data record by pressing and holding the “Start” button for ½ second. The unit’s status LED will ash green when an entry has been stored.

4 EVENT RECORDER MEASUREMENTS

4.1 Axis Acceleration

Event Recorder Mode records each of the individual axis samples (100 samples / second) for display and analysis. The user can congure when the instrument records data by specifying a trigger condition. Acceleration inputs are ltered through an analog 2 pole Butterworth low pass lter that has a cut-o frequency of 45Hz.

4.2 Temperature

Event Recorder Mode samples and reports the instrument temperature; see section 3.9 for system characteristics.
