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.

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
15
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

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
16
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
17
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
18
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.
