G Lab Meters

The G-LAB line of personal wearable G-Force Meters gives active humans the ability to accurately measure the maximum sustained G-Force and the Air Time they experienced during an activity. Small, lightweight, and inexpensive, the G-LAB Meters are worn around the waist using the included belt. The large display and single large tactile button makes control of the G-LAB meters easy even in extreme environments and while wearing gloves.

The G-LAB 100 is similar to a digital thermometer in operation. One press of the button turns the display on and starts G-Force monitoring. Impacts and shocks are filtered out so that the maximum recorded short and long duration G-Force is a true sustained G-Force level. The kind of G-Force you feel in your gut. The G-LAB 100 also calculates the amount of time the user is near 0 G, what we call “Air Time”. The display continuously alternates between the maximum short and long duration G-Level and the accumulated air time. At the end of a run, press and hold the button to clear the data and put the meter in sleep mode.

The G-LAB 100 continuously calculates the G-Force independent of orientation. It doesn’t matter if the meter is upside down, sideways, or any other way. It will always read the maximum sustained G-Force and Air Time regardless of direction or orientation.

With cases made from aluminum and polycarbonate, the G-LAB meters are built to take a beating. Simple automatic re-calibration and extreme shock tolerance means high accuracy each time the meter is used. The G-LAB 100 runs more than 200 hours on a single low cost coin cell.

The G-LAB 100 displays 3 values:

Short Duration Sustained G-Force, 7.00 G maximum
Long Duration Sustained G-Force, 7.00 G maximum
Air Time (0 G’s) in seconds, 59.9 seconds maximum

Operation

The G-Lab 100 calculates the maximum vector G-Force independent of the meter’s orientation to the Earth or the direction of the motion generated acceleration, while filtering out short duration shocks. The Air Time reading shows the number of seconds the meter detected free-fall. The G-LAB should be worn snugly around the waist, making it close to your center of mass, using the supplied belt. The G-LAB displays G-Forces created by motion. When the meter reads 1.00 for G-Force for example, you experienced a motion generated force in addition to, and equal to, the force of Earth’s gravity.
The meter comes with a battery installed. To replace the battery, remove the 4 screws in the cover. After removing the cover, the battery slides into the battery holder from the side. THE BATTERY MUST BE INSTALLED WITH THE POSITIVE TERMINAL FACING UPWARDS. When the battery is installed, the display will show the software version, and then “CAL”. Replace the cover (make sure the gasket around the switch remains in place) and tighten the 4 screws. Then proceed to Calibration.

Calibration

The G-LAB 100 contains a precision 3 axis accelerometer. To properly compensate for your location on the Earth (elevation, latitude and extreme temperatures) the meter needs to be calibrated. Calibration is started automatically when a battery is installed, or by holding the button down when turning the meter on. When the display shows “CAL”, place the meter with the display facing up on a stable level surface. Press the button once. The display will flash “CAL” during the calibration process. The meter must not be moved during calibration. When complete, the meter will enter the normal on state. If the display shows “Err” (Error), press the button again to retry calibration. If the display still shows “Err”, remove the battery for 30 seconds, and repeat the calibration process making sure the meter is motionless and level.

Battery

The meter has two states, on and off. While on, the meter is continuously calculating the G-Forces and displaying the short and long duration maximums and air time. To turn the meter on, press the button. While on, the display will alternate between the 3 values. When the decimal point is over the “G”, the short or long duration G-Force reading is being displayed. When the decimal is over the “A”, air time is being displayed. The short duration reading is shown 1st and will always be greater than (or equal to) the long duration reading. To turn the meter off and clear the data, press and hold the button until the display goes blank. Always turn off when not in use to extend battery life. The display will flash when the battery is getting weak.

Warranty

The G-LAB 100 is guaranteed to be free from defects for 1 year from date of purchase. Abuse is not covered. The product will be repaired or replaced at no cost. Return the product, with proof of date of purchase, postage paid to G-LAB with a description of the problem, return address and contact information.
