2. Push the attachment teeth down into the gaps.
3. Twist the attachment clockwise (toward the locked symbol) a full quarter turn.
4. When locked, the attachment will remain in place.
Proper Usage of the ActivForce 2 Device
Measuring Force
The ActivForce 2 device measures accurately when force is applied in a perpendicular direction to the large surface areas of the device or an attached pad. Application of the force should be in the center of the surface as much as possible. Direct all force into the device directly perpendicular through the device's center point.
Do not apply force in a non-perpendicular direction to the device.
Do not apply force at an angle or in a direction going across (parallel to) the device.
Do not apply force on or near to the blue band of the device.
Do not apply a force during the three-second calibration period before the application starts the force measurement.
Do not move or shake the device during the force measurement.
Measuring Range of Motion
The ActivForce 2 device can also measure angular displacement for range of motion testing. While the device is calibrating, make sure that the device is being held still in the starting position.
Do not rotate the ActivForce 2 device in multiple axes during a measurement.
Do not move the ActivForce 2 device in multiple planes of motion during a measurement.
Do not rotate the device during the brief calibration period before the application starts the range of motion measurement.
Place the device and/or subject into the starting position for test measurement and press the “Start Test” button.
After calibration, move the device from the starting position (Position 1) to the ending position (Position 2) through ONE plane of movement only (frontal, horizontal, or sagittal).
Do NOT move the arm back to the starting position while the app is still measuring range of motion. Returning to the starting position before pressing “End Test” will result in an inaccurate reading.

The Hand & Leg Straps
The Hand Strap
When using the Hand Strap attachment, ensure the strap is securely fixed in position. The Hand Strap may be used to secure the device to the user for strength and range of motion tests.
The Leg Strap
When using the Leg Strap attachment, ensure the strap is securely fixed in position. Use the Leg Strap to attach the device to the subject's larger body parts for range of motion tests.
Threading the Hand and Leg Strap
Thread the strap through both loops with the logo face up and the plate face down. Place the device so that the locking mechanism fits into the hole in the plate. Slide your hand between the device and the strap. Pull the non-logo side across your hand. Pull the logo side over and secure the velcro. Use with desired attachment.
The Different Pads
Using the Arched Pad
When using the Arched Pad attachment, ensure the attachment is securely attached in the locking mechanism. Use on hard or bony body parts for strength tests. The curve of the Arched Pad surface can be used to place the device against curved body parts.
The Rounded Pad
When using the Rounded Pad attachment, ensure it is securely attached in the locking mechanism. Use this pad for all grip strength measurements and when bracing a test position against an immovable object.
The Foam Insert and Silicone Cover with the Arched Pad
Use of the Foam Insert and Silicone Cover is optional. For additional subject comfort, the Foam Insert can be attached to the Arched Pad by removing the adhesive backing and adhering it to the surface of the Arched Pad. The Silicone Cover can be secured in place using the grooves in the silicone to fit around the Arched Pad, providing a non-porous surface which can be easily cleaned and disinfected between uses.To ensure accurate measurement and prevent the slippage of the device or Silicon Cover during measurement, force should ONLY be applied in a direction perpendicular to the Pad surface.

The Belt Loop
When using the Belt Loop Plate attachment, keep the belt positioned perpendicular through the loops to reduce strain on the belt loops.The plate is designed to hold the belt in position during a test and it is not designed to withstand force from a test. No force should be applied on the loops for a more accurate measurement. Keep the straps parallel to the direction of applied force so the force is transmitted to the device. Ensure the belt is wrapped over the smooth side of the device and not over the attachment side of the device.
The Round Pad with the Belt Loop Plate is recommended when the device is being pressed into the inanimate object.
The Belt Loop Plate may be used to guide the belt when the device is strapped to a fixed or immobile object.
Cleaning and Disinfecting the Device
To prevent the spread of infection and diseases, the ActivForce 2 device and pad should be disinfected between each use. The ActivForce 2 device's external surfaces, including the rounded pad and the soft, arched pad silicon sleeve, can be hand wiped at room temperature with a soft cloth and a cleaning solution consisting of 70% isopropyl alcohol and water. After application, the cleaning solution should be allowed to evaporate completely.
Alternatively, a cleaning solution of 1% hypochlorite and water (10,000 ppm) can also be used to wipe the device, pads and silicon sleeves. Antibacterial hand sanitizing agents such as non-alcohol wipes or alcohol-based hand gels may also be used. Any residue from these agents should be wiped away using a soft, dry clean tissue or towel.
Replacing the Battery
The ActivForce 2 device comes with a standard AAA battery, which lasts between six to twelve months, depending on usage and environmental conditions. To replace the battery, follow these steps:
Obtain a new AAA battery and a medium size flat-head screwdriver.
Hold ActivForce 2 device and the screwdriver with the pad attachment mechanism facing upwards. The Activforce logo should NOT be visible.
Insert the tip of the screwdriver in the small opening near the power button and gently turn the screwdriver until a CLICK sound is heard and the bottom shell lid pops slightly open. This opens the first of five latches on the bottom lid.
Gently slide the screwdriver clockwise along the edge of the ActivForce 2 device, keeping the tip inside the gap between the lid and the device until it is about an inch and a half away from the original opening near the power button.
Stop sliding and gently turn the screwdriver until a CLICK sound is heard. Continue sliding the screwdriver around the edge with the tip inside the crevice, stopping every inch and a half to turn the screwdriver to pop open the latches of the bottom lid. The bottom lid can be removed when four to five of the latches are opened.
