Common Asked Questions
How do I adjust the needle on my hand dynamometer or pinch gauge to zero?
The gauge needle may be above or below the zero reading upon receipt of the instrument. The gauge on this instrument is sensitive to pressure changes due to changes in altitude and will most likely require an adjustment to re-zero the instrument.
Follow these steps to return the gauge needle to zero
- Unscrew (counterclockwise) and remove the lens from the gauge (the red peak-hold needle is attached to the lens)
- Remove the handle (to prevent applying pressure during this process)
- Place the instrument on a sturdy surface
- Using a small, slotted screwdriver, rotate the slotted screw counterclockwise in the gauge dial face until the needle is below zero (if it is already zero, turn the cam until it is slightly farther below zero)
- Turn the screw in the reverse direction until the gauge needle is almost touching the zero line
- Reattach the gauge lens and the handle
- Pick up and squeeze to apply pressure to the instrument a few times
- Place the instrument back on a sturdy surface and return the red peak-hold needle to zero by turning the center knob
- Check to see that the red peak-hold needle is at zero
- If the red peak-hold needle is not on zero, repeat steps 1-10 until the red peak-hold needle is at zero
How do I clean/disinfect my hand or pinch dynamometer?
Cleaning with mild antibacterial soap and water is recommended. Do not soak or saturate the device with water. The handle and posts can also be cleaned with an isopropyl alcohol wipe. Do not use alcohol on the plastic gauge faceplate or cover.
