1 x Jamar Hydraulic Hand Dynamometer Instruction Manual
1 x Jamar Certificate of Calibration

3. Parts of a Dynamometer
After removing the Dynamometer, check that the black Gauge Needle is above the “0”.

4. Resetting the Gauge Needle
If the gauge needle is not above the zero, remove the crystal and using a flathead screw driver move the needle until it is set above the “0” mark

7. Conducting the Test
Have the patient sit upright in a chair with an arm rest. The patients elbow should be at a 90˚ angle
Have the patient squeeze with their maximum strength. Sustain for 5 seconds. The peak-hold needle will automatically record the highest force exerted

8. Conducting the Test
Record the peak value in pounds (inside dial) as shown by the red Peak-Hold Needle
Repeat test 2 more times
Sterilize Dynamometer with an alcohol wipe between patients
This would be a reading of 120 pounds.
