Parts of a Dynamometer

• After removing the Dynamometer, check that the
  black Gauge Needle is above the 0.

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

Preparation for the Test

• Rotate the red Peak-Hold Needle counter-clockwise
  to zero

• Have the patient grip and place the strap on the
  wrist of their dominant hand

• Pass the Dynamometer to the patient
• Do not hold Dynamometer from the gauge (top)

Adjusting the Handle

• If the handle feels too large or small for the
  patient to grip comfortably, remove Dynamometer
  from the patient and adjust accordingly as shown

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.
