INSTRUCTIONS FOR USE
SAEHAN SPRING HAND DYNAMOMETER
SH5002
GENERAL:
This device is to measure hand grip strength and used to secure an index of general upper
body strength adjust the hand grip size to exert the subject’s maximum grip. Move pointer
lever to zero with your finger allow three trials with each hand alternating. The device
should be checked for correct condition prior to each usage by a person familiar with proper
operation of the balance.
For continuous use for years, take care of it, keep in the protective carrying case to prevent
damage from water and accidental dropping. Wipe off any water or liquid to prevent the
spring from rusting.

SAFETY PRECAUTION :
Carefully read this operation manual before setup, even if you are already familiar with SAEHAN
Spring dynamometer.
Precautions for use
- Do not set the handle grip to a position less than 4 cm as shown by the grip size
scale.
- Do not turn the cap.
- Do not drop the instrument, otherwise, it may be damaged, Handle it carefully.
- Do not use or keep the device in direct sunlight, in area of high temperature,
especially in places near heating equipment, in moist or dusty places, or where it will
be directly exposed to water.
- If the device is dirty, wipe it with a soft, dry cloth, if very dirty, use a cloth wet with a
neutral detergent. Do not use thinner, alcohol, or similar liquids. They will damage
the surface of the device.
- Do not test if you have arm or shoulder pain, or high, uncontrolled blood pressure.
- Use the proper technique as described below for accurate and consistent results. If
needed, ask for a demonstration.
- Adjust the handgrip dynamometer so the second joint of the fingers fit snugly on the
handle when gripping. Hold the dynamometer with arm extended down about thigh
level.
- Make a maximal squeeze. Don’t let the dynamometer touch any part of the body or
any other object. Also avoid sudden thrusts or jars, which can make the reading
inaccurate.
- When squeezing, breathe out or exhale during contraction to prevent high
intrathoracic pressure. Don’t hold your breath and strain.
- Measure both hands. Take three tries per hand. Combine the best score of each
hand to give a total grip strength reading. Record test results in kilograms.
OPERATING INSTRUCTION :
1. Have Subject hold the spring Hand Dynamometer with the scale facing away from his
face. Adjust the grip size until the joints of the Subject’s fingers are approximately on a
plane perpendicular to the scale plate. When the adjustment is optimal, the subject will
sense he can comfortably exert his maximum grip.
2. Move the pointer to zero with your finger.
3. Subject should stand straight with his weight evenly distributed on both feet. With his
arms hanging at his sides, he should squeeze the Spring Hand Dynamometer with as

much force as possible being careful to squeeze only once. Record the resultant scale
reading.
4. Allow three trials with each hand, right and left hand alternating. There should be a brief
pause of about 10 to 15 seconds between each trial to avoid excessive fatigue. Record
the amount registered at each trial, but use only the highest recorded for each hand.
Compare your findings with the averages shown in Table 1 and 2.
Measurement :
1. Holding device in one of your hands, turn the knob to adjust the grip range until the
second joint of your forefinger is bent through 90 degrees.
2. Stand upright and relaxed, extend your arms downward, and grip the device and exert full
force without letting your arms touch your body. During the measurement, do not wave
the device.
3. Read the value displayed on the dial face and record it.
l Turn the pointer to set the pointer zero again.
Methods :
1. Have the subject hold the spring hand dynamometer with scale facing away from his face.
2. Adjust the grip size until the joints of the subject’s finger same approximately on a plane
perpendicular to the scale plate.
3. When the adjustment is optimal, the subject will sense he can comfortably exert his
maximum grip.
4. Move the pointer lever to zero with your finger.
5. Force Range : Measures from zero to 100 kg (220 pound).
6. Resolution and precision
Measurement graduations are every five pounds (within the red inner ring) and every 0.5
kg (whthin the black outer ring).
STRENGTH NORMS :
Grip strength, measured with hand grip dynamometer, correlates with overall upper body strength
and is an easy, safe test to perform, A good grip is linked to higher lean body mass, lower risk
of disability in old age, and increased longevity. Compare your test results with the norms shown
below.
