DHD-1 Digital Hand Dynamometer – Service and Warranty Information

Service Tips

The 

SAEHAN

 DHD-1 Digital Hand Dynamometer is designed to provide 

many years of dependable service with minimal maintenance. To make sure the 

device is reading accurately, we suggest occasionally making the few checks 

listed below. If you detect a problem, return the device for service. Store the 

device in a safe location to prevent inadvertent damage using the case provided 

with the DHD-1.

LCD Display

The DHD-1 features digital load cell technology which eliminates the 

possibility of oil leakage associated with hydraulic hand dynamometers. 

However, if the LCD display does not work properly, the DHD-1 should be 

returned to your supplier or to 

SAEHAN

 for inspection and repair.

Adjustable Handle

Hold the device normally and look carefully at the way the forks of the 

adjustable handle are supported on the posts. Each fork should touch the post 

close to its center. If they do not, return the device to your supplier or 

SAEHAN

 

for inspection and repair.

Annual Calibration and Repair

It is recommended that this device be checked for accurate calibration annually. 

If the device has been dropped or there is reason the suspect that calibration is 

required, the device should be serviced immediately. Contact your supplier or 

call 

SAEHAN

 at 

+82-55-294-0381

, 24-hour phone support at 

+82-10-5282-

0161

, or send email to [email protected]. Additional product and service 

information can be obtained at www.saehanmedical.com.

One-Year Limited Warranty

SAEHAN

 warrants the DHD-1 to be free from defects in workmanship and 

materials for one year from the date of purchase. If this device is found to be 

defective during the one-year warranty period, 

SAEHAN

 at its discretion will 

repair or replace the DHD-1. Thereafter, if the DHD-1 is not working properly, 

there will be a service charge for repair.

This One-Year Limited Warranty does not cover damage due to dropping 
this precision device. Please use the wrist strap to avoid accidental damage.
