13. Maintenance
• Do not use any battery except BP-308. Other battery may lead break
down and fire.
• The date and time setting is reset when battery is disconnected.
14. Warranty
14-1. Product Warranty
We warrant the products to be free from defects in workmanship and material under
normal use and proper maintenance for one year from original purchase.
* Please make sure to read through the included warranty for guarantee conditions.
* We cannot guarantee the products without warranty.
14-2. Pass Certificate for eZT Amplifier
eZT amplifiers are tested based on the company standards and checked under the
environment detailed below.
* Tempe21 to 25 degrees Celsius, Humidity 30~65%RH
We do not issue certificates for passing the checks, although only the products that
have passed those tests are shipped.
13-3. Overall Accuracy of eZT and eZ Connect load cell (eZT only)
Overall accuracy is calculated as below (e.g. eZT and eDPU-50N):
eZT and eZ Connect load cells can be used in various combination, therefore each is
tested individually.
The amplifier and the load cell are not calibrated (actual loading calibration) together.
It is recommended to calibrate by yourself or with our calibration service.
(see page 41 [13-2 Calibration and Repair] for details)
13-2. Calibration and Repair
We offer calibration service with charge. To maintain the best accuracy and reliable
measurement, the periodical calibration is recommended. Please ask your local
distributor about fee and lead time. Please note that the function setting (Program
Menu) and saved data may be erased when repaired. Please make sure to send the
force gauge with the carrying case to protect the gauge.
13-1. Battery Change
The force gauge has rechargeable battery inside. If the
battery is worn out soon after charging or not charged
at all, the battery is dying. Please change the batteries.
(Battery model: BP-308) The direction is as follows.
Turn off the force gauge. Loosen the two screws on the
back of force gauge and remove the battery cover.
Take the battery out and disconnect the connector. (Pull
off the connector with tweezers and needle nose pliers.)
* Please note that the cable may get bad if force to pull the
cable out.
Connect the connector of the new battery. Put the new
battery into the case and fix the battery cover with the
screws. Make sure to store the cable of battery inside.
