Start-up
Please note that the Centor First II measures very small changes in force and may not read exactly zero
if it is moved during its self-test procedure. When properly mounted and zeroed, the reading remains
stable.
To switch on, press the key , a short self-test procedure displays the following screen
After the self-test, if the device is functional, the force gauge displays the measurement screen. It then
displays 0 N. A tare is performed when the device is started.
If the applied force is greater than 20% of the maximum capacity, the force gauge displays a
maintenance screen. At the bottom of this screen, the force applied in % is indicated. The unit is not
usable if the force at startup is greater than 20%. It is then necessary to turn off the force gauge and
remove the preload before turning it on again.
For example, for a force gauge with a capacity of 500N, the force applied to the sensor must not
exceed 100N at start-up.
