Checks install place and connection prior to setting, caution the following
instruction.
* No power ON/OFF switches.
Cautions to operate from the voltage supply the moment.
* Input/output part are not isolated electrically. Use the specific cable to protect
indicator against over voltage and current and indicator get to the ground connection
* Setting lock mode for system and data protection
* Do not internal disjointing and adjustment voluntarily because the indicator is
composed of electron component and P.C.B circuit to sharp at the static electricity .
DACELL is not liability for mistake to use that change a property voluntarily, change
design, adjustment voluntarily, user carelessness cause defect.

5) AUTO ZERO mode
Initialize sensor and indicator.
Execute this mode at unlock mode.
Execution process (display : operation mode)
(1) Sensor : no load.
(2) Voluntary data display.
(3) Press key and key at the same time.
Zero display (ex : 0, 0.0, 0.00, 0.000)
(4) This data is memorized to indicator though power turn off.
(5) If operate mode with input signal to remain, this point is memorized zero point.
6) AUTO CALIBRATION mode
Convenience to use when do not know calibration data of sensor or
displayed the measurement value differently.
(1) Adjust zero point of indicator.
(2) Apply known load to sensor. Large load is high safety.
(3) Press key: F.S and CAL L.E.D turn on at the same time.
(4) As example table, 100.05 or 99.05 will blink.
(5) After correction of 100.00 using key and key, press key.
(6) 100.05 is display correction of 100.00.
(7) At this time, cal data is corrected minutely.
(8) If corrected cal data is over limits of 2-4), correct of DIP S/W setting and again
set the auto calibration.
EX) At sensor Supply : 100.00 kg/㎠
Display : 100.05 or 99.05 kg/㎠
Adjustment : 100.00 kg/㎠
