5. Calibration This weighing indicator, converts an input voltage from a load cell to the "mass" value, and displays it. Calibration is the adjustment function so that the scale (indicator) can weigh correctly. 5.1.1. Items of Calibration Mode There are seven items in the calibration function. Basic Items The minimum division ............... Setting the weighing interval. The maximum capacity ............. Setting the maximum display. Zero calibration..........................
Calibrate the scale, if it is moved to another location or the environment has changed. It is not necessary to set the gravity acceleration correction, when calibrating the scale with a calibration mass at the place where the scale is used. Enter the stable weighing data while the MD mark is turned off. If unstable data is used, it may cause a weighing error. Arrange the condition using the F00 filter function. The span calibration needs the zero calibration data.
Step H Gravity compensation function. Perform this function after span calibration. 5.2.2. Preparation Step 1 Keep the following conditions to calibrate the scale (indicator) correctly. Maintain a constant temperature, stable power and stable input voltage from the load cell. Avoid direct sunshine and in the neighborhood of an air conditioner. Do not install the scale (indicator) where there is a strong magnetic field. Step 2 Turn the display on during 10 minutes. 5.2.3.

5.3. Weighing Range Function The weighing range function can select "single range", "dual range" and "triple range". Specify each weighing interval (division) for the multi-interval instrument. Each weighing interval is displayed according to a net value or gross value. Caution Using a single range, it is not necessary to perform this function. Perform the zero and span calibration after this function. Example 1 The gross display. Specified parameters: First range Range = 20.00kg, division 0.
5.3.1. Setting Division and Range Consider the following rules to design the weighing range. Rule 1 Select the division and range of each weighing range so as to fit the following inequality. The first range < the second range < the third range The division of next weighing range is automatically set bigger than division of lower weighing range. And the division can change. Rule 2 When setting the dual range, the upper limit value of the second range becomes the maximum capacity.

5.4. Digital Linearization Function Even if the zero and span calibration have been completed, there may still remain some linearity deviation by the performance of the weighing unit. The digital linearization function can rectify and reduce the linearity deviation using weighing points during the zero and capacity setting. Up to three weighing points can be specified. Caution This function does not improve repeatability and hysteresis. Use the mass on the condition that lnr 1 < lnr 2 < lnr 3.
5.5. Gravity Compensation Function If the scale is used at the calibration location, it is not necessary to perform this function. It may cause a weighing error, if there is a difference of gravity acceleration between the installed location and calibration location. This function specifies these gravity accelerations and corrects span error. Caution The decimal point is not displayed in the function. Ex. 9798 = 9.798 m/s2 Step 1 Press the CAL key in normal weighing mode. The is displayed for two seconds.
