Make the necessary settings to suit specific needs. 3.5.1 Calibration Press the Menu button and select CALIBRATION. Press the enter button, the CALIBRATION screen is displayed. Explorer Pro balances offers a choice of five calibration methods: Internal Calibration, Autocal Calibration, Span Calibration, Linearity Calibration and User Calibration, Linearity, Span and User calibration are disabled for Type Approved/LFT balances Class II and Class III. CALIBRATION Internal AutoCal AutoCal Delta Span Linearity User User Cal Weight Cal Test Exit IMPORTANT ! DO NOT DISTURB THE BALANCE DURING CALIBRATION. : Off (d): 0 (g): 500.00 AutoCal: On, Off (default is On) Explorer Pro balances equipped with internal calibration also contain AutoCal. When AutoCal is set ON, the balance performs a self calibration when a measured predefined delta temperature change occurs. After calibration, the display returns to the last application mode. Environmental conditions must be met for the AutoCal to be successfully completed. AutoCal Delta: -100 - +100 (default is 0) Explorer Pro balances equipped with internal calibration also contain AutoCal Delta. AutoCal Delta allows the internal calibration mass value to be adjusted. This permits calibrating the balance using an external mass which is traceable to a certified standard. Perform the internal calibration procedure. After the calibration is completed, zero the balance. Place a certified mass equal to the span calibration value of the balance. EN-24 Explorer Pro Compare the reading on the balance to the expected weight being used. If the reading is above the expected weight, the delta entered in digits is negative. If the reading is below the expected weight, the delta entered in digits is positive. See following example: Actual Weight Reading: 200.0014 Expected Weight Reading: 200.0000 Delta Weight (d): 0.0014 Delta weight in Digits: -14 Recalibrate using internal calibration. After calibration, place the certified mass on the pan and see if the mass agrees with the displayed value. If not, repeat procedure until internal calibration reading agrees with the certified mass. Span Calibration: Span calibration utilizes two calibration points, one at zero load and the other at specified full span. See following table. CALIBRATION MASSES LINEARITY SPAN ONLY CAPACITY MASSES MASSES 62 g 20g/50 g 50 g 162 g 50g/150 g 150 g 110 g 50g/100 g 100 g 210 g 100g/200 g 200 g 410 g 200g/400 g 400 g 510g/610 g 200g/500 g 500 g 1550 g 500g/1500 g 1500 g 2100 g 1000g/2000 g 2000 g 4100 g 2000g/4000 g 4000 g 6100 g 2000g/5000 g 5000 g 8100 g 4000g/8000 g 8000 g It is recommended that masses must meet or exceed ASTM Class 1 Tolerance. Calibration masses are available as accessories. Additional calibration values to be used are shown on the display screen. The best accuracy is achieved using the mass closest to the full span value. After calibration, the display returns to the last application mode. Linearity Calibration: Linearity calibration utilizes three calibration points, one at zero load and two at specified calibration masses. This method minimizes deviation between actual and displayed weights within the balance's weighing range. After calibration, the display returns to the last application mode. User Calibration: User calibration is used when it is desired to calibrate the balance using a user defined mass. The user defined mass value has to be entered in the User Cal Weight. After calibration, the display returns to the last application mode. User Calibration Weight: 25%-100% of capacity (default is Span) Defines the mass value for User calaibration. The user calibration may now be done with the mass selected. Cal Test: Calibration test feature allows a check of a known calibration mass against the last stored calibration information in the balance. The display indicates the difference in weight between calibration mass placed on the pan and the previous weight value which was stored in the balance. After Cal Test, the display returns to to the last application mode. 3.5.2 Balance Options Press the Menu button, and select Balance Options. Press the Enter button.
