First Zero?1. Remove all weight and press [TARE] or [ENTER].2. From the Enter Load prompt key in the first calibration point and press [TARE]or [ENTER].3. From the Add Load prompt add the weight of the first calibration point andpress [TARE] or [ENTER].4. For calibration points 2 -5; Simply add the weight which you want to use for thenext calibration point, then key in the value of the applied weight and press[TARE] or [ENTER]. You may wish to add weight until the displayed weightdiffers from the actual applied weight and then perform the next calibration atthat point.Reset Cal1. Press [TARE] or [ENTER].2. From the First Zero?prompt remove all weight and press [TARE] or [ENTER].3. From the Enter Load prompt key in the first calibration point and press [TARE]or [ENTER].4. From the Add Load prompt add the weight of the first calibration point andpress [TARE] or [ENTER].5. For calibration points 2 -5; Simply add the weight which you want to use for thenext calibration point, then key in the total applied weight and press [TARE] or[ENTER]. You may wish to add weight until the displayed weight differs fromthe actual applied weight and then perform the next calibration at that point.Up to five calibration points may be established using this procedure. However if fewercalibration points are required, simply press [TARE] or [ENTER] without entering avalue at the PntX prompt.After the last point is established, the indicator will prompt with Cal ~ Good? Press the[TARE] or [ENTER]. key to accept the calibration or press [ZERO] or [CLR] to backupand redo the last point as described below.If you make a mistake at any point in the linearization process, simply press the [ZERO]or [CLR] key. The indicator w backup one step in the procedure to the previouslinearization point.After the linearization has been completed, the changes must be saved by pressing[TARE] or [ENTER] at the Enter = Save prompt. Otherwise the previous calibration datawill remain in effect.Examining Calibration ResultsIf Multi-Point Linearization is enabled (P119), the ten Parameters P61130 thru P61139show the calibration weights used and the resulting calculated factors. Otherwise themessage Not Used is displayed.Establishing a SpanOnce a zero reference has been established, the Model 350/355 I.S. displays Enter ~Load and awaits the entry of a span (test load) value. This value may be entered beforeor after the test load has been applied.124Model 350 I.S. and Model 355 I.S. Service Manual
