To program the decimal point observe the following indications. Touch the “5d.p.” key with the instrument in measuring mode. A decimal point will light up. In order to move this point touch the indicated key until the desired point is reached and than confirm with “FS ↵“ 2.3 RECOVERY TARA FUNCTION For “Recovery Tara” we mean a function that when in use zeroes the instrument readings. The Recovery Tara function can be enable from “Reset / Exit” key or shortcircuiting terminals 4 and 5. At the moment when the terminals 4 and 5 are short circuited or “Reset / Exit” key is pressed, zero is displayed...

2.5.2 PRACTICAL EXAMPLE In this example we consider an application for which it is not possible to make a precise calculation of the potentiometer variation, it therefore being necessary to use empirical methods. Let us suppose a linkup of the potentiometer with the instrument and to be able to assign two fixed points to the course of the transducer A and B. The system calibration requires the following data. POINT A = 250 POINT B = 1500 switch on the instrument with the calibration values set-up with these numbers: ISI = 0000 ISL = 0000 FSI = 9999 FSL = 9999 OFFS = 0000 Position the potentiometer...
