This circuit shows an ICL8013 (refer to Fig. 3-15) connected as a basic divider. Use the following trim procedure.1. Set the trim pots (Fig. 3-15D) at mid-scale by adjusting the voltage on pins 7, 9, and 10 for 0 V.2. With ZIN= 0V, trim Z0s to hold the output constant as XIN is varied from -10 V through -1 V.3. With ZIN= 0 V and XIN =10.0 V adjust Yos for zero output voltage.4. With ZIN=XIN (and/or ZIN =-XIN) adjust Xos for minimum worst-case variation of output as XIN is varied from -10 V to -1 V.5. Repeat steps 2 and 3 if step 4 requires a large initial adjustment.6. With ZIN = XIN (and/or ZIN = -XIN), adjust the gain control until the output is the closest average around +10.0 V (-10 V for ZIN =-XIN) as XIN is varied from -10 V to-3 V.
