1. The product of C4 and RT have a direct effect on gain and therefore directly affect temperature compensation.

2. CCP Range; 20 pF to 0.2 mF.

3. RT Range; 100 kW to 500 kW.

4. The Ic must be protected from transients above 60 V and reverse battery conditions.

5. Additional filtering on FREQIN lead may be required.

6. Gauge coil connections to the IC must be kept as short as possible (≤ 3.0 inch) for best pointer stability.
