Notes:
1. The product of C4 and R
T
have a direct effect on gain and therefore directly affect temperature compensation.
2. C

Range; 20 pF to 0.2 F.
3. R
T
Range; 100 k to 500 k.
4. The Ic must be protected from transients above 60 V and reverse battery conditions.
5. Additional filtering on FREQ
IN
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.
