Temperature Stability
Improved accuracy/stability available on some models. For
example, for ±7 ppm over 0°C to +50°C and for ±10ppm
over 0°C to +70°C. Improvement is also available over wider
temperature ranges. Please contact factory.
E= set to ±1 ppm via external capacitor (< MHz in CO-432 and <240MHz in CO-434/37
