A ±3 ppm minimum via internal mechanical adjust
positive slope.
B ±3 ppm minimum via external voltage, 0 to +5 Vdc
F No Frequency Adjust. Standard option for ±1 ppm
and ±4.6 ppm for 10 years units. However, this
option is available with all Stability options. No user
adjustment is needed. Unit is Plug-N-Play.
Note: This option is ideal for high volume applica-
tions where minimal set-up and testing is desired.
