LEDs indicate when the gate is armed, and whether displayed numbers are in kHz or MHz, and when register overflow occurs. | LEDs indicate when the gate is armed, and whether displayed numbers are in kHz or MHz, and when register overflow occurs. | ||
A standard internal 1 MHz clock is provided with 1 × 10<sup>-5</sup> (10 ppm) stability, but an "Option 01" 5 MHz clock is also available which provides 5 × 10<sup>-7</sup> (0.5 ppm stability. That option includes additional circuitry to divide the clock frequency by 5 in order to obtain 1 MHz. | A standard internal 1 MHz clock is provided with 1 × 10<sup>-5</sup> (10 ppm) stability, but an "Option 01" 5 MHz clock is also available which provides 5 × 10<sup>-7</sup> (0.5 ppm) stability.
