4-9
• GLONASS S/N ratios are good (Table 4-2).
• Oscillator’s frequency offset is less than three ppm.
• Oscillator's Allan Variance is better than 2.7e-10.
• Continuous tracking time is more than 15 minutes.
In EIM, the STAT LED blinks seven times per cycle. Each
blink could be orange, red, or green.
• Orange – information for test unavailable.
• Green – receiver passed the test.
• Red – receiver failed the test.
1. To switch to EIM, press and quickly release (within one
second) the FN key on the MINTER.
2. Watch for the delimiter double-blink. With good
receiver, antenna, and observation conditions, all blinks
should be green within 15 minutes of powering on.
• Green – ok
•Orange – wait
• Red – some tests failed
3. To switch back to normal, press the FN key.
