CALIBRATION MODE:
Trinity can be calibrated periodically by connecting it to the 10M Atomic Clock. This is not
something that necessarily needs to be done very often, but if desired here's how to do it...
Connect 10M to Trinity as normal.
Power on both devices, and wait for 10M device to reach operating temperature.
Set Trinity SOURCE knob
to OVEN, and be sure that the ATOMIC LED
is lit.
Wait for 1 minute to allow the units to stabilize.
Press Display button
, and then Varispeed button
. Trinity is now in calibration
mode.
To proceed with calibration, press the SAMPLE RATE knob (4). Trinity is now
calibrated to better than +/- 0.001 ppm accuracy.
Exit calibration mode by pressing the INFO button
.
Note: The middle line of the display is the only thing you need to look at when in CAL mode.
If this is stable at +/- 0.5 ppm or greater then it is worthwhile to proceed with calibration. If
the display is not stable, please wait for a minute or two until it stabilizes before deciding
whether calibration is needed or not.
