SYNC-TIME MEASUREMENTS (cont)

Set DATA ON/OFF to ON:

Display will rapidly (almost instantly) advance count (1000 counts per second).

When TD-1065 has acquired sync, it will output data to the TS-3981. The TS-3981 ACTIVITY

indicator will light, and display count will stop advancing.

The display, at the time it stops advancing, is the number of milliseconds it took the TD-1065

to acquire sync, typically 5 to 20 milliseconds. Readings of 0 to 4 milliseconds are due to

noise and are erroneous.
