Step 5. Turn the TTS Amplitude control knob to the minimum amplitude.
Step 6. Set TTS to operate in the Sensivity Mode, select Displace ment Sensor Type and to read sensi-
vity in Mils. (Test Page A)
Step 7. Press the 100 Hz Frequency Control buon.
Step 8. Press the RUN/STORE buon.
Step 9. Set the Amplitude Control to as indicated in the Sample Data Sheet (from 2 to 5 Mils) and verify
sensivity is within the require range. (See Table 5-4)

Step 10. Turn the Amplitude knob counterclockwise unl the knob stops. Regap the probe to verify
sensivity over the probes specied calibraon range.
Step 11. Repeats steps 9 and 10 unl all data points listed in the Sample Data sheet have been veried.
