Step 11. Use Input Test Cable (Prt. # 0215-0097-01). Connect the Calibraon Capacitor (Model 2947B-2)
between the synthesizer output channel 1 and the CHARGE CHANNEL input (J4) BNC on the Input Test
Cable.
Step 12. Repeat steps 5 through 8. Then disconnect the synthesizer and calibraon capacitor from the
TTS.
Step 13. Record the new Correcon Factor number on line 12 of the Check-O sheet.
Displacement DCCalibraon
Step 14. Use the Coaxial Cable (Standard BNC to BNC) and connect the synthesizer Channel 1 output to
the Displacement (J5) Input on the Input Test Cable.
Step 15. Set the synthesizer for 1V 0-peak sine wave at 100 Hz.
Step 16. Press the RUN buon to see the current input signal. The desired reading is 1000.00 ±.1%.
Step 17. If the reading is not between 999.00 and 1001.0, press the SPACE buon. The unit should
adjust itself within the limits.
Step 18. Record the Correcon Factor number on line 17 of the CHECK-OFF Sheet.
Step 19. Press the down arrow once. The DISPLACEMENT DC screen appears.
Step 20. Set the synthesizer for wave form DC and set the voltage to - 10 volts.
Step 21. Press the RUN buon to see what input signal the TTS currently reads. The desired reading is
-10000 +- .1%.
Step 22. If the reading is not between -9990 and -10010, press the SPACE buon. The unit should adjust
itself to within the limits.
Step 23. Record the Correcon Factor number on 21 of the CHECK- OFF Sheet.
Step 24. Disconnect the synthesizer from the displacement channel (J5).
Step 25. Press the down arrow once. The CALIBRATE C screen appears.
REF Channel No Integ Calibraon
Step 26. Mount the Transfer Standard Accelerometer (Model 2010M12) onto the TTS Reference Ac-
celerometer. Apply a lile vacuum grease on the surface of the Standard Accelerometer and the surface
of the Reference Accelerometer. (See Installaon instrucons for Installing Accelerometers in Chapter 3).
Step 27. Connect the Test Cable (Prt. #0215-0097-01) to the Transfer Standard Accelerometer and to the
Channel A (J1) input of the Input Test Cable.
Step 28. Get the sensivity value for the Transfer Standard Accelerometer from the Calibraon Docu-
ments that come with the standard accelerometer.
Step 29. Press the Cursor buon to move to the second line on the screen which reads REF NO INTEG
(Reference with no Integraon).
Step 30. Use the Le Arrow on the number keypad to remove the numbers. Use the number keypad to
enter the sensivity value from the Standard Acelerometer Documentaon.
