Step 31. Press the Cursor buon to move to the Correcon Factor Field.

Step 32. Press the Run buon.

Step 33. Turn the Frequency Lock Nut counterclockwise to unlock the Frequency Knob.

Step 34. Turn the Frequency Knob clockwise to see if the frequency increases in value. Mark this step on

the Check O Sheet.

Step 35. Set the frequency to 100 Hz.

Step 36. Turn the Amplitude Lock Nut counterclockwise to unlock the Amplitude Knob.

Step 37. Turn the Amplitude Knob clockwise to see if the amplitude increase in value. Mark this step on

the Check O Sheet.

Step 38. Set the Amplitude to 3 G’s and press the SPACE buon to calibrate.

Step 39. Record the Correcon Factor on line 26 of the Check O Sheet.

Step 40. Press the down arrow. The CALIBRATE D screen appears.

Step 41. Press the Cursor buon to move to the second line on the screen which reads REF ONE INTEG

(Reference with One Integraon).

• Repeat Steps 30 through 39.

• Press the down arrow buon. The CALIBRATE E screen appears.

Step 42. Press the Cursor buon to move to the second line on the screen which reads REF TWO INTEG

(Reference with Two Integraons).

• Repeat Steps 30 through 39.

• Press the down arrow buon. The CALIBRATE 1000 F screen appears.

Frequency Calibraon Procedures

Step 43. Press the Cursor buon to move to the second line on the screen which reads FREQ. CAL (Fre-

quency Calibraon). Enter the sensivity value that corresponds to the frequency to be set (1000 Hz).

You can get the sensivity value from the Standard Accelerometer documentaon.

• Press the RUN buon.

• Set the frequency to 1000 Hz and the amplitude (GIR) to 1.0 G.

• Press the SPACE buon to calibrate the frequency.

• The Correcon Factor should not be less than .85 or greater than 1.15.

• Record the Correcon Factor on line 27 of the CHECK-OFF Sheet.

• Press the down arrow buon. The CALIBRATE 2000 G screen appears.

Step 44. Press the Cursor buon to move to the second line on the screen which reads FREQ. CAL (Fre-

quency Calibraon). Enter the sensivity value that corresponds to the frequency to be set (2000 Hz).

You can get the sensivity value from the Standard Accelerometer documentaon.

• Press the RUN buon.

• Set the frequency to 2000 Hz and the amplitude (GIR) to 1.0 G.

• Press the SPACE buon to calibrate the frequency.

• The Correcon Factor should not be less than .85 or greater than 1.15.

• Record the Correcon Factor on line 28 of the CHECK-OFF Sheet.

• Press the down arrow buon. The CALIBRATE 3000 H screen appears.
