6 Scroll to page 2.
7 Record the ‘Current Setpoint’ value: _______________mA
8 By specification, 75% of the value recorded in step 7 is the Anticipated Level 3 current. Calculate and record
this value by
multiplying the step 7 value above, by 0.75. _______________mA
9 Scroll to page 17.
10 Turn the volume knob fully to the left (counter-clockwise).
11 Press the “TEST” key repeatedly until “Value Not Accepted” is flashed on the display. Fail_____ Pass_____
The unit is now intentionally uncalibrated. This can be verified by scrolling to page 21 and inspecting the
“Current Write Cal:” The value should be 5060.
Fail_____ Pass_____
12 Put the generator into BME Ready state by pressing the ‘STANDBY’ Key.
13 Ensure the test tip is prepared to activate in air and is not in contact with anything during activation.
14 Activate at level 3 by pressing the MIN footswitch or hand switching adapter buttons.
15 After the pre-run test is complete, continue activating at level 3, and measure the VAC RMS across the series
combination of R233 and R234, using the Digital Multimeter (DMM). Record the value to four digits of
precision.
_______________mA
16 Deactivate the hand piece by releasing the foot switch or hand switch button.
17 Put the generator into BME Standby State by pressing the ‘STANDBY’ Key.
18 Scroll to page 17.
19 By turning the volume knob, dial in the value read on the DMM in step 16. (a number is displayed on the
LCD, which changes as the knob is turned).
20 Press the “TEST” key one time (only one time).
“Value Accepted” should flash.
Fail_____ Pass_____
21 Power off the unit for at least 5 seconds.
22 Power up the generator into BME Mode.
23 Put the generator into BME Ready State by pressing the ‘STANDBY’ Key.
24 Ensure the test tip is prepared to activate in air and is not in contact with anything during activation.
25 Activate at level 3 by pressing the MIN footswitch or hand switching adapter buttons.
26 After the pre-run test is complete, continue activating at level 3, and measure the measure the VAC RMS
across the series combination of R233 and R234, using the DMM as in step 16 above. Record the value to
four digits of precision:
_______________mA
27 Verify the current in step 26 is within 1% of the value calculated in step 8. If not, carefully re-execute this test
procedure again (up to three times.)
Fail_____ Pass_____
28 Power OFF the generator for at least 5 seconds and continue to the CALIBRATION TWO procedure.
