Chapter 13 - Generator Calibration
Calibration Two (Read Current Calibration)
This section describes the requirements for calibrating the monitored (read) current level of the GEN04
Generator.
Note: “Power up into BME Mode” includes taking the following steps – which are also contained in the service
manual (included here for reference):
• Power down unit
• Wait 5 seconds
• Power up Unit while simultaneously holding the “STANDBY” and “DOWN ARROW” keys
Procedure:
1 Power up the generator into BME Mode
2 Scroll to page 2.
3 Record the ‘Current Setpoint’ value. _______________mA
4 By specification, 75% of the value recorded in step 3 is the anticipated Level 3 current. Calculate and record
this value by
multiplying the step 3 value above, by 0.75. _______________mA
5 Put the generator into BME Ready State by pressing the ‘STANDBY’ Key.
6 Ensure the test tip is prepared to activate in air and is not in contact with anything during activation.
7 Activate at level 3 by pressing the “MIN” footswitch or “MIN” hand switching adapter buttons.
8 Continue activating the generator at level 3 for at least 1 second after the pre-run test is complete.
9 Deactivate the hand piece by releasing footswitch or hand switching adapter buttons..
10 Put the generator into BME Standby State by pressing the ‘STANDBY’ Key.
11 Scroll to page 18.
12 Press the ‘TEST’ key one time (only one time) to accept the calibration current value.
13 The text “Value Accepted!” should flash if the calibration procedure was successful. Fail_____ Pass_____
14 Record the current displayed on the screen. _______________mA
15 Power the unit off for at least 5 seconds.
16 Power the unit into BME Mode.
17 Enter BME Ready State by pressing the “STANDBY” Key.
18 Ensure the test tip is prepared to activate in air and is not in contact with anything during activation.
19 Activate at level 3 by pressing the “MIN” footswitch or “MIN” hand switching adapter buttons.
20 Continue activating the generator at level 3 for at least 1 second after the pre-run test is complete.
21 Deactivate the hand piece by releasing footswitch or hand switching adapter buttons.
22 Go to BME Standby State by Pressing the “STANDBY” Key.
23 Scroll to page 18.
24 Record the ‘I (LEVEL 3)’ current displayed on page 18. _______________mA
25 Verify that the reading is within 1% of the value calculated in step 4. If not, carefully re-execute both
CALIBRATION ONE & CALIBRATION TWO procedures again (up to three times.)
Fail_____ Pass_____
26 Power OFF the Generator.
