12.4.5.8. Calibration of cut module power (Service function 13)
If the power in cut mode during soft- and force coagulation is generally too high or too
low, a calibration can be performed. This is done by choosing service mode 13, changing
the parameter into the desired direction, leaving service mode and checking the cut
power at 210W with 200
Ω load. Then enter service mode 13 again, readjust, if necessary,
and store the parameter.
After service function 13.1 the fine adjustments for force and blend can be done with 13.2
and 13.3in the same way as for 13.1.
Sub-function Parameter adjustment Power set
1 Cut mode, step 4 210W
2 Force, step 5 100W
3 Blend, step5 250W

12.4.5.10. Check of power measurement (Service function 14)
This mode shows the delivered power in the parameter display decimal in Watts. A
comparison with a RF-power meter informs about correct functioning. See also "Safety
technical checks".
Sub-function Calibration selected power (W)
1 Cut-power low 40
2 Coag-power low 40
3 Cut-power high 210
4 Coag-power high 120
5 Cut-pulse-power high 40
Purpose of calibration is the adjustment of internal measuring circuits by means of
externally measured values. This is done by connecting a power meter in position 200
Ω ,
setting Cut to 40W, and selecting step 14. On activation the measured power value is
shown in the Coag display resp. Gas display (Arco 1000). A correction can be made by
means of the arrow keys. Indicated and externally measured values should correspond.
The calibration has to be performed for all sub-functions 14.1-5 as described above.
12.4.5.11. Indication power supply voltage and current (Service function 15)
The power supply voltage and the power supply current of the previously selected power
step is indicated in hexadecimal.
-Sub-function 1: power supply voltage
