4.2.6 RF Leakage from Inactive Outputs
Equipment: Same as in Section 4.2.5
Procedure:
1. Set the unit for full power Monopolar Coag
and Bipolar Coag. Connect the 200 ohm, nonin-
ductive resistor in series with the fused RF
ammeter. One at a time, connect that series com-
bination between the RETURN ELECTRODE
Connector and each RF output terminal shown
in Table 4.3, and activate the unit using the corre-
sponding command. Confirm that no meter read-
ings exceed the specified maximum. Hand control
coag activation is accomplished by connecting a
jumper between the center black jack and the red
jack of the hand controlled active connector.
>WARNING<
HAND CONTROL ACTIVATIONS
SHOULD BE KEYED USING 3'' OR LESS
WELL INSULATED JUMPER(S). USE OF
AN INSULATING ROD TO INSERT THE
JUMPER IS ADVISED TO PREVENT RF
BURNS.
CAUTION: To avoid destroying the meter,
never activate output terminal connected to
the meter.
2. Disconnect the meter and resistor from the
unit. Turn unit Power Switch OFF.
4.3 RECALIBRATION
Recalibration is necessary if the Power or ARM
checks indicate that the unit fails to meet specifi-
cations. Make sure that the calibration problem is
not due to a component failure first, however.
Attempts to "calibrate around a failure" may result
in failure of the Calibration Quality Tests and the
need to operate the unit in Diagnostics Mode
until the problem is corrected, followed by a
complete recalibration. Common failures which
cause low power output are usually found easily
by checking for blown fuses in the Power
Amplifier section, for instance. See Section 4.5
for further guidance on troubleshooting.
