DISCLAIMER: THIS PROCEDURE PROVIDED "AS IS" AND
WITH POSSIBLE FAULTS. USER MUST VERIFY BEFORE USE.
NEITHER PROVIDER NOR WEBSITE ASSUMES ANY
RESPONSIBILITY FOR ITS USE.

1. General
Applies to Valleylab models SSE2K, SSE3 models.

2. Reference Documents
Valley Lab Maintenance Notes - see Appendix.
Valley Lab SSE3 “Complete Instruction Manual”

3. Tools / Fixtures / Labels

 Electrosurgical Analyzer: ex: Dempsey 443.
 Insulated wire set terminated with banana plugs.
 Hand Control Pencil, footswitch.
 Safety Tester

4. Basic PM Procedure

4.1. Inspection

Check unit for any damage, especially the front
connectors, the power cord and the footswitch with
its cable.

SSE2 ESU

SSE3 ESU

4.2. With no accessories plugged in, turn on unit. For the

SSE2, either the monopolar or bipolar lamp will
illuminate; press in the light switch that is off; it
should come on. For the SSE3, include the extra
mode lamps.

4.3. Setup

Connect analyzer to ESU using a handcontrol pencil;
wire the pencil chuck to the analyzer active (this
simultaneously will check handcontrol sense
circuits.) Connect a banana type lead between the
generator’s patient jack over to the same on the
analyzer. Set analyzer load to 300 ohms if available.
Press in the monopolar switch-lamp. Set the Blend
switch to pure cut.

4.4. Cut Mode

With both dials at zero, key the unit in Cut mode, and
note audible tone. The cut lamp will not illuminate until power is turned up past
approximately Dial = 1. Gradually turn power to max dial and note power into
analyzer. Refer to table for acceptable results. For reference, wattages at other loads
are listed.

DEMPSEY 443 ANALYZER

BC GROUP ESU-2000A ANALYZER

4.5. Blend Mode

For each of three blend modes (SSE3 only), repeat the protocol for Cut, and note the
max dial output power in the table below.

4.6. Coag Mode

With both dials at zero, key the unit in Coag mode, and note distinct audible tone. The
coag lamp not illuminate until power is turned past approximately Dial = 1.
Gradually turn power to max dial and note power into analyzer. Refer to table for
acceptable results. For reference, wattages at other loads are listed.

4.7. Bipolar Mode

Press in the bipolar switch/lamp. Put Cut mode selector in Pure Cut. Connect the
analyzer to the two outside socket pins of the generator’s bipolar output connector.
Set analyzer load to 100 or 125 ohms. With both dials at zero, use the footswitch to
key the unit in Cut mode, and note distinct audible tone. Gradually turn power to max
dial and note power into analyzer. Refer to table for acceptable results.

Repeat, but using the coag side of footswitch. Refer to table for acceptable results.

POWER OUTPUTS FOR VARIOUS LOAD @ Max Dial*
MODE/LOAD R=500 R=300 R = 125 R=100
Cut 210 300 +/- 10% 270
Coag 110 115 +/- 10% 100

Blend 1
Blend 2 200
Blend 3 200

Listed blend
wattages are from
the SSE3 manual.

250

Bipolar Cut NA NA 55 60
Bipolar Coag NA NA 22 25

* Note: The wattage levels at 300 ohms are listed in SSE3 manual; powers at other loads
were derived from the published impedance curves of the Force series generators.

4.8. Verify volume adjust on back of unit.

4.9. Using the safety tester, check that line leakage with ground open is less than 50 uA.

4.10. Using the safety tester, check that ground lead resistance is less than .15 ohms.

4.11. REM – these units do not have the REM pad sensing feature.
