Calibration
Section 8.0
8.1 Introduction
This calibration procedure provides an organized
and comprehensive alignment method to ensure
continued unit performance and safety. Most
unit alignments can be accomplished using com
-
monly used test equipment, however a few system
alignments require equipment not ordinarily avail
-
able. All system alignment parameters have been
calibrated at the factory and system calibration
parameters that require specialized equipment are
identified as “Optional” steps in the procedure.
CAUTION: Do not attempt system calibration
unless the proper test equipment is available.
Contact Conmed Corporation Technical Services
Department with any questions regarding system
calibration, operation or safety issues.
The alignment procedure should be performed
in the same order as listed in this service manual.
Refer to Figure C-1
for the location of the PCB
assemblies.
8.2 Equipment List
8.2.1 Standard Equipment List
• ESU Analyzer (500 ohm & 100 or 125 ohm)
• Voltmeter or Digital Volt Meter (DVM)
• Dual Channel Oscilloscope
• Current Meter (10A rating)
8.2.2 Optional Calibration Equipment List
• 1000:1 Oscilloscope Probe(s)
• Mass Flow Meter - calibrated for argon
8.2.3 Test Leads & Adaptors
Note: See Figure 2.1 for drawings of Test Leads
and Adaptors.
• Dispersive Electrode Adaptor: Made from a
dispersive electrode cord that can be used
on the System 7550™, with a banana jack in
place of the dispersive electrode.
• Dispersive Electrode Cord: Dispersive elec-
trode cord with the dispersive electrode cut
off. Strip the insulation approximately .25”
off of both conductors.
• Test Leads (2)
• ABC Adaptor: Required to calibrate ABC
power. To make this adaptor, use a dispos
-
able ABC accessory. Cut the nozzle off,
and in place of the nozzle, connect a banana
jack. This adaptor should not be used with
argon flow as it occludes the flow unless small
exhaust ports are cut into the adaptor.
• ABC Accessory: To measure argon flow rates,
an ABC accessory is required, such as a Triple
Option Handcontrol.
8.3 Calibration Set-Up
• Remove the two screws located on either side
of the top cover. Lift the cover and secure the
hinge to hold the cover in the raised position.
• Remove the cover from the card cage to allow
access to the two PCB assemblies (A1 and
A4) within the card cage. See Figure C-1.
• Attach a dispersive electrode cord to the dis-
persive electrode connector.
• Calibration is easier to perform when using
the footcontrol switches for activation. If
available, connect the three (3) footcontrols to
the receptacles located on the Cart.
• If footcontrols are not available, connect a
Triple Option Handcontrol to the Monopolar/
Beam Handcontrol receptacle to allow activa
-
tion in Cut, Coag, & ABC.
• Connect a tank of Argon gas. Ensure the
tank is securely fastened to the Cart with the
supplied strap. Turn the tank valve counter-
clockwise to open the tank valve. Verify at
least 200 psi of pressure registers on the pres
-
sure gauge located on the back of the cart.
8.4 A.R.M. Calibration (HS/A.R.M.
Assembly - A11)
8.4.1 10 Ohm A.R.M. Calibration
• Place 10 ohms across the two leads of a disper
-
sive electrode cable.
