Periodic Performance Testing
The System 5000™ should be tested for correct
performance at least once every year. Every unit
is supplied with a serialized Production Test Data
Sheet that tabulates the results of the factory tests
that were performed on the unit. This data is
supplied so that it may be used as a reference for
subsequent tests. Recommended periodic perfor-
mance tests are listed in the following sections.
4.6.1 Chassis Ground Integrity
Connect a standard ohmmeter between the
earth ground prong on the power plug and the
Equipotential Ground Connection. Compensate
for lead resistance. Confirm less than 0.2 ohms
resistance is measured.
4.6.2 Displays, Alarms and Commands
Perform the Preliminary Functional Test procedure
described in section 2.3.1 of this manual to verify
proper operation of displays, alarms and com-
mands.
4.6.3 Output Power
1) Equipment Requirements:
a) Monopolar Footswitch
b) Bipolar Footswitch
c) Commercial ESU Tester (e.g. Dynatech
454A or equivalent) with 50 and 300
ohm loads for bipolar modes and a 500
ohm load for monopolar modes.
Note: Micro Bipolar is particularly sensitive to the
load resistance. A 50 ohm load should be used for
checking power to obtain the best results.
2) Use test leads to connect the ESU tester to
the unit’s return electrode output and the
footswitch controlled active output. Set the
Load resistance per mode as indicated in
Tables 4.1 and 4.2.
3) Perform the monopolar power tests indicated
in Tables 4.1 and 4.2. The acceptance range
is given in both Watts and Amps to accom-
modate available test equipment. It is not nec-
essary to test for both power and current.
