1. Introduction
This chapter describes the METRON QA-ES Electrosurgical A a-
lyzer, i cludi g its features a d specificatio s.
1.1 QA-ES Descrip-
tion
The METRON QA-ES Electrosurgical A alyzer (QA-ES) is a preci-
sio i strume t desig ed to perform tests o high-freque cy electro-
surgical u its (ESU) i accorda ce with atio al a d i ter atio al
sta dards, a d is desig ed to be used by trai ed service tech icia s.
Tests i clude:
•automatic power distributio measureme t;
•crest factor measureme t;
•RF leak measureme t, a d;
•retur electrode mo itor (REM) test
Testi g is accomplished by measuri g the ESU output agai st test
loads that are set a d adjusted i the QA-ES. The QA-ES ca auto-
matically execute a power distributio test with a load resista ce
ra gi g from 10 ohms to a maximum of 5200 ohms. The automatic
measuri g of the QA-ES, comprisi g crest factor measureme ts
with a ba dwidth of 10 MHz, e sures that the test result is reliable
a d reproducible.
Test results, show i the QA-ES’s LCD display, ca be pri ted out
directly, or tra sferred to a PC via the PRO-Soft QA-ES test auto-
matio software. PRO-Soft lets you desig test protocols, remotely
co trol the QA-ES, a d store the test results.

2. Installation
This chapter explai s u packi g, receipt i spectio a d claims, a d
the ge eral procedures for QA-ES setup.
2.1 Receipt, Inspec-
tion an Return
1. I spect the outer box for damage.
2. Carefully u pack all items from the box a d check to see that
you have the followi g items:
QA-ES Electrosurgical A alyzer (PN 14010)
E-I put Measuri g Cable -- Black (PN 11411-B)
E-I put Measuri g Cable -- Red (PN 11411-R)
Alligator Clamp -- Black (PN 11412-B)
Alligator Clamp -- Red (PN 11412-R)
Power Cord (No PN)
QA-ES User and Service Manual (PN 14025)
3. If you ote physical damage, or if the u it fails to fu ctio ac-
cordi g to specificatio , i form the supplier immediately.
Whe METRON AS or the compa y’s represe tative, is i -
formed, measures will be take to either repair the u it or dis-
patch a replaceme t. The customer will ot have to wait for a
claim to be i vestigated by the supplier. The customer should
place a ew purchase order to e sure delivery.
4. Whe retur i g a i strume t to METRON AS, or the compa y
represe tative, fill out the address label, describe what is wro g
with the i strume t, a d provide the model a d serial umbers.
If possible, use the origi al packagi g material for retur ship-
pi g. Otherwise, repack the u it usi g:
a rei forced cardboard box, stro g e ough to carry the
weight of the u it.
at least 5 cm of shock-absorbi g material arou d the u it.
o abrasive dust-free material for the other parts.
Repack the u it i a ma er to e sure that it ca ot shift i the
box duri g shipme t.
METRON’s product warra ty is o page ii of this ma ual. The
warra ty does ot cover freight charges. C.O.D. will ot be ac-
cepted without authorizatio from METRON A.S or its repre-
se tative.
2.2 Setup
1. Equipme t co ectio is as show i the typical setup below
(for Power Distributio Test).
1

2. If you are usi g a oscilloscope, attach the BNC cable to the
Scope Output co ector, located o the fro t of the QA-ES.
3. If PRO-Soft QA-ES is bei g used, attach a RS-232 ( ull mo-
dem/data tra sfer co figured) cable to the 9-pi D-sub outlet
port located at the rear of the QA-ES. Do ot attach the pri ter
cable to the QA-ES. See below. However, if you are ot usi g
PRO-Soft QA-ES, a d are se di g directly to a pri ter for pri t-
outs, attach the pri ter cable to the 25-pi outlet port.
2.3 PRO-Soft QA-ES
PRO-Soft QA-ES is a fro t-e d test automatio a d prese tatio
tool for METRON's ESU Performa ce A alyzer. It allows you to
co duct the same tests, but by remote co trol via a IBM-compati-
ble PC/XT with MS Wi dows (Versio 3.1 or later). Additio ally,
the program has features to e ha ce your QA-ES’s performa ce.
Each of the QA-ES tests ca be ru i depe de tly from PRO-Soft i
the “Ma ual” test mode. Results are show o the PC scree duri g
testi g, a d the user is prompted to set the tested equipme t accord-
i gly. At the co clusio of tests, the user may pri t a report, store
the test a d results o disk, or both. Combi atio s of tests ca be
created a d stored as “Test Seque ces.” The program mai tai s a li-
brary of these seque ces. I this way you ca store a d retrieve se-
CAUTION
The QA-ES uses a 3-wire
ower cord and lug for
the user's safety. Use this
ower cord in conjunction
with a ro erly grounded
electrical outlet to avoid
electrical shock.
2

que ces that are appropriate for each ESU bei g tested at your facil-
ity.
Seque ces ca the be used i depe de tly, or ca be attached to a
checklist, writte procedure, a d equipme t data i the form of a
test “Protocol.” The equipme t data ca be e tered ma ually i to
the protocol, or it may be retrieved by PRO-Soft from a database
program, or other equipme t files. Protocols ca be created easily
for each ESU i your i ve tory, a d stored for use. Test protocols
with results ca be pri ted, or stored o disk, a d the results of test-
i g ca be se t back to the equipme t database to close a work order
a d update the service history.
NOTE
PRO-Soft QA-ES has its
own user manual, which
contains all the information
concerning the rogram. If
you order a demonstration
version of the rogram you
also receive the manual.
