1. Introduction
This chapter describes the METRON QA-1290 Non-Invasive Blood
Pressure (NIBP) Analyzer’s features and specifications.
1.1 Features
METRON’s QA-1290 NIBP Analyzer is a precision instrument, de-
signed for use by trained service technicians, for verifying the per-
formance of all types of adult and neonate oscillometric NIBP moni-
tors.
It does this in two stages. The first stage is auto-calibration. QA-1290
calibrates both the cuff and tubing in order to verify the NIBP moni-
tor used. Then, the QA-1290 performs calibrated simulations under
all conditions.
The QA-1290 provides for dynamic performance testing using both
real and simulated blood pressure waveforms. Blood pressure wave-
forms include individual settings for systolic BP, diastolic BP, heart
rate, and the pulse volume/amplitude.
The QA-1290 also simulates calibrated artifact and arrhythmias in a
large variety of real-life conditions. It provides high/low pressure re-
lease verification and automated leak testing. It also generates user
selectable pressure levels to calibrate a variety of pressure monitors.
Highlights:
• High performance, compact design, simple to use
• Performs a complete test including cuff and tubing
• Large selection of adult and infant preset BP conditions
• Programmable customized patient conditions
• Simulation of real-life artifact and arrhythmia conditions such as:
Bradycardia, Tachycardia, Geriatric Patient, Obese Patient,
Strenuous and Mild Exercise, Weak Pulse, Premature Atrial
Contraction, Premature Ventricular Contraction, 2nd Degree
Heart Block, Atrial Fibrillation.
• Digital manometer with automatic or manual inflation of the cuff
pressure for Leak Test and Over Pressure Cut-off Test
• Updates and enhancements of internal firmware via the RS-232
1-1

Test results, shown in the QA-1290's digital display, can be printed
out directly, or transferred to a PC via the ansur QA-1290 test auto-
mation software. ansur lets you design test protocols, remotely con-
trol the QA-1290, and store the test results.

2. Installation
This chapter explains unpacking, receipt inspection, and setup.
2.1 Receipt, Inspection
and Return
1. Inspect the outer box for damage.
2. Carefully unpack all items from the box and check to see that you
have the following items:
• QA-1290 NIBP Analyzer (P.N. 17500)
• QA-1290 Tubing Kit (P.N. 17515)
• BP Cuff Mandrels – adult and neonate
• QA-1290 User & Service Manual (P.N. 17525)
3. If you note physical damage, or if the unit fails to function accord-
ing to specification, inform the supplier immediately. When
METRON or the company’s Sales Agent is informed, measures
will be taken to either repair the unit or dispatch a replacement.
The customer will not have to wait for a claim to be investigated
by the Sales Agent. The customer should place a new purchase or-
der to ensure delivery.
4. When returning an instrument to METRON, or the Sales Agent,
fill out the address label, describe what is wrong with the instru-
ment, and provide the model and serial number. If possible, use the
original packaging material for return shipping. Otherwise, repack
the unit using:
• a reinforced cardboard box, strong enough to carry the
weight of the unit.
• at least 5 cm of shock-absorbing material around the unit.
• nonabrasive dust-free material for the other parts.
Repack the unit in a manner to ensure that it cannot shift in the
box during shipment.
METRON’s product warranty is on page ii of this manual. The
warranty does not cover freight charges. C.O.D. will not be ac-
cepted without authorization from METRON or its Sales Agent.

2.2 Setup
Equipment connection is as shown in the typical setup below. Attach
the printer cable to the 25-pin outlet port.
If ansur QA-1290 is being used, attach an RS-232C (null mo-
dem/data transfer configured) cable to the 9-pin D-sub outlet port lo-
cated at the rear of the QA-1290. Do not attach the printer cable to
the QA-1290. See below.
NOTE
Some RS-232C cables are
missing the connection between
the seventh and the eighth
wires in the cable. The cable
may still be called
NULL-modem, but it will not
work with the QA-1290. Refer to
the ansur QA-1290 Users
Manual for more information.
2.3 Connecting the Device
under Test
The connection of a mono-tube NIBP Analyzer and cuff is as shown
below. Tubing from the NIBP Analyzer is connected to the luer lock
on the Inlet Port, while the Cuff’s tubing is connected to the luer lock
on the Cuff Port.
2-2

The connection of a NIBP Analyzer and cuff that use two tubes is as
shown below. Tubing from the NIBP Analyzer is connected to the
luer lock on the Inlet Port, while the Cuff’s tubing is connected to the
luer lock on the Cuff Port.
With its Tubing Kit (P.N. 17515) METRON offers a number of pres-
sure connector adapters. The adapters connect to the QA-1290 Pres-
sure Port via a quick-disconnect, airtight, O-ring pressure fitting. See
Appendix A, Tubing Kit Components.
Note: The QA-1290 has an internal fixed volume that is used to simu-
late the cuff once the simulation begins . By connecting the inlet port
and cuff port of the QA-1290 together and then to the monitor under
test testing can be done without an external cuff connected.
2-3

2.4 Ansur plug in QA-1290
Ansur for the QA-1290 is a front-end test automation and presenta-
tion tool for METRON's QA-1290 NIBP Analyzer. It allows you to
conduct the same tests, but by remote control via an IBM-compatible
PC/XT with MS Windows (Version 98 or later). Additionally, the
program has additional features to automate and enhance your testing
program.
Each of the QA-1290 tests can be run independently from Ansur.
Results are shown on the PC screen during testing, and the user is
prompted to set the tested equipment accordingly. At the conclusion
of tests, the user may print a report, store the test and results on disk,
or both. Combinations of tests can be created and stored as “Test
Templates.” The program maintains a library of these sequences. In
this way you can store and retrieve sequences that are appropriate for
each kind of equipment being tested at your facility.
NOTE
Ansur QA-1290 has its own
user manual which contains all
the information concerning the
program. If you order a demon-
stration version of the program
you also receive the manual.
Sequences can then be used independently, or can be attached to a
checklist, written procedure, and equipment data in the form of a test
“Protocol.” The equipment data can be entered manually into the pro-
tocol, or it may be retrieved by Ansur from equipment database man-
agement programs, such as METRON’s QA-MAP, WOSYST or
other equipment files. Protocols can be created easily for each item of
equipment in your inventory, and stored for use. Test protocols with
results can be printed, or stored on disk, and the results of testing can
be sent back to the equipment database to close a work order and up-
date the service history.

3.2 QA-1290’s Controls
QA-1290’s display, alphanumeric data entry keys, control keys and
programmable function keys provide flexibility and control in testing.
Operating them is very similar to operating a personal computer.
There are four text lines to each screen. The top three lines are used
for operator settings, system messages, and test status and results.
They are controlled by the F5, F6 and F7 keys, located to the right of
the display. Note, however, that these keys are active only when you
see the leading arrows (“. . . . . .>”) pointing to them. (See above)
The screen’s bottom line is a menu bar, controlled by function keys
F1 through F4 directly below the display. The menu is used for sys-
tem functions, such as PRINT or INFLATE, and for inter-screen
navigation, such as MORE and GO BACK.
