Warranty

Netech warrants the MiniSim 1000 against defects in materials and workmanship for
one year from the date of original purchase. The standard warranty is extended for a
second year if the instrument is returned to Netech for its recommended yearly
recalibration.

During the warranty period, we will repair or, at our option, replace at no charge a
product that proves to be defective, provided you return the product shipping prepaid to
Netech Corporation. Only serialized products are covered under this warranty.

This warranty does not apply if the product has been damaged by accident or misuse or
as the result of service or modification by other than Netech Corporation, or if its serial
number is defaced or removed.

Netech reserves the right to discontinue the MiniSim 1000 at any time, and change its
specifications, price, or design without notice and without incurring any obligation.
Netech guarantees availability of service parts for 5 years after the manufacture of the
unit is discontinued.

The warranty is void if you elect to have the unit serviced and / or calibrated by
someone other than Netech Corporation.

The warranty covering your product becomes void when the tamper-resistant Quality
Seal is removed or broken without proper factory authorization.

We strongly recommend, therefore, that you send your instrument to Netech

Corporation for factory service and calibration, especially during the original warranty
period.

The purchaser assumes all liability for any damages or bodily injury, which may result
from the use or misuse of the unit by the purchaser, his employees, agents, or
customers.
In no event shall Netech Corporation be liable for consequential damages

General Overview
Introduction

The MiniSim 1000 Multi-Parameter Patient Simulator is an advanced microcontroller

based instrument. It is designed to simulate patient signals of ECG, arrhythmia, invasive
blood pressure, respiration, and temperature. The device also simulates square, sine,
triangle, and pulse performance waveforms.

The easy to operate MiniSim 1000 is menu driven via eight tactile feel soft keys. All
functions are displayed on a two-line sixteen-character LCD display.

The small hand held instrument is powered by one 9 Volt batteries or an optional AC
adapter. The MiniSim 1000 is CE marked and shipped with a Certificate of Calibration
traceable to the NIST.

The MiniSim 1000 is a rugged instrument that performs its simulations quickly,
accurately, and with ease.

to its steady mode.

RWD: R Wave Detection. R waves are generated with three varying parameters of
amplitude, width, and rate. The three parameter values are displayed on the LCD while
generated. Each test waveform is displayed for 20 seconds.

TalT: Tall T Wave Rejection. QRS and T waves are generated with the following
values:

QRS: Rate 80 BPM

Amplitude 1 mV
Width 100 ms
T Wave Duration 180 ms
QT Interval 350 ms
T Wave Amplitude 0.0, 0.2, 0.4, 0.6, 0.8, 1.0, and 1.2 mV .

In the automatic test sequence the T Wave Amplitude steps through the changes at one
minute intervals. The display indicates the T Wave Amplitude and the QRS Rate.

As the T wave amplitude increases, the first value at which the patient monitor counts
the T wave at 80 ± 8 BPM should be noted. This value should match the patient
monitor manufacturer’s specification.

PPR: Pacemaker Pulse Rejection. The test sequence cycles through normal paced
rhythm (AP), ineffective pacing (Asynchronous Pacing ASP), and pacemaker pulses
alone (PCR).

For normal pacing (AP),QRS and pacer waves are generated with the following values:

QRS: Amplitude 1 mV
Width 100 ms
T wave: Amplitude 0.2 mV
Duration 180 ms
Q-T Interval 350 ms
R-R Interval 1 Sec
Pacer: Amplitude 2 mV, -2 mV
Width 2 ms, 0.1 ms

For ineffective pacing (ASP), the values of the QRS and pacer waves are the same as
normal pacing except for the QRS rate that becomes 30 BPM and the pacer rate that
becomes 80 BPM.

During the ASP and AP test sequences the display will show the pacer amplitude, the
pacer width, and the QRS rate.

For pacemaker pulses alone (PCR) the values generated are:

Pacer: Rate 60 BPM
Width 2.0 ms, 0.1 ms
Amplitude 2 mV, -2 mV

During the PCR test sequence the display will show the pacer amplitude, the pacer
width, and the QRS rate.
Each set of values in the test sequence is generated and displayed for 20 seconds.

TAC: Time to Alarm for Tachycardia. The TAC test is designed to measure the time it
takes for the patient monitor to alarm after the onset of ventricular tachycardia. The low
and high alarms on the patient monitor should be set at 60 BPM 100 BPM before
starting the test.

This auto test sequence generates a QRS wave form at the rate of 80 BPM alternating
with a ventricular tachycardia waveform with rates of 206 and 195 BPM and amplitudes
of 1.0, 0.5, 2.0, and 4.0 mV.

Each waveform is generated for 20 seconds and the display will show the amplitude
and the rate of the waveform being generated.

Maintenance and Storage

Calibration / Service

The mechanical assembly of MiniSim 1000 contains no parts that can be serviced by
the user. The unit should be returned to Netech Corporation for repair or calibration.
The alignment and adjustment parameters are critical to the robust and efficient
performance of the unit and can be performed only at the factory.
The unit is factory calibrated with NIST traceable standards and recommended to be
calibrated once a year.

Netech maintains a complete repair and recalibration service at a very low cost and fast
turnaround. Estimates for repair and recalibration are available upon request.
MiniSim 1000 contains NO USER SERVICEABLE PARTS and calibration/ service
should be performed only by Netech. Attempt to repair / service the unit outside
Netech voids the warranty.

Returning the MiniSim for Re-Calibration

Products returned to Netech for repair or recalibration requires a RMA (Return

Authorization Number) for speedy processing of the service required.

To obtain a RMA number follow the link http://www.Netechcorp.US and fill in the required
information, Email service@netechcorporation.com or call 800-547-6557 (US & Canada),
International 631-531-0100.

When shipping units to the factory enclose a copy of the RMA and the number should
be on used as the reference in the shipping label.

The shipment should be addressed to:-
