MDtest (100-140 V) - User’s Manual 1 Introduction

1 Introduction

1.1 Safety

WARNING

Read this User’s Manual carefully and completely and follow

all instructions contained therein. If not, the use of the in-

strument may be dangerous for the operator, devices under

test or for the instrument!

If there is reason to believe that safe operation has become impossible,

put the instrument out of operation and secure it against any unin-

tended operation. Safe operation must be presumed to be no longer

possible, if:

•The instrument does not operate properly any longer.

•The instrument, cables, connectors, plugs or accessories exhibits

visible damages.

•The instrument was stored in unfavourable conditions for a long

period.

•The instrument was exposed to extraordinary stress caused by

transport.

WARNING

•Make sure that the instrument, measuring cables and all other

accessories are in ﬂawless condition, e.g. no damaged insulation,

no broken cables or plugs etc.

•Make sure that the AC outlet is easily accessible. If some trou-

ble or malfunction occurs, immediately disconnect the MDtest

adaptor from the outlet.

•If the equipment is used in a manner not speciﬁed by the manu-

facturer, the device’s protection may be compromised.

•The instrument may only be powered from a 100÷140 V / 50 or

60 Hz grounded mains outlet, which is protected with a fuse or

circuit breaker with a maximum rating of 16 A.

•Voltage 127 V / 50/60 Hz will be used in this manual hereinafter.

•In order to check the proper PE connection to a mains outlet,

MDtest generates a continuous current of ca. 1.5 mA / 50 or

60 Hz to the PE conductor. This test current can activate the

insulation monitoring device in IT systems.

•Only a trained, skilled person, who is familiar with hazardous

voltage operations, can handle the MDtest. Unexpected haz-

ardous voltages can occur on devices under test (dangerously

charged capacitors, etc.).

MDtest (100-140 V) - User’s Manual 1 Introduction

WARNING

•It is necessary to respect all safety regulations applicable to the

particular measurement.

•Test Socket 1of the MDtest must not be used for continuously

powering the appliance. It is intended for test purposes only;

max. test duration is 25 min @ ≤12 A and 60 s @ 12÷16 A.

•The functional test may only be performed after the DUT has

successfully passed the safety test.

•Dangerous voltage or mains voltage may be present on Test

Socket 1during some tests.

•Devices under test which are connected to Test Socket 1of the

MDtest can be powered by mains voltage during some tests. The

appliance can thus be activated.

•The PE terminal is connected to the PE terminal of Test Socket

1. When using the MDtest, do not connect any voltage to the

terminal PE. If connected, there is a danger of electric shock or

damage to the MDtest.

•Use only standard or optional accessories supplied with the

MDtest by your distributor.

The ﬁgures in this manual are only illustrative and may vary slightly

from the actual state or the version on your instrument.

1.2 Performance MDtest

The MDtest is a professional, compact, portable analyzer, designed to verify the

electrical safety of medical devices. The MDtest has an extraordinary wide scope

of use thanks to a lot of optional accessories, which enable testing practically any

portable or hard-wired, one-phase or three-phase medical device.

MDtest (100-140 V) - User’s Manual 2 Description of the instrument

2 Description of the instrument

2.1 General description

The MDtest instrument is designed to verify the safety of electrical appliances and

medical devices in general. All AC measurements are measured by the method

TRMS (true rms), and for some measurements the DC component value can be

displayed. Measured circuits meet the requirements of EN 60601 and EN 62353

(requirements for measuring circuits), including the required input characteristics.

The MDtest performs the following tests:

•Earth bond test >1 A AC

•Insulation resistance test 250 V DC

•Alternative (substitute) equipment and applied part leakage current

•Direct equipment and applied part leakage current

•Diﬀerential leakage current

•Ground (Earth) leakage current

•Chassis (Enclosure) leakage current

•Lead to Ground (Patient) leakage current

•Lead isolation (Mains on applied parts leakage current)

•PE current during operation and diﬀerential leakage current

•Apparent power, mains voltage and current consumption

With additional equipment can be measured:

•measurement of PE current during operation and diﬀerential leakage current

of three-phase portable appliance by means of optional adapters

•measurement of apparent power and current consumption by means of current

clamp

The MDtest has furthermore additional features, which improve the safety of both

the operator and the DUT. These include:

•check for dangerous contact voltage on the PE of power outlet (before the

start of the measurement)

•check if the PE of the power outlet is grounded (before the start of the mea-

surement)

•automatic check for leakage current amplitude of the device under test

•check of the appliance’s current with automatic switch oﬀ the Test Socket 1:
