Introduction
The Multi-Pro 2000 (PN: 560) is a full featured, compact
portable analyzer designed for the testing of the
electrical safety of medical devices. The analyzer tests to
US standards (ANSI/AAMI ES1, NFPA 99) or international
standards IEC60601-1 by user selectable patient loads.
It is compact, lightweight and user friendly unlike any
other safety analyzer in the market. The Analyzer is a
measurement device as well as a waveform simulator.
The Analyzer is capable of saving over 5000 test records
and can be uploaded to a PC for printing and record
keeping using the software shipped with the unit.
Optional stand alone “Equipment Maintenance
Software” is also available for the PC s.
The Analyzer is designed to be used for the quick and
easy measurement of the following functions.
•Line Voltage.
•Equipment current
•Polarity Check of the inlet AC power.
•Chassis (Enclosure) Leakage.

Measurements
Earth Leakage:
Earth leakage is compliant to IEC 60601 and ANS/AAMI
ES1 standard. The default compliant standard is set to
AAMI ES1. The Compliant standard can be changed by
pressing F1 to toggle between (AAMI “ES1” or “IEC”
60601). This will be saved to the memory until it is
changed again.
There are four Leakage measurement options.
•Normal Polarity
•Reverse Polarity
•Open Neutral
•OFF. Select the desired polarity.
The Earth leakage measurement is through the internal
ground conductor and the external test lead is not
required. To measure the current flowing in the
protective Earth circuit, press the key marked “Case
Leakage”. The display will indicate “CASE LEAKAGE” and
“Select Polarity” and “ES1” /IEC (AAMI ES1) or “IEC”
60601) selection.
Select the desire polarity and press “READ”. The display
will indicate the leakage as well as the polarity selected
as shown in Screen Shot 3. Press F1 (“SAVE”) to save the
results.

To save the result press F1 (“SAVE”). This will save the
test data in the memory under Device ID.
To measure leakage for open neutral conditions first
select first select “NORMAL POLARITY” followed by F6 to
open the neutral.
The auto-range feature of the MultiPro will select the
appropriate range automatically. For reading in excess of
100 micro amps, the decimal point will not be displayed.
The user can switch between Reverse and normal
Polarity at any time to verify readings or, to determine if
any service action performed on the device under test
affects the readings.

current is measured through the external test Lead.
To measure the case leakage/Enclosure leakage,
attach the external Kelvin cable to the case
(conductive surface) of the (DUT) device under test.
Select the desired polarity and press “READ”.
The display will indicate the leakage as shown in the
Screen Shot 4. Press F1 (“SAVE”) to save the results.
Case leakage measurements can be made for
various line conditions, power on, off, normal or
reverse polarity, closed or open ground, Closed or
open neutral.

External Leakage: Point to Point Measurement
It is also referred to as point to point Leakage.
This function can be used to measure Leakage
current flowing from any conductive surface of
the DUT and Earth ground.
From the “MAIN MENU” select “XTR” (F3 Key).
“EXTERNAL LEKAGE” Menu will be displayed with
the prompt to connect the Input Cable (Screen Shot
4). The external input Jacks are on the left panel
marked “INPUT”. To measure the leakage between
