Introduction and Specifications
Introduction

Introduction
The DALE601/601E Electrical Safety Analyzer, hereafter referred to singly as
the Analyzer, is a simple, highly versatile, and portable instrument. The
Analyzer is used to evaluate the basic electrical safety of electrical systems,
medical devices, and physiological instrumentation, and a broad range of
external measurements, as listed under Key Features.
Its compact handheld size makes it an ideal addition to a toolbox, as well as
serving as a bench top instrument for the laboratory. The Analyzer does not
sacrifice functions or accuracy, and its low cost permits putting one on each
bench.
Simplicity
The Analyzer is simple to use, incorporating the following:
•
A single, labeled master function switch that leads the user through a
complete specific measurement procedure
•
A single range meter for each measurement that minimizes the chance of
erroneous readings
•
Heavy-duty switches that change polarity, open and close the neutral, and
select chassis or earth leakage current measurements
•
A single slide switch that gives the user a choice of AAMI or IEC test
load
•
Five universal EKG lead connectors that allow for any type of lead
connection
•
Green and amber lights that indicate five power line conditions
The Analyzer uses sophisticated electronics for true rms measurement of
current and voltage. Input impedance uses the manually selectable AAMI ES11993 or IEC601-1 test load to compensate for high frequency components in
the measurement. Resistance measurements are made with a four-wire Kelvin
bridge to eliminate errors resulting from cable length and connector resistance.

DALE601/601E
Operators Manual
Versatility
The Analyzer has an additional unique capability to make a broad range of
external measurements, including leakage current and/or voltage gradients and
the resistance between two points. Providing the voltage and measuring
function, the Analyzer can independently measure the isolation current of a
device. Thus, the Analyzer can evaluate the electrical system; system
installation; and, separately, the isolation of probes and transducers, in addition
to conventional leakage current measurement.
General Safety Considerations
The Analyzer should be inspected and its related documentation reviewed for
familiarization with safety markings and instructions before operation.

General Safety Considerations
1
Warnings and Cautions
A Warning identifies hazardous conditions and actions that could cause
bodily harm or death.
A Caution identifies conditions and actions that could damage the Analyzer,
the equipment under test, or cause permanent loss of data.
XW Warning
To avoid possible electrical shock or personal injury,
follow these guidelines:
•
Disconnect all patient connections before connecting
the device to be tested to the Analyzer. Continued
connection may jeopardize patient safety by possible
application of measurement currents.
•
Maintain care when making connections. Isolation test
uses 120 or 230 V ac applied to patient leads or to
external connections that are accessible to the tester.
Although the voltage is current limited to 1 mA is safe
for healthy intact skin contact, it can be felt and can
result in a startle reaction.
•
Ensure the mains installation current rating is
adequate for the DUT (device under test). If the DUT
requires 20 A, the Analyzer must be powered by a 20 A
service to avoid overloading the mains installation.
W Caution
To avoid possible damage to the Analyzer, follow these
guidelines:
•
Ensure that the DUT power requirements are within the
capabilities of the Analyzer, labeled as 15 A or 20 A at
120 V ac (depending on model purchased) and 10 A at
230 V ac. While the analyzers are equipped with
receptacles limiting access to devices of higher
ratings, the replacement cord set may have been
installed incorrectly.

DALE601/601E
Operators Manual
•
This device is sensitive to electromagnetic fields. If
interference is encountered in measurements,
reconfigure the test setup or contact the manufacturer.
•
Do not leave the DUT connected and drawing high load
current for extended periods. The Analyzer is not
designed for continuous measurements and may
overheat.
•
Always pause in the OFF (middle) position when
switching polarity from normal to reverse. Inductive
loads of the DUT may create high voltage transients
when trying to reverse the direction of current flow
instantaneously.

Preliminary Steps
The Analyzer measures electrical parameters, as described below. These
voltages and currents are a natural phenomenon, and their presence within
reasonable limits does not constitute a hazard. However, it is necessary to
measure their values to determine if there is a significant change from previous
measurements or from the device specifications.
Figure 2-1 is a block diagram of a typical line-operated instrument with patient
connections. Measured parameters are labeled, and the discussions that follow
are keyed to the labels in the diagram.

Preparing the Analyzer for Use
XW Warning
To avoid possible electrical shock or personal injury to the
patient, disconnect all patient connections to the device to
be tested before starting.
To prepare the Analyzer for use:
1.
2.
Place the Analyzer’s switches in the following initial positions:
FUNCTION switch
Mains Voltage
NEUTRAL switch
CLOSED
OUTLET switch
OFF (center)
Plug the Analyzer into a properly-rated outlet.
XW Warning
To avoid possible electrical shock or personal injury to the
patient, plug the Analyzer only into a grounded, “Hospital
Grade” power receptacle. Do not circumvent this
precaution for any reason.
The Analyzer is equipped with a hospital-grade power plug. Grounding

Measuring Earth Resistance
Earth Resistance (RG) (grounding resistance) is the resistance from the DUT
conductive "grounded" chassis to the grounding terminal on the receptacle into
which it is plugged. Maintaining a low resistance is important to protect the
chassis from becoming "hot" with current as a result of an internal fault. The
resulting voltage drop across the ground wire raises the potential of the chassis
with respect to the local ground, creating a potential hazard.
The ground wire in the power cable is responsible for most of the resistance,
which is proportional to the cable length. See Table 2-1 for typical values for a
10-foot cable. The resistance measurement also includes the junction
resistance in connecting the wire at both ends and the bulk resistance of the
chassis from the grounding point to the point of measurement.
Low resistance values are being measured between the clip on the black
chassis cable and the grounding pin receptacle of the Analyzer. Therefore, the
Analyzer uses a four wire Kelvin bridge to make the measurement, avoiding
errors caused by the contact resistance of the cable connectors and the length
of the test cable.

Operators Manual
Measuring Leakage Current
Leakage current is the flow of current through or over the surface of an
insulating material or insulator. Leakage current is caused by the proximity of
the hot wire or line potential components to the chassis. In Figure 2-1, this
relationship is represented by ZL, a combination of capacitance (CL) and
resistance (RL) components. For example, if a person comes in contact with an
operational device, leakage current flows from the contact point, through the
person’s body, and back to ground. Measurement of leakage current is required
on all mains power products.
Earth Leakage Current
Earth Leakage Current (IE) (internal chassis current) flows in the ground wire
of the power cable to return the chassis leakage current to true earth ground.
This current is not a hazard if the ground wire remains intact and the current
does not become excessive. This leakage can occur if a major fault results in
the ground wire sharing the load current with the neutral wire or in supplying
the total return. The measurement is made using the 1000 Ω AAMI load
placed directly in series with the ground wire. Open neutral usually represents
the worst case.
To measure earth leakage current:
Note
Earth leakage current flows normally in the ground wire of the
device. This test is applicable only to devices using three-wire
(grounded) power cords.

Enclosure (Chassis) Leakage Current
Enclosure Leakage Current (IC) flows between the accessible conductive
chassis or enclosure and earth ground, as measured through a 1000 Ω
impedance. Under the condition of an open ground, this current is the same as
the earth current. With ground intact, the current should be very low, reflecting
the mΩ impedance of the ground wire paralleling the 1000 Ω AAMI load.
Note
Differentiation is made between earth and chassis currents because
the wide use of insulated enclosures makes a conductive chassis
inaccessible. Under this condition, earth current represents total
leakage.
To measure enclosure leakage current:
1.
Connect the standard cable (supplied with unit) that has a black coil cord
cable with the clamp with black insulation to the CHASSIS connector on
the top panel of the Analyzer.

Patient Lead Leakage Current

pathways directly to the heart, but it has become standard for all devices
having any patient-applied parts.
This test simulates the condition of a patient with leads attached touching
ground such as an electric bed. If the patient connections are not isolated, this
current reflects the earth current when tested under the open ground condition,
as this is its only path back to true earth. For devices incorporating isolated
patient connections, this current is reduced by the patient isolating impedance
ZI, a combination of resistive and capacitive leakage.
Measurement is made to the lead selected by the lead selector switch, with the
other side of the AAMI load connected to system ground.

Measuring Patient Auxiliary Current
Patient Auxiliary Current (IA) (lead-to-lead current) flows from any patient
lead to any other patient lead and to all other leads connected together,

•
Bias current of the input amplifier
•
Reverse leakage current of input protection diodes
•
Lead-off sensing current
•
Impedance measurement current such as for respiration
The currents can be dc or ac or a combination of both. They are measured
using a true rms to provide the common base necessary for accurate readout
with a variety of common waveforms.
Measurement is made with a completely floating circuit to avoid extraneous
leakage currents to ground introducing errors. Measurement is made from the
selected lead to all other leads connected together, thus reducing the
permutations required to cover all possibilities.

Under normal conditions, the current is primarily input bias current,
measuring current or leadoff sensing current. The worst case condition is
measured from the individual lead to all other leads connected together.
The single lead carrying the most current is generally considered the
reference lead (RL) because it acts as the return for the other leads.
Therefore, the leads can be taken in groups of four with the common
reference lead (RL) and then summed.
Measuring MAP (Patient Lead Isolation) Current
MAP (Mains on Applied Parts) Current (II) (patient lead isolation current) is
that which would flow into the DUT if the patient were to come into contact
with full line voltage. An example is an electric patient bed that has become
ungrounded and has a short to the frame.
Measurement is made in each individual leads, but a common value is found
for all leads, as well as for the ALL position, as this is the measurement for the
isolation of the patient circuit. To assure proper reading, the test should be run
with ground intact. For additional safety, the current is applied to the patient
leads only when the ISO TEST switch is pressed.

For this test, the Analyzer provides a specially shielded line voltage secondary
on its power transformer that minimizes internal leakage currents from the
measuring circuit. This avoids the necessity of measuring the current and
subtracting it from all readings. The current is limited with a 120 KΩ resistor
for user protection.

A low impedance (1000 Ω) voltmeter as specified by the NFPA, with a
range to 1999 mV.
•
A 1000 µA ammeter to measure the leakage current between two devices
or between the DUT and a local ground reference. Range is to 1999 µA.

DALE601/601E
Operators Manual
Measurement is made with a 10 mA dc current and is highly resistant to ac
currents flowing between the measurement points as a result of chassis leakage
current from either or both devices. However, such leakage current may have a
dc component from rectification within the instrument. This dc current adds
and subtracts from the measurement current, resulting in some error that can be
corrected for by reversing the connections, remeasuring, and averaging the two
readings.
