For Powerchairs, the multimeter is one of the
most useful tools in the toolbox (figure .3.1). It
can be used to check wires, shorts, voltages,
resistance, and all manner of electrical circuits.
This tutorial is designed to help clarify the sym-
bols and socket options. This Section is meant to
be a General tutorial and may not apply to all of
the specific options on the meter in use. Please
consult your user's manual, to avoid errant read-
ings.
1. The Common Port. (figure .3.3)
Generally, the black probe plugs in here
(negative) and as the name suggests, it’s the
common element to all of the testing circuits.
Think of it as the ground rail.
2. Voltage, Resistance and Continuity port.
This is a commonly used option. Connect
the red (positive) probe to this port when
finding voltage readings, resistance readings
or when checking wire continuity. This is ex-
plained in more detail later in the tutorial.
3. Current up to 400mA.
This port is used for “counting electrons” in
a circuit, and thus their rate of flow (current
being the flow of electrons). You’ll notice that
this side is “fused”, so that you don’t end up
melting the meter’s circuits.
4. Current up to 10A.
Same as above, except it can take more cur-
rent, as the name suggests.
The Probes
The Ports
The Multimeter
Section 1
Probes are found on various multimeters (figure
3.2). The Probes connect the meter to the circuit.
Simply touch them to the directed area with the
Mulitmeter on the correct settings, and read the
display. Carefully follow instructions for place-
ment of the probes to avoid errant reads.

Section 1
AC - ALTERNATING CURRENT - Use this when you want to test
something that has AC current running through it. Typically you'd
want to test the voltage of an inverter (for cold cathodes or neons),
or a similar device
DC- DIRECT CURRENT. This is the type of electrical power
produced by a battery. With a battery connector, the black wire(s)
should be connected to the negative(-) terminal of the battery
and should be considered the common ground. The red wire(s)
should be connected to the positive(+) terminal of the battery and
is considered the “hot” lead.
Voltage- This means Voltage or Potential Difference. It will
measure the potential difference between the two probes. To
measure voltage, connect the positive probe to a port that is
marked “V” or Voltage. Note: “mV” means milli-volts = .001 Volt
Current- Since current is measured in Amps and the readout
value is in amps, the symbol "A" is used. On this setting the unit
measures current that is flowing through the part of the circuit
between the two probes (the meter itself). Typically, you need to
plug the positive terminal into a port marked “A” or Current. You
need to put the meter “In Series” in the circuit to use this feature
correctly.
Resistance- This symbol represents Resistance and is measured
in Ohms. You can use this setting to measure the resistance
between two points; for example across a piece of wire or a
resistor (to check its value). If you don’t have a continuity check,
then this can be used to check for shorts. Any value below 0.05
Ohms constitutes a short, meaning that whatever the probes are
attached to is connected electrically.
Continuity- A commonly used function. By putting a current
through the two terminals (the same as the Ohm-meter function)
it can be determined if the resulting value is within the “contact”
range, this is signified with a beep. Found on some multimeters,
it allows a check for shorts without taking your eyes off your work.
Other meters signify this with a small flashing light.

Health and Safety
While working on powered mobility products, it is essential to observe
good working practices. Below are a series of safety guidelines and
recommendations. Please note that these precautions are intended to serve
only as a guide, not to supersede or replace any safety statute, NHS or other
safety regulations.
General
• Always wear suitable protective clothing when handling batteries.
• Always wear suitable eye protection when drilling or inspecting.
• When safe to do so, wear protective gloves when handling the running
gear or batteries, as these parts are exposed to paths, parks etc.
• If the drive wheels have to be raised off the floor, always use a pair
of axle stands to secure the vehicle.
• Use extra caution when working with batteries.
• Always make sure that the batteries are disconnected from the device
before commencing work.
• Always check that the battery charger is disconnected from the device
/batteries before commencing work.
• Do not smoke while working on this device.
• Keep batteries away from all sources of ignition.
• Do not place objects on top of the batteries.
• Always keep someone close to your work area so that they may come
to your assistance if needed.
• Always wear personal protection when handling batteries, including,
eye/face protection and gloves.
• Make sure there is easy access to soap and water in case of acid
spills.
• Avoid touching eyes or unprotected parts of the body while working on
batteries.
• Remember that non-sealed batteries can contaminate any packaging,
housing, or boxes they may have been transported in so handle all
packaging with care, especially during disposal.
• If battery acid should come into contact with bare skin or clothing, be
sure to wash contacted area immediately, using plenty of soap and
water. If battery acid enters the eyes, flush with running cold water for
as long as possible while medical help is being sought.
• When the tops of batteries are exposed, take extra care when working
on or around the terminals.
• Do not allow metal tools to drop on to or touch the exposed terminals
of the batteries or other exposed connections, as this could cause a
short circuit, which may result in an explosion.
Battery Safety
Section 1
Health and Safety

QM-7 SERIES SERVICE MANUAL
PAGE 1.4 JANUARY 2012 SUNRISE MEDICAL
If mishandled batteries can be dangerous and hazardous.
• All mobility batteries, whether wet type or gel/sealed type, contain
lead and sulfuric acid. Both of these materials are toxic and in the
case of sulfuric acid, highly corrosive. Additionally, when batteries are
charged, they produce hydrogen gas which is “highly” flammable and
can cause explosion. This is why proper handling is mandatory at all
times.
• Battery explosion - This is frequently the result of too low an acid/
electrolyte level in the battery, which allows high concentrations of
hydrogen to build up. This is possible with all batteries if improper
charging or battery failure occurs, but not common in gel/sealed
batteries.
• < KEEP SPARKS AND FLAMES AWAY FROM BATTERIES >
• Burns - dropping a wrench or screwdriver across battery terminals
results in sparks, and intense heat. Improper assembly of battery
boxes or battery box wiring may short the battery through the wiring
and produce a possible electrical fire.
• Electronic damage - batteries that are improperly wired can short out
electronic chair components resulting in expensive repairs.
• Pollution - improper disposal of batteries could damage the
environment. All batteries should be disposed of through a reliable
battery recycler.

• Remove personal items of jewelry, such as rings, watches, chains
etc. before working on batteries. Such items could cause short
circuits resulting in serious burns.
• Batteries are constructed of heavy materials. Therefore moving
batteries requires appropriate lifting techniques. Safety footwear
should also be worn. In addition, disposal of old batteries requires
compliance to state laws. Contact your local authority for their
recommendations.
• Remember battery chargers are connected to household current.
• Always observe all guidelines and laws relating to electrical
equipment.
• Never operate the battery charger in wet or damp conditions.
• If you think that the charger has been exposed to water or excessive
dampness, do not use it. Return the unit to the dealer/supplier for
inspection/replacement.
• If you think the battery charger is defective or is visibly damaged,
return the unit to the dealer/supplier for inspection.
• EMI means electromagnetic (EM) interference (I). EMI comes from
radio wave sources, such as radio transmitters and transceivers. A
“transceiver” is a device that both sends and receives radio wave
signals.)
• There are a number of sources of intense EMI in our daily
environment. Some of these are obvious and easy to avoid. Others
are not, and the user may not be able to avoid them.
• Powered wheelchairs, although tested in accordance with EMC
guidelines, may be susceptible to electromagnetic interference (EMI)
emitted from sources such as, radio stations, TV stations, amateur
radio (HAM) transmitters, two-way radios, and cellular phones.
• EMI can also be produced by conducted sources or electro-static
discharge (ESD).
What effect can EMI have?
1. EMI can, without warning, can cause a power chair to:
• Release its electronic brakes
• Move by itself
• Move in unintended directions.
If any of these occur, severe injury could result.
2. EMI can damage the control system of a power chair, resulting in a
safety hazard and/or costly repairs.

1. Hand-Held Transceivers: Antenna is usually mounted directly on the unit.
These include:
• Citizens band (CB) radios
• “Walkie-talkies”
• Security, fire and police radios
• Cellular phones
• Lap top computers with phone or fax
• Other personal communication devices
Note - These devices can transmit signals while they are on, even if not in use.
The wheelchair should be switched off when not in use.
2. Medium-Range Mobile Transceivers: include two-way radios used in police
cars, fire engines, ambulances and taxi cabs. The antenna is usually mounted
on the outside of the vehicle.
3. Long-Range Transceivers: These include commercial radio and TV broadcast
antenna towers, amateur (HAM) radios, and alarm systems.
NOTE- The following are Not likely to cause EMI problems: Lap-top computers
(without phone or fax), cordless phones, TV sets or AM/FM radios, CD or tape
players.
EM energy rapidly becomes more intense as you get closer to the source. For
this reason, EMI from handheld devices is of special concern. A person using
one of these devices can bring high levels of EM energy very close to a power
chair without the user’s knowledge.
Immunity level
The level of EM is measured in volts per metre (V/m). Every power wheelchair
can resist EMI up to a certain level. This is called its “immunity level”. The higher
the immunity level, the less the risk of EMI. It is believed that a 20 V/m immunity
level will protect the power wheelchair user from the more common sources of
radio waves.
For the QM-710, the configuration tested and found to be immune to at least 20
V/m is: a right-handed mounted joystick system, 18” seat width, 18” seat depth,
dual-post height-adjustable armrests, fixed tapered legrests with one-piece solid
footplate and Gp 24 gel cell batteries.
The following dealer installed speciality input devices have an unknown effect on
the immunity level because they have not been tested with the Quickie control
systems:
• Breath Control (“Sip n Puff”)
• Tri-Switch Head Array
• Proximity Head Array
• Proportional Mini-Joystick/Chin Control
• Buddy Button
• Wafer Board

Sources of EMI

QM-7 SERIES SERVICE MANUAL PAGE 1.7
JANUARY 2012SUNRISE MEDICAL
To help prevent Electro Static Discharge (ESD) the following proper
handling techniques should be followed:
ESD:
• Do not place Printed Circuit Boards or their containers near
sources of strong electrical fields (such as above a CRT).
• To avoid the occurrence of static charge or discharge due to
friction, keep the Printed Circuit Boards separate from one an-
other and do not stack them directly on top of one another if not
protected by antistatic bags.
• Store each Printed Circuit Board in an antistatic bag with an
external cushioning bubble-wrap layer until assembled to
wheelchair. Antistatic bag must have metal content to protect
the printed circuit board. Gray bag protects from ESD, pink bag
or bubble wrap does not protect as well.
• Always wear an ESD preventive wrist or ankle strap when han-
dling electronic components. Connect one end of the strap to
an ESD jack or an unpainted metal component on the system
(such as a captive installation screw).
• Handle Printed Circuit Boards by the edges only; avoid touch-
ing the Printed Circuit Board and connector pins.
• Place any removed Printed Circuit Board on an antistatic sur-
face or in a static shielding bag.
• Avoid contact between the Printed Circuit Boards and clothing.
The wrist strap only protects the card from ESD voltages on the
body; ESD voltages on clothing can still cause damage.
• Make sure that the Printed Circuit Board power is off by dis-
connecting the seating harness prior to attaching or removing
printed circuit board.
Printed Circuit Board Flexing:
• The printed circuit board has surface-mount components that
may break when the board is flexed. To minimize the amount
of board flexing, observe the following precautions:
• Hold the printed circuit board only by the edges.
• Do not place the printed circuit board on a hard surface.
• Tighten board mounting screws only hand tight (torque12.4
in lbs/1.4Nm) in a cross pattern to reduce stress on mounting
holes and PCB board material.

• Batteries function as a power wheelchair’s
fuel tank. The larger the group size, the
farther the wheelchair will go.
• Use the size specified by the wheelchair
manufacturer. Never use undersized
batteries
• This chair uses either 22NF, or GRP 24
Batteries. Flat-top batteries help lower the
seat to floor height.
• Deep-cycle batteries used in wheelchairs
are designed to be discharged and
recharged on a regular basis.
• Starting or automotive type batteries use a
rapid burst of power to start an engine and
are quickly recharged by an alternator or
generator. They are rated by cold cranking
amps, a measure that has no relevance to
wheelchair application.
• Marine and RV batteries frequently are
not deep-cycle as they are often used for
starting engines.
• Only use Deep-Cycle sealed type
batteries in a wheelchair.
