Multimeter Tutorial
The Multimeter
For Powerchairs, the multimeter is one of the
most useful tools in the toolbox (fi gure .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 symbols and socket options. This Section is meant to
be a General tutorial and may not apply to all of
the specifi c options on the meter in use. Please
consult your user's manual, to avoid errant readings.
The Probes
Probes are found on various multimeters (fi gure
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 placement of the probes to avoid errant reads.
Fig .3.1
The Ports
1. The Common Port. (fi gure .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
fi nding voltage readings, resistance readings
or when checking wire continuity. This is explained 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 fl ow (current
being the fl ow 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 current, as the name suggests.

Section 1
Multimeter Symbol Defi nition
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 fl owing 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 signifi ed 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 fl ashing light.

Health and Safety
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 fl oor, always use a pair
of axle stands to secure the vehicle.
Battery Safety
• 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, fl ush 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.

Section 1
Health and safety (cont.)
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” fl ammable 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 fi re.
• 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.

QM-7 SERIES SERVICE MANUAL
Section 1
Health and Safety (cont.)
• 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.
Battery Chargers
• 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 Warnings
• 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.
QM-7 SERIES SERVICE MANUAL
JANUARY 2012SUNRISE MEDICAL
PAGE 1.5
Section 1
Sources of EMI
1. Hand-Held Transceivers: Antenna is usually mounted directly on the unit.
These include:
• Citizens band (CB) radios
• “Walkie-talkies”
• Security, fi re 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, fi re 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 confi guration 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, fi xed 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

Cautions for circuit boards
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 fi elds (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 another 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 fl exed. To minimize the amount
of board fl exing, 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 installed incorrectly can blow the
fuse for this system. Pay careful attention
to install the battery harness across both
batteries instead of to each of the batteries
individually. See Section 7 for correct
Battery Removal and/or Installation
Section 1
Battery Types
IT IS THE RESPONSIBILITY OF THE INSTALLER TO KNOW WHAT KIND OF BATTERIES TO
INSTALL IN A CUSTOMER’S WHEELCHAIR!
• 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.
Battery Size
• Batteries function as a power wheelchair’s
fuel tank. The larger the group size, the
farther the wheelchair will go.
• Use the size specifi ed 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 fl oor height.
Battery Installation

VR2 Troubleshooting
No power: Battery Diagnostics
Note: For access to batteries, refer to beginning of Section 7 (Battery Access/ removal)
Battery Servicing and Replacement
Batteries should last an average of 1 to 1.5 years.
Listed below are some Factors that may effect battery performance:
• Maintenance - Poor maintenance.
• Charging - Improper charging shortens battery life.
• Chair Components - Malfunctioning electronics, bad motors, electric brakes, and
corroded wiring are also capable of degrading the battery performance.
A routine test of deep-cycle wheelchair batteries should follow these guidelines:
1. Never replace just one battery at a time. This will create an imbalance when charging and
ultimately damage both batteries.
2. Check batteries for a voltage difference. A voltage difference of more than .4 volts D.C. is a
good indicator of a bad battery.
3. Voltage test - A dead battery cannot be effectively tested, yet many people mistakenly try to do
just that. Any battery that reads 11.0 volts or less is technically dead.
To perform any testing, especially a load test:
A. Batteries must be charged
B. The top charge must be taken from fully charged batteries if charge rate has just fi nished.
Battery Tests
• Load Test - This test can only be done on fully charged batteries and can only diagnose one
type of problem, (an internal short.)
• Capacity/Discharge T est - This is the only accurate way to test a deep-cycle battery for adequate
running time. The problem with this test is that it is time consuming.
• Current / Voltage check with a regular interval check - Another way of truly knowing how much
time your battery will last, but it is also time consuming.
Note: The voltmeters on load testers are not accurate enough to establish a state of charge.

Section 3
Battery Connection Test
1. Check that the female VR2 Bus plug on
the chair has voltage. Set the meter to DC volts
and measure pins 4 (using the red lead of the
meter) and 1 (using the black lead of the meter)
as shown in (fig 3.2.1)
2. If the voltage meter reads full voltage, then
replace the joystick module
If the voltage meter reads zero voltage, measure
the corresponding pins on the VR2 controller as
shown in (fig 3.2.2).
If the voltage meter reads full voltage, then
replace the jumper cable. If the voltage meter
reads zero, then measure the Battery Connector
as shown in (fig 3.2.3). If the voltage meter reads
full voltage, replace the controller, or proceed to
the next step.
Fig 3.2.1
Fig 3.2.2
Fig 3.2.3
Note: For access to batteries, refer to beginning of Section 7 (Battery Access/ removal)
Check Battery Wire Harness
1. Check that the battery wire harness has the
correct polarity. Set the meter to dc volts and
measure the connector with the red lead on the
positive terminal, and the black lead on the negative terminal as shown in (figure 3.2.4). If the
voltage is absent Replace the Main Battery wire
Harness. If the polarity is reversed correct battery wiring.

The Maximum Speed Indicator Ripples
How to Lock or Unlock the Wheelchair
Maximum Speed Indicator Ripples. This Indicates that the wheelchair is locked. To unlock the
wheelchair, deflect the joystick forwards until the control system chirps. Then deflect the joystick in
reverse until the control system chirps. Release the joystick, there will be a long beep. The wheelchair
is now unlocked. To lock the wheelchair, while the control system is switched on, depress and hold
the on/off button. After 1 second, the control system will chirp. Now release the on/off button, deflect
the joystick forwards until the control system chirps, and deflect the joystick in reverse until the control
system chirps. Release the joystick, there will be a long beep. The wheelchair is now locked.
The Maximum Speed Indicator Flashes
This indicates that the chair is charging . The chair will be ready to drive as soon as the charger is
unplugged.
Battery Gauge is Steady
This indicates that all is well.
Battery Gauge Flashes Slowly
The control system is functioning correctly, but you should charge the battery as soon as possible. At
22 V, the red light starts to blink. Each bar represents a .5V value. The controller requires 18V to start
and a minimum of 16V to work once started
Battery Gauge Steps Up.
Indicates the wheelchair batteries are being charged with the offboard charger. You will not be able
to drive the wheelchair until the charger is disconnected and you have reset the control system by
switching off the power and then powering up again.
Battery Gauge Blinks Every 2.5 Seconds
The control system has "gone to sleep" because the wheelchair has not been driven for a period of
time. The time period depends on the programming of the system. To re-start, reset the system by
switching off the power and then powering up again.
Battery Gauge Flashes Rapidly
Make sure the Joystick is completely released (Joystick should be centered and/or nothing is pushing
the gimbale out of center). The control system safety circuits have been activated and the control
system has been prevented from moving the wheelchair. This indicates a system trip, i.e. the VR2
has detected a problem somewhere in the wheelchair's electrical system. Please refer to this Section
(VR2 Controller Diagnostics).

Six Bars - Charger Connected
The onboard batteries are being charged with the off-board charger. You will not be able to drive the
wheelchar until the charger is disconnected. You will have to reset the control system by switching
off the power and then powering up again. The On-Board charger has no indication that the chair
is charging, and the chair will not move until complete. If the condition still exists after the charger
has been diconnected, and the chair has been switched off and then powered up again, the Joystick
module may be defective.
Seven Bars - Possible Joystick Trip
A joystick trip is indicated. Make sure that the joystick is in the center position before switching on the
control system. Check that the batteries are fully charged and in good condition, examine the joystick
for damage. This fault can also be caused by a joystick that fails to center itself due to being dirty,
bent or broken. If this is the case, replace the joystick module.
Note: If replacing the joystick does not resolve the issue, replace the cable connecting the joystick to
the controller.
Seven Bars + Speed Profile Indicator error
Inspect the wiring between joystick module and controller. Replace a jumper or joystick module that
has damaged wiring. If the problem persists replace the controller.
Eight Bars - Possible Control System Trip
Controller Fault - A control system trip is indicated. Make sure that all connections are secure. Check
that the batteries are fully charged and in good condition, and check all joystick connections and
cables. If this does not correct the problem,disconnect the power to the controller for 2 minutes, replug
in to reboot the module. If the condition still exits, then replace the controller.

Power Chair Will Not Drive Full Speed
An external micro-switch is mounted next to the actuator in the rear of the lift system. This microswitch is closed when the tilt is lowered. The closing of this micro-switch sends a signal to the control
module through the 6-pin connector located on the back of the tilt. The presence of this signal informs
the control module that the tilt is less than 20 degrees and that maximum speed should be used. If
the tilt is more than 20 degrees, the switch opens and invokes “creep” speed. Creep speed is a
predetermined speed programmed at time of manufacture. Creep is indicated by a “turtle” on either
the hand control or Omni.

Chair Won't Drive in Creep Speed When Tilted
An external micro-switch is mounted next to the actuator in the rear of the lift system. This micro-switch
is closed when the tilt is lowered. When micro-switch is closed, it sends a signal from the control
module through the 6-pin connector. The presence of this signal informs the control module that the
tilt is less than 20 degrees and that maximum speed can be used. If the tilt is more than 20 degrees,
the switche opens and invokes “creep” speed. Creep speed is a predetermined speed programmed
at time of manufacture. Creep is indicated by a “turtle” on either the hand control or Omni.

Battery Testing
Note: The QM-710 power chair uses either (2) 22NF, or GRP 24 batteries connected in series.
The circuit is protected by a non-serviceable fusible link in each battery harness. Prior
to performing any test, the battery terminals should be clean and tight. For Access to the
Batteries, Refer to Section 7: Battery Access/Removal.
1. Check for initial battery voltage at the joystick
using the battery charger connector. Connect the
Multimeter to the two outside pins (fi gure 5.1.1).
Pin 1 is positive (+) and pin 2 is negative (-). Fully
charged batteries are typically 25.6 VDC for the
pair, or 12.8 VDC each. Discharged batteries are
24 VDC or less for the pair.
2. Load test the batteries using either a commercial
load tester or the following procedure.
fig. 5.1.1
Note: V oltage greater than 26 to 28 VDC indicates the batteries are either over-charged, or have
just been disconnected from the battery charger, and contain a surface charge. If the batteries
are not freshly charged and voltage is excessive, inspect battery charger.
Warning: Failure to disengage the gearbox in the next step can cause unexpected operation
of the power chair.
To use the power chair’s motors as a load tester,
complete the following steps:
a. Disengage the motor/gearbox so the motors
can run in freewheel (fi gure. 5.1.2).
b. Connect the Multimeter to the joystick and
record the voltage (fi gure. 5.1.3). If the voltage
fig. 5.1.2
indicates a surface charge, run the motors for
a few minutes to dissipate the surface charge.
Note: in this example, a small surface charge is
present.
c. After the voltage has stabilized, record the
voltage. Typical value for a fully charged pair of
batteries is 25.6 VDC (12.8 VDC each).

Section 5
d. Operate the power chair at high speed by
operating the joystick in a high-speed profi le. The
motors should put approximately a 5 to 10 amp
load on the batteries.
e. Continue to operate the motors for 60 seconds.
Record the readings and compare them to the
following:
i. During the fi rst 5 seconds, normal voltage
drop should be approximately .5 to .6 VDC.
ii. During the remaining portion of the 60
seconds, the voltage should stabilize, dropping
no more than an additional .1 to .2 VDC.
iii. At the end of the 60 seconds, release the
joystick.
f. At the end of a 5 minute rest, note the voltage
recorded on the Multimeter. Normal indication at
the end of a 5 minute rest is typically the starting
voltage, or no more than .1 VDC less.
fig. 5.2.1
Notes:
• A rapid drop of approximately 1.5 or more during the fi rst 5 seconds indicates a shorted cell
in one or both of the batteries. The battery terminals should be checked to ensure that they are
tight and clean, and then the test should be repeated. If the terminals are tight, the batteries
should be replaced. Refer to Battery Removal section of this manual.
• A slow drop of more than .8 volts during the fi rst few seconds indicates a weakened pair
of batteries. Evaluate the age of the batteries and the use they have received, and consider
replacing them.
• If the voltage does not return to .1 VDC of the starting voltage at the end of the 5 minute
test, evaluate the age of the batteries and the use they have received, and consider replacing
them.

3. The individual voltage of each battery may
also be checked using a Multimeter. Connect the
Multimeter to the battery connector (fi gure 5.3.1).
Note: Refer to Battery Removal (Section 7).
Compare the values to the following.
a. 12.8 VDC indicates a fully charged battery.
b. The battery readings should be similar. Newer
batteries typically read within .1 to .2 VDC.
c. 13 VDC or more indicates an overcharged
battery, or one that has a surface charge from
being recently removed from the charger. Verify
correct operation of the battery charger if the
batteries have not recently been removed from
charge.
d. 11.9 to 12 VDC indicates a discharged battery.
Recharge as necessary.
e. Less than 11.9 VDC indicates an excessively
discharged battery.
f. Values larger than 13 VDC indicate either an
overcharged battery or one that has just been
removed from charge, as in the example (fi gure
