The multimeter is one of the most useful tools in the
toolbox. It can be used to check wires, shorts, voltages,
resistance, all manner of electrical circuits. This tutorial
is designed to help clarify the symbols and socket options found on various multimeters.
The Probes
Probes connect the meter to the circuit. Simply touch
them to the connections you want to measure and read
the display. Obviously, this depends on how the meter
is set up, and what is being measured.
MULTIMETER
PROBES
The Ports
The Common Port. 1.
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.
Voltage, Resistance and Continuity port. 2.
This is commonly used option. Connect the red
(positive) probe to this port when using any voltage readings, resistance readings or when checking wire continuity (explained in more detail later
in the tutorial).
Current up to 300mA. 3.
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.
Current up to 10A. 4.
Same as above, except it can take more current,
as the name suggests.
This section describes the basic symbols used in a typical multimeter.
AC
This symbol means 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
This means 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.
INTRODUCTION
Voltage
This means Voltage or Potential Difference. This measures 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 Voltage
Current
Technically, this term is incorrect. It should be “I” but since current is
measured in Amps and the readout value is in amps, the symbol makes
sense. This measures the 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 means 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. Basically, what it does is put a current through
the two terminals (the same as the Ohm-meter function) and if the resulting
value is within the “contact” range, it will beep. This feature found on some
multimeters enables you to check for shorts without taking your eyes off your
work. Other meters may have a light that turns on when a short is found.
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 vehicle before •
commencing work.
Always check that the battery charger is disconnected from the vehicle / batteries •
before commencing work.
Do not smoke.•
Keep batteries away from all sources of ignition.•
Do not place objects on the battery tops.•
Always try to keep someone within earshot of 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.
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 correct procedures. 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.
INTRODUCTION
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 we 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, 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: The 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: These 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 in department stores.
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.
The confi guration tested and found to be immune to at least 20 V/m is: QuickieRhythm
and Groove power wheelchairs with 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 Delphi control system:
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 cush-•
ioning 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 handling 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 touching the Printed •
Circuit Board and connector pins.
Place any removed Printed Circuit Board on an antistatic surface 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 disconnecting the •
seating harness prior to attaching or removing printed circuit board.
INTRODUCTION
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.
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 handing 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.

Factors that affect battery performance:
Maintenance - Poor maintenance.•
Charging - Improper charging shortens battery life. •
Chair Components - Malfunctioning electronics, bad motors, electric brakes, •
and corroded wiring are just some of the factors that may affect battery life and
performance.
Battery Servicing and Replacement
Automobile batteries, which are used for starting, are tested with a load tester to
assure a high rate of energy production in a short burst.
The voltmeters on load testers are not accurate enough to establish a
state of charge.
Deep-cycle batteries produce energy more slowly and are designed to hold up to
constant discharging and recharging. Testing a deep-cycle wheelchair or scooter
battery requires different procedures than an automobile battery.
A routine for testing deep-cycle batteries should follow these guidelines:
Never replace just one battery at a time. This will create an imbalance when charging
and ultimately damage both batteries.
Check batteries for a voltage difference. A voltage difference of more than .4 volts D.C.
is a true indicator of a bad battery.
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.
Load Test• - This test can only be done on fully charged batteries and can
diagnose one type of problem, an internal short.
Capacity/ Discharge Test• - 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 is also time consuming.
Deep-cycle batteries 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.

which connect to the Positive for RED and the Negative for the BLACK with JUMPER (White) joining the
system. The system has a 100 amp non-removable
fuse built into the Cable and a removable 15 amp fuse
for Auxiliary Power.
Inspecting the Fuses
Remove caps on each of the two 15 amp fuses and
visually inspect. Insure there are no breaks in the fuse
material. If continuity is still in doubt, unplug fuse from
holder and check resistance across fuse blades. Zero
resistance indicates a usable fuse. Infi nite resistance
indicates a non-usable fuse.
The 100 amp fuse must be checked by measuring their
continuity. Zero resistance indicates a usable fuse.
Infi nite resistance indicates a non-usable fuse. The
100 amp fuse is not replaceable, the harness must be
replaced.
Use the wheelchair manufacturer’s automatic charger for all routine •
charging.
The best recharge point for deep cycle batteries is roughly at 50% •
discharge.
Never run batteries completely fl at [total discharge].•
Do not purchase automotive chargers. They are not designed to charge •
deep cycle batteries and will quickly ruin gel/sealed batteries.
Do not use chargers designed for wet battery charging with gel/sealed •
batteries; their charging voltages are different.

The Quickie Rhythm base has a special 4-bar
suspension system that pulls the front caster wheels
up over curbs, while simultaneously maintaining
independent suspension on the remaining four wheels.
The front caster housing pivots horizontally, •
which absorbs front impact. Then the tension
between the caster and the drive wheel literally
pull the caster up over the curb.

For Rhythm, each rear suspension element controls
the pitch damper mechanism on that side of the chair.
Timing of the initiation of the anti-pitch function on the
Rhythm can be accomplished by the following method.
Place the chair on a pedestal so that the drive •
wheels are suspended off of the riding or work
surface.
To allow a clearer indication of anti-pitch function, •
move to the front of the chair and remove the
6mm hardware that secures the anti-sway bar
end links to the motor mounts (Fig. 1.60).
Lift the rear caster so that the black rubber pad •
Adjusting the timing of the anti-pitch effect is •
accomplished by rotating the nut at the end of
the anti-pitch actuation cable at the anti-pitch
housing. The anti-pitch housing is located on
the stainless steel anti-pitch shaft inboard of
the drive motor. (Fig 1.63) (NOTE: The free
threads seen between the nut and the cable
rotary barrel indicate that this anti-pitch is fully
engaged.)
As seen, the barrel end of the cable has •
a hexagonal shape and while an adjustable
wrench could be set to fi t this portion of the
cable, a vise-grip type of pliers would be better
suited to this application.
Adjusting the nut clockwise will increase the •
amount of suspension travel prior to anti-pitch
damping engagement. Adjusting the nut counter
clockwise will reduce the amount of suspension
travel prior to anti-pitch engagement.
After evenly adjusting the timing of the anti-pitch •
on each side, reinstall the 6mm anti-sway bar
and attaching hardware, then set torque to 6
ft-lbs or 8.13 Newton-meter.
Remove the chair from the pedestal. The •
procedure is complete.
The Front (B) and Side shrouds (A) are held •
in place by reusable shroud fasteners (C & Fig
1.71).
To remove the fasteners, insert a fl at blade •
screw driver under the slot of the fastener
center piece and pry up. (Fig 1.72)
The Battery compartment Lid (D) is removed •
by lifting up on the web handle and then pulling
forward.
The Rear Shroud (E) is removed by pulling the •
top of the shroud back then lifting off.

No delay for Power-down. •
All Joysticks have a Horn which is programmable •
for volume levels.
The QC4 and QC5 Joysticks have a Minimum •
speed designated as a Turtle and a Maximum
speed designated as a Rabbit
To increment the 4 separate LED’s press the •
Rabbit and to decrement or decrease the speed
press the Turtle button.
The QC5 is the only Joystick that uses an •

Control Operation Description
The Motor Controller is a 70 amp control module for
QC and 100 amp for QR. When used on fl at terrain it
will draw approximately 10 amps (+/- 2). On a steep
incline or curb, it will draw up to 70 amps of current
to give the motors a power boost for 10 seconds. If
required, it will deliver 35 amp output for an additional
100 seconds. Most controls would either shutdown or
go into full current rollback after going for that length
of time. The QC Motor Control will continue to deliver
output at 25 amps.

Wiring:
Before making any connections to the Controller, disable the Wheelchair by disconnecting the Batteries •
and/or elevating the drive wheels.
All wiring should be as short as possible to minimize voltage loss at High Current.•
Use only Sunrise Medical approved wiring Harnesses to connect the Motor Controller.•
Wiring should be suitably restrained and fastened to the wheelchair to prevent snagging and to ensure that •
there is no strain on connectors.
The fi rst step in Troubleshooting any Power Wheelchair is to look at the chair and break it down into four simpler
groups.

Actuator Tests
Notes:
The seating actuators contain encoders that provide position information to the Motor Controller or QMAC. •
Counter Reset Switches (CRS) automatically provide re-home information to the Motor Controller or QMAC. •
The re-home function occurs when the actuator moves across the CRS.
Failure to operate the seating system far enough to operate the CRS over time may cause the controller •
to lose counts and to not return to programmed position. Encoder errors may also occur if the CRS is not
exercised periodically.
Encoder errors are often cause by “homing” errors. Re-Home the wheelchair anytime encoder errors are •
present.
Creep speed (profi le) will be active anytime the back angle is 15 degrees from vertical. This angle may be •
from recline, tilt, or a combination of the two.
Creep speed (profi le) is active anytime the seat elevator is active. Raising the seat approximately 1/8” will •
invoke creep speed.
Creep profi le is a percent of maximum wheelchair speed. It is adjustable using the HHP or PCSS. However, •
the speed can never exceed the maximum safe speed predetermined by Sunrise Medical.
Verify that the actuator travels to the count programmed in the chair. Refer to the following notes:6.
If using Quickie iQ, this value may be found under Programmed Parameters Access, Motor Control, •
then Actuator 1 or 2. (fi g 2.23.24)

Changing the Seating Size
Changing the seating size of the Perfect Fit Seating
System is accomplished by either adjusting the width,
depth, and/or the back height by relocating the growth
pans; or by replacing the growth pans with growth pans
of different sizes.
Both the seat back and the seat pan width adjust
independently. To adjust either the seat back or seat
pan:
Locate the hardware securing the wings to the •
center pan of the Perfect Fit Seating System.
Note: Each hole on the back or seat pan allow
½ inch increments.
Determine the correct adjustment needed. •
Example, if the seat back is 16” wide and the
desired width is 17”, than each wing should be
moved ½” (one hole) outward.
Remove the hardware using the correct size •
Allen wrench.
Reposition the wing and reinstall the mounting •
hardware.
Note: A new back cushion may be needed after width
adjustment.
Note: Each starting back height adjusts upward 3”. The

The Recline Portion of the Perfect Fit Seating System
uses dual keipers to operate the back. Each keiper is
powered by independent 24 VDC motors. A cogged
belt connects the motors to the keipers.
The keipers are similar to those used in the automobile
industry to recline seat backs. A hinged rod
connects the left keiper to the right keiper to ensure
synchronization.
An optical encoder is mounted on the left keiper
assembly to record the rotation of the keipers. The
control module decodes this signal and calculates the
back angle.
A conventional joystick, or other input device, sends
actuator commands over the CANBUS line to the
control module. If a QR-MAC is also incorporated, the
commands are routed to it as well. The control module
or QR-MAC sends operating voltage to a PC board
mounted on the seat back.
The PC board has several functions, including routing
the voltage from the controller module to the recline
actuators. The optical encoder sends its signal to
the PC board. The PC board routes this signal to
the control module where it is analyzed for correct
operation and position.
For recline, the PC board receives a signal from a
rocker switch that is mounted in the center of the back.
This switch (the Encoder Reset Switch) is operated
by a sliding link connected to a strut. Its purpose is to
synchronize the optical encoders with the back angle.
This signal is sent to the control module.
The tilt system contains an 18-degree micro switch that
informs the computer when the tilt is at 18-degrees.
The purpose is to reset the encoder circuit each time
the chair is tilted past 18-degrees. With the exception
of the legrest system, the other seating functions reset
during the operation by recording the actions of microswitches located within the actuators.
Two reed switches are mounted on the same bracket
that houses the Encoder Reset Switch. One reed
switch is the End of Travel (EOT) “Home” for the up
direction of the actuator, and the other reed switch
is the EOT for the “Back”, or down direction, of the
actuator. These signals are sent to the PC board
which interupts the actuator current when the seatback
reaches either end-of-travel.
SEATING SECTION
Encoder Reset Switch
Fig 3.49
The actuators are connected to the PC board. The
actuator drive voltage is provided by the control module
and routed through the PC board to the actuators.
Creep (speed reduction) and drive lockout are
controlled by the Delphi system. Twelve degrees of tilt,
40 degrees of recline, or any lift will cause the chair to
drive in creep speed.
Drive lockout will occur anytime two or more of the
functions (tilt, recline) are causing the chair to drive
in creep speed. Example, if the chair is tilted past 12
degrees and also reclined more than 40 degrees, the
chair will not drive.
