OPERATING INSTRUCTIONS
Ammeter
Order no.:
84 20 52
This product complies with the applicable national and European specifications.
Intended Use
The ampere meter serves to display the charge or discharge current of the on-board battery on the inside of vehicles.
This product may only be operated if it is connected to a 12V DC car power supply with the negative terminal of the car
battery connected to the body. It may only be installed and operated in vehicles supplied with this kind of voltage. Never
connect the device to any other power supply.
Use is only permitted inside the car, not outside. Contact with moisture or dampness must be avoided at all times. The user
must make sure that the way the product is installed protects the product from humidity and wetness.
Any use other than that described above will damage this product and involves the risk of short circuits, fire, electric shock,
etc.
No part of this product may be modified or rebuilt.
The safety instructions must be observed at all times.
Safety and Hazard Notices
The guarantee/warranty will be void if damage is incurred resulting from non-compliance with
these operating instructions. We do not assume liability for any consequential damage.
We shall not accept liability for damage to property or personal injury caused by incorrect
handling or non-compliance with the safety instructions. In such cases the warranty/guarantee
is void.
An exclamation mark in a triangle points out important instructions in the operating manual.
Please read through the operating instructions completely before operating the device. They
contain important information for correct operation.
• Prior to commissioning, check the device for damage. If the device is damaged, do not put it into
operation.
• The unauthorized conversion and/or modification of the product is inadmissible because of safety
and approval reasons.
• The device may only be used with the 12V DC vehicle power supply (with the negative terminal of
the battery connected to the body of the vehicle). Never connect the device to any other power
supply.
• Make sure you use the device properly. Please also follow these operating instructions.
• Consult an expert when in doubt as to the operation, the safety or the connection of the device.
• Check the device and the connection leads for damages from time to time. An expert must repair
the product in case the device or the connection cables are damaged.
• Avoid heavy mechanical stress on the laminator and do not expose it to strong vibration or dripping
or spray water.
• Never pour out liquids above the device. You run the risk of causing a fire or a fatal electric shock. If
any liquid should nevertheless penetrate the device, immediately disconnect it from the power
supply network and contact a specialist.
• The device does not belong in the hands of children. Keep it away from children.
• Do not leave packaging material lying around carelessly. It may become a dangerous toy for
children.
• If you are not sure about the correct connection or if there are any questions that are not covered
by the operating instructions, do not hesitate to contact our technical support or another specialist.
• Observe the additional safety instructions in each individual section of these instructions.
Installation
The general safety instructions and regulations must be heeded by all means when performing
mounting works in, around and under the vehicle. Also observe the safety instructions of the
vehicle manufacturer!
Modifications to the vehicle which are made necessary through the installation of the device
must always be carried out in such a manner that neither the traffic safety nor the designed
stability of the car is impaired. If you are in doubt when selecting a place for installation,
consult your car dealer.
Make sure before drilling the holes that no electric cables, brake cables or similar can be
damaged.
When using tools for mounting your device, observe the safety instructions of the
manufacturer.
When installing the device, take into consideration the risk of accident which can arise from
devices being torn away in case of an accident. Therefore, you should secure every component
in a place where it cannot be dangerous to passengers.
The device can be attached to the dashboard with the enclosed installation angle or installed in a corresponding opening
in the dashboard.
Matching mounting and installation casings with a standard opening for installation instruments are available in retail stores
(partially also vehicle-specific).
• Select an appropriate installation location. The installation location must
be well visible from the driver's seat.
• When selecting the installation site, consider the required installation
depth. Especially ensure sufficient distance to moving vehicle parts (rods,
levers, etc.).
• Twist the attachment ring off the instrument and pull it out of the
installation angle.
• If applicable, attach the installation angle with 2 suitable screws on the
dashboard.
• Put the instrument into the installation opening and attach it by screwing
the attachment ring back on and tightening it by hand.
Change of the Illumination Colour/Illuminant Change
w w w. c o n r a d . c o m
w w w. c o n r a d . c o m
• Pull the illuminant fitting from the rear of the inline instrument.
• Push on one of the included coloured caps onto the illumination bulb.
• To change the bulb, pull it from the illumination fitting and insert a new one.
Version 07/10
• Insert the fitting into the in-line instrument again.
Connection
• Disconnect the negative pole of the on-board battery.
• Separate the connection to the generator and the consumers from the positive pole of the on-board battery.

• Connect the port marked with (+BAT) on the instrument
directly with the positive pole of the battery.
• Connect the port marked with (-ALT) on the instrument
with the previously separated leads to the generator and
the consumers.
• Connect the white cable on the inline instrument to the
power supply for the dashboard light (clamp 58).
• Connect the black cable on the inline instrument to the vehicle earth or an earth lead (clamp 31).
• Check the correct connection once again and then reattach the negative pole of the on-board battery.
• Check whether the ammeter and the illumination work. If a consumer is switched on while the engine is off, the
pointer of the ampere meter must point to the left (discharge of the on-board battery). If the engine is running, the
pointer of the ampere meter must point to the right (charging of the on-board battery).
Maintenance and Care
The outside of the product should be cleaned with a clean dry cloth or brush only.
Never use any aggressive cleaning agents or chemical solutions that may damage the surface of the housing.

Only an expert may connect the device, because almost the entire current of the vehicle flows
through the connection cables of the ampere meter. These cables are not secured via fuses so
that the vehicle may easily catch on fire in case of a defect (e.g. accidental earth).
To avoid shorts and any resulting damage to the device, the negative terminal (earth) of the car
battery has to be disconnected first.
Only connect the negative pole of the battery, when you have completely connected the system
and checked the connections.
You should only use a voltmeter or a diode test lamp for checking the voltage on the on-board
cables as normal test lamps consume excessive currents and can thus damage the electronic
system of the car.
When installing the cables, make sure that these are not squashed or scrape on sharp edges!
Use cable nozzles for passage points.
Only use vehicle cables with at least the diameter used between the generator and the on-board
battery for connection. Bell cord or wires etc. are not suited for installation in vehicles and
have an insufficient cable diameter.
You may also only use suitable car connection elements suitable for the cable dimension,
which must be installed with suitable tools on the cables.
Try to install the connection leads along the car's cable tree and avoid loose cable loops that
may become caught in the pedals of the vehicle. This may lead to life-threatening situations
while driving.
The lead to the ignition MUST stay directly connected to the on-board battery, as this carries
much stronger currents than the ampere meter can display.
