message and menu structure (as shown).
Each PowerLink transducer is programmed at the factory to identify itself by model,
frequency, serial number and type. The operator may select the factory default setup for each
transducer type in the event that an instrument setup has not been associated with that
transducer.
The stored program feature is tied into the program store and recall features of the instrument.
This makes stored programs associated with transducers look the same to the operator as other
stored programs.
Before any stored transducer programs can be recalled, a Olympus NDT transducer must be
connected to the instrument and identified. Multiple programs are associated with each
transducer and the operator is allowed to select from the programs stored.
When a transducer linked through PowerLink is removed and replaced with
another transducer, the Sonic
®
1200S/HR instrument MUST be recalibrated, or the
new transducer relinked before testing.

PowerLink™ Connection
®
After connecting a Olympus NDT transducer to your Sonic
1200S/HR instrument, touch and
hold the transducer to the PowerLink contact disc on your EL/LCD display for approximately
4 seconds, or 2 beeps. If contact is not
maintained for the proper amount of time, the screen
will show the PowerLink display with N/A parameters. In this case, try again, until the
PowerLink connection is complete and parameters are displayed.

identified transducer, the number of the next empty storage location will be displayed.
Store/Recall
Instrument settings associated with the identified transducer are stored to or recalled from the
selected program location. If the location is empty, the operator is allowed to store the
instrument setup. Whenever a transducer setup is recalled, the current instrument settings are
overwritten and cannot be recovered unless the setup was previously saved.
Erase
Allows the operator to erase the selected transducer setup. This needs to be done only if the
storage location is to be reused. An ENTER confirmation will be required from the operator
before the program location is cleared. An erased location cannot be recovered.
Name
Allows the operator to enter a name of up to 26 characters to identify the setup. Only program
locations which are not empty may be named.

1.6 Power Requirements
As a fully portable inspection instrument, the Sonic® 1200S/HR relies on two nickel-metal
hydride (Ni-MH) batteries (one Lithium Ion (Li-Ion) battery on ë+’ models) as the primary
source of power. The battery compartment is located at the rear of the unit and is conveniently
accessed by loosening the two quick release screws and removing the battery cover.

The batteries provided with the Sonic
®
1200S/HR instrument are small, lightweight, portable,
and capable of delivering long service life between recharges or battery replacement.
A Universal Battery Charger (UBC) unit is pro vided wi th the S onic
®
1200S/HR for recharging
the batteries while in the instrument or external battery pack and allowing the Sonic
1200S/HR to be operated from AC line power. The UBC unit auto senses 90-264 VAC, 47 to
12 Chapter 1
®
63 Hz power.
®
The condition of the batteries used in the Sonic
1200S/HR is monitored by the charger. Fully
discharged Ni-MH batteries will require approximately 8 hours for a complete charging cycle
(4 hours for each battery), while Li-Ion batteries will require approximately 6 hours. The
charger will not charge batteries which are too hot, too cold, or too deeply discharged.
For optimum performance:
• Refer to the manual that came with your instrument or charger for charging instructions.
• When you charge your battery for the first time, your charger may indicate that charging is
complete after just 10 to 15 minutes. This is normal and can happen with all rechargeable
batteries when first charged. Simply remove the battery and then repeat the charging
procedure.
• Upon first use, or after prolonged periods of storage, you may need to charge and
discharge your battery two or three times before obtaining optimum performance.
• It is best to charge the battery at room temperature ranging between 59°F (15°C) and 86°F
(30°C).
• It is normal for the battery to become warm during charging or after use.
• It is not necessary to fully discharge your battery before charging. You can top-off the
charge at any time.
• A charged battery will gradually lose its charge if left in storage. We therefore suggest that
you top-off the charge before use.
• Remove your battery from the equipment, charger or AC adapter when not in use. Store at
room temperature in a dry place.
To avoi d damage to the battery:
• Do not drop the battery or subject it to mechanical shock.
• Use the battery only with equipment that specifies its use.
For safe operation:
• Do not disassemble or attempt to open the battery under any circumstances.
• The battery can explode, leak, or catch on fire if heated or exposed to fire or high
temperatures.
• Do not short circuit the battery by directly connecting the metal terminals (+, -). Be certain
that no metal objects such as coins, paper clips, etc., touch the terminals.
• Only use the charger recommended by the device manufacturer.
Preparation for Operation 13
Note that internal memory batteries should be changed as a preventative maintenance feature
every two (2) years.
It is recommended that you refrain from operating the instrument while recharging
fully discharged batteries. The charge may be incomplete and thus activate the temperature
fault indicator — as a result, battery life and instrument run time may be shortened
significantly. If the indicator is activated, shut off the instrument and disconnect the
instrument from the charger. Allow the batteries to cool, then reconnect the charger to the
instrument to start a new charge cycle.

Li-Ion Battery
Fully charge battery before first use. Instrument run time is affected by
variables such as: quality of charge, age of battery, and display type. The battery
charge indicator on the display is an estimation of expected run time. Instruments are
equipped with a circuit that shuts off power prior to full discharge. Battery life is
affected by: number of charge/discharge cycles, storage conditions, temperature, and
use. Batteries stored for extended periods of time (mon ths/years) without use may no
longer recharge. Under normal use Nickel-Metal Hydride (NiMH) batteries last
approximately 500 charge/discharge cycles, while a Lithium-Ion battery will last
approximately 300 cycles. Expect to change the batteries after 1 year of heavy use or 3
years of light use under normal conditions. Batteries must be disposed of in
accordance to local law or returned to Olympus NDT Instruments. Olympus NDT
Instruments does not warranty batteries, due to op erating conditions beyo nd Olympus
NDT’s control affecting battery life.
Dual Ni-MH battery run time for the Sonic
is at least 10 hours. Dual Ni-MH battery run time for the Sonic
®
1200S/HR with the LCD module
®
1200S/HR with the
electroluminescent (EL) display module at 100% intensity, is at least ten (10) hours.
1.9 Charging the Ni-MH/Li-Ion Battery Pack
Proper charging of the Ni-MH/Li-Ion battery packs is critical for overall life and performance.
The Universal Battery Charger (UBC) will charge either the Li-Ion battery used in the single
battery instruments or both Ni-MH batteries in the dual battery instruments. Th e selection of
charging system is made by the detachable cable to instrument connection. The two instrument
categories have very different, non-interchangeable connectors to prevent an incorrect
16 Chapter 1
connection. Note that the UBC to instrument cables are detachable and replaceable as catalog
items.
The charger also functions as a battery eliminator to operate the instrument from the AC power
source. Batteries do not have to be installed to operate the instrument from AC. When operated
from the UBC without a battery installed in the instrument, disregard any battery charge status
indications from the UBC charge indicator. The instrument can be operated while a Li-Ion
battery is being charged, but is not recommended while charging Ni-MH batteries.
1.9.1 UBC Specifications
Power Requirements: 100-240 volts, 47 to 63 Hz.
The UBC contains an internal fuse.
Nickel Metal Hydride battery charging system: Sequentially charges two DR-35 style (Ni-
MH) batteries. Charges at approximately 1 ampere rate. A pair of 3.8 AH batteries take about 8
hours to fully charge.
Lithium Ion battery charging system: Charges one Li-Ion battery . Char ges at approximately 1.5
ampere rate. A 6.6 AH battery charges in approximately 6 to 8 hours.
Temp erature range: Batteries should be charged between 40° to 100° F (4° to 38° C) for best
results. If the batteries become too hot, the battery charger will terminate the charging process.
If the batteries are being charged while using the instrument, the heat from normal operation of
the instrument may cause the battery charger to terminate the charging process before the
batteries are fully charged.
To start a charge cycle, the charger can be reset by disconnecting and reconnecting either the
instrument or AC power to the UBC.
1.9.2 Charger Status Indicators
The charger status is indicated by a red/green LED lamp.
The light may blink red or green for a few seconds when first connected to either AC power or
an instrument. It will then light steady red as the charging process starts. This is normal as the
circuits initialize. If a problem is detected during charging, the light will blink red. Reset the
charger by disconnecting the AC power for a few seconds and re-connect. If the problem
persists, service is required.
Preparation for Operation 17
1.9.3 Charger Operation Instructions
1. Connect the UBC to a source of AC power.
2. Connect either the single battery Li-Ion or dual Ni-MH cable to the instrument and
charger.
3. Ni-MH batteries: The red charging indicator will light, indicating that the batteries are
charging. The charger will charge one battery and automatically switch to the second
battery when the first is charged. The indicator will turn green when both batteries are
charged. If only charging one battery, the green charge complete indicator will not light.
The red charging lamp will go out when the battery is charged. Ni-MH batteries generate
heat while in use, especially during charging. This heat, added to that generated by the
instrument, can cause the charger to terminate the charge cycle before the batteries are
fully charged. It is not recommended that NiMH batteries be charged while operating the
instrument. This is not due to power supply capacity, but heat build up within the
instrument.
4. Ni-MH batteries receive a continuous trickle charge whenever they are connected to the
UBC. If the instrument is being used on AC power for long periods of time, the batteries
should be removed from the instrument. They should be re-installed and recharged and
then removed at regular intervals to keep them fresh. 30 to 60 day intervals are
recommended.
5. Lithium-Ion batteries: The red charging indicator will light, indicating that the batteries
are charging. The indicator will turn green when the battery is charged.
6. The charger circuits can be reset if a problem occurs by disconnecting either the AC power
for at least 15 seconds or the UBC to instrument cable (either end) and then re-connecting.
Li-Ion batteries are sensitive to over charge. For this reason, the full charge detection
system is very sensitive and may shut off the charging process before the charge is
complete. If this happens, reset the charger. During use, the UBC case will become warm.
7. The charger is designed to shut off after a Li-Ion battery is fully charged (the instrument
power is always available). It does not provide a maintenance charge, because Li-Ion
batteries can be damaged by trickle charging. To recharge a Li-Ion battery, reset the
charger by either disconnecting the AC supply or instrument for a few seconds to reset the
charger circuit. Li-Ion batteries have a long shelf life and should only require recharging
after many months of storage if not used.
1.9.4 Battery Safety
Old batteries that will no longer deliver satisfactory service shoul d be disposed of in a legal
and environmentally friendly manner. In the USA, call 1-800-8BATTERY for the nearest
battery recycle center. If there is no convenient battery recycle center, the batteries may be
returned to Olympus NDT Instruments for proper disposal.
18 Chapter 1
No battery should be disposed of by fire or abused by puncturing its case or disassembled. All
batteries contain potentially hazardous chemicals, however neither Ni-MH or Li-Ion batteries
contain lead, cadmium or mercury.
Lithium-Ion batteries contain an internal safety circuit. Both Nickel-Metal Hydride and
Lithium-Ion batteries contain internal fuses. If this fuse blows or the safety circuit shuts off the
battery, the battery is no longer fit for service. The internal safety circuits are not serviceable.
Olympus NDT Instruments purchases batteries from reputable vendors. Although Olympus
NDT Instruments tests and qualifies the batteries for use in Olympu s NDT prod ucts, Olym pus
NDT can not guarantee that batteries obtained from other sources will be satisfactory or that
Olympus NDT supplied batteries will work in non Olympus NDT products. The Universal
Battery Charger is designed to work with Olympus NDT equipment only.
1.9.5 Battery Characteristics
Most batteries will not deliver their full charge on first use or after extended storage. Use them
until the instrument shuts off after full discharge (automatic low battery shut off) and recharge.
This will recondition the battery. This is especially prudent with Ni-MH batteries.
The battery is considered by the manufacturer to be beyond its service life when it delivers less
than 80% of its rated capacity. A Ni-MH battery should have a life expectancy of 500
charge/discharge cycles and Li-ion batteries, 300 cycles. These specifications are obtained
under laboratory conditions and real world usage will be different.
Battery life will be prolonged if they are not subjected to harsh temperatures, either hot or cold,
and stored in a charged condition. Ni-MH batteries should be recharged periodically. They
should not be left in the instrument when not being used over extended time.
Batteries have reduced capacity at low temperatures. Exact percentages are not specified but
operation below freezing is not recommended.

1.10 Operating Environment
The Sonic® 1200S/HR is designed as a portable instrument and, as such, requires no special
site preparation before operation. When operating, the in strument should be firmly support ed
to prevent damage due to a fall. The unit should be protected as much as possible from water or
chemical splashes, rapid temperature changes, and should be operated away from large
electrical equipment that may interfere with the operation of internal circuitry.
