Included Items

1 StroboPlus HD
1 Owner’s Manual
1 3.7V Lithium Ion Battery
1 Micro USB Cable

Power

The StroboPlus™ contains a powerful internal rechargeable lithium-ion battery. Before initial use, this battery will
need to be installed and charged fully, using either a USB power adapter or by connecting the StroboPlus to a
computer USB port via the USB cable. The StroboPlus can run off of USB power alone. Charging time is
approximately 2 hours. To conserve battery life, the StroboPlus will power off after 10 minutes of inactivity if not
in use. In addition, the LCD backlight will turn off after 10 seconds of inactivity. If the battery voltage becomes

too low, the StroboPlus will power off to protect its lithium-ion battery. If required, additional rechargeable
lithium-ion batteries can be purchased from the Peterson Online Store at www.PetersonTuners.com. In situations
where there is no access to a computer, a power adapter plug is also available from the Peterson Online Store.

Tripod mount

The StroboPlus has a standard tripod screw mount on the back so that you can use a variety of connection devices
to mount it on an instrument, mic stand or other convenient place. See the Peterson website to purchase a holder
appropriate to your needs.

Optional Accessories

Optional accessories for the StroboPlus include the StroboPlus Pitch HolderTMmounting bracket, StroboPlus
adapter for StroboFlip style Pitch Holder, TP-3 Tuning Pickup, additional rechargeable 3.7V Lithium Ion battery
and A/C adapter. These items are all available from the Peterson Online Store at www.PetersonTuners.com or
from your local Peterson Dealer.

Reading the Strobe Display

Your tuner’s display features two concentric strobe bands. Underneath the strobe bands, the note name is
displayed as a large letter along with a number indicating the octave from which it is derived. To tune, play a note
on your instrument and carefully adjust its tuning until the strobe bands stop moving or are “caged“. If the note
you are tuning is too sharp, the bands will drift to the right; if flat, they will move to the left.

New to Strobe Tuning?

If you are new to strobe tuners, you’ll notice that they are much more sensitive and accurate than your previous
tuner. If you are tuning a stringed instrument, you may need to adjust your “touch“ when you pluck a string to
tune. Initially, instead of a plectrum or pick, use your finger or thumb to gently pluck the string or simply reduce
the volume of your instrument until you become accustomed to tuning accurately. In the case of guitars and
basses, check your instrument’s intonation before tuning, see “Guitar & Bass Intonation Tips” elsewhere in this
manual for instructions on how to do this. Owning a Peterson means you can do your own set-up work on your
instruments.

User Interface

How to Turn StroboPlus™ On

Press and hold the power button until your StroboPlus powers on. If the battery is drained, StroboPlus will require
a few minutes of charge time before it can be powered on.

How to Turn StroboPlus Off

Press and hold the power button for two seconds.

Mode Select

The mode button selects which mode the StroboPlus™ operates in. Three modes are possible: Strobe Tuner,
Audio Tuner, or Metronome (if upgraded). The metronome operation is covered in its own instruction manual
which is provided as an electronic download with the purchase of the upgrade. This manual covers the tuner
functions only.

How to Edit Parameters/ User Interface

The StroboPlus has a very intuitive interface that makes it easy to quickly change any parameter that you desire.
The user-controlled parameters can be selected and edited when the menu is active. The menu is active when an
item is blinking on the screen. Adjusting the select knob will affect the blinking item.

There are two basic menu types:

Select Menu

Rotate the select knob to cycle through the available parameters. The selected parameter is indicated by its
descriptive icon blinking. Pressing the select knob then enables the Edit Menu for the selected parameter.

Edit Menu

Once you are in the Edit Menu, the parameter value to be changed will blink. Rotating the select knob while in the
edit menu changes the value of the blinking parameter. After you finish changing that value, press the select knob
or simply wait a few seconds for the screen to return to normal operation.

From the home screen (nothing blinking), rotating the select knob activates the Select Menu starting with the last
selected parameter.

From the home screen (nothing blinking), pressing the select knob activates the Edit Menu for the last selected
parameter.

After a few seconds of no user inputs to either the Select Menu or the Edit Menu, the menu will automatically time
out and the screen will return to normal use operation. To force the menu to time out and exit immediately, press
and release the power button from any menu.

Advanced User Controls

Locking the Active Edit Menu

To prevent the time-out and automatic closing of the Edit Menu, first activate the Edit Menu. Then, press and hold
the select knob for two seconds. The screen will return to normal, however, the selected parameter will continue to
blink and the select knob can be used to edit that parameter indefinitely for on-the-fly adjustments. The automatic
menu time-out will be disabled. To exit the locked Edit Menu, press the select knob and the screen will return to
normal.

Locking a parameter in the Edit Menu can be handy when you desire to edit that parameter over a period of time.
For example, if you want to measure the cents offset of an input signal, locking the cents parameter in the Edit
Menu will allow for continued adjustments without the Edit Menu timing out.

Selectable Parameters

Transpose/Drop/Capo - choice of 12 (factory default is 0 or C). This control is used to help players of non-C

instruments such as saxophone (Eb), French horn (F) and trumpet (Bb) to transpose notes when reading from C
notation. It is also used for stringed instruments to allow simple drop tuning or capo tuning without having to
transpose the notes in your head.

Concert A Reference Pitch- Range: 390Hz to 490Hz, adjustable in 0.1Hz increments.
Cents – Range of +/- 50 cents in 0.1 cent increments. This control adjusts the target that the tuner tunes to by very

fine increments of 1/10 of one cent. This is valuable if you want to determine how far out of tune a particular
instrument is or if you want to chart the tuning of a particular instrument. To determine the exact pitch, play a
note, then rotate the select knob while the cents value is flashing until the strobe image appears to be immobile.
The cents value on the display will show the offset of the note played.

Manual Note Select – Default settings are auto note select in strobe tune mode and manual note select in audio
tune mode. Press the man/auto button to change this setting.

Presets

Creating a New Preset

When your tuner displays a combination of Sweetener, Hz and Transpose values that you wish to save as a preset,
press and hold the preset/store button until the word “Preset”, a number, and the word ADD or SAV (“save”)
appear. If other presets have already been saved and you wish to create an additional one, turn the encoder knob
until the word “ADD” instead of “SAV” is shown. This will also display a preset number that has not already been
used. Press the preset/ store button again to confirm. The display will briefly show a circular animation to indicate
that your StroboPlus is saving your preset.

Overwriting an Existing Preset

To store the displayed combination of Sweetener, Hz and Transpose values by overwriting the values already
assigned to a particular preset number, press and hold the preset/store button for two seconds. Rotate the encoder
knob until the preset number you wish to edit is displayed, along with the abbreviated word “SAV”. Press the
preset/ store button momentarily. A circular animation indicates that your values are saved to that preset number.

Deleting an Existing Preset

To delete a preset that was previously created, momentarily press the preset/ store button. Rotate the encoder
knob to display the preset number that you wish to delete, then press and hold the encoder knob for a few seconds.
The abbreviated word “DEL” will appear for a few seconds as you continue to hold the knob. When “DEL”
disappears, your preset will have been deleted and all higher-numbered preset combinations shifted to a lower
preset number accordingly.

Recalling a Preset for Use

To use a combination of Sweetener, Hz and Transpose values that was previously saved as a preset on your
StroboPlus, momentarily press the preset/ store button. Turn the encoder knob to display the preset number you
wish to recall. A moment after you stop turning the encoder knob, the display will change from the preset number
to the values associated with that preset. To begin using those values, simply wait a few seconds without turning
or pressing the encoder knob, or to immediately accept the displayed values momentarily press the power button
once. Presets can also be created on a computer for downloading by visiting www.PetersonTuners.com/connect.

Audio Tuner Mode

Your StroboPlus™ has a built-in speaker and a headphone audio output for use as an audio tone generator. To use
this feature, press the mode button once or twice until only the far right and far left sides of the strobe pattern are
shown. The manual note select mode is automatically activated to let you choose your desired note and octave. In
order to begin hearing the tone or stop the tone output, press the start button.

Note: It is possible to select both the note and the octave from the edit menu when in manual note select mode.

All other settings, such as Transpose, Concert A and Sweeteners™/Temperaments are also selectable for your
audio tuner from the edit menu.
The speaker is disabled when a plug is inserted into the headphone output.
The tone/voice that is heard can be selected by editing the voice selection.

Configuration Menu

This menu is used to reset your StroboPlus to factory default settings and to determine the firmware and hardware
version. To enter the configuration menu press the power button and the mode button at the same time.
The first setting to show will be C, indicating the configuration currently loaded.
FDR= Factory Default Reset
USR= User configured. This indicates that there has been a user configuration created on the PetersonConnect™
site and loaded to the device. To return to the factory default, select FDR with the selector knob and press in. If
only dashes “-- -- --“ are shown there is no user configuration on your tuner.

Rotating the selector knob will next show F and the firmware that is currently installed in your tuner. There will
be three numbers displayed; combined they indicate the installed firmware version.
H indicates the hardware version of the tuner.

To exit this menu, press the mode button.

This web portal allows you to create presets from your favorite settings, determine which Sweeteners and
temperaments will show on your tuner and save and trade custom Sweetener™ settings. Your settings will be able
to be loaded onto any Peterson tuner which has a USB port. When you register your tuner, all settings will be
stored both at this portal and on your device. When you connect the tuner via the USB cable to a computer
connected to the web, the PetersonConnect site will determine if there are any firmware updates or configuration
changes that need to be loaded. Visit www.PetersonTuners.com/connect .

GUITAR & BASS TUNING TIPS:

If you use a tuning which is not listed as a Sweetener, use EQU. Tune up to pitch, never down. Use fresh strings.

GUITAR & BASS INTONATION TIPS

After deciding on string gauge, setting string height (nut & bridge) and neck relief—factors that affect the
instrument’s intonation considerably—the individual string lengths need to be adjusted. For this task, use equal
temperament (EQU).

• Lower the pickups away from the strings to avoid "doubling" and electromagnetic pull.

• Lay the guitar flat on a bench to adjust it, but always check the intonation with the instrument in the playing
position, as the readings will be visibly (and later audibly) different. You should always aim to freeze or "cage"
the image on the strobe tuner display; the less movement the more accurate the results.
Where setting the intonation is concerned, an often-used technique is the 12th fret & flageolet comparison method.
In this method, the flageolet or "harmonic" of the 12th fret is compared to the fretted string at the 12th fret, and
saddle position is adjusted as follows:

• If the fretted note is flat compared to the flageolet note, move the bridge saddle forward to shorten the string.

• If the fretted note is sharp compared to the flageolet note, move the bridge saddle back to lengthen the string.

• Adjust until both fretted note and flageolet are identical in pitch. While this is a common system, it is not always
the most satisfactory. One popular alternative is to adjust each string so that it is in tune at two points an octave
apart from each other on the fret board using a strobe tuner. Using the 5th and 17th fret as an example:

• Tune a string at the 5th fret.

• Check the string at the 17th. If sharp, move the saddle back, thus lengthening the string. If flat, shorten the string
by moving the saddle forward. Remember to fret the string using the pressure that you would normally apply
while playing.

• Keep repeating this process until each string is in tune as much as possible at both the 5th and 17th frets.
This method takes time, and has to be repeated if you change string gauges, but if properly executed, yields very
satisfactory results. Now, before you play music with a lot of 5ths on your guitar (e.g. power chords), tune the
instrument using the GTR, BAS, P5TH or G5TH setting, depending on which model of strobe tuner you own,
otherwise use the EQU (default) setting to tune your guitar. The methods above are within anybody's reach; all
you need are your ears and your Peterson strobe tuner!

PEDAL STEEL TUNING TIPS:

If required, multiple pitches of the same note in the same or different octaves within a single Sweetener can be
programmed using the StroboPlus Editor on www.PetersonTuners.com/connect. A bracket for mounting the
StroboPlus on a steel guitar is available from www.PetersonTuners.com. Owners of the Peterson StroboFlip can
use the StroboFlip mounting bracket with the addition of a universal joint available also from the Peterson online
store.

HARMONICA TUNING TIPS:

The included settings are the official Hohner values for their range of harmonicas. To apply a Sweetener to a
harmonica in a key other than C, use the transpose feature.

ACCORDION TUNING TIPS:

The included settings are general values for a number of musette styles. General good practice is to avoid all
unnecessary structural damage to the reed when tuning, remove material in a straight line along the length of the
reed. To apply a Sweetener to an accordion in a key other than C, use the transpose feature.

HARP TUNING TIPS:

Be careful to maintain an even tension on the harp’s frame when tuning, this is especially important when the
instrument has been detuned due to transport etc. Starting with the longest string, tune each note in all octaves
before moving to the next note. Finally, check and retune any strings which may have been affected by the
changing tension of other strings while tuning.

MARIMBA/XYLOPHONE

The presets for marimba and xylophone are intended for monitoring the instrument’s condition, for correct bar
retuning and regulation, consult the instrument’s manufacturer.

PIANO TUNING TIPS

Do not attempt without having basic tuning skills and technique. Learn the correct use of mutes and a tuning
hammer before attempting to tune your piano, if in doubt, consult a qualified piano technician. For electric pianos,
use the EQU setting if a stretch tuning is not desired.
