Setup
1. Charge Battery - The Altissimo battery was fully charged at
the factory, however, the battery may have discharged during
shipping and storage. It is recommended to leave the charger
connected for at least fourteen hours. The charging circuit is
designed to provide a maintenance charge to the battery and
may remain connected for the duration of use. The tool will
remain ON while the charger is plugged in regardless of the
position of the Battery Power ON/OFF Switch.
Removing the Charger plug and reinserting will initiate
another charge cycle depending on the state of charge of the
battery.
If the Low Battery ICON comes on, locate the charger and
plug it into the Power Jack on the right side of the Display.
(Figure 3)
See Page 19 for additional Battery Charging information.
CAUTION - See Care and Maintenance section for necessary
precautions.
2. Move Slide - Rotate the Probe and Belt Locking Knobs
counterclockwise. Using the Coarse Adjuster Knob move the
Probe Mounting Arm to the center of travel. Re-lock the Belt
and Probe Locking Knobs. (See Figure 4)
3. Mount Probe Holder - Mount the Probe Holder onto the
Mounting Arm and tighten the screw firmly. (See Figure 5)
Note: Make sure the Probe Holder is mounted vertically.
4. Mount Probe - Mount the Probe into the Probe Holder and
tighten the screw firmly. (See Figure 6)
Note: Make sure the Probe Tip is oriented downward so that
the Probe Holder or the Probe Shank does not hit the surface
plate.
5. Clean - Clean the Probe Tip and the Top and Bottom
measuring surfaces of the Calibration Block with Isopropyl
Alcohol and lint free cotton cloth. (See Figure 7)
6. Lifting - Care should be taken when lifting the Altissimo.
Lock down the probe and belt (See Figure 4). Firmly grip the

Probe Calibration
Power On - Turn the Power on, if using the Battery for power place
the Battery Power On/Off switch to the 1 position or plug the charger
in and the unit will power regardless of the Battery Power On/Off
Switch position.
The display comes on in Height Mode and prompts for Point 1 (Pt 1).
(See Figure 8)
Note: The Altissimo can be used to measure heights even if the Probe
is not calibrated. See Measuring Modes – Height Section.
Figure 8
Probe Diameter Calibration – If the Probe Symbol is Flashing in
the upper left corner of the Display, it will be necessary to Calibrate the Probe Diameter. (See Figure 9) The Probe
Diameter must be recalibrated when the Altissimo is first received and periodically thereafter, especially when
measuring conditions change.
Press the SETUP Key and the Probe Calibration Mode Icon will light. The display will ask for Point 1 (Cal 1).
Position the Calibration Block under the Probe. Using the Coarse Adjuster Knob move the probe down onto the
Upper Measuring Surface until the tool beeps. Move the Probe clear of the surface. The display will ask for Point 2
(Cal 2). Similarly measure the Lower Measuring Surface of the Calibration Block. Measure the Upper and Lower
Measuring Surface a second time.
Note: In order to calculate the diameter of the probe the first and second measurements must be taken in opposite
directions, the third and fourth measurements must also be taken in opposite directions.
Accept the Calibration - After measuring each surface twice, the Altissimo will display a number which is the
Deviation of the Probe Calibration. The deviation is the repeatability of the points taken during Probe Calibration.
This provides a measure of the quality of the measurements. If the Deviation is sufficiently low, under .0002”
(.004mm), then Press the F5 Function Key ( ) to accept the value. (See Figure 10) The Probe Calibration Icon
stops Flashing and the top and bottom "Hit" bars are Flashing indicating measurements can be made in either
direction.
Note: If the Deviation is high, over .0002” (.004 mm), then check the tightness of the Probe Arm and Probe. Check
the cleanliness of the Probe Tip and Calibration Block. Make sure that the Probe and Belt Locks are fully unlocked.
Then recalibrate the Probe.
Important: The Altissimo will store the Calibrated Probe Diameter even after it is turned off. The Probe must be
recalibrated each time it is changed or repositioned. See Setup Section for instructions on other Probe Diameter
Calibration Options.
Starrett Altissimo Operation Manual Page 5 CAT 2000-24
Establishing a Datum
Measure Datum – If the Datum Symbol is flashing in the upper left corner of the Display then a Datum will need to
be established. Using the Coarse Adjuster Knob bring the Probe in contact with the surface plate or other datum
surface until it Beeps. (See Figure 11) Move the Probe clear of the surface. Press the F1 key to set the Active Datum
to 0 at the last measured point. (See Figure 12)
Note: If the probe is not calibrated the Altissimo may be used in the Unidirectional Height mode. Simply take a
measurement in either direction, Press the F1 Key to set the Active Datum to 0. The tool will only measure in the
direction that the initial point is measured in. See Measuring Modes – Height Section.
If a Datum is already established, then select the appropriate Measurement Mode using the Keys to the right of the
Display. Any of the following measurements may be used to establish a Datum: Height, Center, Max or Min.
Measure the Datum and verify that the value in the Display is the value to be used for the Datum. If the Diameter or
TIR Measurement Mode is selected, it will be necessary to use the Hot Key on the Base or the F5 Key () on the
Display to change the Display Value to Center, Max or Min before a Datum can be stored.
Store Datum - Simply press the F1 Key while displaying any of the above measurements and the Active Datum will
be set to 0 at the Measured Feature.
Note: Two Datums (A and B) and a Preset (P) may be stored. The Active Datum appears as a letter (A, B or P) in
the Datum Symbol in the upper left corner of the display. The Active Datum may be changed at any time by
pressing the F2 Key (ABP).
Store Preset – If the Preset is active, a P will appear in the Datum Symbol in the upper left corner of the Display.
When the F1 Key is pressed the Preset Value will be displayed. The Preset Value may be changed at this time using
the F1 through F4 keys. After verifying that the preset value is correct press the F5 key and the Datum will be set to
the Preset Value at the Measured Feature.
Starrett Altissimo Operation Manual Page 6 CAT 2000-24
Measuring - Height
Height Measuring Mode : The Height Mode can be used to measure the Height of either the upper or lower
surface of a part. Press the HGT Key to the right of the Display to enter this mode. The tool will request a data point
(Pt 1). Using the Coarse Adjuster Knob, bring the Probe into contact with the surface to be measured until it Beeps.
Move the Probe clear of the surface.
Note: If the probe has not been calibrated the Altissimo will only allow measurements in one direction, the same
direction as the Datum was taken.
The display will show the Distance between the Datum and the Measured Surface. If you have measured more than
one feature the Display will show a second Icon above the Measurement Value. Press the Hot Key on the Base or
the F5 Key on the Display to switch the measured value between Height and Distance to Last Feature.
In Figure 13 and 14:
Point 1 is taken, the Height Value is 2.0000, the Height Icon is flashing.
Point 2 is taken, the Height Value is 3.0000, the Height Icon is flashing, Dist. Between Features Icon is on.
Press the HOT Key or the F5 Key to toggle between the Height and The Distance Between Features Values. The
Active Value is the Icon that is Flashing.
Unidirectional Height Measuring Mode: If the probe is not calibrated, the Altissimo can be used in the
Unidirectional Height Mode. When the Probe Symbol is flashing in the upper left corner of the Display, simply take
a measurement in either direction, Press the F1 Key to set the Active Datum to 0. Only one “Hit” bar will be
displayed with the Probe Calibration Icon. (See Figure 15) The tool will only measure in the direction that the initial
point was measured in. To clear the Probe Calibration see Setup Modes – Probe Calibration Section.
Note: When the Probe is not calibrated, the Altissimo can only be used in the Height and Continuous Modes.
Starrett Altissimo Operation Manual Page 6 CAT 2000-24
Measuring - Center
Center Measuring Mode : The Center Mode can be used to measure the Center of a Bore, Slot or Rib. Press the
CTR Key to the right of the Display to enter this mode. After probing points on opposite sides of the Feature the
Altissimo automatically calculates and displays the Center of the Feature.
The Display will request Point 1 (Pt 1). Locate the probe approximately in the center of the Feature to be measured.
Using the Coarse Adjuster Knob, bring the Probe into contact with either the lower or upper surface of the Feature to
be measured until the tool Beeps. The display will request a second point (Pt 2). Without moving the part or the tool,
bring the Probe into contact with the opposite surface of the Feature until the tool Beeps. Move the Probe clear of
the surface.
Note: If measuring a Rib it will be necessary to move the part or the tool to probe the opposite side. Care should be
taken to reposition the probe as close as possible to the point opposite the first point.
The display will show the distance between the Datum and the Center of the Feature. Press the Hot Key on the Base
or the F5 Key on the Display to switch the measured value between the Center and the Distance Between Last Two
Points. If you have measured more than one feature the Display will show a third Icon, Distance to Last Feature.
In Figure 16 and 17:
Point 1 is taken, the Tool requests Point 2 (Pt 2).
Point 2 is taken, the Center Value is 5.0000, the Center Icon is on, Distance Between Points Icon is flashing.
Point 3 is taken, the Tool requests Point 2 (Pt 2).
Point 4 is taken, the Center Value is 7.0000, the Center Icon is on, the Distance Between Points Icon and
the Distance Between Feature Icon are flashing.
Press the HOT Key to toggle between the Center, the Distance Between Points and the Distance Between Features
Values. The Active Value is the Icon that is Flashing.
Note: The Distance Between Points is used to measure the Slot Width (distance between points 3 and 4). In the case
of measuring a Circle (points 1 and 2) the value is meaningless since it is unlikely that the measurement will be
taken in the exact center of the Hole.
Starrett Altissimo Operation Manual Page 8 CAT 2000-24
Measuring - Diameter
Diameter Measuring Mode : The Diameter Mode can be used to measure a Diameter of a Shaft or Bore or the
Height of a Slot or Rib. Press the DIA Key to the right of the Display to enter this mode. After scanning the upper
and lower surface of the part, the Altissimo automatically calculates the Diameter.
The Display will request Scan 1 (Scn 1). Locate the probe to one side of the center of the Hole or Boss to be
measured. Using the Coarse Adjuster Knob, bring the Probe close to either the lower or upper surface of the Hole to
be measured. Pull out the Adjusting Knob to engage the Fine Adjust mechanism and move the probe onto the
surface until the tool beeps. Slide the probe across the High or Low point of the Hole. (See Figure 18) Move the
Probe clear of the surface; the tool will beep twice as the probe is retracted. The Display will request a second Scan
(Scn 2).
Bring the Probe into contact with the opposite surface of the hole or slot until the tool beeps. Slide the probe across
the High or Low point of the Hole. (See Figure 18) Move the Probe clear of the surface; the tool will beep twice as
the probe is retracted.
The display will show the Diameter of the Hole or Boss. (See Figure 19) Press the Hot Key on the Base or the F5
Key on the Display to switch the measured value between Diameter and Center of the Hole. If you have measured
more than one feature the Display will show a third Icon, Distance to Last Feature.
Note: When using the Diameter Mode to measure very small
diameters where the probe cannot be swept very far past the top
or bottom of a hole or boss, or to measure a slot width, it is best
to end the scan by pressing the Hot Key rather than retracting the
probe from the surface. This will provide the most accurate
measurements.
Note: If the tool beeps three times before you end the Scan you
have exceeded the High or Low Limit of the Scanning Range.
(See Figure 20) Press CLEAR Key to clear the last data point and
remeasure the surface. You can monitor your position within the
Scanning Range by observing the Scanning Meter on the Left
Side of the Display Screen.
Tip: When Measuring Diameters it is helpful to set the Belt Locking Knob to drag a little on the belt. This will
prevent the probe from moving while scanning and eliminate the need to engage the Fine Adjust Knob. Tightening
the Belt Locking Knob too much will prevent the probe from moving.
Tip: For quick measurements, the probe can be brought into contact with the surface to be measured by using the
Coarse Adjuster Knob. Try not to move the Knob while scanning the surface. After scanning the surface use the
Knob to retract the probe. This will provide slightly reduced accuracy but greatly speed up measurements.
Starrett Altissimo Operation Manual Page 9 CAT 2000-24
Measuring - TIR
TIR: The TIR mode can be used to measure TIR of either the upper or lower surface of a part. Press the TIR Key to
the right of the Display to enter this mode.
The Display will request Scan 1 (Scn 1). Using the Coarse Adjuster Knob, bring the Probe close to the Surface to be
measured. Pull out the Adjusting Knob to engage the Fine Adjust mechanism and move the probe onto the surface
until the tool beeps. Slide the probe across the High or Low point of the Hole. Press the Hot Key to end the scan.
The display will show the TIR of the measured Surface. Press the Hot Key on the Base or the F5 Key on the Display
to switch the measured value between TIR, MAX and MIN. (See Figure 22) MAX is the distance from the Active
Datum to the Point furthest away. Min is the Distance from the Active Datum to the point closest. When either the
MAX or MIN are selected using the Hot Key, the F1 Key will allow setting the Active Datum to either feature.
Tip: When Measuring Surfaces it is helpful to set the Belt Locking Knob to drag a little on the belt. This will
prevent the probe from moving while scanning and eliminate the need to engage the Fine Adjust Knob.
Note: Retracting the probe from the surface will terminate the Scan, however, the most accurate results will be
achieved when the Hot Key is used to terminate the scan.
Tip: The TIR mode can be used to measure the high or low
point of a Diameter or other surface. The Datum can then
be set to the Max or Min Value. (See Figure 21)
Note: If the tool beeps three times before you end the Scan
you have exceeded the High or Low Limit of the Scanning
Range. (See Figure 23) Remeasure the surface. You can
monitor your position within the Scanning Range by
observing the Scanning Meter on the Left Side of the
Display Screen.
Tip: For quick measurements, the probe can be brought into contact with the surface to be measured by using the
Coarse Adjuster Knob. Try not to move the Knob while scanning the surface. After scanning the surface use the
Knob to retract the probe. This will provide slightly reduced accuracy but greatly speed up measurements.
Starrett Altissimo Operation Manual Page 10 CAT 2000-24
Continuous Display and Scribing
Continuous Display: The Continuous Display Mode is normally used for Scribing. It can also be used to measure
features such as the centers of holes in sheet metal using a Conical Probe. Press the CONT Key to the right of the
Display to enter this mode.
The Display provides a reading of the current probe position. Lock the Probe Locking Knob and install the Scriber,
being careful to make the bottom of the scriber parallel to the Surface Plate. (See Figure 24) Using the Coarse
Adjustment Knob bring the Scriber lightly in contact with the Surface Plate. Press the F1 key to set the Active
Datum to 0 on the Surface Plate (or any other reference surface). (See Figure 25)
Move the Scriber close to the desired height using the Coarse Adjustment Knob. Pull out the Knob to engage the
Fine Adjustment Mechanism and adjust the scriber to the desired height. (See Figure 26) Tighten the Belt Locking
Knob and Scribe the Surface. (See Figure 27)
Note: If the tool beeps while scribing then make sure you have locked the Probe Locking Knob.

Care and Maintenance
Caution:
Use of this gage other than specified by the manufacturer is not recommended.
Use only Starrett replacement Battery Pack and Charger. Follow the charging conditions we specify.
Do not short-circuit the battery pack or disassemble the battery pack. This is dangerous and may cause heat
generation or fluid leakage.
Do not throw the battery into a fire or heat excessively.
Charge the batteries between 32 and 104°F (0 and 40°C). Charging the battery outside this range may cause the
batteries to leak, generate heat and shorten the service life of the batteries.
Store the batteries between 32 and 104° F (0 and 40°C). Storing the batteries outside this range may shorten the
service life of the batteries.
If the battery pack leaks fluids, changes shape, changes color or changes in any other form then discontinue use.
If the Battery Pack fails to charge in the prescribed period of time, do not recharge. The batteries could leak and
damage the gage. Replace the battery. Only use Starrett replacement battery pack.
If fluid from the battery comes in contact with the skin, wash the area immediately with clean water. Battery
fluid can injure the skin.
If fluid from the battery comes in contact with the eyes, wash them immediately with clean water (do not rub).
Battery fluid in the eyes can cause loss of sight.
Do not use this gage where it will be directly exposed to cutting fluids, water, dust, etc.
Do not use this gage where it will be exposed to direct sunlight, or drafts of hot or cold air.
Battery Charging - Battery charging automatically shuts off
after a predetermined time determined by the battery level. If
the Low Battery ICON is displayed this time will be fourteen
hours. The tool may be used while charging and may be left
connected to the charger if desired. (Figure 36) The Charge
circuit will maintain a charge after the battery is fully charged
without damaging the battery.
Installation Category - The Altissimo is an Installation
Category II device.
Important: If the Gage will not be used for an extended
period of time, remove the batteries. This will prevent the
possibility of a leaking battery damaging the case.
Replacing Batteries - The Altissimo uses advanced NiMH
Batteries, which should last many hundreds of recharge cycles.
If the batteries need to be replaced make sure all power is off
by unplugging the AC Adapter and switching the On/Off
switch to the 0 position. Remove Data Output Cable. Remove
the front cover of the electronics enclosure by unscrewing the
3 Phillips head screws located at the rear of the Display. (See
Figure 37)
Carefully remove the Front Cover and disconnect the Ground
Cable, Battery Cable and Display Cable from the
PC Board. (See Figure 38) Place the Display in a safe place.
The battery pack is mounted with Velcro, Carefully pull the
battery pack free and noting the orientation of the cable push
the new Battery Pack firmly in place Carefully reconnect the
Display Cable, Battery Cable and Ground Cable to the PC
Board. Screw the Front Cover back into place. Be careful not
to over tighten the screws.
Note: The Battery Charger must be inserted after replacing the
batteries in order to reinitialize the tool even if the battery pack
is fully charged.

E01 – This message usually results from an over speed condition. If this message appears on display, turn the power
off, wait 5 seconds and turn the power on again. Pressing the UNDO key and then the CLEAR Key may also clear
the error. If this fails to clear the error condition then it may be necessary to perform maintenance on the tool. See
Maintenance Section.
Probe Calibration
Deviation is high - If the Deviation is over .0002” (.004 mm), then check the tightness of the Probe Arm and Probe.
Check the cleanliness of the Probe Tip and Calibration Block. Make sure that the Probe and Belt Locks are fully
unlocked. Then recalibrate the Probe.
Inaccurate Measurements
Poor measurement repeatability - Check the tightness of the Probe Arm and Probe. Make sure that the Probe and
Belt Locks are fully unlocked. Then recalibrate the Probe and reestablish the Datum. Inaccurate Measurement Check to see that the proper Datum is selected.
Icons Flashing
If the Probe Icon in the upper left corner of the display is flashing the Probe needs to be calibrated. If the Datum
Icon in the upper left corner is flashing a Datum needs to be established.
Icons Light
If the word “FORCE” appears above the Probe Icon in the upper left corner of the display it indicates that the
Probing Force is set at a value other than the Calibrated Value. See Probe Force Setting in the Setup Mode Section.
If the battery symbol lights in the upper right corner the batteries should be recharged. See Battery Charging in Care
and Maintenance Section.
