Introduction

The PosiTector Surface Profile Gage (SPG) is a hand-held
electronic instrument that measures the surface profile (peak-to­valley height) of blasted steel, textured coatings and concrete
profile. It consists of a PosiTector body (Standard or Advanced) and
probe.

Quick Start

Press the button to power up the Gage. To conserve battery
life, the gage will automatically go to sleep after 5 minutes of
inactivity. While in Sleep Mode, the gage powers up significantly
faster— convenient when moving between parts or locations. The
gage will completely power off after 4 hours of inactivity.
Alternatively, select Power Off from the main menu. All settings
are retained.

1. Remove the protective rubber cap from probe.

2. Power-up Gage by pressing the center navigation button.

3. Verify Gage accuracy (pg. 3).

4. Place the probe FLAT on the surface to be measured such

that the tip of the probe reaches into the bottom of a profile
valley. HOLD STEADY. The Gage will BEEP twice and
display the measurement.

5. Lift the probe from the surface between measurements.

Menu Operation

To access the Menu, power-up the gage, then press the center
navigation button . Either the keypad or touch screen can be
used to navigate the menu. If desired, touch screen functionality
can be disabled within the Setup menu (See Touch, pg. 5).

Select a menu option by touching it, or use the and but­tons to highlight the desired option and press to select it.

On menus longer than one page, the current page number is
displayed below the menu name. Navigate between pages using

when the first menu item is selected, or when the last
menu item is selected. If using touch, navigate between pages
by touching or , or by swiping up or down.

indicates that a sub-menu exists for the
Menu option. Select the option to display its
sub menu.

Probes

When powered-up, the PosiTector automatically
determines which probe is attached and does a self­check.

To disconnect a probe from a body, slide the plastic
probe connector horizontally (in the direction of the
arrow) away from the body. Reverse these steps to
attach a different probe. It is not necessary to power­down the Gage when switching probes.

PosiTector SPG and SPG S probes include a 60˚ (ASTM D 4417
B) or 30˚ (Australian Standard AS 3894.5) angle tip (50 µm/2 mil
radius) with a measurement range of 0 to 500 µm (20 mils).

PosiTector SPG OS probes have the same specifications as the
PosiTector SPG probes above but feature a V-groove sleeve ideal

for measuring flat or convex surfaces such as tanks and pipes.
PosiTector SPG CS probes measure the profile of textured

coatings up to 1500 µm (60 mils) with a 500 µm (20 mil) radius 60˚
angle tip.

PosiTector SPG TS probes measure concrete surface profile up
to 6 mm (250 mils) with a 500 µm (20 mil) radius 60˚ angle tip.

Additionally, the PosiTector body accepts a wide variety of
probe types including magnetic, eddy current, and ultrasonic
coating thickness, surface profile, hardness, salt contamination,
and ultrasonic wall thickness probes.

Calibration & Verification of Accuracy

Calibration

Instrument calibration is typically performed by the manufacturer.
All probes include a Certificate of Calibration.

Verification of Accuracy

Instrument accuracy is verified using the included metal shim and
glass zero plate. Ensure that the glass plate and shim are clean
and dirt free before use.

Place the plate onto a stable, flat surface. Take several
measurements. If the average is greater than ±5 µm (0.2 mil),
Zero (pg. 4) the Gage.

Next, place the metal shim over the glass plate and measure,
ensuring the probe needle touches the glass plate in the area
between the shim’s “legs”. The average of several measurements
should be within the combined tolerances of both the Gage and

the shim.

If not, see Returning for Service (pg. 11).

Zero

The PosiTector SPG has only one adjustment point at zero.
The zero point can be set using one of two methods.
Both methods are found under the Zero menu option:

Glass Plate Zero

Zeroing on the included glass plate is the preferred method for
best accuracy:

1. Select from the menu.

2. Press the button to select the number of readings

to be used to obtain an average, typically 3.

3. Repeatedly measure the glass plate. After the last
measurement, the Gage will calculate a zero which
represents the average of all the zero readings taken.

Factory Zero

If a glass plate or suitable smooth, hard surface is not available,
the factory zero setting can be restored:

1. Select from the menu.

2. Press the button to select Reset (below) and press the

button. The factory calibration icon will appear on the

display.

NOTE:

particularly after a probe tip exchange. For best accuracy, the
Gage should be zeroed on the included glass plate.

Set Clock

All measurements are date and time stamped (24-hour format)
when stored into memory. It is therefore important to set the
correct date and time. Use the and buttons to select a
value, and the and buttons to adjust it. The current date
and time setting can also be viewed at the top of the main menu.

Battery Type

Selects the type of batteries used in the Gage from a choice of
“Alkaline”, “Lithium” or “NiMH” (nickel-metal hydride rechargeable).
The battery state indicator symbol is calibrated for the selected
battery type. No damage will occur if the battery type used in the
Gage does not match the selected battery type.

Select batches to flag them for synchronization to the PosiTector
App. Sync Batches is useful when connecting a new device to a
gage with pre-existing batches, since only batches created while
Bluetooth Smart is enabled are automatically selected.

Selected batches are synchronized when the next reading is
taken in a batch flagged for synchronization, or when the Sync
Batches option is selected at the bottom of the list of selected

Returning for Service

Before returning the Gage for service…

1. Install new or newly recharged batteries in the proper
alignment as shown within battery compartment.

2. Examine the probe tip for dirt or damage. The probe tip should
move up and down freely. The plate surrounding the
probe tip should be smooth and free from burrs and foreign
material.

3. Perform a Hard Reset (pg. 5).

4. Place the metal shim over the glass plate and attempt a

measurement.

5. If issue is not resolved, Update (pg. 10) your PosiTector
gage body and re-attempt measurements.
