Verify accuracy (pg. 3) on test disks at the beginning and the end
of each shift, or if the gage is dropped or suspected of giving
erroneous readings. Be sure to place the leg on the included
leveling plate when testing disks to maintain perpendicularity.
Introduction
Introduction
The Posi ector Barcol Hardness Impressor (BHI) is a hand-
held electronic instrument that measures the indentation hardness
of soft metals (aluminum, copper, brass), harder plastics and
fiberglass. It consists of a PosiTector body (Standard or
Advanced) and an interchangeable probe.
1.Power-up the Gage by pressing
the center navigation button.
Ensure the probe indentor is not in
contact with any surface.
2.To take a measurement:
a) Ensure the probe is
perpendicular to the surface being
tested. Press the probe down onto
the material to be measured until
the indentor foot is in full, flat
contact with the surface. HOLD
STEADY against the surface.
b) The Gage will emit a single BEEP and display a ▼ symbol
indicating a reading is being taken. The test timer will begin
counting down (see est ime, pg. 7). When the timer reaches
0s, the Gage will BEEP twice and display the measurement
value.
3.Lift the probe from the surface between readings.
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.

Calibration and Verification
Calibration and Verification
Two steps ensure best accuracy…
1.Calibration - typically performed by the manufacturer. All
probes include a Certificate of Calibration.
2.Verification of Accuracy - typically performed by the user on
known reference standards such as the included test disk.
Calibration
Calibration is the high-level, controlled and documented process
of measuring traceable calibration standards over the full
operating range of the probe, and verifying that the results are
within the stated accuracy of the probe. Calibrations are
performed by the manufacturer, their authorized agent, or by an
accredited calibration laboratory in a controlled environment using
a documented process.
Verification
Verification is an accuracy check performed by the user on known
reference standards. A successful verification requires the Gage
to read within the combined accuracy of the probe and the Test
Disks. Instrument operation may be verified with the included Test
Disks and Leveling Plate. Position the Leveling Plate under the
Leg and place the Test Disks on a flat, hard surface (as shown on
page 4). Take three to five readings on each disk. The
measurement points should be at least 6 mm (0.24”) apart. If the
average of those readings is outside the combined accuracy of the
Test Disk and gage, service may be required.
attach a different probe. It is not necessary to power-down the
Gage when switching probes.
The Posi ector gage body accepts a wide variety of probe types
including magnetic, eddy-current and ultrasonic coating thickness,
surface profile, environmental, hardness, salt contamination and
ultrasonic wall thickness probes. See www.defelsko.com/probes
Some causes for the gage to not read properly are the indentor
being damaged, incorrect pressure being applied to the test disk
or temperatures beyond normal conditions.

Verify accuracy at the beginning and the end of each work shift.
During the work shift, if the Gage is dropped or suspected of
giving erroneous readings, its accuracy should be re-verified.
Cal Settings Menu
Cal Settings Menu
The Posi ector BHI is factory calibrated and for most applications
no calibration adjustment is required. However, there may be times
when a zero, one or two point adjustment is necessary.
1. Select from the menu.
2. Press the button to select the number of readings
3. easure on the glass plate, ensuring that both the indentor
foot and leg are resting on the glass plate. After the last
measurement, the Gage will calculate a Zero which
represents the average of all the Zero readings taken.
Zero
Zeroing the Gage may be necessary after indentor replacement
or when the indentor is worn. For best accuracy, the Gage
should be zeroed on the included glass plate.

Adjusts the Gage to a known material hardness.
Step 1: Select 1 Pt Adjust from the Cal Settings menu.
Step 2: Press the button to select the number of readings to
be used to obtain an average, typically 3 to 10 readings. The
greater the variation between readings, the more readings should
be taken to obtain an average.
Step 3: Repeatedly measure the known hardness sample using
the on-screen green arrows as a guide. After the final reading,
the Gage will calculate and display an average measurement
value of all readings taken on the sample. If the expected
hardness value is not obtained (within tolerance), adjust the
displayed value up or down to the known hardness value
and press to save the value.

2 Pt Adjust
Adjusts the Gage within a range of two material hardnesses.
Step 1: Select 2 Pt Adjust from the Cal Settings menu.
Step 2: Press the button to select the number of readings to
be used to obtain an average, typically 3 to 10 readings. The
greater the variation between readings, the more readings
should be taken to obtain an average.
Step 3: Repeatedly measure the known hardness sample using
the on-screen green arrows as a guide. After the final reading,
the Gage will calculate and display an average measurement
value of all readings taken on the sample. If the expected
hardness value is not obtained (within tolerance), adjust the
displayed value up or down to the known hardness value
and press to save the value.
