The PosiTector 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.
This Quick Guide summarizes the basic functions of the gage.

The PosiTector BHI powers-up when the center navigation
button is pressed. To preserve battery life, the Gage powers-down
after approximately 5 minutes of no activity. All settings are retained.
1. Power-up the Gage by pressing the center navigation
Ensure the probe indentor (pg. 2) 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 Test Time, 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.
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.
IMPORTANT:
when they become worn or visibly pitted.
