Adjustment using the built-in Voltage Calculator
The
Voltage Calculator
simplifies the task of setting the correct
test voltage for a particular coating system. It prompts the user to
enter the coating thickness on the part to be tested and the
standard the user is conforming to, and automatically calculates
the correct test voltage.
1. With the detector powered
ON
and in
Standby Mode
,
press to open the menu then select the
Voltage
Calculator
icon from the Menu
2. The gage will display a list of common international standards
3. Use the or button to highlight the desired standard
4. Press the button to select the desired standard
5. Depending on the selected standard, a
Units Selection
menu
may appear. If prompted, select the desired coating thickness
measurement units.
6. A thickness adjustment screen is now shown. Using the or
button, adjust the coating thickness to the maximum thickness
of the coating to be inspected.
Depending on the standard chosen, the range of
selectable coating thicknesses may be limited.
NOTE:
7. Press the button to select the thickness. The
PosiTest HHD
will now calculate the test voltage based on the standard and
units selected.

The following standards are available when using the Voltage
Calculator:
AS 3894.1:F1, F2, F3, F4
ASTM D4787, D5162, G62
ISO 29601
NACE SP0274, SP0188, SP0490
Voltage adjustments will be retained when the
PosiTest
HHD
is powered OFF. Perform a
RESET
(pg. 11) to return to the
default voltage setting (1kV).
