9.1 110
V
adapter
The AlphaPAT instrument allows measurements of 110 V appliances. When the 110 V
adapter is used only the following measurements can be performed:
earth bond resistance,
insulation resistance,
substitute leakage current, and
TRMS current.
Other measurements are prohibited in order to prevent damage of the tested appliance
if 230 V voltage is connected to it. The adapter is designed to prevent accidental
connection of 230 V supply voltage to the tested appliance. In substitute leakage current
measurement the displayed value is automatically calculated to 110 V when adapter is
connected to the instrument.
9.1.1 How to perform measurements by using 110 V adapter
In order to test 110 V appliance first connect 110 V adapter to the main test socket of
the instrument.
Connecting 110 V adapter to the instrument
If the 110 V adapter is connected to the test socket the following screen will be
displayed after starting earth bond resistance, insulation resistance or substitute
leakage current measurement:
110 V adapter warning screen 1
If you want to perform leakage current and power measurement, touch leakage current
measurement or polarity test, the following screen appears on the display for a few
seconds after the start:
