August 2014 Revised edition 1 3159A985-01 14-08H
The Model 3159 Insulation/Withstanding HiTester is a hazardous instrume nt t hat generates high voltage.
For safe use, please read the “Introduct io n, ” “I nspection,” “Safety Notes,” and “Notes o n Use” in the 3159
Instruction Manual.
This document provides, as an example, a simple method for t est ing withstanding voltage of electrical
appliances by using the Model 3159 Insulation/Withstanding HiTester. For details on how to use the 3159,
refer to the 3159 Instruction Manual. (I nsul at ion resistance tests can also be performed with the 3159.)
Symbols and Notations Used in this Manual
···· Indicates that incorrect operation presents an extreme hazard that could result in serious
injury or death of the user.
···· Indicates that incorrect operation presents a possibility of injury to the user or damage to the
instrument.

The Model 3159 Insulation/Withstanding HiTester is a hazardous instrument that
generates high voltage. Please use due caution when handing the 3159. To prevent
electric shock, wear high-voltage rubber gloves and electric-proof rubber boots, and
put an electric-proof rubber sheet on the work surface.
Please read this manual thoroughly to ensure safe testing.

Do not perform tests in
locations that are:
• exposed to direct sunlight
• poorly ventilated
• subject to frequent mechanical vibrations
• near flammable objects

(2 ) Things to prepare:
1. Model 3159 Insulation/Withstanding HiTester
2. Electrical applianc e t o be tested
3. Rubber gloves for protection from high voltages (for safe testing)
4. Forms or a computer to record test results
5. Conductive wire (tinned wi r e or ot her non-i nsulated wire)
This wire is used to short-circuit the plug pins.
See figure below for details.
Short-circuit the plug pins with the conductive wire by following these steps.
1. Prepare a conductive wire .
2. Wind the wire tightly around the pl ug pins as shown
in the figure. Wind the wire aroun d t he pins 5 or 6 times.
Wind the wire t i ghtly to ensure s hor t -circuiting.
Wind the wire b e i ng careful not to b end the part of
the plug indicate d by (A).
3. Check:
Conduct a final check to ma ke sure that the wire is wound
<Example>

tightly around the plug pin s.
* Alternatively, use a recept acl e, w hich is custom-made for the test, w it h t he two leads short-circuited as
shown in the “Example test setup” abov e.
