1-2 TOS5051A/5050A
1.1 Overview
The TOS5051A/5050A is a tester for carrying out withstanding voltage tests on elec-
tronic devices and electronic parts. The TOS5051A is capable of carrying out both
AC tests and DC tests; the TOS5050A is capable of carrying out AC tests.
This tester integrates new ideas and technologies with the conventional, consistent
philosophy of providing the highest safety, reliability, and operability to the operator.
• The tester is equipped with various safety features to protect the operator
from hazards. However, when the tester is in use, high voltage is applied
to the DUT. Inadvertently touching the DUT, test leads, probes, and output
terminals can cause electric shock.
• Be sure to provide full protective measures around the tester and DUT to
prevent electric shock--such as to enclose the test area with rope fences
to prevent access.
1.2 Features
1. Tests complying with major industrial standards
The tester can carry out withstanding (dielectric strength) tests on electronic
devices and electronic parts in compliance with JIS, UL, CSA, BS, and other
major electrical standards and ordinances.
2. Transformer capacity of 500 VA
The tester is equipped with a transformer, rated 500 VA.
3. Rational layouts of keys and switches
The keys have a slant-plane for easy viewing and convenient operation. The switch
for AC/DC select and test voltage range select and the control for test voltage
adjustment are installed concentrically, allowing you to operate them conveniently
with two concentric knobs. For the adjustment of the pass/fail-judgment limit cur-
rent and timer, dedicated increment/decrement keys are provided. These keys and
switches, together with the large display easy to view, are laid out rationally and
will assist you to conduct your tests accurately and ef
fi ciently.
4. A large color display
The tester has a large color vacuum fl uorescent display. The wide viewing angle
and high intensity indicates information in clearly. Various information including
test conditions, instrument status, measured values, and result of pass/fail judg-
ment are indicated using large letters and color assisting you to conduct your tests
accurately and ef
fi ciently.
