TOS6200A/6210 General 1-3
1.2 Introduction and Features
This tester is used to perform earth continuity tests required for class-I devices for
various safety standards, including the IEC, EN, UL, VDE, BS, JIS, and the Electri-
cal Appliance and Material Control Law of Japan.
The tester must be used under the following conditions:
• Making test current constant
The test current for earth continuity tests has been made constant. This eliminates
the need to alter the test current, even if the resistance of the DUT (device under
test) changes.
• Safety output voltage
The constant current/constant voltage circuit provides fast response, preventing
generation of excessive output voltage even when output is interrupted during test-
ing. The tester complies with the limitations on no-load output voltages (6 V or
less,
12 V or less, and so on) required by many safety standards.
