TOS6200

Earth Continuity Tester

Resistance value: 0.001 to 1.200Ω Test Current: 3 to 30 A AC Stores 100 test conditions in memory Incorporates conditions into program

Outline

The TOS6200 tester is designed to perform the earth continuity tests required for class-I devices by safety standards such as IEC, EN, VDE, BS, UL, JIS, and the Electrical Appliance and Material Safety Low (Japan). Equipped with a new high-efficiency power supply, it is compact and lightweight, about half the size and weight of our conventional products, while achieving a large output of 150 VA. Use of the constant current method eliminates the need to reset test currents even in the face of fluctuating resistance values for the device being tested. The test duration can also be set from 0.3 s, making the tester suitable for production line testing, which requires reduced cycle time. This tester is also designed for ease of use, featuring a large, easy-to-read display, memory capacity for storage of 100 types of test conditions, and incorporation of test conditions into programs to enable automatic testing. Standard GPIB and RS232C interfaces allow the user to use PCs or other devices to control test conditions such as test current, resistance value for judgement, and test duration, and enables read-back of measured values and test results. The tester is also provided with test leads as standard and provides high cost effectiveness.

Features

❏Making a test current constant

A test current for earth continuity testing has been made constant. Thus, the test current does not need to be reset even in the face of fluctuating resistance values for the device being tested.

❏High accuracy

The tester is equipped with an ammeter of ±(1% of reading + 0.2 A), a voltmeter of ±(1% of reading + 0.02 V), and an ohmmeter of ±(2% of reading + 0.003 Ω) that calculate resistance values based on measured current and voltage.

❏Offset canceling function

The tester is provided with an offset canceling function that cancels resistance values, such as the contact resistance at alligator-clip and the resistance of measurement leads when in two terminals testing method is used.

❏Provided with a contact check function

The tester has a contact check function that identifies the connection of the device being tested (by current detection) before testing.

❏Memo function

The tester has a memo function with a capacity of 60 characters of 20 digits by 3 lines. You can use it to save a serial number, calibration date, and/or comments.

❏Equipped with standard GPIB and RS-232C interfaces

The tester comes with standard GPIB and RS-232C interfaces, allowing external control of test conditions such as test current, judgement resistance value, and test duration. It also permits readback of measured values and test results.

*1:Time limitation with respect to output

The heat radiation capacity at the output block of the tester is designed to be half the rated output, accounting for size, weight, cost, and other factors. Always use the tester within the limitation values given below. Use of the tester beyond these limits will cause the temperature of the output block to rise excessively, potentially tripping the internal protection circuit. In this case, suspend testing for approximately 30 minutes, then press the STOP switch. When temperatures fall to normal levels, the tester will revert to ready status.
