• Reduced cycle time
A test current is a constant current value set within approximately 100 ms.
Earth continuity tests can be conducted even at 1-second intervals. This enables
the instrument to perform tests in production lines that require reduced cycle
times.
• Compact and lightweight
A new high-efficiency power supply (achieving a power conversion efficiency of
65%) and large output (TOS6200A: 150 VA, TOS6210: 220 VA) makes possible a
tester that is remarkably compact and lightweight, about half the size and weight
of our conventional testers.
• Excellent measurement accuracy
The tester is equipped with an ohmmeter of +/-(2% of r 0.003

) that cal-
culates resistance values based on measured current and voltage.
• Offset canceling function
The tester has an offset canceling function that cancels values for contact resis-
tance at alligator clip connections, the contact resistance of measuring leads in
measurements using two terminals, and other resistance components.
• Contact check function
The tester is provided with a contact check function that verifies the connection of
the DUT (by current detection) before initiating testing.
• Voltage judgment function
This function allows either a resistance value or a voltage drop value (voltage
between the SAMPLING terminals) to be selected as the reference value for judg-
ment criteria.
It also allows voltage drop value-based testing to be conducted, which is required
by safety standards such as UL 60950-1 and IEC 60950-1.
• Simple operations
Tester functions are fast and easily controlled, with an intuitive control method
that's easy to pick up, even for first-time users.
For example, test conditions are set simply by selecting an item displayed on the
LCD with the cursor keys and turning the rotary knob to set/select a value.
Any items you wish to set up can be assigned to the function keys.
