Item Description Panel operation
Voltage Sets the test voltage. You cannot specify a voltage that is greater than or equal to the limit voltage. SET key
0.00 kV to 5.50 kV Setting Rotary knob
Limit Voltage Sets the limit voltage. This prevents an unnecessarily high voltage from being applied to the DUT
because of incorrect operations of the TOS5300 Series.
LIMIT (SHIFT+SET) key
0.00 kV to 5.50 kV Setting Rotary knob
Sets the upper limit that is used in judgments. If a current that is greater than or equal to the upper
limit is measured, a U-FAIL judgment occurs.
UPR/ LWR key
0.01 mA to 110 mA Setting Rotary knob
Sets the lower limit that is used in judgments. While LOWER is on, if a current that is less than or
equal to the lower limit is measured, an L-FAIL judgment occurs.
UPR/ LWR key
0.01 mA to 110 mA Setting Rotary knob
OFF The lower limit is not used in judgments.
ON/ OFF (SHIFT+UPR/
LWR) key
Sets the test time. The test time begins when the voltage rise time elapses. The test time begins
when the voltage rise time elapses.
TEST key
0.1 s to 999 s When the specified time elapses, the test ends. Rotary knob
OFF
The set test time is ignored. A PASS judgment is not performed.
Press STOP to stop testing.

Start Voltage Sets the start voltage to 50 % of the test voltage. MORE key
50 % The start voltage is set to 50 % of the test voltage.
