Judgment Judgment procedure Display Buzzer External I/O
Upper fail If (measured value) > (upper reference
value)
is satisfied, the output is cut off, and
an upper-fail judgment is given. Judgment
is not performed during the judgment wait
time (delay time) beginning from the test
start.

On U_FAIL signal on
Lower fail If
(measured value) < (lower reference
value) is satisfied, the output is cut off, and
a lower-fail judgment is given. Judgment
not performed during the voltage rise time.

On L_FAIL signal on
Pass When (upper reference value) ≥ (measured
value) ≥ (lower reference value)
is satisfied
after the set time has elapsed, the output is
shut off, and a pass judgment is given.
Displayed on
the LCD
On PASS signal on
•The PASS signal is continuously output until the next test starts.
•The UPPER FAIL and LOWER FAIL signals are continuously output until the next
test starts.
•The fail and pass buzzer volume can be adjusted.
Upper-limit reference
value setting
0.010 mA to 100.0 mA (default setting: 0.011 mA)
Lower-limit reference
value setting
0.010 mA to 100 mA, off (default setting: Off, 0.010 mA)
Set resolution 0.001 mA (0.010 mA to 9.999 mA)
0.01 mA (10 mA to 99.99 mA)
Judgment accuracy For 1.000 mA or more:
±
(1.5% of setting)
For less than 1.000 mA:
±
(1.5% of s30 µA)
Automatic discharge
function
Operations Residual electric charge is discharged through the internal
circuit at the completion of a DC withstand voltage test.
(discharge resistance: 700 k
Ω
)
Start voltage Operations
Setting range
Default setting
The voltage at the start of a test can be set as a start
voltage.
0% to 99% of the test voltage (resolution: 1%)
0%
Limit voltage value Operations
Setting range
Default setting
The upper-limit reference value for the test voltage setting
can be set to prevent excessive voltage from being applied
to the test target due to operation errors, etc.
0.010 kV to 8.000 kV
8.000 kV
Output voltage monitoring
function
Operations The output is shut down and the test ends when the output
voltage exceeds
±
(5% of s50 V) after the voltage
rise time or the voltage deviates from the set test voltage
during the test and does not fall within
±
10 dgt of the set
voltage within 5 seconds.
Resistance value display Operations The resistance value, calculated by dividing the measured
voltage value by measured current value, of the test target
during a test is displayed.
Maximum current value
display
Operations The maximum value of the measured current value during a
test can be displayed.
