22. Specifications
22.1
Withstanding voltage test section
22.1.1 Test voltage
(1) Applied voltage
0~5kV AC
(2) Output capacity
500VA (5kV, 100mA) at the power source voltage 100V AC.
For the output current 50mA or higher, 30 min. or less continuously.
(3) Wave shape
Shape of commercial power source.
(4) Voltage fluctuation rate
15% or less
(with the rated power source voltage and at no load
⇒
max. load)
(5) Voltage output system
Zero-cross throw switch.
(6) Setting of output voltage Setting by motor slider.
(7) Setting accuracy of slider
±
30V, except for the error due to voltage fluctuation.
22.1.2 Voltage measurement
(1) Rectification system
Effective average rectification value display.
(2) Analog
Scale
0~5kV AC
Accuracy
±
5% of F.S.
(3) Digital
Measuring range
0.00~6.00kV AC, 3 digits green LED,
character height 10mm.
Accuracy
±
1.5% of F.S (F.S 5kV)
Voltage display
Voltage applied to the high voltage terminal
is displayed during the test. Voltage at the
judgement is retained at the finish of the test.
22.1.3 Current measurement
(1) Rectification system
Effective average rectification value display.
(2) Measuring range
0.01~199.9mA (2 ranges, joint change-over with high limit value)
(3) Display
Digital display in 3 1/2 digits, green LED, character height 10mm.
(4) Resolution
0.01mA (0.1~9.9mA)
Note: ( ) shows high limit set value.

(5) Measuring accuracy
±
(5%+20
μ
A) of high limit set value.
(6) Current display
Leak current value is displayed during the test.
Leak current value at the judgement is retained at the finish of the
test (at NG of withstanding voltage or at I-W, W test mode).
22.1.4 Judgement of test result
(1) Judgement system
High limit
Analog comparator (for short-circuit detection,
with the set value internally fixed)
High limit, low limit
Digital comparator.
(2) Adjustable range
High limit 0.1~110.0mA(Low limit +1 digit or more) Resolution 0.1mA.
Low limit 0.1~109.0mA(High limit –1 digit or less) Resolution 0.1mA
Note
:
Low limit setting can be ON/OFF (Judgement function: OFF,
[LOW SET] LED is turned off.)
(3) Judgement condition

(W-GOOD LED lit up, output ON)
High limit value

Leak current ……………………….
NG
(W-HIGH LED lit up, output ON)
Low limit value
≧
Leak current ……………………….

(W-LOW LED lit up, output ON)
Note:
Output time of GOOD judgement can be switched to
continuous or 0.2s.
For the AC withstanding voltage testers, the leak current due to the
capacity distribution in the high voltage cable, jig and so on can cause
the judgement error.
Please determine the judgement criterion value, taking this leak current
into account.
The following values are the referential values on condition that the
wiring is made, keeping the distance between HIGH voltage side cable
(red) and LOW voltage side cable(black) of the attached high voltage
cable (5880-25-020).
