[8] Judgement circuit
In withstanding voltage testing, this circuit compares the DC current measured in
the current detection circuit with the reference voltage, which corresponds to the
preset upper or lower reference. If a current exceeding the upper reference is
detected, the circuit determines that a withstanding voltage error has occurred and
cuts off the test voltage. In addition, if detected currents are below the lower refer-
ence, the circuit determines that the high-voltage test leadwire is disconnected or in
poor contact, and thus cuts off the test voltage.
[9] Control circuit
Controls the test voltage. This circuit also manages voltage measurement, current
measurement, judgement, and test time, in addition to conducting sequence control
on the CPU.
[10] POWER SUPPLY
Converts AC voltages from an AC line into DC voltages in order to supply them to
circuits

ASCII Code 20H to 7EH
These characters can be used for the title names in panel memory and program
memory and comments.
Turn the rotary knob counterclockwise to enter ASCII code [ ] (20H). Turn the
rotary knob clockwise to enter ASCII code [~] (7E).
• The tester does not accept [“] (22H), [‘] 27H, [,] (2CH), or [@] (40H).
