DANGER
To avoid any life-threatening electric shock accidents, ensure that the
following rules are observed.
･
The AC Withstanding Voltage HiTester is a dangerous product which
discharges high voltages. To prevent getting electrocuted, always
wear high-voltage protective rubber gloves when carrying out any
operation.
･
Be careful when using the product and ensure that you do not touch
this product, any tested object that is connected or any H.V. TEST
LEAD, etc.
･
Make sure that no high voltage is being applied to the output,
confirm the following items, and connect the H.V. TEST LEAD.
(1) The analog voltmeter reads 0 kV.
(2) The DANGER lamp is OFF.
(3) The TEST lamp is OFF.
･
In the TEST state, never touch the output-voltage terminal, H.V. TEST
LEAD, or tested object.
･
Even following a test, there may be a residual voltage at the output
terminal. Therefore, before touching the output-voltage terminal, H.V.
TEST LEAD, or tested object, make sure that no high voltage is being
applied between the output terminals.
NOTE
･
If the HIGH and LOW voltage output terminals short-circuit or a dielectric
breakdown occurs in the tested object during the test, noise will be generated and
such noise may lead to a malfunction of this unit or of a nearby electronic device.
If this problem occurs, connect a ferrite core or a resistor to the H. V. TEST
LEAD (high voltage side).
When using a resistor, choose one appropriate for the power rating and withstand
voltage. Also, be alert to any drop in test voltage.
Beware of electric shock when connecting the resistor.
･
Do not the test lead and the EXT/IO cable arranged closely to each other.
Doing so may lead to a ma l functio n of the external control due to a noise.
Additionally, if the test lead touches to other metallic parts, it may cause an
increase in leakage current.
Prevent the test lead from coming into contact with other parts as much as possible .
(1) Make sure the analog voltmeter is at 0 kV and the DANGER lamp is OFF, and
the TEST lamp is OFF.
(2) Connect the LOW terminal probe to the tested object. Fasten the probe securely
to prevent it from loosening during a t est.
(3) Following the procedure described above, connect the HIGH terminal probe to
the tested object.

2.10 Startup Inspection
To ensure safe testing, check the following before starting operation:
Breaking current
(1) Calculate the resistance based on the output voltage to be set and the upper level
value, and then provide a resistor suitable for the resistance.
(Output voltage÷Upper-level value (Breaking current) = Resistance)
A high-voltage resistor with a power rating larger than the power calculated
from the output voltage and resistance is recommended.
2
÷
((Output voltage)
Ex.)
For the case that the output voltage is 2 kV and the upper level value is 4 mA,
Resistance value=2 kV／4mA＝0.5 M
Rated power=(2 kV)
the 16 W resistor ((Rated power) x 2)) is recommendable to leave a margin.

(2) Set an upper-level value.
(3) Connect the resistor to the test lead.
(4) Increase the output voltage beyond the set value, and make sure the current is
cut off (i.e., make sure the unit is in the FAIL state).
Analog voltmeter
(1) Before turning on the power, make sure the analog voltmeter is at 0 kV.
(2) If the voltage reading is not at zero, adjust the value to zero using a slotted
screwdriver.
Inter-lock
If the Inter-lock function is set, make sure the Inter-lock function works properly
before starting operation.
Key inspection
(1) Turn off the power, and unplug the power cord from the power outlet.
(2) For both the START and STOP keys on the front panel of the unit, press the
center of the key, and make sure you feel it click. The click is less noticeable
when the edges of the keys are pressed.
* Clicking
When a key is pressed slowly, there is a moment of slight resistance and a
feeling that the key cannot be pressed any further. When the key is pressed
further after this point, a clicking sensation can be felt.
(3) If you do not feel a click, the key may be broken.
