A
DANGER
To avoid any life-threatening electric shock accidents, ensure that the
following rules are observed.
･
The AC Withstanding 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.
NOTE
Chapter 3
Testing Method
This chapter describes the procedural flow for testing, making settings, and proper
testing procedure.
Read Chapter 2, "Testing Arrangements" and make the necessary arrangements for
testing.

keys to display the Optional function setting screen.
Setting the optional functions allows testing under various conditions.
For more information, see Chapter 4, "Optional Functions."
Note that the output waveform may be distorted when conducting an AC
withstand voltage test for a voltage-dependent device or object (e.g., ceramic
capacitor). Excessively large distortion may damage the device or tested object.
When the device or tested object is a capacitive load, resonance may occur (when
conducting an AC withstand voltage test) with the coil inductance of the output
high-voltage transformer, depending on the capacitance value. This condition may
generate several tens of volts at the voltage output terminal before the test is
started. If the
START
key is disabled, reset the output voltage knob to zero, then
set it back to the desired voltage after starting the test.
