Measurement categories
To ensure safe operation of measuring instruments, IEC 61010 establishes
safety standards for various electrical environments, categorized as CAT II to
CAT IV, and called measurement categories.
Using a measuring instrument in an environment designated with a
WARNING
higher-numbered category than that for which the instrumen is rated
could result in a severe accident, and must be carefully avoided.
Never use a measuring instrument that lacks category labeling in a
CAT II to CAT IV measurement environment. Doing so could result in
a serious accident.

Notes on Use
Follow these precautions to ensure safe operation and to obtain the full
benefits of the various functions.
Observe the following precautions to avoid electric shock.
DANGE R
Do not remove the product's case. The internal components of the
product carry high voltages and may become very hot during
operation.
Do not touch the alligator clip while high voltage is being generated.
The vinyl sheath on the alligator clip of the 9615 H.V.TEST LEAD does
not have an insulation withstand voltage.
WARNING
CAUTION
To avoid electric shock, do not allow the product to get wet, and do
not use it when your hands are wet.
To avoid electric shock, connect the protective ground terminal to a
grounded conductor before making any other connections.
Before turning the product on, make sure the source voltage matches
that indicated on the product's power connector. Connection to an
improper supply voltage may damage the product and present an
electrical hazard.
Replace the fuse only with one of the specified characteristics and
voltage and current ratings. Using a non-specified fuse or shorting the
fuse holder may cause a life-threatening hazard.
Fuse type: 250VT1AL (
3173, 3173-01),
250VT0.5A L (
3173-02, 3173-03, 3173-04)
To avoid electrocution, turn off the power to all devices before
pluggingor unplugging any of the interface connectors.
To avoid damaging the power cord, grasp the plug, not the cord, when
unplugging the cord from the power outlet.
To avoid damaging the test leads, do not bend or pull the 9615 H.V. TEST
LEADs.
To avoid damage to the product, protect it from vibration or shock during
transport and handling, and be especially careful to avoid dropping.
Do not use the product near a device that generates a strong
electromagnetic field or electrostatic charge, as these may cause
erroneous measurements.
To avoid electric shock, do not exceed the lower of the ratings shown on
the instrument and test leads.
NOTE
______________________________________________________________________________________________

2.8 Startup Inspection
To ensure safe testing, check the following before starting operation:
(1) Breaking current
1
. Calculate the resistance based on the output-voltage set for withstand
voltage testing and the upper test value, and prepare a resistor
corresponding to the calculation result.
Note the power rating of the resistor.
(Output voltage / test upper limit (interrupting current) = resistance)
(The 2nd power of output voltage / resistance = power consumption <
powerratingofresistor)
A high-voltage resistor is recommended.
Example high-voltage resistor:
KOA Corp.'s GS Series High Voltage High Resistance Thick Film
Resistor
2
. Set an upper-limit value.
3
. Connect the resistor to the H.V. 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).
(2) 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.
(3) 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.

Chapter 3
Withstand Voltage
Testing Method
This chapter describes how to set withstand voltage test conditions and the
proper testing procedure.
Read Chapter 2, and make the necessary preparations for testing.
NOTE
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 adjustment knob
to zero
then set it back to the desired voltage after startingthe test.

output during output-voltage setting using the output-voltage adjustment knob.
Starting a test
｢READY状態｣
See Section 3.1.4 "Executing a Test"
When you press the START key, the DANGER lamp lights up and the test begins.
If the test timer is ON, the test timer LED starts blinking.
Determination
｢READY状態｣
See Section 3.2 "PASS or FAIL Determination"
Each test returns a PASS or FAIL judgment by comparing the currents measured during the set
test time with the set threshold. When a measurement equals or exceeds the threshold, the test
returns a FAIL judgment.
A PASS judgment is not returned if the test timer is OFF.

(red) test lead to the grounded side may lead to electric shock or
damage to the tester.
CAUTION
NOTE
For output, the unit uses a high-voltage transformer that boosts the power
voltage. If an unstable power voltage is used to operate the unit, the tested
object may be damaged by the distortion of the output-voltage waveform
and by the output of a voltage higher than the preset voltage.
If a capacity load is applied to the tested object, the output-voltage may
exceed the preset voltage, thereby damaging the equipment.
Continuous output of a high voltage may heat the bottom of the unit. Take
special care when handling the unit (e.g. transporting the unit).

6.1 Maintenance and Inspection
To ensure the safe operation of this unit, perform maintenance regularly.
・If the unit has been subject to moisture, or if oil and dust have accumulated in
the unit interior, the danger of electrical shock or fires resulting from the
deterioration of insulation increases greatly. If the unit is ever subject to
excessive moisture, oil, or dust, cease use immediately, and return the unit to us
for maintenance.
・Spare and replacement parts for this product are guaranteed to be available
only until 7 years after manufacture of this model is terminated.
・Replaceable Parts
Main parts to be replaced periodically, and their life times: (Useful life depends on
the operating environment and frequency of use. Operation cannot be guaranteed
beyo nd the follo w ing periods.)

_____________________________________________________________________________________________
If any of the following should occur, stop using the unit, disconnect the
power cord and 9615 H.V.TEST LEAD, and contact your dealer or HIOKI
representative.
・If you are certain that the unit is damaged.
・If the measurement you wish to perform is inoperative.
・If the unit was stored for a long period of time in high temperatures and
humidity, or other undesirable conditions.
・If the unit was damaged in transit.
6.2 Cleaning
To clean the product, wipe it gently with a soft cloth moistened with water
or mild detergent. Never use solvents such as benzene, alcohol, acetone,
ether, ketones, thinners or gasoline, as they can deform and discolor the
case.
