１．Preface
We would like to thank you for your purchase of our MODEL 8507. For safety and proper use of this product,
please carefully read this operation manual before the use.
【Feature / Characteristics】
8507 is a withstand voltage tester with maximum output 1000V and output capacity 10VA.
The setting of upper and lower limit leakage current and the function of timer enable the test result more
accurately.
8 sets of re-writable and readable memories of test conditions can be stored.
START/STOP operation can be done by external control using remote I/O connector.
Depending on measuring conditions, the test result like judgment can be obtained by open collector.
! Caution
● To avoid break-down, malfunction or deterioration of life time,
do not use this product in such places where:
◆ Exposed to rain, water drops or direct sunlight.
◆ High temperature or humidity, heavy dust or corrosive gas.
◆ Affected by external noise, radio waves or static electricity.
◆ where there is constant vibration or shock.
● Do not open the case or modify the main body.
1.1 Preparations prior to use
● Unpacking
When the tester is delivered, please check whether it conforms to the required specifications and has not
been damaged in transit. If there is any damage on the tester or it does no work in conformity with the
specifications, please inform us of the model and product name.
● Storage
In case of storing the tester for a long time, store it at the place of low humidity and where it is not
exposed to the direct sunlight.
1.2 Confirmation prior to use
● Power supply
Use the tester with the power source voltage within 90 to 250VAC and the frequency 50/60Hz.
When connecting the power supply cable, confirm that the power supply switch is turned OFF
● Power supply cable
The plug of power supply cable connected to the tester is for 100VAC use. When the tester is used with
200VAC, replace the plug with appropriate one for 200VAC use. Please connect the power supply cable to
the power supply connector on the rear panel of the tester. The plug of power supply cable has 3 pins and
the round shape pin in the center is for grounding.

MODEL 8507 - 2 -
1.3 Warning and caution during measurement
Electric shock accident or malfunction
! Warning
● Check and confirm the cable condition and metal portion of the wire before
use. There is a danger of electric shock if the measuring cable is broken or the
metal portion of the wire is exposed. If some damage is found, stop using it
immediately and replace the specified new one.
● In order to prevent the electric shock accident or the failure of this unit, do not
apply voltage to the measurement terminal.
● In order to prevent the failure, conduct the measurement after turning off the
power related to the measurement.
● A high voltage is passed through the measuring cable. Never touch the tip of
the measuring cable to avoid the electric shock.
Connection of the control cable and communication cable
! Caution
● Use the specified cable size to connect the control terminal.
● Make sure that communication cable and control cable are connected surely. If
the connection is not undertaken correctly, it may cause of the failure to satisfy
specification or malfunction.
● Power supply must be turned off on each device before connection of
communication cable and control cable. Failure to turn of the electric power
cause the electric shock or malfunction.
Other caution
! Caution
If power supply is done by UPS（Uninterruptible power supply device) or DC-AC
inverter, do not use rectangular wave or pseudo rectangular wave output of
UPS or DC-AC inverter. If used, this may cause the malfunction of the
instrument.

２．Preparation before use
2.１ Connection of power code
１ Make sure that the power switch POWER of this tester is turned off.
２ Connect the power cord to the inlet for the power supply of the rear panel.
The plug of the power cord that comes with this tester is for AC100V. If it exceeds AC125V, use the
power cord suitable for the rating. 200V type power cord with a plug attached (European 2-pole with
earth model name 5880-23-030) is optional.
３ Power cord plug (3P) is connected to the earthed outlet.
The plug of the power cord is 3- pin and the round shaped pin of the center is the earthing.
! Warning
Use supply voltage AC100 to AC240V (AC90 to 250V) and power frequency
50/60Hz. Besides, when you connect the power cord, make sure that the power
switch is turned off. Beyond this range could lead to the failure and incomplete
operation of the tester.
2.２ Connection of protective earth terminal
Earth the protective earth terminal ⑨ to the ground using the supplied earthing wire. When the earthing
is imperfect or when the output is short circuited to the ground or power line, the case of the tester is
highly charged and it is dangerous to touch it. Besides, when using the tester, be sure to check that the
earthing wire is not disconnected.
! Warning
If the earthing is imperfect, there is a risk of an electric shock.
2.３ Connection of the external control equipment
External control equipment can be connected to the remote I/O connector ⑩
Ref. to “6. External control” for information about connection method.

MODEL 8507 - 4 -
2.４ Connection of high voltage cable
During the test, the high voltage output terminal is charged to a high voltage. Connect the supplied high
voltage cable with the HIGH VOLTAGE terminal and LOW terminal. For high voltage cable, use the
supplied cable or cable adaptable for the voltage used.
! Warning
Make sure to confirm the power off before connecting the high voltage cable.
There is a risk of an electrical shock.
! Warning
When the low voltage side cable is disconnected, the whole tested equipment
gets charged with high voltage and there is a risk of an electric shock.
2.５ Power on and off
After purchasing for the first time when POWER switch⑮ is on, the test begins and due to interlock
function, the state becomes PROTECTION state. Connect the supplied remote I/O connector.
Use the supplied remote I/O connector only after the PROTECT state is released easily.
If you do the actual test, use the interlock function for the safety.
To guard the test area against the electric shock, use the interlock function like cut-off etc.
when opening the door or cover.
１ Make sure that the power cord, connection cables etc. are connected properly.
２ Press “－” side of POWER switch ⑬of rear panel to turn it on.
３ After turning on the power switch, all lights on display are on for few seconds (lamp test).
However, TEST VOLTAGE and CURRENT/RESISTANCE display firm version.
After a few seconds, the display would be of test mode when the previous power was turned off.
４ Press “○” side of the POWER switch of the rear panel to turn it off.
