1.1 Product Overview
1. Introduction
1.1 Product Overview
The 12706A test fixture is a sample box that connects to a measuring instrument such as
8340A, 8240 or 8252 to perform insulation resistance measurement and VSIM (voltage source
current measurement) of capacitors and other electrical components.
Features:
(1) A shielded and insulated structure is adopted, allowing stable measurement of low cur-
rent and high resistance.
(2) Voltage is applied by closing the cover and is shut off by opening the cover.
(3) A contact signal according to opening and closing of the cover controls the measuring
instrument.

1.2.1 Appearance Check
When receiving the 12706A, inspect it for any damage during transportation.
If there is any damage in appearance, please contact ADC Corporation or your sales represent-
ative.
Our address and phone number are listed at the end of this manual.
1.2.2 Operating Environment
(1) Use the 12706A in an area free from dust, corrosive gas and vibrations and away from di-
rect sunlight.
(2) The ambient temperature should be -20°C to + 80°C, the relative humidity should be 80%
or less.
(3) Storage
The storage temperature range is from -25°C to +80°C.
When not in use for a long time, cover the 12706A with a plastic sheet or put in a card-
board box, and store it in a low humidity area away from direct sunlight.
(4) Transportation
When transporting the 12706A, pack with the packaging materials used at delivery. If the
packaging materials have been lost, pack the 12706Aby using the following procedure:
a) Wrap the 12706Awith a plastic sheet.
b) Put it in a cardboard box (with thickness of 5 mm or more) and protect it with cu-
shioning materials.
c) Fix the outside with packing tape.

3. LID SIGNAL: contact output by opening and closing the cover
When the cover is closed, the terminals are short-circuited. When it is opened, the termin-
als are open-circuited.
Used to turn the applied voltage ON/OFF and to start measurement.
4. Test socket: socket to mount a sample
Voltage is applied to the V SOURCE and measurement is performed on the MEASURE.
Sample conditions: Axial lead part
Width: 23 mm or less, diameter: 14 mm or less
Lead diameter: 1.14mm or less
5. LID SIGNAL switch: switch of the LID SIGNAL [3]
6. Applied voltage switch: switch that shuts off the voltage applied to the V SOURCE ter-
minal of the test socket when the cover is opened.
The applied voltage switch has mechanical durability of 250,000 times operation. How-
ever, after it reaches the end of its service life, it will be always OFF regardless of open-
ing and closing of the cover. If a higher resistance or lower current value than an ex-
pected value is obtained in kwon measurement, the end of service life of the switch may
be reached.

Indicates high voltage danger. Printed for a terminal to which voltage higher than 1 kV is
input.
b. Warning symbol
Printed at a location where the operation manual needs to be referred to for protecting the
12706A from damage.

3.2.2 Connecting with the 8340A
This section describes the procedure of connecting the 12706A with the 8340A. See Figure
3-2.
Procedure:
(1) Attach the short bar to the input section of the 8340A.
(2) Connect the INPUT of the 8340Ato the INPUT of the 12706A by using the TRI-
AX-TRIAX cable (A01009 or A01239).
(3) Connect the V SOURCE HI of the 8340Ato the V SOURCE HI of the 12706Aby using
the banana-banana cable (A01240).
The V SOURCE LO does not need connecting.
(4) Connect the LID SIGNAL of the 8340A to the LID SIGNAL of the 12706A by using the
BNC-BNC cable (A01036-1500).
(The V SOURCE of he 8340A is turned ON/OFF by closing/opening the cover of the
12706A.)
The 8340Aoutputs applied voltage of maximum 1000 V. Perform connection or
measurement with great care.
Fix the short bar of the 8340A between the GND, GUARD and LO terminals.

3.2.3 Connecting with the 8240
This section describes the procedure of connecting the 12706A with the 8240. See Figure 3-3.
Procedure:
(1) Connect the INPUT of the 8240 to the INPUT of the 12706A by using the TRIAX-TRIAX
cable (A01009).
(2) Connect a voltage source such as the 6161 or 6144 to the V SOURCE (binding post) of
the 12706A by using the banana-banana cable (A01240).
1. The output voltage of the voltage source must not exceed the maximum input
voltage of the 8240.
For the maximum input voltage of the 8240, refer to the 8240 Operation Ma-
nual.
2. Be sure to turn ON the driving guard switch of the 8240
3. The maximum output voltage of the 6161 is 1100 V. Perform connection or
measurement with great care
