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.

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.

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 8340A to the INPUT of the 12706A by using the TRI-

AX-TRIAX cable (A01009 or A01239). (3) Connect the V SOURCE HI of the 8340A to the V SOURCE HI of the 12706A by 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 8340A outputs 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.

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

3.3 Measurement

3.3 Measurement Procedure:

(1) Attach a sample, referring to Section 3.1.

(2) Connect the 12706A with a measuring instrument, referring to Section 3.2.

(3) For the 8340A or 8252, set to voltage source current measurement (VSIM) or voltage source resistance measurement (VSRM). For the 8240, set to DC current measurement.

(4) Closing the cover of the 12706A will turn on the applied voltage switch, allowing mea-surement.

1. 12706A adopts a safety design. However, be careful when using high voltage as applied voltage.

2. Do not give vibrations to the 12706A or connected measuring instrument and cables during low current or high resistance measurement, otherwise measured values will vary.
