Page 6: Product Overview
1. Introduction 1.1 Product Overview The 12704A resistivity chamber is a shield box that is used to measure the volume resistivity and surface resistivity of sheet, cloth and filmy samples together with a digital electrometer, a digital ultra-high resistance/micro current meter, or other measuring instruments. -
Page 7: Before Using The Product
(3) Operating Environment Use the 12704A in an area free from dust, corrosive gas and vibrations and away from di- rect sunlight. The ambient temperature should be 0°C to + 60°C, the relative humidity should be 80% or less. - Page 8 The storage temperature range is from -5°C to +60°C. When not in use for a long time, in- sert the electrode protection sheet between the electrodes, cover the 12704A with a plastic sheet or put in a cardboard box, and store it in a low humidity area away from direct sun- light.

Main electrode plate Place the conductive rubber main electrode within the concave portion. Connects with the INPUT connector on the rear panel. Current flowing from the voltage application electrode to this electrode is measured. - Page 12 12704A Resistivity Chamber Operation Manual 2 .2 Electrode Section 10. Applied voltage switch Opening the cover will activate this switch to turn applied voltage OFF for safety. CAUTION The applied voltage switch has mechanical durability of 250,000 times operation. However, after it reaches the end of its service life, it will be always OFF regardless of opening and closing of the cover.

3. Measurement Method 3.1 Connecting to the Measuring Instruments This section describes the procedure of connecting the 12704A to measuring instruments. For the details of each instrument, refer to its operation manual. The following table shows connectable instruments and necessary cables and adapter. -
Page 17: Connecting With The 8340A
Connecting with the 8340A See Figure 3-1. (1) Connect the INPUT terminal of the 8340A to the INPUT terminal of the 12704A by us- ing the TRIAX-TRIAX cable (A01009). (2) Connect the V SOURCE terminal of the 8340A to the V SOURCE HI terminal of the 12704A by using the output cable (CC010005) and the banana adapter (A08531). -
Page 18: Connecting With The 8240
(1) Connect the INPUT terminal of the 8240 to the INPUT terminal of the 12704A by using the TRIAX-TRIAX cable (A01009). (2) Connect a voltage source such as the 6166 to the V SOURCE terminal of the 12704A by using the output cable (CC010005) and the banana adapter (A08531). -
