1.1 Product Overview
1. Introduction
1.1 Product Overview
The 12702A/B resistivity chamber is a shield box containing electrodes. It is used to measure
the volume resistivity and surface resistivity of sheet, filmy and platy samples together with a
voltage source such as the 8252 or 8240 digital electrometer, the 8340A digital ultra-high re-
sistance/micro current meter, or the 6161 DC current voltage source/monitor.
Features:
zThe pressure to the electrodes can be varied according to the sample used, allowing the
sample to be fixed firmly and reducing the measurement error.
zThe electrodes in the shielded box can be connected to a measuring instrument easily
with the connectors.
zVolume and surface resistivity measurements can be switched by pressing the button
switch.
zHigh-voltage application turns on and off according to opening and closing of the cover
of the shielded box for safety operation.
zThere are two types of resistivity chambers with electrodes of different size.
The 12702A complies with JIS-K6911, and the 12702B with JIS-K6723.
zThe thickness of a sample necessary for volume resistivity calculation can be measured
by using the dial gauge.
zA large sample can be measured without being cut.
1.2 Before Using the Product
When receiving the 12702A/B, inspect it for transport damage.
If there is any damage or defect, please contact ADC Corporation or your sales representative.
