The IR meter consists of the compact mainframe 4000 having two slots and the modular units 40051, 40052, 40053 and 40054. It configures up to 4 channels by combining the modular units.

In recent years, it is necessary to improve the takt time of manufacturing and inspection in production lines of parts or components. Consequently, measuring instruments used in these production lines require higher measuring speed, multiple channles. space saving and other optimal functions.

This IR meter can satisfy such needs by adopting the modular system.


4000  2-slot modular instrument

The 4000 is a 2-slot modular instrument of 2U half-size mainframe to which 2 units of 0.7U half-size modules can be installed.
It is equipped with various interfaces; USB, GPIB, LAN and RS232, making it possible to build inspection systems for R&D or production lines of electronics components by connecting to a personal computer or programmable controller.
In addition, the 4-channel handler interface allows you timing control with automatic machines, and device selection according to measurement and judgment results by the modules. In inspection lines, you can easily perform system setup or maintenance of modules that are mounted on system racks without removal such as module replacement, operation check via USB on the front panel.
Moreover, by using the digital I/O of 8 bits having a 5 V/200 mA power supply, easy relay control and signal generation are available. 

40051/40052/40053/40054/40057  IR meter units


The 40051, 40052, 40053, 40054 and 40057 IR meter units are to be mounted into the 2-slots modular instrument 4000. The 1-channel 40051, 40053 and 40057 and 2-channel 40052 and 40054 are integration-method IR meters, suitable for current measurement of high-capacity samples such as capacitors.
The current measurement range is from 10 fA to 3.2 mA, and the voltage source range is up to ±200 V/3.2 mA for the 40051 and 40052, up to +300 V or -100 V/3.2A for the 40053 and 40054, or up to +2000 V/0.8 mA or ±200 V/3.2 mA for the 40057. The resistance measurement range is between 312 Ω to 3×1017 Ω.
In addition, it has a contact check function (C.CHK) by capacity (C) measurement to judge the contact status of highresistance samples.
Moreover, the handler interface signals to be controlled from automatic machines in production lines are directly output to the rear connectors on the 4000.
