Multi-function calibrator
1405, 1406,1407
burster
The model 1405 tests and calibrates quickly and easily displays, in control and process technology which is working on a resistance thermometer basis.
Description
The decade resistors are wire-wound resistors and consist of low-capacity and low-conductivity wire coiling made of ZERANIN®. An especially developed precision stepping switch with highquality contact materials and optimal brush construction guarantees very good reproducibility.
As regards accuracy, stability and reliability, the decades model 1406/07 are designed to meet high-standard requirements.
The design of the decade model 1405 enables its use not only as precision decade resistor but also precision calibrator for all standard commercial thermometers. Two fixed series resistors of 1 kΩ serve the simulation of Pt 1000 and Pt 2000 resistance thermometers. The four connection sockets provide the possibility of simple simulation of resistance thermometers operated in four-wire technology.
