Introduction
1.1
Normal Use
The resistance decade 1427 is a precise programmable resistance decade for a range from 1.000 00
Ω
to
1 200 000
Ω
.
It is designed for checking parameters of resistance meters, regulators and process meters, which use
external resistance sensors for the measurement of non-electric magnitudes. The preset resistance value
is created by a appropriate combination of physical resistors.
The Decade is equipped with a build-in function for the direct simulation of the most frequent temperature
sensors, Pt and Ni.
Relays with a low thermal voltage and stable foil resistors with low temperature coefficient are used as
main parts of the decade.
Set values are displayed on the front panel display. The 1427 is a sophisticated instrument with its own
re-calibration procedure. This procedure allows the correction of any deviation in resistance without
mechanical adjusting.
The Instrument is especially designed for automatic testing procedures. A RS232 interface (optional
IEEE488 bus) is used for linking the decade and a computer.
