ADR Series
ＤＥＣＡＤＥＳＴＡＮＤＡＲＤ ＲＥＳＩＳＴＯＲ (ＤｉｇｉｔａｌＴｙｐｅ)The ADR Digital Type equipped with a CPU is easy
to set a desired resistance value either by hand inlocal mode or by personal Computer in remote mode.
The ADR Digital Type originally holds data memory
such as specific ohmic values corresponding totemperatures in Pt100 resistance thermometer sothat data inputting jobs can be eliminated, resulting
in time saving for measuring operation. It is constructedwith ultra-precision metal foil resistors which are
manufactured by Alpha Electronics Corp. and whichhave been established as the best precision resistive
component in the world market for the very low
temperature coefficient and the excellent long -term
Stability of resistance. In order to itself fromenvironmental noise, it is properly dressed in double
electrical shielding.

ADR Series
ＤＥＣＡＤＥＳＴＡＮＤＡＲＤＲＥＳＩＳＴＯＲ（６ＤｉａｌＴｙｐｅ）
The ultra -Precision resistor, the rotary Switch, theoutput terminal and the double shield construction
feature the ADR 6 Dial Type with 61/2 digit readings.
Resistor used in the ADR 6 Dial Type are ultra Precision metal foil resistors manufactured by AlphaElectronics Corp., assuring high stability to time andhave very low contact resistance as three Clip-typedcontacts are connected in parallel.The three contacts
assure higher reliability mechanically.Output terminals
have little thermal EMF, using rectangular wires oflow thermal resistance material in a wel l- designed
circuit configuration. Double shielded construction
inhibits interference of environmental noise.
