File name Guildline6664ADatasheet.pdf Model 6664B Low Thermal Quad Scanner Complements And Extends Guildline Bridges For Increased Flexibility G uildline 6664B Low Thermal Quad Scanner allows for the direct comparison of four terminal resistance standards, such as the Guildline 9330 and 9334A standard resistors. The scanner is designed to work with the Guildline Automatic Direct Current Comparator (DCC) Resistance / Temperature Bridges. Four terminal resistance comparisons can be made simply by selecting one device on the A-output lines and another on the B-output lines. All four connections for both resistors on the matrix are switched. All other connections remain floating. The 6664B performs switching for precision resistance measurements with less than 20 nanovolts of thermal offsets. Careful design in the use of latching relays requiring only a short pulse to actuate, eliminates self heating errors. The 6664B Low Thermal Quad Scanner allows for the direct comparison of four terminal resistance standards, such as the Guildline 9330 and 9334A standard resistors. 6664B Features Gold fingers on the relay armature make direct contact to hard gold pads on special circuit boards, and inputs are attached directly to the relay boards thereby reducing the number of > Thermoelectric Potentials: <20 nV connections.
