  • 50 ppm absolute accuracy
  • 1 m Ω resoluƟ on
  • No “zero” resistance; direct seƫ ng
  • Highest performance RTD simulator avail able
  • Highest accuracy, highest stability, lowest TC
  • wide range - 10 Ω to 1111.110 Ω Model RTD-Z-6-.001 High Accuracy RTD Simulator SPECIFICATIONS The RTD Series Precision RTD (Resistance Temperature Detector) Simulator provides a very broad- range of absolute resistance values. The RTD simulator effectively re- places an RTD to test, analyze, and calibrate RTD measuring systems. The RTD Series is ideal where ap pli- ca Ɵ ons of Re sis tance Tem per a ture De tec tor (RTD) sim u la Ɵ on re quire exact low value re sis tance without “zero” and con tact re sis tance eff ects.
  • Virtually independent of contact resistance variaƟ on
  • Ideal for DIN PT-100, PT-100 ANSI, PT-50 and NI-120 systems Model RTD-Z-6-.001 RTD-X-6-.001 RTD-Z-6-.01 RTD-X-6-.01 Minimum resistance (Ω) 10.000 10.000 10.00 10.00 Max i mum resistance (Ω) 1,111.110 1,111.110 11,111.10 11,111.10 Resolution (mΩ) 111 0 1 0 Number of decades 6666 Absolute accuracy (ppm) 50 100 50 100 Tempco max. (ppm/°C) 5555 Tempco typical (ppm/°C) 3333 Stability (ppm/24hrs) 2222 Stability (ppm/year) 10 10 10 10 Dimensions Switch Setting: The 10 Ω switch has two stops at positions 1 and 10. Absolute accuracy, without zero subtraction, is accomplished by having a minimum settable resistance, which includes all contact and wiring resistances. Absolute accuracy applies for every setting. See table above for the minimum settable resistance for any model. Minimum settable resistance is implemented by a mechanical stop in one of the decades. Maximum Power for rated accuracy: 100 mW or 100 mA for 10.000 to 10.999 Ω; 100 mW per step for the highest decade in use for 11 Ω and over. Terminals: Four, 5-way, gold-plated, tellurium-copper binding posts with low thermal emf and low resistance, for four-terminal Kelvin measurements, plus one binding post connected to case for shielding. Connection to Terminals: 2 terminal devices: use H and L CURRENT terminals 3 terminal devices: use H CURRENT - L CURRENT and G terminals; 4 terminal devices: use all CURRENT and SENSE terminals. (Note: Ground Strap is the only connection between CURRENT and SENSE terminals.) Switch type: Multiple solid silver contacts; dust-tight diallyl-phthalate body. To allow continuous rotation, a blank position is added on all decades except the 10 Ω decade. Resistor type : Wirewound , hermetically sealed , low-inductance Maximum Current: 200 mA. Breakdown Voltage: 1000 V. Environmental conditions: Operating temperature: 0ºC to 55ºC . Storage temperature: -40ºC to 70ºC . Humidity: <80% RH.
