VH102K 10K resistor calibrated with TCR 0.61ppm/°C

Description: For sale is a single Vishay VH102K hermetically sealed resistor with a nominal value of 10 KOhms. The resistor is old one, but not used. The date code is from 2006 year. The calibration is not ISO 17025 accredited.I can not issue an invoice, because I'm individual, not a company. The resistor is calibrated against Agilent 3458A DMM at 23.038°C average (0.06°C peak to peak) with the following settings:- 4 wire connection using PTFE cables- Enabled offset compensation- Delay 0.5sec.- NPLC = 100Before the resistors calibration, the DMM is adjusted with metrology traceable 10K reference resistor which have relative expanded uncertainty of 0.41ppm. The resistor is calibrated in the Bulgarian Institute of Metrology in June 2022. The copy of the certificate is given in the pictures. The calibrated value of the resistor is 10000.4515 Ohms with relative expanded uncertainty of 3.88 ppm using coverage factor k = 2 (95% confidence). The full calibration report is given in the pictures. The measurement was done between 25 March and 6 April 2024. According datasheet of the Vishay, the shelf life is 5ppm for 1 year, 10ppm for 3 years. The total measured TCR is 6.1 ppm for the 18-28°C range or 0.61ppm/°C, using temperature controlled box with TEC module and temperature stability +/-0.06°C. Approximated linear function for calculation of the resistance in the range of 18-28°C is given in the picture.The error of approximation is +/- 0.16ppm. The expanded uncertainty is calculated based on uncertainty budget which includes:- Repeatability based on 11 samples (Type A).- Reproducibility based on 11 measurements during period for 2 weeks (Type A). - Agilent 3458A 24h transfer uncertainty for the respective resistance ranges (Type B). This includes the relative expanded uncertainty, drift and TCR of the reference resistor. - Agilent 3458A temperature drift value when ACAL is used (Type B). An option for re-calibration service exists for 50 EUR in the EU only, excluding the shipping cost. For calibration of the resistor, when it is bought outside the EU, please contact me. The resistor is soldered on a PCB which can be attached to multimeter by two ways:1. Directly with a banana plugs when the PCB is detached from the aluminium box. This avoids measurements errors when cables are used like capacitance and leakage.2. With cables via the binding posts which are not part of this set. The PCB can be attached directly with banana plugs to the following models of DMMs :HP/Agilent/Keysight 34401A, 34410A, 34411A, 34460A, 34461A, 34465A, 34470A, 3458A, 3455A 3456AKeithley 2000, 2001, 2002Wavetek 1271, 1281Siglent SDM3065X, SDM3055X, SDM3045XRigol DM3058E, DM3058, DM3068All Prema DMM which have 4W resistance measurements. Note that due Prema DMM case (4001, 5000/1, 6000/1), the PCB plugs can not fully insert into the binding posts and should be rotated to 180° - plugs for the source inputs will become sense and via versa.
