Product Description TH0320 Reference Resistance Standard1. SummaryTH0320 is a series of precision standard resistors, suitable for measuring a wide range of precision current, it can also be applied for calibrating multifunction calibrators, high precision digital multi-meter, etc.2. FeaturesLong-term stability: 3 ppm/year (typical)Temperature coefficient: 0.2 ppm/°CNominal resistance: 1 Ω ~ 10 MΩ Low thermal potential terminal No oil or air baths required18°C ~ 28°C operating rangeSmall and rugged 3. ApplicationsCalibrate high precision resistance meter Calibrate standard resistance/precision resistance Establish high precision current measurement system☆ Calibrate Resistance MeterCalibrate two-wire (≥ 10 MΩ) or four-wire (≤ 1 MΩ) resistance meters as standard resistors. It can be used directly without placing in constant temperature oil tank or air tank. ☆Calibrate Standard/Precision Resistance Calibrate precision resistance with precision resistance bridge (such as TH0210). ☆ Establish High Precision DC Measurement SystemEstablish the current measurement system with I/I transfer standard and precision voltmeter.4.
