Data sheet - Calibration Resistor Modelserie 1240 - 1

Calibration Resistor te ertifica With C ISO 9000 ing to accord Application The 0.02 class calibration resistors excel in their modern design and small mechanical dimensions. Their ruggedness also ensures a long life. Calibration resistors of the 1240 series are used wherever very constant operating standards are required. Typical main areas of application therefore include: ► When normal resistors prove to be too large scale ► For test and calibration of resistance measurement devices ► For tests on electrical temperature measuring equipment ► For laboratory setup of a Wheatstone bridge ► As shunt resistor for accurate current measurement ► As part of standard equipment in research laboratories ► For a large part of measurements in calibration laboratory A test certificate according to ISO 9000 with detailed technical data is included in the scope of delivery of these high-quality calibration resistors.

All data sheets at www.burster.com Range 10 µΩ ... 100 kΩ Low capacitance and low inductance design Suitable for direct current and technical frequencies High stability < ± 0.01 % over years DAkkS Calibration Certificate The calibration laboratory D-K-15141-01-00 at burster praezisionsmesstechnik is supervised by DAkkS (Deutsche Akkreditierungsstelle GmbH) according to ISO 17025. It can prove its status by a certificate and is authorized to issue calibration certificates with the DAkkS logo and with the DKD logo (Deutscher Kalibrierdienst). These calibration certificates are internationally approved by multilateral contracts. Manufacturer Calibration Certificate Please refer to DAkkS Calibration Certificate but with reduced accuracy. The calibration resistors can also be delivered with a manufacturer calibration certificate. It confirms the traceability of the used secondary voltage and resistance standards to the national standards according to DIN ISO 9000ff and is guaranteed by our certified calibration laboratory (D-K-15141-01-00). burster praezisionsmesstechnik gmbh & co kg Germany www.burster.com Talstr. 1-5 .
