Calibration Standards

RS1 Resistance Calibration Standard


The RS1 is a cost efficient resistance standard in a sealed enclosure, entended for the calibration and verification of precision multimeters in laboratory, research, metrology and educational applications where a precise, yet economical resistance standard is needed.

It is available in four versions, calibrated to different accuracy levels, most compliant to ROHS. The resistors used are high accuracy, low drift metal film, wirewound or hermetic foil types, depending on the accuracy level desired. A PT100 temperature sensor is included for precise temperature measurement of the resistors.

The economy (-E) version uses metal film resistors and is focussed on lower accuracy applications such as e.g. 5.5 digit multimeters, educational purposes or similar. The advanced version (-A) and the precision version (-P) use wirewound and film resistors with different grade TCs, allowing for lower thermal and aging drift, and are e.g. intended for 6.5 / 7.5 digit DMMs. The precision (-H) version is based on hermetic, oil filled metal foil and film resistors with extremely low aging and temperature drift, for use as a secondary standard together with the most precise DMMs. The -E, -A and -P come with standard binding posts, the -H with gold plated Tellurium Copper posts for lowest EMF.

Calibration is based on highly precise DMMs and precision temperature-controlled resistance standards.  Calibration data  is shipped with every item.
Besides the standard versions, custom resistances can be made available, as well as versions with other connectors.

CS1 Capacitance Calibration Standard


The CS1 is a cost efficient coxial capacitance standard in a sealed enclosure, intended for the calibration of precision capacitanc / LCR meters in laboratory, research, metrology and educational applications where a precise yet economical capacitance standard is needed.
It is available in three  versions (-S, -P, -H), with a basic accuracy (deviation from nominal) of 5%, 1% or 0.1% (10pF higher), calibrated to an accuracy of 0.2%, 0.05% or 0.02%. The capacitors used are high accuracy, low drift types. Calibration is based on high precision capacitance bridges.  Calibration data is shipped with every item, specifying C and D values for each capacitance.
Besides the standard versions, custom versions are possible.

DVR1 Voltage Reference


The DVR1 is a very cost efficient, yet precision voltage reference assembly, capable of generating three precise and low-drift, buffered reference voltages of 10V (single voltage version) or 10V, 1V and 0,1V (triple voltage version). It incorporates a temperature-controlled oven to stabilize the output voltages, thus limiting the impact of ambient temperature fluctuations and is e.g. intended as an OEM product to be incorporated in equipment where precise reference voltages are needed. It may also be used to build up a lab voltage reference.
The use of burried zener diodes in hermetic package (LT1021) in combination with other low drift components and a precision temperature control circuitry is the prerequisit of precision voltage standards. This reference uses pre-aged components and a smart design, achieving high accuracy and low drift rates at a very attractive price/performance ratio. A PT100 temperature sensor enables monitoring of the internal reference temperature.
Every product is factory calibrated, traceable to national standards against a precision voltage standard (732A) with low uncertainty after a minimum of 500 hours of pre-aging for the references and an additional 100 hours for the complete unit. The calibration includes the adjustment of the 10V output and the precision measurement of the 1V and 0.1V output (for the tripple voltage version). The single output version supports 3 buffered outputs with 10V each. The unit is accompanied by factory calibration data.

Custom versions can be made available, please contact us.
