Transmille smart calibration multimeters of 8 1 / 2 and 7 1 / 2 digits

Instrumentos de Medida, S.L. presents the 8000 series of multimeters Transmille formed by the 8081 and 8071 models that offer outstanding precision and linearity along with ease of use.

The heart of any instrument is its precision analog design. The experience and knowledge gained by Transmille after 10 years of manufacturing multi gauges 3000 Series have helped develop these new multimeters.
The choice of components is crucial in the design. The 8000 series multimeters are equipped with precision resistors with temperature coefficients of less than 1 ppm C, analog amplifiers chopper stabilized operational art and very low leakage switches.
A zener reference to provide a stabilized temperature stability of 1 ppm / year. The printed circuit design is critical and is necessary to eliminate the effect of the emf thermal and leakage to ensure functionality of 8? digits. To provide stable readings in noisy environments as cycles are synchronized with feeding.
To complement the analog design has been built into the 8000 series using multiprocessor computing capacity of today's processors. Low-level processors are responsible for measuring ranges, the control of A / D converters and other functions while a 64-bit processor is responsible for handling the data. Just a few years was necessary circuitry offering several cards with a capacity of processing and a much lower reliability.
The 8000 series multimeters complement multi gauges and patterns of the 3000 series calibrators and electrical safety in the 3200 series. This range of equipment in conjunction with the calibration software provides a complete solution to modern calibration laboratory.
Unique measurement capabilities unavailable from other multimeters:

- Programmable switching terminals:
Connections to control remotely from the meter front panel or from PC switching action between benchmarks and measuring devices.
- Intelligent function relation of reference:
This mode of operation to connect a known pattern to the rear terminals and the device to be measured from the front connectors for measurements of relationship. The multimeter automatically switches between the two devices offering the value of the unknown value of pattern known whose value has been introduced previously.
- Temperature Measurements (8081):
The model 8081 allows accurate measurements of temperature platinum thermometers. Includes advanced modes of storage of the coefficients for the probes.
- Measures pressure (8081):
The 8081 model is compatible with the range of pressure sensors in the 3000 series for direct measurements of pressure.
- Measures low currents (0.1 pA to 10μA):
The 8081 can measure continuous currents below 10nA with a resolution of 0.1 pA using a low noise BNC terminal dedicated. This entrance is very low impedance approaching an ideal ammeter and providing integrated functionality of an electrometer on the multimeter.
- Measures resistance of high value. (8081):
The 8081 can measure resistances up to 1 TW using the BNC input low current in conjunction with an internal voltage source of up to 200 V.
