TEST & MEASUREMENT

MICROCAL To keep your test and process equipment accurately calibrated for ISO 9000 compliance

PerformanceThe palm-top indicator-simulator series MicroCal are multifunction instruments designed to check and calibrate your test and process equipment. MicroCal calibrators meet, in a modern and practical way, the everyday needs of Quality and Maintenance instrumentation engineers, both in laboratory and fleld work. Accurate, compact, rugged, easy to use; the ideal solution for measuring and simulating: millivolts, volts, milliamperes, ohms, thermocouples and resistance thermometers. Eurotron palm-top calibrators have been developed using the most advanced microprocessor technology to grant high accuracy on extended ranges and a powerful operating flexibility. The modular firmware includes the algorithms for thermocouples and resistance thermometers in accordance with IEC, DIN and JIS standards. Both IPTS68 and ITS90 temperature scale are memory stored and can be selected using the keyboard. A unique internal automatic Rj compensation system providing the accurate input and output readings in a temperature range from -5C to +50C. Further, external compensation is available with temperature programmable from -50C to +100C. The simulationmeasurement of resistance and temperature with resistance thermometers uses a special proprietary active circuit (Eurotron Patent 206327). The calibrators are able to source a single step value; to program up to 7 simulation programs using up to 60 values; and to source programmable loops (start, step, end values and time), using menu-driven procedures. The instruments can mathematically filter unstable input signals, convert linear signals in technical units and linearize quadratic signals. Selection of the operating function is made using a rugged membrane keyboard which assures up to one million operations per key. MicroCal use two special thick film membrane slidewires to set the simulated signal value. Measured or simulated value is indicated on a high quality alphanumeric LCD dot matrix display which provides good contrast even in poor lighting conditions. The instrument is powered by four Ni-MH rechargeable batteries; an external battery charger is supplied as standard accessory. Quality System Research, development, production, inspection and certification activities are defined by methods and procedures of the Eurotron Quality System. Eurotron Quality System has been inspected and certified for compliance to lSO 9001 by Gastec, a Dutch notified body. Five models MicroCal palm-top series include 5 different calibrators to select the instrument more suitable for each specificy laboratory and/or field applications. High accuracy and stability are the key and important technical specifications. MicroCal 1+ MAV: One and two channels mA (active and passive loop) and up to 10V process signal calibrator MicroCal 1+: 13 thermocouples, 3 Rtds, mV up to 1 Volt, mA and ohms universal calibrator MicroCal 1 IS: EEx ia IIC T6 Intrisically safe multifunction calibrator MicroCal 2+: Two channel multifunction calibrator for simultaneous measurement and simulation for TRX calibration. MicroCal 10+: 0.01% accuracy, multifunction calibrator. Display & Keyboard The high contrast alphanumeric LCD display with dot matrix (7x5 dots per character - 16 characters) allows easy reading even in poor light conditions. Simultaneous indication of the measured or simulated value, engineering unit, type of sensor or signal, temperature scale and Rj mode. MicroCal 2+, the 2 channels calibrator, has a 2 line back lighted LCD display for simultaneous reading of input and output signals. A metal-click tactile polycarbonate membrane keyboard ( MicroCal 1+ MAV, MicroCal 2+ and MicroCal 10+), with a working life of one million operations per key, seal the internal electronics from the surrounding environment. Contact closure of the membrane keys is acknowledged, as a coded signal, directly by the microprocessor. Two thick film membrane slidewires (patent pending) allows the quick and an easy setting of the simulation value. Source & Measure thermoelectric signals Each instrument, through a menu-driven procedure, allows measurement or simulation of mV, mA, or any normalised IEC, DIN and JIS thermoelectric sensor
