INTRODUCTION The SIKA UC mAV is a hand-held process calibrator (conforming toEC standards). It is more particularly intended for calibration and maintenance. It can measure and generate electrical quantities either on siteor in the laboratory. It fulfils voltage and current measuring and generation functions (DC or LF rampsignals) and a continuity test (on passive loop). Owing to its monitoring (regulation) mechanism in transmission mode, the instrument cannot take measurements and transmit simultaneously. APPLICATION Display of results in accordance with a linear conversion law or not. Generation of increments, single or cyclic ramp signals. Its utilisation is facilitated by a series of improvements Fast access to all the functions. Intuitive user interface. Graphic display of 160x160 pixels Connection by 4-mm safety sockets. Powered by 4 AA batteries or a rechargeable battery pack with fast internal charger (Option). The instrument is enclosed in an ABS casing with an elastomer sheath.
