Electronic Specialties Self Calibrating True RMS DMM ESI485

Patented Self Calibration Function maintains accuracy over the long term and in varying temperatures Training DVD featuring Dan Sullivan with 10 videos covering each major DMM function – includes multimeter testing tips and advice True RMS accuracy, Auto-Ranging & CATIII safety rating 6,000 count back-lit LCD display and built-in temperature F/C Zippered carrying case included for safe storageThis self-calibrating DMM leverages new technology through the use of high stability, low temperature coefficient resistors in the resistors network. Once the self-calibration function is turned on, the multimeter will automatically compare the standard resistor with other resistors in the resistors network, measure and store the actual and accurate values. The accuracy can endure for extended periods in a wide range of temperature environments. A self-calibration multimeter is an undoubtedly more accurate, more reliable measurement tool. User simply presses the button to CALIBRATE when they feel it is necessary. Patented Self Calibration Function maintains accuracy over the long term and in varying temperatures
