Simple and safe operation. The Amblyonix 2000 series of Kilovolt Meters combine high-accuracy with rugged construction. Each model comes with a durable aluminum case for transportation or shipment. Measuring circuits are designed with precision amplifiers and a dual-slope integrating processor. Simple and safe operation using front panel switches to select voltage ranges and AC/DC functions. High input impedance reduces test current and power consumption. Features Modern high-performance operational amplifiers Dual-slope A/D sampling Units are extremely stable and linear Safely switch between ranges and AC/DC functions Extremely portable > Specifications Ranges: 0-5.0 kV AC/DC and 0-50 kV AC/DC Accuracy (percent of full scale): 1% AC, 0.5% DC Resolution: 0.001 kV (low range) Operating Environment: 32 to 104°F and to 85% RH Interconnecting Cable Length: 9 9 Power supply: Standard 9 V Battery Input impedance: 600 M Ohm Weight: 13.25 lbs. > Each Unit Includes A rugged aluminum case, manual, interconnecting cable, ground cable, and NIST Traceable Certificate of Calibration.
