Features
Desktop 4 1/2  LED digital display, AC AC 220V power supply, continuous long-term work. Input impedance can be 1GΩ- 10GΩ, the standard is 1GΩ.
Introduction to the instrument
● Basic table using the United States imported high-precision CMOS A / D converter, six 0.5-inch red LED digital display (four and a half 19999 plus polarity), the measurement rate of 2.5 times / second, automatic temperature compensation, input polarity automatic identification , Over-range flashing alarm.
● On the basis of the basic table, through the increase of high-voltage high-impedance input circuit, special low bias current precision instrumentation amplifier, a variety of waveforms high precision real RMS / DC voltage (TRMS / DC) converter circuit, HV), AC high-voltage (AC-HV), AC-DC hybrid high voltage (\'AC + DC\'-HV). (* Note: do not TRMS / DC converter, that is, DC high-impedance high-pressure table)
● Measurement range according to the requirements of production, usually: 0 - 2KV or 0 - 20KV. Input impedance can be done 1GΩ- 10GΩ, the standard is 1GΩ, the decimal point by the range setting, the corresponding invalid zero automatically cleared, for example:
(A) range 2KV four decimal point, resolution 0.1V full scale 1.9999KV
(B) range 20KV three decimal point, resolution 1V full scale 19.999KV *
  * Note 1: Common measurement range: 0 - 20KV, Rin = 1GΩ, can meet most of the use.
  * Note 2: 20KV file in continuous measurement, for the safe and reliable, should control the input voltage in the 0 - 15KV.
  * Note 3: measurement to be connected to the local (Lo), the instrument is high pressure, negative high pressure can be measured. High pressure measurement to regulate the operation, pay attention to safety.
High-voltage high-resistance input circuit: the use of anti-moisture, long-term stability of the professional high resistance resistors, precision resistors, high voltage insulation materials, made through a special structure process, stable performance.
● Accuracy: more than 1% (DC table up to 0.5%); overload tolerance: 2KV (5KV), 20KV (25KV) * peak.
● window with double filter, display bright and clear, soft and natural, natural light can also be observed.
● independent development and design, the use of double-sided PCB board, plug and patch mixed manufacturing process, high-quality components, stable and reliable, inexpensive.
● Standard industrial desktop instrument case (195 * 70 * 175mm), AC 220V power supply. Suitable for micropower (close to static) voltage measurement. For example: leakage voltage test, negative ion generator voltage test and so on.
  Note: According to the user requirements of the technical parameters, display, function and other customized to meet the actual needs.
