Huace Huace103 electrometer
One, overview:
This instrument is a new type of electrostatic voltmeterHuace103 type electrostatic improvement based on the original BD 21 type electrostatic voltage meter on the meter with BD compared to 21 due to the use of integrated circuit segment amplifying technology and high performance in low voltage such as 200mV and 2V, which is far less than the drift of KEITLEY 616 and not 617 electrometer preheat start can measure 24 hour shift is less than 0.5%, it is very sensitive to electrostatic very high input impedance meter
Two, the characteristics and scope of application:
1, has a very high input impedance
2, has a wide measuring range.
3, in line with national standards of conductive and anti electrostatic plastic electrical resistivity measurement
4, in line with national standards GB12014-89 anti-static overalls or Japanese JIST8118-1983
5, anti - static work clothing requirements
With static performance test method of national standard GB/T 12703-91 requirements of textile material
Three, technical indicators:
1 the measurement range of DC 200mV 200V, the use of pressure resistance and capacitance divider can expand the measuring range
2 accuracy 0.5 of reading 2 words
The input impedance of the 3 11014 100T
4 drift time drift 24 hours less than 0.5%; the temperature drift is less than 0.05%/
5 220VAC 50HZ 10W power supply
6 quality 2KG
The 7 dimensions of 220mm 230mm 80mm
Four, the measurement principle:
The instrument adopts high performance integrated circuit high input impedance input input impedance is greater than 11014, close to 11015 general purpose working voltage in the range of less than 15V 15V and the instruments used in a wide range of power supply by the suspension technology makes the electrometer voltage range 275V voltage range up to DC 200V.
Five, method of use:
1, the measurement of cable and instrument input end connected with power line
2, open the power supply monitor should be red
3, will switch to the input circuit the display of 000 adjustments to zero
4, will switch to the appropriate range is selected according to the height of the measured voltage measurements can be measured
In six, the matters needing attention
1, do not allow the measuring voltage range beyond the range of the input stage otherwise it may damage the instrument beyond the range should be greater although the decline in performance of the instrument protection but over voltage can make the electrometer beyond the scope display 1
2, avoid objects and human body with high voltage on the input contact or close in order to avoid electrostatic discharge damage inside the meter high input impedance electrometer amplifier
3, the machine has high pressure not dangerous just open the instrument in order to avoid electric shock
4, the use of high input cable should be shielded cable insulating polyethylene, otherwise it will affect the input impedance
