JCI 140 Field Mill Static Monitor
The JCI 140 is a compact instrument for easy detection and measurement of static electricity and 
滚球体育for assessment of risks in practical situations.


General Description
The JCI 140 Static Monitor is a compact, easy to use instrument for direct non-contact 
measurement of surface voltage. It is available in 3 options: F – Fast Response, X – Extended 
Range & XF - Fast Response Extended Range. From a distance of 100 mm the 3½ digit liquid 
crystal display indicates surface voltage to an accuracy of 1 Volt. This makes it particularly easy 
to find even low levels of static charge and to make measurements with confidence.
As a field mill instrument there is no need to switch-on in a static free environment, no need 
for measurements to be made within a limited time and no need to worry about the influence 
of air ionisation –  which are all concerns with simple ‘induction probe‘ type instruments. The 
novel mode of operation of the JCI 140, with no earthing of the rotor (the instrument must still 
be earthed), provides quiet, stable operation with fast response and long operational life.
The  JCI 148  and JCI 146  are compatible modular voltmeter adapters for use with the JCI 140. 
Both instruments allow direct measurement of voltages on live conductors using a probe. The 
JCI 140, when used with the JCI 148, can measure voltages up to 20kV dc and the JCI 146 
can measure voltages up to 60kV dc. The very high input resistance of these systems eliminates 
the loading effects suffered by many high voltage voltmeters and high voltage adapters for 
multimeters. The JCI 147  is a compatible modular  Faraday Pail  adaptor for use with the 
JCI 140. It allows direct measurement of charge (in nano Coulombs) on items placed in the 
Faraday Pail.

JCI 148 Electrostatic Voltmeter Adapter
Compatible with  JCI 140  Static Monitor
The JCI 148 can be used for accurate measurement of voltages with negligible current 
drain.


General Description
The JCI 148 Electrostatic Voltmeter comprises a shielding enclosure in which an electrode, 
connected to the input, is supported by high quality insulation in a well-defined and stable 
geometric arrangement relative to the sensing aperture of a  JCI 140  Static Monitor. 
The geometry is such that the numbers shown on the display correspond directly to the 
applied voltage input in kV.  
The attraction of an electrostatic voltmeter based on the JCI 140 Static Monitor is the 
near zero current drain (limited only by insulation leakage not less than 10
14
 Ohms at up 
to 20kV), the high sensitivity (1V resolution in 2kV range), the low internal capacitance 
滚球体育(about 7pF), high input time constant and the linearity of response.

Specification
Ranges:        2kV & 20kV full scale. 1V and 10V resolution 
Accuracy and linearity :         Within ±2% FSD on JCI 140 display and analogue output signal
