STATIC METER

The 715 Static Meter has been
developed to enable industrial
engineers to investigate static
electricity problems.

Its accuracy, stability and ease
of use make it the leading
instrument in its class.

>t The 715 measures static electricity
on the surface of a material, at a
distance of 100mm.
>t The meter can show where and
how the static is generated, its
magnitude and its polarity.
>t The 715 monitors the effectiveness
of the action taken to solve the
problem. If the solution involves
static control equipment, the 715
shows its most effective position.
>t The 715 allows the engineer to set
standards to avoid future problems.
These can range from an acceptable
level of charge in materials, to
charge levels in products being
produced by the process.
>t The 715 has two ranges selected
automatically. The high range
measures up to 200kV with a
resolution of 100V. The low range
measures up to 20kV with a
resolution of 10V.
> t There is a “hold” facility to freeze
the reading on the display.

How the 715 works:
Static electricity is a potential problem in many industrial areas. It slows production,
reduces product quality, attracts contaminants and gives shocks to operators.
The 715 enables the engineer to investigate these static electricity problems
scientifically. Static is a coulombic charge - forming current when it moves, but
difficult to measure when it is not moving. The 715 measures the surface voltage
using Q=CV : the 100mm reading distance is the constant capacitance which allows
the voltage to vary directly with the charge.
