Typical static levels:
1000V acve dust aracon begins
3000V aracon of light materials e.g. 20µ lm
6000V aracon of heavier lm and papers & hairs on back of hand
move, danger level in many hazardous areas
10,000V lm wraps around rollers in coang & gravure prinng etc.
and severe dust aracon
The EX715 measures the surface voltage in V or kV. A common queson is
“What is the relaonship between surface voltage and eld strength?” The
relaonship is:
Surface voltage in V = eld strength in V/meter x distance from object in
meters
Range:
The EX715 has two ranges which are selected automacally:
• Up to ±20kV the resoluon is 10V
• From ±20kV to ±200kV the resoluon is 100V.
Battery Options
Important: The hazardous area cercaon of the EX715 is only valid if
the following baeries are used. The choice of baery will also dictate the
maximum ambient temperature in which the instrument can be used.
Duracell Industrial MN1604
Duracell Coppertop MN1604 gives the instrument a T4 rang with an
ambient temperature Ta ≤ +59ºC
Panasonic 6F22R gives the instrument a T5 rang with ambient
temperature Ta ≤ +40ºC]
