I 3201 TeraOhm 5 kV insulation tester is a portable instrument 

intended to measure insulation resistance through the use of high 
voltage DC test voltages up to 5 kV. The large LCD screen allows 
real-time R(t) graphs to be displayed.

Features

• Diagnostic tools - Polarization index (PI), Dielectric discharge 
  (DD) and Dielectric Absorption Ratio (DAR) with automated 
  resistance ranging. All parameters can be measured and 
  displayed in one single measurement.
• Step voltage test - Insulation resistance will be measured 
  at five different, equality sequenced test voltages for profound 
  insulation system diagnostics.
• R(t) graph - Real time resistance against time graph plotting 
  facility to graphically illustrate the response of a material to 
  an applied test voltage.
• High charging capacity - With 5 mA charging current insulation 
  systems up to 50 μF can be quickly charged and tested.
• High EM (noise) immunity - Built in noise rejection filters and 
  shielded test leads supplied in a standard set make the 
  instrument suitable for accurate insulation testing in environments 
  with high EM interferences like HV switchyards or similar.
• High protection level - CAT IV / 600 V overvoltage category 
  for industrial environments.
• Lightweight and user-friendly design - TeraOhm 5 kV Plus 
  is packed in a handy, rugged carrying case weighing only 3 kg.

Measuring Functions

• Automated testing - PI, DD, DAR calculations with automated 
  resistance ranging (AR). All data is displayed during one single measurement.
• Fault finding - Fully programmable step voltage and withstanding 
  voltage test functions to assist in diagnosing faults in insulation.
• R(t) graph - Real time resistance against time graph plotting 
  facility to graphically illustrate the response of a material to 
  an applied test voltage.
• Faster testing - High 5 mA charging current quickly charges 
  capacitive loads.
• Accurate - Selectable noise rejection filters (up to 5 mA) 
  and shielded cables as standard ensure accurate readings.
• Safe - High CAT IV, 600 V voltage protection
• Portable - Lightweight 3 kg design with carry handle and 
  shoulder strap.
