TERA Ohmmeter 600
SYSTEMPROF. DR. ING. HANSKLEINW CHTER
The TERA Ohmmeter TOM600 operates with theVoltage-Current-Measurement.
Highresistances upto2x1012Ohm(2TERAOhm)can bemeasuredwith avoltageof
100 voltsand aprecision of5%
Aspeculiarity,theambienttemperature and thehumiditywillbemeasured andstoredto
every measured resistance value
