Low Thermal Guarded Scanner

160B Opt. 5 & 320B Opt. 5 - Data Proof (dp)

Data Proof’s Low Thermal Guarded Scanners are designed to improve accuracy in high resistance measurements. Unguarded, the Data Proof scanners have leakages of about 1.5 x 1012 Ω which can cause errors of a few tenths of a ppm when measuring 1 MΩ. Guarding reduces the errors allowing excellent accuracy up to the 1 GΩ level.
