160B - Option 3 Guarded Scanner
The 160B Opt.3 and 320B Opt.3 Low Thermal Guarded Scanners are designed to improve accuracy in high resistance measurements. Unguarded, the Data Proof scanners have leakages of about 1012 W which can cause errors of a few tenths of a ppm when measuring 1 MW. Guarding greatly reduces the errors allowing excellent accuracy up to the 1 0GW level.
