Specifications
Performance summary
Specifications describe the instrument's warranted performance over the temperature range 0° to 55 °C (except where noted.) Supplemental characteristics
are intended to provide information useful in applying the instrument by giving typical, but non-warranted, performance parameters. These are denoted as
"typical," "nominal," or "approximately." Where specifications are subject to minimization with the error correction routine, corrected limits are given unless
noted. (The error correction routine is a built-in routine using the CAL OUTPUT signal and pressing SHIFT W then SHIFT X. The message CORR'D appears
in the CRT display when the correction is being applied.)
