1. For 10M
and 100M , V
measurement
is made on Input HI. Input Sense HI is
unused.
2. Default condition for 4-wire is
dmm.opendetector=dmm.ON
.
3. For
dmm.drycircuit=dmm.ON
, I
OPENLEAD
is disabled, but
print(dmm.opendetector)
returns 1.0.
4. Additional cable and Model 3700 card capacitance can increase settle
times, resulting in additional measurement uncertainty. Keithley Instruments
recommend the use of Teflon or other low-dielectric absorption wire
insulation for these measurements.
