B. Allow the readings to settle, then get the Series 2600B readings:
r0_hi, r0_lo = smua.contact.r()
C. Characterize both 50
Ω
resistors using the resistance function of the digital multimeter.
D. As illustrated in the following figure:
•
Characterize both 50 Ω resistors using the resistance function of the digital multimeter.
•
Connect a 50 Ω resistor between the SENSE LO and LO terminals.
•
Connect the second 50 Ω resistor between the SENSE HI and HI terminals.

E. Allow the readings to settle, then get the Series 2600B readings:
r50_hi, r50_lo = smua.contact.r()
F. Send the contact check low calibration adjustment command:
smua.contact.calibratelo(
r0_lo, Z_actual, r50_lo, 50_ohm_actual
)
Where:
r0_lo
= Series 2600B 0
Ω
low measurement
Z_actual
= Actual zero value; the resistance of the short between the SENSE LO and LO
terminals
r50_lo
= Series 2600B 50
Ω
low measurement
50_ohm_actual
= Actual 50
Ω
resistor value; the actual value of the resistor between the SENSE
LO and LO terminals
Typical values:
smua.contact.calibratelo(r0_lo, 0, r50_lo, 50.15)
Where
r0_lo
is the same value as measured in step B, and
r50_lo
is the same value as
measured in step E.
