b. Allow the readings to settle, then get the Series 2600 readings:
r0_hi, r0_lo = smua.contact.r()
c. Connect
a
50
Ω
resistor between the sense low and output low terminals, as shown in
. Also connect a second 50
Ω
resistor between the sense high and output
high terminals as shown in the figure.
d. Allow the readings to settle, then get the Series 2600 readings:
r50_hi, r50_lo = smua.contact.r()
e. Send the contact check low calibration command:
smua.contact.calibratelo(r0_lo, Z_actual,r50_lo,50_ohm_actual)
Where:
r0_lo
Series 2600 0
Ω
low measurement
Z_actual
actual zero value
r50_lo
Series 2600 50
Ω
low measurement
50_ohm_actual

Typical values:
smua.contact.calibratelo(r0_lo,0,r50_lo,50.15)
f.
(Where
r0_lo
and
r50_lo
are measurements taken in steps 2 and 4 above.)
g. Send the contact check high calibration command:
smua.contact.calibratehi(r0_hi, Z_actual,r50_hi,50_ohm_actual)
Where:
r0_hi
Series 2600 0
Ω
