ON the 2182, enable SCAN (Note: Memory buffer annunciator comes on).
ON the 2400, enable SWEEP (Note: Arm annunciator comes on).
Press Trig on 2400.
After completion of the sweep, recall the data from the 2182 using the “TRACe” command.
To remove thermal EMFs from the readings, do the following math on the recalled data:
CH2 Rdg #1 = ( Buffer Rdg #1 - Buffer Rdg #5 ) / 2
CH2 Rdg #2 = ( Buffer Rdg #9 - Buffer Rdg #13 ) / 2
repeat.
CH1 Rdg_Pos #1 = ( Buffer Rdg #2 + Buffer Rdg #3 + Buffer Rdg #4 ) / 3
CH1 Rdg_Neg #1 = ( Buffer Rdg #6 + Buffer Rdg #7 + Buffer Rdg #8 ) / 3
CH1 Rdg#1 = ( CH1 Rdg_Pos #1 - CH1 Rdg_Neg #1 ) / 2
CH1 Rdg_Pos #2 = ( Buffer Rdg #10 + Buffer Rdg #11 + Buffer Rdg #12 ) / 3
CH1 Rdg_Neg #2 = ( Buffer Rdg #14 + Buffer Rdg #15 + Buffer Rdg #16 ) / 3
CH1 Rdg#2 = ( CH1 Rdg_Pos #2 - CH1 Rdg_Neg #2 ) / 2
repeat.
