28. Call niDMM_ConfigureMeasurement with the following
parameters:
• Function =
NIDMM_VAL_2_WIRE_RES
• Range = 10e3
• Resolution = 0.01
29. Call niDMM_ConfigureMultiPoint with the following parameters:
• Trigger Count =
1
• Sample Count = 4
• Sample Trigger = NIDMM_VAL_IMMEDIATE
• Sample Interval = –1
30. Call niDMM_ReadMultiPoint with the following parameters:
• Maximum Time =
NIDMM_VAL_TIME_LIMIT_AUTO
• Array Size = 4
Average the results by summing the returned reading array of the
function and dividing by the returned actual number of points.
Store the result as the 10 kΩ range offset.
31. Call
niDMM_ConfigureMeasurement with the following
parameters:
• Function =
NIDMM_VAL_2_WIRE_RES
• Range = 1e3
• Resolution = 1e–3
32. Call niDMM_ConfigureMultiPoint with the following parameters:
• Trigger Count =
1
• Sample Count = 4
• Sample Trigger = NIDMM_VAL_IMMEDIATE
• Sample Interval = –1
33. Call niDMM_ReadMultiPoint with the following parameters:
• Maximum Time =
NIDMM_VAL_TIME_LIMIT_AUTO
• Array Size = 4
Average the results by summing the returned reading array of the
function and dividing by the returned actual number of points.
Store the result as the 1 kΩ range offset.
34. Call
niDMM_ConfigureMeasurement with the following
parameters:
• Function =
NIDMM_VAL_2_WIRE_RES
• Range = 100
• Resolution = 100e–6
