DMMOpenCalACCaps
SMU2060
SMU2064
Description
Calibrate the AC based in circuit capacitance function.
#include "SMU2060.h"
int
DMMOpenCalACCapsl
(
int
nDmm
)
Remarks
This function characterizes the selected range of the AC Capacitance measurement path
and source, which is required prior to making measurements. For better accuracy it
should be performed frequently. It should be performed without test leads. This function
characterizes the stimulus source at the specific frequency associated with the selected
range. It takes about fifteen seconds to complete the process. Make sure to perform this
operation for each range you intend to use.
Parameter Type/Description
nDmm
int
Identifies the DMM. DMMs are numbered starting with zero.
Return Value
Integer error code.
Value Meaning
DMM_OKAY
Operation successfully completed.
Negative Value
Error code
Example
int status = DMMOpenCalACCaps(0);
DMMOpenTerminalCal
SMU2060
SMU2064
Description
Calibrate the Inductance measurement function with open terminals.
#include "SMU2060.h"
int
DMMOpenTerminalCal
(
int
nDmm
)
Remarks
This function characterizes the Inductance measurement path and source, which is
required prior to making inductance measurements. It should be performed within one
hour, before using the inductance measurements. For better accuracy it should be
performed more frequently. The Open Terminal calibration should be performed with the
test leads open. The
DMMOpenTerminalCal
sweeps the inductance stimulus source
across the full bandwidth, and makes measurements at several points. It takes about
twenty seconds to complete the process. For a complete characterization of the
Inductance measurement system it is also necessary to perform the inductance zero
operation with the inductance range and frequency selected, using the Relative function
and with the probes shorted.
