Close
The comparator of the current parameter is closed.
Absolute value
Switch comparator to absolute value comparison mode.
Relative value %
Switch comparator to Relative value comparison mode.
Direct reading value SEQ
Switch comparator to Direct reading value comparison
mode.
5.1.2[nominal value] input
SCPI Command: COMParator:TOLerence:RNOMinal <float>
SCPI Command: COMParator:TOLerence:VNOMinal <float>
The absolute value and relative value comparison method must input the nominal
value.Direct reading nominal values do not participate in the calculation, but in the
nominal range, the[ nominal ]value of resistance will participate in the range selection, so
in the[ nominal ] range, no matter what the comparison method, the correct nominal value
of resistance needs to be input.
Input nominal value:
The first step is to go to < Settings > page.
The second step is to use cursor keys to select "resistor nominal" or "voltage
nominal" fields.
The third step is to use numeric keys to input data, and units use function keys to
select them.
5.1.3 [Lower limit] and [ upper limit] setting section
SCPI Command: COMParator:TOLerence:RLMT <lower>,<upper limit>
SCPI Command: COMParator:TOLerence:VLMT <lower>,<upper limit>
Input limit value
The first step is to enter the < comparator > page.
The second step uses the cursor key to select the[ lower limit of resistance] or the[ lower
voltage limit ]field.
The third step is to use numeric keypad to input data.
Relative value % does not need to select unit rate. Please input percentage
percentage.
Absolute value and direct reading SEQ, please use the function key selection
unit.
The fourth step is to use the cursor key to select the upper limit of resistance and the
lower limit of resistance.
The fifth step is to use numeric keypad to input data.
The sixth step is to repeat 2~5 to complete data input from other files.
Note! The instrument shares the same storage space for three comparison methods,so it
is necessary to reset the comparator data after switching the comparisons.
5.2 Short circuiting zero
Communication instruction
：
CORRect:SHORt
In order to achieve high-precision measurement, zero calibration is necessary. Short
circuit clearing can effectively offset the stray resistance of the test line.
