Command Reference
Command Reference
RM
This command specifies the auto range operation for the current measurement.
Syntax
RM chnum , mode [, rate
]
where the rate parameter is available for mode =2 or 3.
Parameters chnum : Current measurement channel number. The value must be slot number
where the module has been installed. Integer expression. 1 to 8 (1 and 5
are not available for HPSMU). See
Table 4-1 on page 4-9 .
mode : Range changing operation mode. Integer expression. 1, 2 or 3.
where current1 and current2 are given by the following formula:
current1 = measurement range
×
rate /100
current2 = measurement range
×
rate /1000
For 200 mA range, they must be:
current1 =200 mA
×
rate /100
current2 =100 mA
×
rate /100
For example, if measurement range =10 mA and rate =90, these values
are as follows:
current1 = 9 mA
current2 = 0.9 mA
rate : Parameter used to calculate the current value. Numeric expression.
11 to 100. Default value is 50.
Example
Statements
OUTPUT @E5270;"RM 1,2"
OUTPUT @E5270;"RM 2,3,60"
mode Description
1 Initial setting. If you set mode =1, do not set rate .
2 If measured data
≥
current1 , the range changes up after
measurement.
3
If measured data
≤
current2 , the range changes down
immediately, and if measured data ≥ current1 , the range
changes up after measurement.
