4.2.5 Measurement Function
4.2.5.1 Measurement Function
The measurement function is classified into the following types:
1. Voltage measurement function
2. Current measurement function
3. Resistance measurement function
Resistance values are obtained by dividing voltage by current.
For more information on resistance value calculation for the pulse source mode, refer to Section
4.2.5.4, “Measurement Delay Time and Measurement Value.”
The measurement function has two modes. In one mode, the measurement function can be selected
independently from the source function. In another mode, the linked measurement function is set
according to the source function.
Use 6) Measure and 6) Mfunc Link in the menu to switch the mode.
When the link mode is selected, the measurement function is set as follows by changing the source
function:
• Voltage source function/current measurement function VSIM
• Current source function/voltage measurement function ISVM
Also, immediately after the link mode is set, the measurement function changes according to the currently
set source function as shown above.
NOTE: The resistance measurement function shows the following messages if it cannot
normally execute resistance value calculation.
VSource=0: The voltage source value is 0.
HiLimit RM: HI limit status
LoLimit RM: LO limit status
4.2.5.2 Source Value Monitor
The 6253 monitors the source values for DC voltage and current, separately from the measurement
function.
The integration time and measurement timing are shared by the measurement function. The measurement
range is fixed to the source range.
4.2.5.3 Measurement Ranging
The measurement range is determined by the relationship between the measurement auto range ON/OFF
and the source or measurement function.
