Math Group - YOKOGAWA WT110 User Manual

Appendix 2.3 Commands
2.3.8 MATH Group (applies to WT110/WT130 with ROM version 2.01 or later)
The commands in the MATH group are used to make settings relating to, and to make inquiries about the computing function.
The same function can be performed using the "MATH" menu of the [SETUP] key of the front panel.
:
:MATH
MATH?
Function Queries all settings related to the computing function
Syntax
MATH?
Example
MATH?→:MATH:TYPE
ARITHMETIC;ARITHMETIC ADD
MATH:ARIThmetic
Function Sets/queries the computing equation of the four
arithmetic operations.
Syntax
MATH:ARIThmetic
{ADD|SUB|MUL|DIV|DIVA|DIVB}
MATH:ARIThmetic?
Example
MATH:ARITHMETIC ADD
MATH:ARITHMETIC?→:MATH:ARITHMETIC ADD
Description If [MATH:TYPE] is not set to [ARIThmetic], this
command will be meaningless. The computing
equation selections are as follows:
ADD : display A + display B
SUB : display A – display B
MUL : display A X display B
DIV : display A / display B
DIVA : display A / (display B)
DIVB : (display A)
MATH:CFACtor
Function Sets/queries the computing equation of the crest factor
Syntax
MATH:CFACtor
{(V|A),(<NRf>|ELEMent<x>)}
<x>= 1
1, 3
1 to 3 (WT130 three phase four-wire
MATH:CFACtor?
Example
MATH:CFACTOR V,1
MATH:CFACTOR?→:MATH:CFACTOR V,1
Description If [MATH:TYPE] is not set to [CFACtor], this command
will be meaningless.
