14.3.8 MATH Group
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.

14.3 Commands
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
×
display B
DIV : display A / display B
DIVA : display A / (display B)
2
DIVB : (display A)
2
/ display B
MATH:AVERage
Function Sets/queries the average active power
computation.
Syntax MATH:AVERage {W[,(<NRf>|
ELEMent<1-3>|SIGMa)]}
MATH:AVERage?
Example MATH:AVERAGE W,1
MATH:AVERAGE? -> :MATH:AVERAGE W,1
Description If [
MATH:TYPE
] is not set to [
AVERage
], this
command will be meaningless.
MATH:CFACtor
Function Sets/queries the computing equation of the
crest factor
Syntax MATH:CFACtor {(V|A),(<NRf>|
ELEMent<x>)}
<x>= 1 (WT210 single-phase
model)
1, 3 (WT230 three-phase
three-wire model)
1 to 3 (WT230 three phase four-
wire model)
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.
