MAX Hold
The maximum value of a type of numeric data can be held.
• You can determine the type of data whose maximum value will be held using a user-
defined function. The operators for the measurement functions are shown below in
this format: measurement function: equation for defining the MAX hold.
Urms: URMSMAX( )
Umn: UMEANMAX( ) Udc: UDCMAX( )
Urmn: URMEANMAX( ) Uac: UACMAX( ) Irms: IRMSMAX( )
Imn: IMEANMAX( ) Idc: IDCMAX( ) Irmn: IRMEANMAX( )
Iac: IACMAX( ) P: PMAX( ) S: SMAX( )
Q: QMAX( ) U+pk: UPPEAKMAX( ) U-pk: UMPEAKMAX( )
I+pk: IPPEAKMAX( ) I-pk: IMPEAKMAX( )
* To hold the MAX value of Urms, enter URMSMAX ( ) in the equation for the user-defined
function.
One symbol from E1 to E4 (

functions: URMSMAX( ), UMEANMAX( ), UDCMAX( ), URMEANMAX( ), UACMAX( ),
IRMSMAX( ), IMEANMAX( ), IDCMAX( ), IRMEANMAX( ), and IACMAX( ).
