Explanation
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 (
Σ
) can be entered between the parentheses of these
functions: URMSMAX( ), UMEANMAX( ), UDCMAX( ), URMEANMAX( ), UACMAX( ),
IRMSMAX( ), IMEANMAX( ), IDCMAX( ), IRMEANMAX( ), and IACMAX( ).
•
One symbol from E1 to E4 (
Σ
) can be entered between the parentheses of these
functions: PMAX( ), SMAX( ), and QMAX( ).
•
One symbol from E1 to E4 (
Σ
) can be entered between the parentheses of these
functions: URMSMAX( ) and UMEANMAX( ).
•
One symbol from E1 to E3 can be entered between the parentheses of the functions
including and between UPPEAKMAX( ) to IMPEAKMAX( ).
•
The maximum values of the data above are held while the MAX hold function is
enabled.
•
The values in numeric value lists and transmitted values are also held at their
maximum levels.
Note
• When MAX hold functions have positive and negative values, the absolute values are
compared to determine the maximum value.
• To reset held maximum values, turn MAX hold off, and then turn it on again.
