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( )
Urmn: URMEANMAX( )
Imn: IMEANMAX( )
Iac: IACMAX( )
Q: QMAX( )
I+pk: IPPEAKMAX( )
* 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.
