User manual - METER SRP-94-XC
”Hi r” - this parameter define the expansion of nominal range in percent. It
determine the permissible range of input signal (Figure 7.1).
The permissible range allow user to exceed the
nominal range
of input signal.
If input value is contained in the permissible range a proper result is displayed.
If input signal exceeds this range (defined by
“Hi r” ), “-Lo-” or “-Hi-” warning
is displayed depend on input signal value.
Figure 7.1 E xample of definition of permissible range of input signal -
“ Hi r ” parameter ( “60” mode)
Parameter
“Hi r”
determines the upper border of the permissible range accordingly
to the expression (for all modes).
For example if input is set to
“60” mode, then upper border is calculated due to
expression: U
max
= 60 mA + 60 mA × “Hi r” %.
The value of “Hi r” can be set from 0 to 19.9%
In example no 1 of the DISPLAY VALUES CALCULATION paragraph the
procedure of the permissible input range determining is presented in details.
If the measurement value do not exceeds permissible measurement range but
displayed value exceeds range -999 ÷ 9999, the warning
”-Ov-”
is displayed rather
than the calculated result.
7.3.4. ”OutP” menu
This menu contains parameters of current output control. Menu is available if the device
is equipped witch current output.
Current output can be controlled depend on both present measured value and peak
value (if peak detection is enabled).
“Omod” - current output mode, can be set to values:
” oFF ” - current output disabled ,
” 0-20 ”
- current output enabled with 0 ÷ 20 mA mode ,
