This menu contains parameters connected with peak detection function. See also full description of
the peak detection function in paragraph:
DETECTION OF THE PEAK VALUES
7.3.3. ”HOLd” menu
The
“Lo r”
parameter determines lower border of the permissible range calculated due to
expression: I
min
= 4 mA - 4 mA ×
“Lo r”
%.
The
“Lo r”
value can be set from 0 to 12.4%.
Parameter
“Hi r”
determines the upper border of the permissible range accordingly to the
expression: I
max
= 20 mA + 20 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.
“modE”
- the type of detected changes of the input signal, can be set to values:
“norm”
- peaks - peak and next drop of the input signal of value equal at least
“PEA”
,
“inv”
- drops - drop and next peak of the input signal of value equal at least
“PEA”

“PEA”
- minimal detected signal change classified as peak or drop (see Figure 6.2)
“timE”
- maximum time of displaying of the peak (drop) value, can be set from 0.0 to 19.9 sec, with 0.1 sec. resolution.
“HdiS”
- type of displayed values:
“H r1”
- relay/LED output R operation mode:
“rEAL”
- current value is displayed,
“HOLd”
- peak (drop) value is displayed,
“rEAL”
- relay/LED operates depend on the current value,
“HOLd”
- relay/LED operates depend on the peak (drop) value.
