User manual - METER SRP-73
“SEtP” - additional threshold value (range -999 ÷ 9999 ). Negative values can be input by
selecting a “-” sign on first digit ( to change value use
[^] and [v] buttons).
Threshold is the medium value of relay hysteresis.
“HYSt”
- Hysteresis of colour indication (range 0 ÷ 999). Full hysteresis is equal to 2x
“HYSt”
parameter. The display colour can change when an input signal is out of
threshold-hysteresis to thhysteresis zone.
Presented parameters should be set to ensure that ” SEtP ” + ” HYSt ” and
” SEtP ” - ” HYSt ” do not exceeds the measure range.
“CrES” - permission to use any local key to acknowledgement of display colour change.
Acknowledgement causes clear of all events generating display colour changes (to
active colour), and restores basic colour of the display.
”oFF” - acknowledgement disabled,
”on” - acknowledgement enabled.
7.3.5. ”HOLd” menu
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
“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 6.3)
“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. If „
HdiS ”=” HOLD ” then setting parameter "timE" = 0.0
causes holding peak value until
[ESC]
button is pressed. If „
HdiS
”=”
rEAL
” then
value
"timE"
=
0.0
means no holding.
“HdiS” - type of displayed values:
”rEAL”
- current value is displayed,
”HOLd” - peak (drop) value is displayed,
“H r1”, “H r2” - relay/LED outputs (R1, R2) operation mode:
”rEAL” - relay/LED operates depend on the current value,
”HOLd” - relay/LED operates depend on the peak (drop) value.
