User manual - METER SRT-147
•
If option “
noCH
” is selected for
“AL”
parameter, behaviour of the relay may
depend on
“FiLt” parameter
in some cases
. If “FiLt” is set to big value and the
input signal drops, result value of the measure will change slow, causes of
turning on or off relay due to thresholds values. The critical situation is slowly
detected, so it is impossible to predict the relay state in that situations.
•
If parameter „
AL
” = „
on
”, the relay will be turned on in the critical situations,
even if his parameter
“modE”
=
”noAC”.

“bEEP” menu
This menu contains options connected with acoustic signal :
"
AL
”
- if this parameter is set to “
on
”, any critical situation causes by acoustic signal
"
r1”
- if this parameter is set to “
on
”, activation of relay
R1
causes by acoustic signal
"
r2
"
- if this parameter is set to “
on
”, activation of relay
R2
causes by acoustic signal
"
r3
"
- if this parameter is set to “
on
”, activation of relay
R3
causes by acoustic signal
"
r4
"
- if this parameter is set to “
on
”, activation of relay
R4
causes by acoustic signal
Acoustic signal (turned on by e.g. relay ) can be turned off by pressing of any
button
7.3.3.
“inPt” menu
This menu presets the measurement input:
“
tYPE
"
- type of the input / sensor. This parameter can be set to values:
”
Pt 1
”
- Pt-100 input,
”
Pt 5
”
- Pt-500 input,
”
Pt10
”
- Pt-1000 input.
”FiLt”
- this parameter sets filtration rate. It can be set to values from 0 (no filtration ) to 5
(strongest filtration – time window about 2 sec).
“toFS”
- offset (expressed in 0.1°C, range ± 9.9°C.). This parameter allows shifting of
measurement scale, and express value added to calculated (measured) result.
