Reset by external signal TARA (clamp nr. 5). Reset signal should has length min. 10ms, and
interval between next reset signals should not be shorter than 0,5 sec.
Picture. 3 Reset of sensor by external signal TARA.
Reset value is remain at non-volatile memory of digital processing unit.

Filtering of measurements
Parameters
8. RATE and 9.FILT
have influence on indications durability.
Parametr
8. RATE
specifies measurement frequency(10Hz, 80 Hz). Lower frequency provides
more stabile indications.
Parametr
9. FILT
specifies filtration level of digital averaging filter. Higher filtration value
(max. 99) provides more stabile indications, however, response to changes of the measured
signal is slower.
4.4
Units of measurement
Units of measurement are set by
7. UNIT
parameter. The user has following units for selection:
1
N
– Newton’s, 2
kN
– kilonewtons, 2
g
– grams, 3
kg
– kilograms, 4
T
– tones, 5
Funt
-
pound
Additionally
12. DP
parameter specifies number of decimal places of indicated value. When DP will
set on 0 digital processing unit will display only complete part of measurement. For DP = 4 result will
has four decimal places.
Parameter DP influence also on measurement range of set parameters. If
DP
= 0, then
P1
,
P2
,
P3-H
settings
, could be change only at complete part in range -99999 do 999999. If
DP
=4 parameters
above could be change in range of -99.9999 up to 99.9999.
5.
Configuration of relay outputs
MD150T digital processing unit has 2 relay outputs PK1 and PK2 which can be switched on/off
depending on current measurement value. The following parameters are used for relay outputs
configuration:
1. P1
-
activation (deactivation) threshold of PK1 relay
2. P2
-
activation (deactivation) threshold of PK2 relay
