1.29.1 Input signal ranges
Access the 'Input' ('InP') menu to select the input signal range. For
a correct reading, the internal jumper 'T' (see section 1.9) must also
be selected accordingly.
The instrument offers the following signal ranges :
•
'AC signals' ('Ac') - select a range between 600 Vac, 200 Vac,
20 Vac, 2 Vac, 200 mVac, 60 mVac, 5 Aac and 20 mAac. The AC
measure ranges provide 'True RMS' reading.
•
'DC signals' ('dc') - select a range between ±600 Vdc, ±200 Vdc,
±20 Vdc, ±2 Vdc, ±200 mVdc, ±60 mVdc, ±5 Adc and ±20 mAdc. Dc
measures are bipolar.
•
'Process' ('Proc') - select 4/20 mA or 0/10 Vdc. The instrument
provides excitation voltage to power up transducers at terminal 5.
To configure the excitation voltage, see section 1.16.
•
'Thermocouples' ('tc') - select the thermocouple type between
K, J, E, N, L, R, S, B, T and C. The instrument automatically
compensates for the thermocouple cold junction.
•
'RTD probes' ('rtd') - the 'rtd' menu offers temperature resistive
probes type Pt (platinum) and Ni (Nickel). Select the type of probe
from the available options Pt100 3 wire, Pt100 2 wire, Pt500,
Pt1000, Ni100, Ni200 and Ni1000. For measures with 2 wires, a
manual compensation for the wire resistance error is available
using parameter 'Offset reading' ('oFFS') (see section 1.21).
•
'NTC probes' ('ntc') - select the 'ntc' menu to configure the
input for NTC probes. To correctly configure the measure for
NTC, two parameters need to be defined : first the resistance of
the NTC probe at 25º ('r.25') and parameter 'beta' ('bEtA'). The
instrument accepts beta values between 2000 and 5500. For more
information on NTC measures see section 1.14.
•
'PTC probes' ('Ptc') - select the 'ptc' menu to configure the input
for PTC probes. Select K121 for PTC probes from the KTY-121
family (KTY81-121 and KTY82-121). Select K220 for PTC probes
from the KTY-210 family (KTY81-210 and KTY82-210) and KTY-220
(KTY81-220 and KTY82-220). For more information on PTC probes
see section 1.15.
