1.29 Configuration menu
Press ‘SQ’ (
<
) for 1 second to access the ‘ configuration menu ’.
For a description on how to operate inside the menus see section
1.27
. For a full vision of the ‘
configuration menu
’ structure see
section
1.30
.
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 mea -
sure 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 compen -
sates for the thermocouple cold junction.
• ‘ RTD probes ’ (‘ rtd ’) - the ‘ rtd ’ menu offers temperature resis -
tive 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 us -
ing parameter ‘
Offset reading
’ (‘
oFFS
’)
(see section 1.22).
• ‘ NTC probes ’ (‘ ntc ’) - select the ‘ ntc ’ menu to configure the input
for NTC probes. To correctly configure the measure for NTC, two pa -
rameters 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, and values of R25 between
1.0 K and 200.0 K. For more information on NTC measures see sec -
tion
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 sec -
