1.29 Conguraon menu
Press ‘SQ’ (<) for 1 second to access the ‘conguraon menu’.
For a descripon on how to operate inside the menus see secon
1.27. For a full vision of the ‘conguraon menu’ structure see
secon
1.30.
Access the ‘Input’ (‘InP’) menu to select the input signal range. For a
correct reading, the internal jumper ‘T’ (see secon 1.9) must also be
selected accordingly.
The instrument oers 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 excitaon voltage to power up transducers at terminal 5.
To congure the excitaon voltage, see secon 1.16.
• ‘Thermocouples’ (‘tc’) - select the thermocouple type between
K, J, E, N, L, R, S, B, T and C. The instrument automacally compen-
sates for the thermocouple cold juncon.
• ‘RTD probes’ (‘rtd’) - the ‘rtd’ menu oers temperature resis-
ve probes type Pt (planum) and Ni (Nickel). Select the type of
probe from the available opons Pt100 3 wire, Pt100 2 wire, Pt500,
Pt1000, Ni100, Ni200 and Ni1000. For measures with 2 wires, a
manual compensaon for the wire resistance error is available us-
ing parameter ‘Oset reading’ (‘oFFS’) (see secon 1.22).
• ‘NTC probes’ (‘ntc’) - select the ‘ntc’ menu to congure the input
for NTC probes. To correctly congure the measure for NTC, two pa-
rameters need to be dened : rst 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 informaon on NTC measures see sec-
on 1.14.
• ‘PTC probes’ (‘Ptc’) - select the ‘ptc’ menu to congure 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 informaon on PTC probes see sec-
on 1.15.
