Omega RDXL4SD - Pt 100 Ohm Measurement; T1-T2 Difference Measurement

4-3 Pt 100 ohm measurement
1)All the measuring procedures are same as the Type K
(section 4-1 ) except to select the Temp. Sensor type to
“Pt” by pressing the “Type Button” (3-5, Fig. 1)
once in sequence
until the right down LCD display shows “Pt” text as :
Pt
2)Insert a Pt 100 ohm probe to
PT1 input socket (3-10, Fig. 1)
PT2 input socket (3-11, Fig. 1)
* The Pt 100 ohm measurement only allow
max. two channels ( two probes ) input.
4-4 T1-T2 measurement
When the meter has two installed probes :
Type K/J/T/E/R/S : T1, T2 input socket
Pt 100 ohm : PT1, PT2 input socket
Pressing the “T1-T2 button” ( 3-6, Fig. 1 ), display will
show the difference temperature value between T1, T2
( PT1, PT2 ) as :
T1 °C °C
T1 26.2 1-2
T2 °C °C
T2 26.6 -0.4 T1-T2 value
