Using
Resistance
Temperature Detector (RTD)
The calibrator accepts Pt100, Pt1000, Cu50 and Cu100, etc. RTD measurements of
two-wire system, three-wire system or four-wire system are available to calibrator,
among which the three-wire system is particularly applicable to the industrial worksite.
A four-wire configuration provides the highest in accuracy and the two-wire system
the lowest.
To measure temperature using an RTD input, proceed as follows:
1.
Press
to enter into
mode.
2.
Press
to indicate RTD reading. Then the screen will display as shown in
Figure 4-1. If necessary, pressing
continuously to select RTD type.
3.
If connection is based on three-wire system or four-wire system, the calibrator
will switch to three-wire system or four-wire system according to your
connecting type. Press
or
to force the calibrator not to execute
automatic switching.
4.
Connect RTD to the corresponding port according to the connecting type of
‘resistance measurement’.
