terminals. Select MANUAL and open the screen to fill out the
obtained reading. Press EXE to enter. Note that in this mode
temperature changes at the instrument terminals can easily create
calibration errors.

TO MEASURE A RTD

Go through the RTD measure menu and make the selections as
required. Press EXE to open the working screen; the measurement
reading is shown in the upper window. Resolution is 0.1 or 0.01
degree depending on selected RTD type. The excitation current is
0.9 mA. Wiring can be 2, 3 or 4 wire. The 4-wire method provides a
true measurement of the voltage drop across the unknown resistance
at a constant excitation current.
