Keithley 2700 User Manual

3-42 Basic DMM Operation Model 2700 Multimeter/Switch System User’s Manual
4-wire RTD temperature measurement configuration
The Alpha, Beta, Delta, and Ω at 0°C parameters for the five basic RTD types are provided
in
Table 3-5. Note that these parameters can be modified using remote programming.
The steps to configure 4-wire RTD measurements are provided in Table 3-6. After
pressing SHIFT and then SENSOR, the menu starts at step 1 to select measurement units.
Each time you press ENTER to make a selection, the menu will automatically go to the
next selection. After pressing ENTER for the last step, the instrument will return to the
normal measurement state.
NOTE As shown in Table 3-6, you can select the USER sensor type, but you cannot
change the USER parameters from the front panel. The parameters for the
USER type can only be set using remote programming (see TEMPerature:FRTD
commands in
Table 3-7).
