Keithley 2750 User Manual

7-22 Scanning Model 2750 Multimeter/Switch System User’s Manual
NOTE Channels for an advanced scan can be configured using different mX+B units
(i.e., ° and ¾), temperature sensors (I.e., 4-wire RTD and thermistor), and mea-
surement type (i.e., OCOMP ohms and DCV).
However, when readings are recalled from the buffer, the display may not indicate
the correct mX+B units symbol or annunciator for each channel. For example,
assume one channel used OCOMP ohms, while a second used ¾2. When the read-
ings are recalled, the OCOMP annunciator may remain on for both channels.
This display anomaly is due to memory limitations. Preserving the mX+B units
and annunciators for each channel would reduce the number of readings that
could be stored in the buffer.
