Digital Multimeter with PC Interface
(220-0168) Hints and Tips Faxback Doc. # 17322
COM displays in secondary display what is being sent to the PC. This is
where the black wire goes.
Dual Function displays AC and Frequency or Frequency and AC.
MIN displays the Minimum of the changing value.
CMP displays the comparison between High and Low readings.
Q: When in the Scope mode and measuring frequencies, an error message
comes up indicating the function switch has been changed which has
not. There seems to be an error in the software because the DMM
changes ranges automatically in this function.
A: Version 1.21A of the software fixes this problem.
Q: Can both measurements be recorded in the Dual Mode?
A: No.
Q: A problem occurs when using the frequency function and the reading
crosses the boundary of 20 kHz. It autoranges to the 20 MHz range at
that point. The software then thinks the range switch has been moved
and stops the display and indicates that the range switch has been
moved, stops the display and indicates that the range switch should
not be changed while reading data.
A: This may be a software problem. Use the 1.21A version of the
software.
Q: Is there any way to read dual readings (AC and Freq)?
A: Yes, dual readings (AC/Freq) can be obtained on the meter, not on the
PC. Refer to Page 37 of the owner's manual for information on this.
