Figure 9-7 Limits To Sort 100Ω Resistors (1%, 5%, And >5%) - Keithley 2701 User Manual

9-16 Limits and Digital I/O
The limits are illustrated in
Figure 9-7
Limits to sort 100Ω resistors (1%, 5%, and >5%)
No Beep
Front Panel Operation — For front panel operation, the INSIDE beeper mode must be
used. A normal pitch beep and the message IN indicates that the resistor is within the 1%
tolerance limit
message indicates that the resistor is >1% tolerance but <5% tolerance. This 5% resistor
belongs in Bin 2. For resistors >5%, no beep will sound. Place these resistors in Bin 3.
Remote Operation — For remote operation, make sure both Limit 1 and Limit 2 are
enabled. The following table evaluates the three possible pass/fail combinations for this
example.
Limit 1 result
Keep in mind that a fail condition must be reset before testing the next resistor. Fail can be
reset manually or automatically (see
