Model 2700 Multimeter/Switch System User’s Manual Limits and Digital I/O 9-17
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.
Keep in mind that a fail condition must be reset before testing the next resistor. Fail can be
reset manually or automatically (see
Table 9-2 , CLEar command).
Digital outputs
With the digital outputs of the Model 2700 enabled, the digital outputs will respond as
follows for each resistor reading:
Limit 1 result Limit 2 result Resistor tolerance Bin assignment
Pass Pass > 1% 1
Fail Pass > 5% 2
Fail Fail >5% 3
LO limit 2 LO limit 1 HI limit 1 HI limit 2
