| Input mode | Count pattern |
|---|---|
| UP | Up-count pattern |
| UP-1 | Up-count variant 1 |
| UP-2 | Up-count variant 2 |
| dn | Down-count pattern |
| dn-1 | Down-count variant 1 |
| dn-2 | Down-count variant 2 |

Choose the required threshold, pulse, hold and reset behavior from the response charts. A one-stage instrument's OUT corresponds to OUT2 of a two-stage instrument. In two-stage operation, OUT1 can use one-shot or hold output. OUT1's preset can be zero in all output modes; OUT2's preset cannot be zero in C, R, P or Q.
