Parameter setting
Batch setting
Any setting from 0 to 999999 counts
Preset by front-panel control keys (in the batch setup mode “RUN”).
Grand total setting
Any setting from 00000000 to 99999999 counts
Preset by front-panel control keys (in the setup mode “SET”).
Initial-and final-count setting
Any setting from 0 to 999 counts (default: 80) Set by front-panel control keys.
If set at “0,” the valve opens and closes in the single stage ( in the setup mode “SET”).
Missing pulse setting
Any setting from 1 to 15 sec. (default 10 sec.) Preset by front-panel control keys.
When set to “0,” the alarm is disabled (in the setup mode “SET”).
Overshoot setting
Any setting from 1 to 99 counts (default 10) preset by front-panel control keys.
If set to “0,” the alarm is disabled (in the setup mode “SET”).
Scaler setting
