Duration

Relay On/Off

Relay On/off indicates the closing or opening duration in seconds [s]. Specifying the duration is optional. The relay on and relay off times must not overlap for the same relay! Some devices support changeover contacts that are treated as two (dependent) relays, R1 and R2: Activating R1 deactivates R2 and vice versa. Thus, you can control a changeover contact using only one Relay On command. However, you can also ignore the second relay, R2, and control the changeover contact via the Relay On/Off commands of the R1 relay.

Autosampler

The Duration parameter indicates the minimum time that the Autosampler may take to perform Draw or Dispense operations. To prevent evaporation of the sample load, do not draw or dispense more than 10 µl per second. Otherwise, if the Draw time is too short, gas bubbles may result and considerably impair measuring precision.

Sound

The Duration parameter defines for how long (in seconds) the tone is produced for the Sound command.

Note:

Windows XP (64 bit), Windows Vista and Windows 7 operating systems do not support the Sound command.
