Intermittent Operation
When the instantaneous flow rate is set to 10 - 49mL/min in the Volume Mode, the intermittent operation is performed by sampling at an instantaneous flow rate of 50mL/min.
Example of Intermittent Operation
When the Volume Mode is selected and the flow rate is set to 10 mL/min and the set volume is 0.1L, after the sampling is started, the pump will pause for about 48 seconds after about 12 seconds of sampling at a flow rate of 50mL/min (samples until the sampled volume per minute reaches 10mL, then pauses). Sampling at a flow rate of 50 mL/min for about 12 seconds and pausing for about 48 seconds are repeated until the set volume of 0.1 L is reached, taking about 10 minutes.
When the Volume Mode is selected and the flow rate is set to 10 mL/min and the set volume is 0.1L, after the sampling is started, the pump will pause for about 48 seconds after about 12 seconds of sampling at a flow rate of 50mL/min (samples until the sampled volume per minute reaches 10mL, then pauses). Sampling at a flow rate of 50 mL/min for about 12 seconds and pausing for about 48 seconds are repeated until the set volume of 0.1 L is reached, taking about 10 minutes.
