24 Chapter 1 DaqPRO
3. Continuous Mode
In the Continuous mode, DaqPRO must be connected to the PC and the DaqLab software must be
running. In this mode DaqPRO can continue logging indefinitely. The data is automatically downloaded
to the computer, displayed in a real-time graph and saved every 10 minutes. There you don't need to
download the data from the DaqPRO directly as the data is already displayed on the graph.
DaqPRO stores the data until its memory is full. You can download this data only if you stopped logging
before this point.
To operate in Continuous mode select RATE equal to or less than 1/s and SAMPLES = Continuous.
You can also select Continuous mode directly from the DaqLab software.
The maximum sampling rate under Continuous mode is 1 second.
Note: DaqPRO must be set to a display mode other than graphic to enable the Continuous mode.
1.2.10. Programming Rules and Limitations
The following are some rules and limitations you must take into account when programming the
DaqPRO, as DaqPRO integrates all programming limitations automatically. DaqPRO will only allow the
programming of settings that comply with the rules below.
1. Sampling Rate
The number of sensors in use limits the maximum sampling rate:
• Maximum sampling rate with one sensor is 4000/s, when using the Current or
Voltage sensors.
• Maximum sampling rate when using any of the temperature sensors is 1/s. For
instance, when using thermocouples, internal temperature sensors, and so on.
• Maximum sampling rate with two or more sensors of any type is 1/s.
• DaqPRO displays readings in real-time at rates up to 1/s (Continuous mode)
• DaqLab displays online readings at rates up to 100/s, depending on the sensors
connected. If temperature sensors are being used, then the maximum rate is
1/s.
Note: These programming limitations apply to v3.0h or higher of the DaqPRO.
