Programming Rules and Limitations

The following are some rules and limitations you must take into account when programming the DaqPRO. As DaqLab integrates all programming limitations automatically, setting up DaqPRO via DaqLab will only allow the programming of settings that comply with the rules below.

Sampling rate:

The number of sensors in use limits the maximum sampling rate:

1. Maximum sampling rate with one sensor is 4000/s
2. Maximum Temperature sampling rate is 1/s
3. Maximum sampling rate with two sensors or more is 1/s
4. Maximum sampling rate with two PT100 sensors or more is once every 10 seconds.
5. Maximum sampling rate five sensors or more where at least one is NTC or thermocouple (J, K, or T) is once every 10 seconds.
6. Maximum sampling rate for seven or more sensors is once every 10 seconds.
7. Maximum sampling rate for eight PT100 sensors is once every minute.
8. DaqPRO displays readings in real time at rates up to 1/s
9. DaqLab displays online readings at rates up to 100/s

Sampling points:

Increasing the number of active inputs limits the number of sampling points one can choose. The following condition must be always satisfied:

DaqPRO’s memory is sufficient for 512,000 samples.

The table below lists the maximum number of sampling point according to the number of sensors:

Continuous sampling

· Continuous sampling is possible up to a maximum sampling rate of 1/s.

· The data must be presented in a display mode other than graphic.
