Below is some model-specific information to help you
locate your instrument response.
DAQ Systems have are four models: the 4, 4CH and 5V
versions of the DAQ24USB use the CS5532 ADC chip, and the XR uses the ADS1255 chip.
FIR filters are the same for dataloggers using the CS5532 chip, but sensitivities vary.
The 4CH and 5V dataloggers have a Low and High sensitivity mode. Sensitivities are as
follows:
- 4.194310^5 Counts/V for the DAQ24USB-4, and the
DAQ24USB-4CH and DAQ24USB5V at Low sensitivity
- 2.79620310^6 Counts/V for the DAQ24USB-4CH at High sensitivity
- 2.843596*10^6 Counts/V for the DAQ24USB-5V at High sensitivity
The XR has different sample rates and uses different FIR filters that dataloggers using the CS5532 chip.
DAQ24USB-4
This model uses the CS5532 ADC chip and has the same FIR filter response as the DAQ24USB-4CH and DAQ24USB-5V dataloggers. Its ADC scale factor is 4.1943e+5 counts/V.
DAQ24USB-4CH
This model uses the CS5532 ADC chip and has the same FIR filter response as the DAQ24USB-4 and DAQ24USB-5V dataloggers. Its ADC scale factor is 4.1943e+5 counts/V when recording at Low sensitivity and 2.796203e+6 counts/V at High sensitivity.
DAQ24USB-5V
This model uses the CS5532 ADC chip and has the same FIR filter response as the DAQ24USB-4 and DAQ24USB-4CH dataloggers. Its ADC scale factor is 4.1943e+5 counts/V when recording at Low sensitivity and 2.843596e+6 counts/V at High sensitivity.
DAQ24USB-XR
This model uses the ADS1255 ADC chip, giving it a different response from models using the CS5532 chip. It also had different sample rates available.
