Yes, solar cells are available from fourtec.
Connect the solar cell to the 9 - 12V input on DaqPRO's left panel.
Make sure to disconnect the Internal NiCad battery so the solar cell power will not be wasted on charging the batteries

Back to DAQPRO FAQs

Turn the DaqPRO on. Make sure that input 1 is empty.

Use the Forward and Backward arrows to navigate to the System information icon and then press the Enter button

DaqPRO will display the battery level in the system information screen.

Note: v3.0h of the DaqPRO does not have this feature.

• The trigger condition has not been fulfilled
• The trigger condition was fulfilled, but the time period was too short (less than 300mS)

The internal 3V battery is dead or has been removed from the logger, resulting in the DaqPRO memory being cleared.

In continuous mode DaqPRO will save over the old data when the memory is full, beginning with the earliest data recording. When logging ends data can be downloaded to the PC.

If DaqPRO is connected to the PC and the DaqLab software is running, the data is automatically downloaded to the computer, displayed in a real-time graph and saved every half an hour.

DaqPRO should be checked for calibration once a year. We recommend to send DaqPRO to a certified calibration laboratory or to return DaqPRO to fourtec for factory calibration.

Back to DAQPRO FAQs

The calibration procedure updates both the DaqPRO and the software. You will see correct readings both in MicroLog’s display and in DaqLab.

The type and 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

In order to use DaqPRO as a frequency or pulse meter connect the signal wires to I/O 8 screw terminals, and select Frequency or Pulse counter for input 1 from the Setup menu.

DaqPRO is IPS4 proof and is NOT water proof. To operate in harsh weather conditions you weed need fourtec’s Weather box P/N DT177.

The DaqPRO has a very large isolation between its inputs. Typically the crosstalk between channels is -80dB. Additionally the DaqPRO has floating mechanism that ensures that all (-) inputs are not connected internally to a common ground. This is a very useful feature, however in cases where sensors are located in a noisy environment, it may cause ground noise and ground loops problems. This may cause an effect of one sensor on other sensor readings. The solution in this case is to connect all (-) inputs together with one external wire.

 If the internal battery is removed:

• The DaqPRO's calibration settings are lost. You will have to restore them by loading the factorydefaults.daq or the logger's .cal file using DaqLab.
• The DaqPRO's memory is lost i.e. all files and notes stored on the logger.
• The DaqPRO's S/N is reset to zero. It will be restored when loading the calibration settings to the logger.
• The DaqPRO's internal clock is reset. Update the clock settings by establishing communication between the logger and DaqLab.

To reset the DaqPRO:

1. Open the DaqPRO case.
2. Disconnect the main battery pack and remove the 3V lithium battery .
3. Wait at least two minutes and then reconnect the battery pack and place the lithium battery back in its compartment.
4. Turn on the DaqPRO. You will see a blank screen. Turn off the unit.
5. Turn on the DaqPRO again and see that the unit initializes and that the main menu loads.
   
   Resetting the DaqPRO will clear the logger memory as well as lose the calibration values of the logger.
   Following a reset, you will have to load the DaqPRO calibration settings into the logger. Contact fourtec for further support.

This means that the DaqPRO's memory has become corrupted in some way, affecting the calibration values of the logger thereby causing these inaccurate readings.  You will have to reset the logger to restore normal readings but note that you will then have to recalibrate the DaqPRO.
