I have the following problem with the logger PICOLOG 1216
I need to generate the output square wave signal with a frequency of about 2 seconds.
I would like to use one of the digital outputs.
The only thing I can find it on continuously 1 or 0 (2.5 V or 0 V) or PWM frequency 1.8 ms. It's definitely not enough. How can I increase the frequency?
1) I need to make measurement in 30 points. I bought two PicoLogs 1216. Can I run them in one software? At this moment i try run two same programs in different windows, but disadvantage of this solution is time differential between my measurement. (For example i click start measurement in one window, and then in second window measurement is starting one second later).
You can run two Picolog 1216s under the Picolog software but not the Picoscope software. Just tick the appropriate box for multiple devices when creating a new setup.
Install Picolog software. Then when you run one instance of Picolog, and create a new settings file, you can select the "Multiple Devices" option before specifying the devices and what is connected to each channel.
You are right. Now I can run two PicoLogs at the same time.
1) But there is a trouble with number of channels. I have to measure humidity in 30 points. When I try to export data to "View graph" - maximum is 20.
When I try to export data to "View spreadsheet" - maximum is 16.
So the only way is export data in two smaller groups? I want to export the to excel.
2) Is there any posible way to set 2.5 V on Digital Output when I start recording measurement, and set 0 V when it's not recording? It would be great for information, that the record have ended.
3) I found only this math functions:
( ) - + * / exp log10 ln power mod sqrt
Is there any chance for use (in calbulated parameters):
round()
if()
previous_sample()
?
1. They are the limits for the spreadsheet and graph views, you can use File->SaveAs to save the data file as a CSV file for import into excel.
2 & 3. Unfortunately it is not possible to set/clear a digital output in response to starting/stopping capture, or add new maths functions. The software is now maintenance only so no enhancements are on the development plan.
