Channel B Cursors

Hello again Rich, Thank you very much for the kind words. With regards to your cursor question, you can either measure ChA or ChB with each of the two available cursors. The way to do this, is to drag the mouse on the display with your left mouse button to create a ChA cursor, and to drag the mouse ...

Hi Rich, You can set the maximum number of samples per scope trace in the Settings|Options|Advanced dialog. This will give you an idea of the time-resolution. Alternatively you can save the trace as a .txt file and count the number of readings in a spreadsheet. Your concept of vertical resolution is...

0(4)-20mA Sensors on an ADC-16/ADC-11

Hi Scott, I'm afraid you'll have to do some maths! Resistance = Voltage / Current Therefore you will need to know the voltage drop and current that you need to draw across a resistor in order to determine the value you require. I will give you a common example which is used to adapt the ADC-16 or AD...

Hello Steve, Its not really possible to change the External channels into a PH probe input. The main reasons for this are that the PH Probe is bi-polar (approx. ±576mV) and the Ext inputs are unipolar (0 to 2.5V). Also, the PH input is heavily filtered, so you would need to apply this filtering your...

Hi Rich, We use 'C' for most of our applications. There are no functions available to link directly into PicoScope (its a stand-alone application). PicoLog however, uses Dynamic Data Exchange so if you know how to program with this, you will be able you retrieve data from the application (I know tha...

Thanks for the tip Rich,

I'm sure this thread will help quite a few users with noise problems. Another possible way of countering noise on laptops is to connect an earth point (if you have the luxury of an earthing screw on the back of your laptop!)

Hello Laurie, I didn't realise your unit was so old, this explains the problem. The version 1 ADC-12 only works with the DOS application (this was all we supported at the time). Unfortunately you will have to continue using the unit with DOS as this product can't be used under windows. Alternatively...

Hello Laurie, First of all, you've done exactly the right thing by first checking that your hardware works in DOS mode :). Your parallel port mode should be on SPP or Normal , so check that you have left the BIOS on either of these. There are two other BIOS settings you will need to check: The Input...

Hi Lars, I'm afraid I can't replicate the problems you are having. Have you tried checking the function call in the diagram view to check that it is looking in the right place for adc1632.dll ? C:\LABVIEW\USER.LIB\adc1632.dll should be correct, but your installation directory may be different. We ca...

Rod, First of (I know its elemetry but...) check the power cable is securely in and the red light is on. Which operating system are you using?

We don't at present have the in-house expertise to support VB .net and I'm afraid I don't know the answer to your question. Perhaps we will move into this in the future :). In the mean...

Hi John, You should have said that you wanted to interface with PicoLog directly I assumed you wanted to write both server & client software.

ETS in Pseudo-Code

Hello Style,

I believe you have contacted me directly regarding this. Once our software department has got back to me with a step-by-step psuedo-code guide on ETS, I'll post it here for other forum readers to benefit as well.

Kind Regards,
