Accuracy (Typical): ± (1 sample interval + 50 ppm * reading + 0.6 ns) Resolution: 4 digits Trigger Signal Frequency Readout Method used to make measurement: Provides the user with a means of identifying the frequency of trigger signals with higher accuracy than the Automatic ...
Logging feature means you can set up your oscilloscope to save user- specified triggered waveforms to a USB memory device for up to 24 hours. You can also select the "infinite" option for continuous waveform monitoring. With this mode you can save your triggered waveforms to an external USB ...
This means that an increase in the temperature of an aqueous system in which UCON Antifoams are present causes a decrease in solubility of the UCON Antifoam being used. At or above the cloud point (the initial effective temperature), the UCON Antifoam separates from solution and acts as an ...
If you have RO/DI it means your DI is exhausted. I have RO only and it works just fine with a reading of 9 from 400 input. 09/18/2011, 10:00 PM #8 Raggamuffin Registered Member Join Date: Oct 2006 Location: Brandon SD. Posts: 541 5 would be my absolute limit and I ...
