yes, it is possible to measure capacitance using only one 555 timer for it's monostable operation. When the output is high time is given by the equation t=1.1RC. From the output pulse measuring t(high) and then by measuring R we can calculate the capacitance.
While it is possible that the company producing the capacitor is using the NF as an identification tool, usually we would expect nF to specify the capacitance or value of the capacitor. For example, a capacitor with the value of 10nF ought to have a capacitance of about 10 nano Farads. This is equivalent to 10*10-9 Farads.
In shunt clippers, when the diode is in off condition, transmission of input signal must take place to output. But in the case of high frequency input signals, diode capacitance affects the operation of circuit adversely and the signal gets attenuated (which means that, it passes through diode capacitance to ground).
If you haven't noticed pin 2 is sensitive to 50ua you can us that practically from anywhere to switch states
only earthing can not be measure. Anyone can only measures the voltage and the current with respect to the earthing .Thus it is impossible to measure the earthing.
You measure voltage using a voltmeter which involves measuring the electrical potential difference between 2 points in an electrical circuit.

Capacitance is resistance (not ohms) to a change in voltage using stored charge. The differential equation of a capacitor is dv/dt = i/c. This means that the rate of change of voltage is directly proportional to current and inversely proportional to capacitance.
Using the information given in the question, it's not possible to know.
using a timer
You set the 10 minute timer for 9 minutes and the 7 minute timer for the full 7 minutes.
its cheap and easy to use.
A CDN will be more accurate, but a regular kitchen timer, if used properly, is very accurate as well.
If the machine is not using the salt, it means that it is not going through its regeneration cycle. There may be something wrong with it, or it is not set properly. It's possible that the timer is not working.
Yes, this television can be set to turn on and off using the timer function. Just set the time in the menu.
