What is your customer retention rate? Number of current customers __5086___. Total number of customers served in the past 12 months:__256___. Customer Retention Rate = #1 ÷ #2 = _____ (your percentage of retention). What is your goal for your customer retention rate this year? _____ *It is important to measure the change in this number with regularity. *When it is below 80%, then it is a serious area of concern.
Using very sensitive accelerometers.
It is a brief measure of psychological disturbance,that is reliable and sensitive to changes patients make when they are in therapy
It isn't! Your equipment is just not sensitive enough to measure it.
Put the bug on a sensitive scale.
"The most sensitive gravimeter can measure tiny differences in the Earth's pull."
A semiconductor device that is particularly sensitive to changes in temperature, permitting it to serve as an accurate measure of temperature.
a thermistor is a temperature sensitive resistor - to measure temperature you must measure its resistance and convert that resistance to equivalent temperaturea thermocouple is a temperature sensitive voltage source(i.e. battery) - to measure temperature you must measure the voltage across it and a reference thermocouple at a known constant temperature connected in series with it and convert that voltage to equivalent temperatureNote: Thermistors do not require reference thermistors, thermocouples do require reference thermocouples at a known constant temperature. Thermocouples are more linear than thermistors, making them easier to read accurately. Thermocouples are available that are far more sensitive to small changes in temperature than thermistors.
it measures temperatures between -250 and 1600 degree and it can measure a wider range of temperatures
Electromagnetic radiation is just light. You can measure light with a light meter, which tells you intensity, or a camera sensitive to different frequencies. You can also use a magnetometer (Gaussmeter) to measure the B field component or a voltmeter to measure the E field component.
Scientists measure the magnitude (energy) of an earthquake using a seismograph (sort of sensitive pendulum that records the shaking of the earth).
