The CORNET ED65 is a single axis RF meter for frequencies between 100 MHZ to 6 GHz. It has a digital LCD display with a lot of information and in addition a color bar led display. The CORNET ED65 can measure from 1 uW/m2 to 0.58 W/m2.
On the CORNET ED65 LCD you can fine the level of the EMR represented in several ways, In large numeric digits the CORNET ED86 can displays both the dBm units the uW/m2 units (user can chose using upper operation button). On the right side of the LCD the CORNET ED65 displays the last 32 measurements values into a histogram shape (couple of measurement are done every second). In addition there is a led color bar next to the right side of the LCD. The histogram gives the operator a very good indication of the EMR levels over the last few seconds and makes the job of finding EMR sources much easier.
The CORNET ED65 is equipped with a back light for the LCD display, which can be turned on by pressing the upper function button while in HOLD mode and which is automatically turned off after 20 seconds. The LCD back light makes it possible to use the CORNET ED65 at night and in poor light conditions. The lower button is used to freeze the display on the last measured value (Hold function).
A big On-Off button is located under the LCD and above the 2 function buttons in the front of the CORNET ED65 (gets pressed very easily when the meter is in the bag or not in use).
The CORNET ED65 has an internal antenna and it uses a 9V battery (easy access from the back of the CORNET ED65). The battery kept the meter working for more than one hour with the back light on. I recommend having a spare battery or even several rechargeable batteries if you use the CORNET ED65 more than once in a while.
Advantages: · A lot of info on the LCD. · LCD Back light. · Histogram graph. · Display of Max values (only in some modles). · The internal antenna saves place and maakes it easier to store and move the meter. · Cheaper than the ED85 and the ED25.
Disadvantages: · One axis only · Short battery life, better to have rechargeable batteries. · At first some people can find it hard to follow all the info on the LCD. · ON-OFF button is easily pushed when inside the bag.
Button line: The CORNET ED65 will suit you if you are looking for a RF meter for up to 6 GHz, and if you are not afraid from a lot of data being presented on the same small LCD at the same time. It is cheaper than the ED85, ED75 and the ED25.
