Introduction
The Aceco FC2002 hand-held frequency counter is a more professional counter, even advanced features such as field
strength measurement and auto hold are incorporated. It is compact, truly pocket-sized, test instrument designed for ease
of use and dependable performance. Supplied as a complete with internal NiCd pack, AC wall charger and 7 section
telescopic antenna.

Controls
1.
Power Switch - This slide switch turns the counter on and initiates a 2 second test of all the LCD segments.
2.
Amp Switch - This slide switch selects either the 1 Meg Ohm high impedance amplifier or 50 Ohm amplifier and
prescale.
3.
Range Switch - This should be switched to the 300 MHz position for frequencies between 1 MHz and 300 MHz and
switched to the 3 GHz position for frequencies between 10 MHz and 3 GHz.
4.
Lite Switch - This slide switch turns the LCD back light on and off.
5.
Filter Switch – This slide switch turns the filter on and off.
6.
Function Button - This selects the frequency or period. This button has four settings. One each for displaying
frequency or period as these are received, and two settings for automatic hold of the first frequency or period
captured.
7.
Hold Button - This holds the current display and stops the counter from counting.
8.
Gate Button - This selects the gate or measurement time. A longer gate time allows counting for longer period and
results in higher accuracy.
9.
Calibration - The calibration adjustment opening is located on the front panel of the counter. This allows access to the
trimmer capacitor that provides about a 10 PPM adjustment range of the time base oscillator. This is not usually
necessary but to do so read a signal of a known frequency before adjusting the trimmer for correct frequency display.
If you calibrate at 4.1943 MHz or above then the counter will be more accurate.
