Controls
- Power Switch - This slide switch turns the
counter on and initiates a 2 second test of all
the LCD segments.
- Hold Button - This holds the current display and
stops the counter from counting.
- 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 an 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.
Warranty
Aceco
Electronics, Corp.
guarantees the counter and accessories for one year
against defects in manufacture. This warranty does not
cover items that have been modified, subject to
unauthorized repairs, misuse or abuse. This warranty
does not cover damage caused by excessive power levels
applied to the signal input. Never make any kind of
connection between the counter and a transmitter.
Hints
And Tips
- NiCd
Operation
This
frequency counter can operate for up to six hours
from its fully charged NiCd batteries. They are
charged when the unit is plugged into the supplied
AC/DC adapter. Full recharge will occur over 12 to
16 hours. Before recharging the batteries you should
be deep cycled occasionally by allowing them to
completely discharge to maintain maximum battery
capacity. The NiCd batteries should last for several
years. However, it is a good idea to check them
every twelve months for signs of corrosion or
leakage. Always replace the whole set if any one
cell fails
Signal
Input
When
using the counter with an antenna for signal pick up,
random frequencies may appear on the display. This
is quite normal and is caused by the high gain of
the receiver circuits which amplify noise in the
absence of a strong readable signal. Never get the
unit too close to a transmitter as internal damage
will result.
Antenna
Selection
The
supplied telescopic antenna is best for general
purpose use. This is because its length can be
adjusted to suit the frequency required. Usually you
will want a shorter antenna for UHF and a fully
extended one for VHF / HF.
Reception
Distance From Transmitter
The
distance from which you will be able to receive
frequencies will depend upon the type and location
of the transmitting antenna, transmitter output
power and the frequency in use.
