Controls
1. Power Switch -This slide switch turns the counter on and initiates a
2 second test of all the LCD segments.
2. 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
Welfare Electronic Component Ltd.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.
Some typical distances are:
Cordless Phone 0.3 meters
Cellular Phone 3 -20 m
CB radio 2 -8 m
VHF Two Way Radio 3 -30 m
UHF Two Way Radio 3 -30 m
