GRID DIP METER
DM-4061 1.5 ~ 250 MHz
Description:
This unit is a transistorized dip meter for rapidly checking circuits
and components in receivers, transmitters, antennas, etc., in the
1.5 to 250MHz range. It is designed for many applications in the 1.5
to 250MHz range. It is designed for many applications in Amateur
Radio stations and service shops.
A multipurpose transistor dip meter covering the range 1.5MHz to
250MHz in six overiapping ranges. With the 3-position function
switch at 'Osc' and one of the six colls supplied plugged into the
socket at the back, the unit can be used as a dip metter or
bsorption wavematter. The precise frequency required is set on a
large multicolour dial with the six ranges shown on it. The rotary
edge 'sensitivity' control mane be used to adjust the sensitivity of
the metter on the front of the instrument to dive on-scale readings.
The metter is calibrated 0 to 1 in steps.
The metter can also be used in this mode for shortwave receiver
testing with CW signals. With AM signals, the function switch should
be set to "Mod" and a 2KHz tone will be added to the carrier
frequency. An audio signal output is also provided for connection
to a crystal earpiece. With the function switch to at 'Batt check', the
meter can be used to check the battery condition.
The coil socket can also be used to connect a crystal in the range
1MHz to 15MHz wich will produce an output at the crystal
frequency that can be modulated by putting the function switch
at 'MOD'. The metter is supplied with the six coils, a 3.5mm mono jck
plug for the "phone" output, and a PP3 battery.
