General Safety:
The 3030 Directional Watt Meter should only be used for its intended purpose and never be connected to cables carrying hazardous voltages.
When handling NiMh batteries great care should be observed preventing
polarity reversal and short circuit as the batteries may explode or catch fire.
General Information.
Description:
The 3030 Directional Watt Meter is a versatile transmitter power analyzer
covering all major communication bands from 30MHz to 500MHz*. The
3030 Directional Watt Meter will measurement forward and reflected power
in the range from 1 Watt up to 100 Watts. The 3030 has a low resolution
frequency counter to show the operating frequency and for calibration table
look up. The 3030 Directional Watt Meter will calculate VSWR. The detection system will capture short transmitter pulses (20mS) and show frequency
in MHz. For longer transmitter periods the counter will show the frequency in
kHz. The 3030 Directional Watt Meter has peak and hold function to capture
power and frequency. Simple Menu navigation to change instrument settings. The 3030 Directional Watt Meter instrument is small, handy and light
weight battery operated with more than 4 hours of continuous operation on
the internal rechargeable NiMh low self-discharge cells. The usage of low
self-discharge cells brings several advantages, as the unit will retain its
charge for more than a year, and will sustain over 1000 charge cycles
Operation modes:
The 3030 Directional Watt Meter is as default operated like a conventional
thru line watt meter with the addition of SWR calculation and frequency
counting.
4
Battery and Charging:
The 3030 Directional Watt Meter is powered by 3 NiMh Low Self-discharge
AAA cells giving the instrument >4 hours of continuous operation when fully
charged.
The charging is done by USB from a PC or from a supplied charger via the
supplied USB cable. Charging current is approximately 250mA and full
charge is reached after 9 Hours of charging. The Charge indicator is always
lit when connected to your PC or the charger. The charging is a constant
current charge and can be left connect without damage to the battery cells. If
for any reason the batteries are replaced please replace with the same type
& rating.
In the event that the instrument has run out of battery, when arriving at a
customer site, please charge the unit for approx. 5 mins and leave the
charger connected, before commencing measurement.
Charge Indicator
The instrument can be use stand alone with alkaline AAA cells but NEVER
connect to USB or charger with alkaline cells!!
Warranty:
The 3030 Directional Watt Meter has a 1 year total warranty covering parts
and labor as long as the instrument has been used according to the instructions in this manual, and has not been subject to any abuse. Warranty will
cover the return shipment after repair.

Power On/Off
Pressing the ON/OFF button firmly will switch on the instrument.
A welcome screen will appear like this:

The instrument will run for the duration of the auto power off period or until
ON/OFF is pressed firmly again.

Menus continued:
Press Menu again to change setting!
Use Arrow buttons to change setting! And press ENTER to confirm change
and press ENTER again to return to measurement screen.
Measurement Modes:
In Normal mode the instrument will display Power and SWR when threshold
level is exceeded. The signal Icon will be lit. When the transmit signal disappear so will the Power and SWR.
In RMS Mode the instrument will display Power and SWR When threshold
level is exceeded. The signal Icon will be lit. When the transmit signal disappear the Power and SWR and Frequency will hold the reading and the hold
counter will run showing time from last signal was present. The No Signal
Icon is lit.

Menus continued:
The PEAK mode will find the maximum power level and decay the reading
slowly.
The P-Hold(Peak Hold) mode will find the maximum power level and hold
the reading.
The CONTRAST function can be used to adjust the LCD contrast.
The OFF TIME function is where the auto power off time limit is set. (Default
is 5 minutes)
AUTO FREQ can be used to enable or disable the frequency counter. If the
Signal is not stable or too weak the FIXED frequency option can be used.
The FREQUENCY must be set to the nearest 10MHz frequency with the
arrow buttons in FIXED frequency mode to have the correct calibration.
This is an example of fixed frequency option with and with out signal:

RTL:
Switches between displaying SWR and Return Loss as the 3rd measurement line.
Backlight:
The Backlight can be toggled on and off by the UP Arrow (see page 7)
All the menu setting can be combined in any configuration.
♦♦♦♦♦♦♦
Sensitivity of The 3030 Directional Watt Meter:
There are two conditions that must be met in order for the instrument to give a
reliable measurement. The counter must be stable enough to measure in MHz
resolution for the calibration table lookup to work. The next condition to be met is
the Forward Power level must be large enough to give a reliable SWR calculation.
In the figure below is a typical sensitivity plotted during automatic calibration of the
instrument.

Making Measurements
General Setup:
The 3030 Directional Watt Meter is a directional coupler in line Watt meter.
The 3030 Directional Watt Meter is to be inserted between a Transmitter
(Input) and an Antenna (Load) and will measure the transmitted power, the
reflected power and calculate the Standing Wave Ratio.
To make a calibrated measurement the frequency of the transmitter is
counted and displayed on screen.
Connecting Transmitter and Antenna:
Observe the outmost care when connecting antennas via cables , as these
cables can be connected to transmitters and /or power sources! Make sure
the transmitter is turned off! Make sure you have chosen the antenna you
intend to test!!
Connection to high power transmitters 150+Watts and/or other sources can
destroy the instrument or cause hazardous electrical conditions.
When connecting to the “N” female connectors on the instrument make sure
you are using either “N” male antenna cable connectors or an appropriate
adaptor.
Please observe that the use of adapters and cable connections of poor
quality may influence the SWR and give higher readings than the actual
antenna SWR. Once the antenna an transmitter has been connected to the
instrument you switch on The 3030 Directional Watt Meter on and select
your choice in the menu. By observing the screen you can see transmitted
power, reflected power, the calculated SWR and the measured frequency.
Antennas are usually designed to have a SWR below a given value within
the band for which it is designed. As an example a TETRA 390MHz antenna
could have the following specifications: Range 380 - 400 MHz at SWR less
than 2.0:1 typical 1.5:1.
General hints
Always refer to antenna and transmitter manufacturers specification! Antennas may have more than one resonance frequency! If the SWR value is
high or fluctuating the Antenna Cable may be broken or shorted!
Keep connectors clean and tight!
