Product Usage Instructions
- RF IN: Connect the transmitter or amplifier
- RF OUT: Connect the antenna or tuner
- POWER: Power switch – Turn on the power supply upwards
- CHARGE: Charging socket, TYPE-C type
- DATA: Data output socket (not used)
- The front panel features a 4.3 high-resolution colour display screen.
- The top right side of the screen displays the battery level and charging status. When connected to a charger, “CHARGING” will be displayed along with the battery voltage.
- Fwd Fwd displays two data, maximum power, and instantaneous power. The first digit shows the maximum RF power, and the second data displays instantaneous power.
- SWR range is displayed from 1.00 to 9.99. The progress bar will set different colours based on SWR value – green, yellow, and monochrome. A beep will prompt if SWR is too high.
FAQ
- Q: What does it mean if SWR displays 99.99?
- A: SWR displaying 99.99 indicates that the RFOUT socket is connected incorrectly or the antenna is invalid.
Introduction
- The mAT-S1500 is designed as an accurate instrument for monitoring station performance. It uses two RF-specific measurement chips, which can accurately measure the power and SWR of the RF system but cannot display information such as spectrum and impedance.
- The mAT-S1500 features a 4.3″ diagonal TFT colour display screen that displays the current RF power and SWR using bar and digital displays.
- This mAT-S1500 is equipped with two high-capacity 18650 lithium batteries, which can operate without the need for an additional power supply.
- By using the TYPE-C charging socket, users can easily use their phone charger to charge it. The charger is not an accessory to this instrument, and the user needs to prepare it themselves.
- The mAT-S1500 is an automated instrument that is very easy to use. It only has one power switch and can automatically set the range based on the input RF signal. It can also automatically set the colour of the screen background based on the brightness of the ambient light, helping users to better see the display.
- The shell of the mAT-S1500 is made using aluminium milling technology, which makes it very delicate and sturdy.

- Size: 14.1cm x 10.9cm x 8.1cm 5.6″W x 4.3″D x 3.2″H
- Weight: 1.21Kg
Rear panel
- RF IN RF signal input. Connect the transmitter or amplifier.
- RF OUT RF signal output. Connect the antenna or tuner.
- POWER Power switch. Turn on the power supply upwards.
- CHARGE Charging socket, TYPE-C type.
- DATA Data output socket is not used.
There is an indicator light on the left side of the charging socket, which will be illuminated during charging. After the battery is fully charged, this indicator light goes out. On the left side of this indicator light is an ambient light sensor. The mAT-S1500 will automatically set the colour of the screen background based on the light perceived by this sensor, making the display screen easier to read.
Front panel
- The front panel of the mAT-S1500 is a 4.3 “high-resolution colour display screen.
Battery and Charging
The top right side of the screen displays the battery level and charging
status. When a charger is connected, the text “CHARGING” will be displayed,
and the battery voltage will also be displayed. When the charger is removed,
the text “CHARGING” will disappear and the battery voltage display will also
turn off. When the mAT-S1500 is started, the battery voltage will also be
displayed for approximately 5 seconds.
The mAT-S1500 does not come with a charger. Users can use the TYPE-C charger
of most mobile phones to charge it. The charging voltage range is 4.5-5.5V,
exceeding the range will damage this meter. The maximum charging current
should not exceed 1A.
Important note 1: Please do not use this device when charging. The strong
electromagnetic waves emitted by the transmitter may disrupt the charger,
resulting in incorrect output voltage and damage to mAT-S1500. If mAT-S1500
detects that a charger is connected, a warning message will pop up to remind
the user. The display screen of the mAT-S1500 consumes almost all of its
electrical energy, and charging the mAT-S1500 during shutdown can greatly
shorten the charging time.
WARNING
Please do not use this meter during charging. Powerful radio waves may disrupt
your charger, output incorrect voltage, and damage your meter.
Important note 2: If the lithium battery inside the mAT-S1500 is reinstalled, please connect the charger to activate the protection circuit before it can start normally.
Fwd
Fwd displays two data, maximum power and instantaneous power.
The first digit displays the maximum RF power, and the second data displays
the instantaneous power. The following progress bar displays the instantaneous
power, and the cursor on the right is used to mark the maximum power.
Range: FWD has three ranges, 15W, 150W, and 1500W. When the mAT-S1500 starts,
the range is automatically set to 15W and an appropriate range is
automatically set based on the input RF signal. The range will only be
automatically set from small to large. If the user needs to return to a
smaller range, simply turn off the power and restart. The scale of the
progress bar will be automatically set according to the range.
Important: If you want to accurately measure RF power, please set your
transmitter to FM, FSK, RTTY, and CW mode, so that your transmitter can output
a stable carrier wave.
SWR: SWR also has two displays, a number and a progress bar. The display
range is 1.00-9.99. If SWR displays 99.99, it indicates that the “RFOUT”
socket is connected incorrectly or the antenna is invalid.
The progress bar will set different colours according to the value of SWR,
which are green, yellow and monochrome. When the SWR is too high, mAT-S1500
will emit a beep to prompt the user.
Shipping instructions
mAT-S1500 has two built-in lithium batteries, which may be restricted during
transportation. Please comply with relevant laws and requirements.
