1.1 Initial Check
1) Check whether packing case is damaged or not.
2) Take handheld spectrum analyzer out from packing
case, check whether it is damaged during transportation
or not.
3) According to packing list, check whether all accessories
and documents have been delivered with instrument.
If packing case or vibration-absorptive material is damaged,
firstly check whether instrument and accessories are
complete or not, and then test electrical properties of
handheld spectrum analyzer.
If instrument is damaged during transportation or some
accessories are missing, please inform us. We will repair or
exchange it as your requirements as soon as possible. Please
keep transportation materials for future packing. Please see
Chapter 6 “Repairing of Spectrum Analyzer” for disposition
ways.
1.2 Safety Precautions before use
1.2.1. Check Power
Handheld spectrum analyzer has two power supply modes,
i.e. supplied by power adapter and internal battery. The
input of power adapter adopts power cord interface, in line
with international safety standards.
If power of instrument is supplied by power adapter,
ground wire of AC power shall be reliably grounded.
Before start-up, make sure that ground wire of AC power
has been reliably grounded, and then put plug of power
cord in the standard three-pin socket. Don’t use power cord
not protected by grounded ground wire. Floating grounding
or bad grounding may lead to the damage of spectrum
analyzer, even personal injury.
1.2.2. Allowed Variation Range of Power Supply
Parameters
UTS1000 Series Handheld Spectrum Analyzer’s power
adapter adopts 100V~240V, 50Hz AC power. When
handheld spectrum analyzer normally works, requirements
of +9V power adapter for power has been listed in Table
1-1.
87623(5$7,1*0$18$/

In order to prevent or reduce mutual interference generated
by several equipments through power, in particular, peak
pulse interference generated by high-power equipments
possibly leads to hardware damage of spectrum analyzer, it
is better to use 220V/110V AC voltage-stabilized power to
supply power to adapter.
Table 1-1 Variation Range of Working Power
Power parameters Applicable range
Voltage 100V ~ 240V
Frequency 50Hz ~ 60Hz
Max.power consumption 20W
1.2.3. Selection of AC/DC Power Adapter
Suggest using special +9V power adapter provided by our
Company, or +9V power adapter accepted by your country
by inspection. Actual current of this product is
approximately 1.5A when it normally works, so power
adapter whose rated current is not less than 3A shall be used.
1.2.4. Static Protection
Static protection is always neglected by users. The damage
to instrument usually doesn’t appear immediately, but such
damage would greatly reduce reliability of instrument.
Therefore, if possible, adopt static protection measures,
and adopt proper static protection measures in daily work.
Warning
Before power-on and start-up of spectrum analyzer,
a
please firstly check whether voltage of power is
normal , to avoid the damage of equipment. At time
of first-time power-on, please read Section 3 “First-
time Power-on of Spectrum Analyzer” in this chapter.
Two anti-static measures are always adopted:
1) Combination of conductive table mat and wristband;
2) Combination of conductive floor mat and ankleband;
If two measures above are adopted at the same time, better
anti-static protection can be guaranteed. In case one is
adopted, only the former one is able to provide guarantee.
In order to ensure user’s safety, anti-static parts must be
equipped with at least 1Mȍresistor isolating from the
earth.

Correct application of anti-static technology can reduce
damages of elements and components:
1) Before connecting coaxial cable to spectrum analyzer
at the first time, make internal and external conductors of
cable separately contact with ground transiently.
2) Before contacting the core of connector or assembly,
workers must wear anti-static wristband.
3) Make sure all instruments have been correctly grounded,
so as to prevent accumulation of static.
1.3 First-time Power-on of Spectrum
Analyzer
Above anti-static measures can’t be used when voltage is
more than 500V!
UTS1000 Series Handheld Spectrum Analyzer is supplied
by power adapter or internal battery. When battery is fully
charged, internal battery can supply power for about 4
hours if spectrum analyzer works normally. Battery of
UTS1000 Series Handheld Spectrum Analyzer can’t store
power during transportation, so, such battery must be
charged before first-time use. Battery can be charged while
Before use, please firstly confirm voltage of AC power has
satisfied the requirement for input voltage of power adapter,
to avoid damage of equipment. Before putting AC plug into
instrument adapter, please firstly confirm power adapter is
qualified, or instrument may be damaged.
Before first-time start-up of instrument, AC power adapter
must be used to supply power, and get battery charged.
Otherwise, instrument may not be started or service life of
battery may be shortened.
Before start-up, please firstly connect output interface of
power adapter with power input interface in the lower
right of instrument. After correct connection of power
power adapter provided along with equipment supplies
power to instrument.
Battery not only can be charged when instrument is power
on, but also when it is power off. Time for charging is
about 4 hours when instrument is power on or off.

adapter, press yellow button in the lower left of front
panel, instrument starts. Start-up of instrument can be
completed in about one minute. When AC/DC power adapter
supplies power to instrument, mark “socket” is displayed in
the upper left of display screen; when battery supplies
power to instrument, mark “battery” is displayed in
corresponding position.
