1Maintenance and Safety Considerations
1.1 Calibrating the Meter
All the instruments have analog circuitry:
preamplifiers, filter, etc.-whose performance can
change over time. A regular schedule of calibrations
will keep your instrument in optimal condition to
support you design, troubleshooting, and
manufacturing work.
It is recommended to calibrate and verify the meter
at least once a year to ensure that the meter meets
the original designed performance and specifications.
To avoid damaging the default calibration data stored
in a non-violated memory, a calibration to the meter
can only be done by an authorized service center and
qualified personnel with appropriate equipment.
For detailed information on the calibration
procedures, please contact factory or authorized
distributor.
Environmental condition: Calibration or verification

test should be performed under laboratory condition
whereby the ambient temperature or relative
humidity can be controlled.
Warm up: Allow up to at least 5 minutes warm-up
before performing calibration to the meter. After
exposure or storage in a high humidity (condensing)
environment, relative recovery period is required
essentially.

1.2 About Battery, Adapter and Firmware
upgrade
Please charge-discharge the battery in every 3 months
to extend battery life!
Warning：Danger of explosion if the battery is
incorrectly replaced. Replace only with the same type
battery recommended. Do NOT dispose of batteries in
a fire. Do NOT place batteries in the trash. Batteries
must be recycled or disposed of properly.
CAUTION: Recharge the battery only in the meter. If
left unused, a fully charged battery will discharge
itself over time.
Never use a damaged or worn-out adapter or battery.
Charging the batteries internally, even while the
analyzer is powered off, the analyzer may keep warm.
To avoid overheating, always disconnect the analyzer
from the AC adapter before storing the analyzer into
the soft carrying case.
CAUTION: Connect the automotive adapter to the

DS2460Q QAM Analysis Meter Operation Manual

power output connector for IT equipment, when
charging the battery on your automotive.
CAUTION: Temperature extremes will affect the ability
of the battery to charge. Allow the battery to cool
down or warm up as necessary before use or charging.
Storing a battery in extreme hot or cold temperatures
will reduce the capacity and lifetime of a battery.
Battery storage is recommended at a temperature of
less than 25°C.
The analyzer cannot be used in the standard soft
carrying case for more than 1 hours if the ambient
temperature is higher than 35°C.
CAUTION: Use only the original AC-DC adapter or
originally supplied battery for the power source.
Whether the meter work or power off, you can charge
the battery.
1 Insert the battery in the analyzer.
2 Plug in the AC-DC adapter and switch on the
external power.
3 The charge indicator lights, indicating that the

battery is charging. When the battery is fully charged,
the green charging indicator turns off.
The charging time for a fully depleted battery, is
approximately four hours.
If the meter is power on, the charging time is longer.
CAUTION: In updating process, there must be a
constant power supply to for at least 10 minutes. If
power fails during the updating process it can cause
damage to the instrument.
Danger: DS2460 provide option VFL (Visual Fault
Locator), VFL output signal (red light) has danger:
In any case, user forbidden directly use the VFL
output port towards himself or other person eyes.
Doing so may causethe irradiated people damageto
your eyesightand even blindness!

2General Introduction
DS2460Q is new model with color screen and high
performance, which is developed for digital cable TV
analysis by Deviser. This model can measure and
display most indexes of Digital TV(Channel Power,
MER, BER, Constellation Diagram); Analog
TV(Single-frequency Level, Carrier Level of Full
Channels Spectrum, HUM).Also DS2460Qcan measure
Trunk Voltage, Battery Voltage, Spectrum Analysis and
channel Scanning.
DS2460Qhasmicro USB port for communicating with
PC and also the PC software – TOOLBOX which can
make files management and analysis. DS2460Q also
has one RJ-45 port which used for network function
PING.
