1. Introduction
Professional True RMS Industrial Digital Multimeter and TFT color LCD display,
providing fast A/D converting sampling time, high accuracy , built-in datalogging
and Trend Capture feactures. It can trace any interrupted problems of the equipments
and watch on without person. It is easy to find and solve the problems of the
production equipments, providing Bluetooth technology and memory the datasheets.
It is much more safe measurements.
This meter measures AC/DC Voltage, AC/DC Current, Resistance, Capacitance,
Frequency(electrical & electronic), Duty Cycle, Diode Test, Insulation Test, and
Continuity plus Thermocouple Temperature. It can store and recall data. It features
a waterproof, rugged design for heavy duty use. Proper use and care of this meter
will provide many years of reliable service
2. Safety
This symbol adjacent to another symbol, terminal or operating
device indicates that the operator must refer to an explanation in
the Operating Instructions to avoid personal injury or damage to
the meter.
WARNING
CAUTION
MAX
This WARNING symbol indicates a potentially hazardous situation,
which if not avoided, could result in death or serious injury.
This CAUTION symbol indicates a potentially hazardous situation,
which if not avoided, may result damage to the product.
This symbol advises the user that the terminal(s) so marked must
not be connected to a circuit point at which the voltage with respect
to earth ground exceeds (in this case) 1000 VAC or VDC.
This symbol adjacent to one or more terminals identifies them as
being associated with ranges that may, in normal use, be subjected
to particularly hazardous voltages. For maximum safety, the meter
and its test leads should not be handled when these terminals are
energized.

This symbol indicates that a device is protected throughout by double
insulation or reinforced insulation.

3. Safety Instructions
This meter has been designed for safe use, but must be operated with caution.
The rules listed below must be carefully followed for safe operation.
1-NEVER apply voltage or current to the meter that exceeds the specified maximum:
Input Protection Limits
Function
V DC or V AC
mA AC/DC
A AC/DC
Maximum Input
1000VDC/AC rms
500mA 1000V fast acting fuse
10A 1000V fast acting fuse
(20A for 30 seconds max every
15 minutes)
Frequency, Resistance, Capacitance, 1000VDC/AC rms
Duty Cycle, Diode Test, Continuity
Temperature
1000VDC/AC rms
Surge Protection: 8kV peak per IEC 61010
2-USE EXTREME CAUTION when working with high voltages.
3-DO NOT measure voltage if the voltage on the "COM" input jack exceeds 1000V
3-above earth ground.
4-NEVER connect the meter leads across a voltage source while the function switch
3-is in the current, resistance, or diode mode. Doing so can damage the meter.
5-ALWAYS discharge filter capacitors in power supplies and disconnect the power
3-when making resistance or diode tests.
6-ALWAYS turn off the power and disconnect the test leads before opening the covers
3-to replace the fuse or batteries.
7-NEVER operate the meter unless the back cover and the battery and fuse covers
3-are in place and fastened securely.
If the equipment is used in a manner not specified by the manufacturer, the
3-protection provided by the equipment may be impaired.

The term stands for “Root-Mean-Square,” which
represents the method of calculation of the voltage
or current value. Average responding multimeters
are calibrated to read correctly only on sine waves
and they will read inaccurately on non-sine wave or
distorted signals. True rms meters read accurately
on either type of signal.

FCC and IC warning:
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions : (1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that
may cause undesired operation.
Warning: Changes or modifications to this unit not expressly approved by the
party responsible for compliance could void the user’s authority to operate the
equipment.
NOTE: This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment
does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
31
True RMS Digital Multimeter User Manual
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
Consult the dealer or an experienced radio/TV technician for help
This device complies with Industry Canada licence-exempt RSS standard(s).
Operation is subject to the following two conditions: (1) this device may not cause
interference, and (2) this device must accept any interference, including interference
that may cause undesired operation of the device.
Under Industry Canada regulations, this radio transmitter may only operate using
an antenna of a type and maximum (or lesser) gain approved for the transmitter by
Industry Canada. To reduce potential radio interference to other users, the antenna
type and its gain should be so chosen that the equivalent isotropically radiated power
(e.i.r.p.) is not more than that necessary for successful communication.
Conformémentà la réglementationd'Industrie Canada, le présent émetteur
radiopeutfonctionner avec uneantenne d'un type et d'un gain maximal (ouinf érieur)
approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques
de brouillage radioélectriqueàl'intention des autresutilisateurs, il fautchoisir le type
d'antenne et son gain de sorteque la puissance isotroperayonn ée équivalente
(p.i.r.e.) ne dépasse pas l'intensité nécessaireà l'établissement d'une communication
satisfaisante.
Le présent appareilestconforme aux CNR d'Industrie Canada applicables aux
appareils radio exempts de licence. L'exploitationestautorisé e aux deux
conditionssuivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur
de l'appareildoit accepter tout brouillage radioélectriquesubi,même si le brouillageest
susceptible d'encompromettre le fonctionnement
This device complies with FCC and Industry Canada RF radiation exposure limits set forth for general population (uncontrolled exposure).
