Heavy Duty True RMS Digital Multimeter
EN
Heavy Duty True RMS Digital Multimeter/English
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.
This WARNING symbol indicates a potentially hazardous situation,
WARNING
which if not avoided, could result in death or serious injury.
CAUTION
This
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.
CAUTION symbol indicates a potentially hazardous situation,
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

PER IEC1010 OVERVOLTAGE INSTALLATION CATEGORY
OVERVOLTAGE CATEGORY I
Equipment of OVERVOLTAGE CATEGORY I is equipment for connection to circuits
in which measures are taken to limit the transient overvoltages to an appropriate low
level.
Note- Examples include protected electronic circuits.
OVERVOLTAGE CATEGORY II
Equipment of OVERVOLTAGE CATEGORY II is energy-consuming equipment to
be supplied from the fixed installation.
Note- Examples include household, office, and laboratory appliances.
OVERVOLTAGE CATEGORY III
Equipment of OVERVOLTAGE CATEGORY III is equipment in fixed installations.
Note- Examples include switches in the fixed installation and some equipment for
industrial use with permanent connection to the fixed installation.
OVERVOLTAGE CATEGORY IV
Equipment of OVERVOLTAGE CATEGORY IV is for use at the origin of the installation.
Note- Examples include electricity meters and primary over-current protection
equipment
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
Frequency, Resistance, Capacitance,
Duty Cycle, Diode Test, Continuity
Temperature
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
above earth ground.
4-NEVER connect the meter leads across a voltage source while the function switch
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
when making resistance or diode tests.
6-ALWAYS turn off the power and disconnect the test leads before opening the covers
to replace the fuse or batteries.
7-NEVER operate the meter unless the back cover and the battery and fuse covers
are in place and fastened securely.
If the equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.

10 Replacing the Batteries
Refer to Figure and replace the batteries as follows:
1.Turn the Meter off and remove the test leads from the terminals.
2.Remove the battery door assembly by using a standardblade screwdriver to turn
the battery door screw one-half turn counterclockwise.
3. Replace the batteries with 7.4 volt charge batteries Observe proper polarity.
4. Reinstall the battery door assembly and secure it by turning the screw one-half
turn clockwise.
. Replacing the Fuses
7-11
Referring to Figure , examine or replace the Meter's fuses as follows:
1.Turn the Meter off and remove the test leads from the
terminals.
2.Remove the battery door assembly by using a standardblade screwdriver to turn
the battery door screw one-half turn counterclockwise.
3.Remove the fuse by gently prying one end loose, then
sliding the fuse out of its bracket.
4.Install only specified replacement fuses.
5.Reinstall the battery door assembly and secure it by turning the screw one-half
turn clockwise

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.
