41. IntroductionProfessional True RMS Industrial Digital Multimeter and TFT color LCD display,providing fast A/D converting sampling time, high accuracy , built-in dataloggingand Trend Capture feactures. It can trace any interrupted problems of the equipmentsand watch on without person. It is easy to find and solve the problems of theproduction 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, andContinuity plus Thermocouple Temperature. It can store and recall data. It featuresa waterproof, rugged design for heavy duty use. Proper use and care of this meterwill provide many years of reliable service2. SafetyTrue RMS Digital Multimeter User ManualWARNINGCAUTIONMAXThis symbol adjacent to another symbol, terminal or operatingdevice indicates that the operator must refer to an explanation inthe Operating Instructions to avoid personal injury or damage tothe meter.This symbol indicates a potentially hazardous situation,which if not avoided, could result in death or serious injury.This 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 mustnot be connected to a circuit point at which the voltage with respectto earth ground exceeds (in this case) 1000 VAC or VDC.This symbol adjacent to one or more terminals identifies them asbeing associated with ranges that may, in normal use, be subjectedto particularly hazardous voltages. For maximum safety, the meterand its test leads should not be handled when these terminals areenergized.WARNINGCAUTION

Safety InstructionsThis meter has been designed for safe use, but must be operated with caution.The rules listed below must be carefully followed for safe operation.apply voltage or current to the meter that exceeds the specified maximum:when working with high voltages.measure voltage if the voltage on the "COM" input jack exceeds 1000Vabove earth ground.connect the meter leads across a voltage source while the function switchis in the current, resistance, or diode mode. Doing so can damage the meter.discharge filter capacitors in power supplies and disconnect the powerwhen making resistance or diode tests.turn off the power and disconnect the test leads before opening the coversto replace the fuse or batteries.operate the meter unless the back cover and the battery and fuse coversare in place and fastened securely.If the equipment is used in a manner not specified by the manufacturer, theprotection provided by the equipment may be impaired.1-NEVER2-USE EXTREME CAUTION3-DO NOT4-NEVER5-ALWAYS6-ALWAYS7-NEVER3-3-3-3-3-3-True RMS Digital Multimeter User Manual

Operation is subject to thefollowing two conditions : (1) this device may not cause harmful interference, and(2) this device must accept any interference received, including interference thatmay cause undesired operation.Warning: Changes or modifications to this unit not expressly approved by theparty responsible for compliance could void the user’s authority to operate theequipment.This equipment has been tested and found to comply with the limits for aClass B digital device, pursuant to Part 15 of the FCC Rules. These limits aredesigned to provide reasonable protection against harmful interference in aresidential installation. This equipment generates, uses and can radiate radiofrequency energy and, if not installed and used in accordance with the instructions,may cause harmful interference to radio communications. However, there is noguarantee that interference will not occur in a particular installation. If this equipmentdoes cause harmful interference to radio or television reception, which can bedetermined by turning the equipment off and on, the user is encouraged to try tocorrect the interference by one or more of the following measures:
This device complies with FCC and Industry Canada RF radiation exposure limits set forth for general population (uncontrolled exposure).Rev.151027True RMS Digital Multimeter User ManualReorient 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 thereceiver is connected.Consult the dealer or an experienced radio/TV technician for helpThis device complies with Industry Canada licence-exempt RSS standard(s).Operation is subject to the following two conditions: (1) this device may not causeinterference, and (2) this device must accept any interference, including interferencethat may cause undesired operation of the device.Under Industry Canada regulations, this radio transmitter may only operate usingan antenna of a type and maximum (or lesser) gain approved for the transmitter byIndustry Canada. To reduce potential radio interference to other users, the antennatype 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 émetteurradiopeutfonctionner 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 risquesde brouillage radioélectriqueàl'intention des autresutilisateurs, il fautchoisir le typed'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 communicationsatisfaisante.Le présent appareilestconforme aux CNR d'Industrie Canada applicables auxappareils radio exempts de licence. L'exploitationestautorisé e aux deuxconditionssuivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateurde l'appareildoit accepter tout brouillage radioélectriquesubi,même si le brouillageestsusceptible d'encompromettre le fonctionnementThis device must not be collocated or operating in conjunction with any other antenna or transmitter.
