True RMS Digital Multimeter User Manual 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 This WARNING symbol indicates a potentially hazardous situation, which if not avoided, could result in death or serious injury. CAUTION This CAUTION symbol indicates a potentially hazardous situation, which if not avoided, may result damage to the product. MAX 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. 4

True RMS Digital Multimeter User Manual 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 Maximum Input V DC or V AC 1000VDC/AC rms mA AC/DC 500mA 1000V fast acting fuse A AC/DC 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. 6

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). This device must not be collocated or operating in conjunction with any other antenna or transmitter. Rev.151027
